•   No risk of breakage
•   Lighter weight

Product Details:

• Separable design: Shaft washer, housing washer, cylindrical roller and cage thrust assembly can be mounted separately.
• Extended bearing service life: To prevent stress peaks, the roller ends are relieved slightly to modify the line contact between the raceway and rollers.

Product Details:

• 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:

• The number of roller rows (one, two or four)
• The type of cage (with, without or special designs)
• Bearings with cage can accommodate heavy radial loads, rapid accelerations and high speeds.
• Full complement bearings (without cage) incorporate a maximum number of rollers and are therefore suitable for very heavy radial loads at moderate speeds.
• SKF high-capacity cylindrical roller bearings combine the high load carrying capacity of a full complement bearing with the high speed capability of a bearing with cage.
• The configuration of the inner and outer ring flanges (position and number of guide flanges)

• High load carrying capacity
• High stiffness
• Accommodate axial displacement: Except for bearings with flanges on both the inner and outer rings.
• Low friction: (Roller end / flange contact area)
  The open flange design, together with the roller end design and surface finish, promote lubricant film formation resulting in lower friction and higher axial load carrying capacity.
• Long service life: The logarithmic roller profile reduces edge stresses at the roller/raceway contact and sensitivity to misalignment and shaft deflection.
• Enhanced operational reliability: The surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.
• Separable and interchangeable: The separable components of SKF cylindrical roller bearings are interchangeable. This facilitates mounting and dismounting, as well as maintenance inspections.

Four-row cylindrical roller bearings are used almost exclusively for the roll necks of rolling mill stands, calenders and roller presses. Because they are normally mounted with an interference fit on the roll neck, four-row cylindrical roller bearings are well suited for rolling mill applications where the rolling speed is high.

Because four-row cylindrical roller bearings can accommodate only radial loads, they are mounted together with deep groove or angular contact ball bearings, or with tapered roller bearings (either radial or thrust design) which accommodate the axial loads.

• Exceptional high load carrying capacity: Because of their high number of rollers, four-row cylindrical roller bearings are suitable for very heavy radial loads.
• Low friction: (Roller end / flange contact area) The open flange design, together with the roller end design and surface finish, promote lubricant film formation resulting in lower friction.
• Long service life: The logarithmic roller profile reduces edge stresses at the roller/raceway contact and sensitivity to misalignment and shaft deflection.
• Enhanced operational reliability: The surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.
• Separable and interchangeable: The separable components of SKF four-row cylindrical roller bearings are interchangeable. This facilitates mounting and dismounting, as well as maintenance inspections.
• High speed capability: The cage designs are suitable for high speeds, rapid accelerations and peak loads.
• Low