Industrial Ball Bearings

Product Details:

Four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads in both directions. For a given axial load, a limited radial load can also be supported (Load ratio). The bearings are separable, i.e. the outer ring with ball and cage assembly can be mounted separately from the two inner ring halves.
Both inner ring halves of SKF Explorer four-point contact ball bearings have a recessed shoulder. This improves oil flow when the bearing is used in combination with an SKF cylindrical roller bearing (fig. 1). In addition, these recesses can be used to facilitate dismounting.

Bearing Features:

• Accommodates axial loads in both directions
• Less axial space
  These bearings take up considerably less axial space than double row bearings.
• High load carrying capacity
  A large number of balls are incorporated, giving the bearing its high load carrying capacity.
• Separable design
  The split inner ring leads to easier mounting and dismounting of the bearing. 
• Improved oil flow
• Limited inner ring deformation when subjected to high clamping forces

Product Details:

Extremely thin-section ball bearings and roller bearings contributing to downsizing, weight saving, and reduction of torque loss of robots, construction equipments, and industrial machinery.

Features:

• Low frictional and irregular torque ensure highly efficient power transmission and smooth rotating performance.
• The high accuracy of the bearings enables excellent high-speed performance.

Product Details:

SKF polymer ball bearings can be made from a variety of materials and material combinations:

• Polymer rings
• Balls made of stainless steel, glass, polymer or other materials
• A polymer cage

 

Polymers have significantly different properties than steel. Therefore, polymer ball bearings are typically used in applications where resistance to moisture or chemicals is essential and steel bearings cannot be used or only with certain restrictions. In those applications, polymer ball bearings are an excellent solution from both a technical and economic perspective as they are characterized by the following properties:

• Corrosion and chemical resistant
• High wear- and fatigue-resistant polymer
• Self-lubricating (no lubricant required)
• Low coefficient of friction
• Quiet running
• Lightweight
• High specific strength (strength-to-weight ratio)
• High dimensional stability due to low tendency to creep
• Low life cycle costs
• Electrical insulator
• Good damping properties
• High temperature usage (some bearings)
• Integrated functions for special bearings

 

These properties make polymer ball bearings appropriate for the following industries and applications:

• Food and beverage industry
• Medical and pharmaceutical industry
• Chemical industry
• Textile industry
• Electrical industry
• Photographic industry
• Modelling and lightweight applications
• Vacuum applications
• Office products
• Measuring equipment
• Material handling and transportation
• Consumer goods
• Electroplating
• Heating and air conditioning

Designs and variants:

The standard assortment of SKF polymer ball bearings provided here constitutes the most commonly used sizes of:

• Single row deep groove ball bearings
• Thrust ball bearings

 

Both bearing designs have uninterrupted raceways and are non-separable. Standard bearings are only available as open bearings (without seals or shields).

Other polymer ball bearings and units (fig. 3) are available on request. Customized polymer bearings can be manufactured economically, even in small quantities. Integrated functions (e.g. gearing, specific shape of the bore) that can reduce the number of components and assembly costs are also possible. Examples of those bearings, which are not provided here, include:

• Inch single row deep groove ball bearings
• Full complement single row deep groove ball bearings
• Capped single row deep groove ball bearings
• Double row deep groove ball bearings
• Track runner bearings
• Insert bearings and ball bearing units
• Special size bearings
• Bearings or components made of other materials
• Bearing units with integrated functions

 

Compared with same-sized steel bearings, polymer ball bearings cannot accommodate the same heavy loads or high speeds and they do not have the same narrow operating clearance nor the same precise shaft positioning capability.

Product Details:

Product Details:

SKF thrust ball bearings are manufactured as single direction (fig. 1) or double direction (fig. 2) thrust ball bearings. They are designed to accommodate axial loads only and must not be subjected to any radial load.

Bearing Features:

• Separable and interchangeable: The separable components of SKF thrust ball bearings are interchangeable. This facilitates mounting and dismounting, as well as maintenance inspections.
• Initial misalignment: Bearings with sphered housing washer can accommodate initial misalignment.
• Interference fit: Shaft washers have a ground bore to enable an interference fit. The bore of the housing washer is turned and always larger than the shaft washer bore.

Product Details:

SKF single row angular contact ball bearings can accommodate axial loads in one direction only. This type of bearing is typically adjusted against a second bearing. Their bearing rings have an upper and a lower shoulder and are non-separable.

Bearing Features:

• High load carrying capacity: The lower shoulder enables a large number of balls to be incorporated in the bearing, giving it a relatively high load carrying capacity.
• Good running properties: Rapid accelerations and decelerations are possible.
• Easy mounting of universally matchable bearings: No adjustment is needed for correct internal clearance or preload.

Product Details:

This type of ball bearing is recommended when alignment of the shaft and housing is difficult and the shaft may flex. The outer ring has a spherical raceway and its center of curvature coincides with that of the bearing; therefore, the axis of the inner ring, balls and cage can deflect to some extent around the bearing center. Pressed steel cages are usually used. Since the contact angle is small, the axial load capacity is low. The permissible dynamic misalignment is approximately 0.07 to 0.12 radian (4 to 7 degrees) under normal loads.

However, depending on the surrounding structure, such an angle may not be possible.

Product Details:

Double row deep groove ball bearings are very suitable for bearing arrangements where the load carrying capacity of a single row bearing is inadequate. For the same bore and outside diameter, double row bearings are slightly wider than single row bearings in the 62 and 63 series, but have a considerably higher load carrying capacity.
Double row deep groove ball bearings are only available as open bearings (without seals or shields).

Features:

• SKF double row deep groove ball bearings are fitted with two snap-type, ball centred glass fibre reinforced PA66 cages (designation suffix TN9, fig. 2).
• When used at high temperatures, some lubricants can have a detrimental effect on polyamide cages. For additional information about the suitability of cages, refer to Cages.

Product Details:

Deep groove ball bearings are the most widely used bearing type, especially in electric motors. SKF hybrid deep groove ball bearings:

• Are non-separable
• Are suitable for high speeds
• Accommodate radial loads and axial loads in both directions because their uninterrupted raceway grooves have a close osculation with the balls
• Are manufactured to SKF Explorer bearing quality
• Are available with a bore diameter ranging from 5 to 180 mm
• With a bore diameter d ≤ 45 mm, are most suitable for electric motors in the power range 0,15 to 15 kW as well as for power tools and high-speed drives
  SKF hybrid deep groove ball bearings in this size range are the most cost-effective solution against electrical erosion.

 

Basic Design Bearings:

• Are available with a bore diameter d ≥ 10 mm

 

Sealed Bearings:

• Use the same seals as described under Capped bearings
• Are lubricated for the life of the bearing and should not be washed or relubricated
• Are virtually maintenance-free

 

When capped bearings must operate under certain conditions, such as very high speeds or high temperatures, grease may appear between the inner ring and capping device. For bearing arrangements where this would be detrimental, appropriate actions should be taken.

Greases for sealed bearings:

• The standard grease, suitable for most common operating conditions of electric motors and generators, is indicated by the designation suffix WT.
• For additional information about greases, refer to Selecting a suitable grease.

 

Grease life:

• The estimated grease life is typically at least twice as long as for same-sized bearings with steel balls (→ Grease life for capped bearings).

 

XL hybrid bearings:

• Are identified by the designation suffix VA970
• Are designed to meet the application requirements for electric generators in larger wind turbines.
• Are available for the most commonly used generator sizes (→ product table)

 

Cages:
SKF hybrid deep groove ball bearings are fitted with one of the following cages:

• A stamped steel cage, riveted, ball centred (no designation suffix)
• A glass fibre reinforced PA66 cage, snap-type, ball centred (designation suffix TN9)
• A glass fibre reinforced PEEK cage, snap-type, ball centred (designation suffix TNH)
• A machined brass cage, riveted, ball centred (designation suffix M)
• For additional information, refer to Cages.
• When used at high temperatures, some lubricants can have a detrimental effect on polyamide cages. For additional information about the suitability of cages, refer to Cages.

 

Hybrid bearings with special steel rings and coatings:

For specific application requirements, hybrid bearings can be customized:

• Bearing rings stabilized for temperatures ≤ 300 °C (570 °F)
• Bearing rings made of through-hardened stainless steel for enhanced corrosion and wear-resistance and with good high-temperature properties
• Bearing rings made of through-hardened stainless steel for cryogenic temperatures
• Bearing rings made of high-temperature tool steel
• Ring coating with zinc chromate or thin dense chromium for corrosion protection
• Ring coating based on molybdenum for low friction, especially in vacuum or gas applications

Product Details:

Thrust ball bearings are classified into those with flat seats or aligning seats depending on the shape of the outer ring seat (housing washer). They can sustain axial loads but no radial loads. For Single-Direction Thrust Ball Bearings, pressed steel cages and machined brass cages are usually used The cages in Double- Direction Thrust Ball Bearings are the same as those in Single-Direction Thrust Ball Bearings of the same diameter series.

Features:

• Available in two designs: single direction and double direction.
• To accommodate initial misalignments in an assembly both designs are available with spherical aligning seats or aligning seat washers.
• High quality steel-ultra clean steel to extend bearing life by up to 80%.
• Advanced Grease Technology — NSK lubricants that can extend grease life and performance.
• High Grade Balls — Quiet and smooth operation even at high speed.
• Optional seating rings take initial misalignment.

Product Details:

The NSK bearing unit is a combination of a radial ball bearing, seal, and a housing of high-grade cast iron or pressed steel, which comes in various shapes. The outer surface of the bearing and the internal surface of the housing are spherical, so that the unit is self-aligning. The inside construction of the ball bearing for the unit is such that steel balls and retainers of the same type as in series 62 and 63 of the deep groove ball bearing are used. A duplex seal consisting of a combination of an oil-proof synthetic rubber seal and a slinger is provided on both sides.

Product Details:

Single row deep groove ball bearings with filling slots have a filling slot in both the inner and outer rings to accommodate more balls than standard deep groove ball bearings.
Filling slot bearings have a higher radial load carrying capacity than bearings without filling slots, but their axial load carrying capacity is limited. They are also unable to operate at the same high speeds as bearings without filling slots.
Deep groove ball bearings with filling slots are available open or with shields on one or both sides. They are also available with or without a snap ring groove. Open bearings that are also available with shields may have recesses in the outer ring.
Large size deep groove ball bearings with filling slots, without cage, are available on request.

Product Details:

Single row deep groove ball bearings are available capped (with seals or shields) or open. Open bearings that are also available capped may have recesses in the ring side faces.
SKF inch bearings in the EE(B), RLS and RMS series are intended as aftermarket items and, therefore, SKF recommends not using these bearings for new bearing arrangement designs.
SKF can also supply bearings with a tapered bore. For detailed information, contact SKF.

Product Details:

Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are available open or sealed. The bearings are insensitive to angular misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection.

Bearing Features:

• Accommodate static and dynamic misalignment: The bearings are self-aligning like spherical roller bearings or CARB bearings.
• Excellent high-speed performance: Self-aligning ball bearings generate less friction than any other type of rolling bearing, which enables them to run cooler even at high speeds.
• Minimum maintenance: Because of low heat generation, the bearing temperature is lower, leading to extended bearing life and maintenance intervals.
• Low friction: Very loose conformity between balls and outer ring keeps friction and frictional heat at low levels.
• Excellent light load performance: Self-aligning ball bearings have low minimum load requirements.
• Low noise: Self-aligning ball bearings can reduce noise and vibration levels, for example, in fans.
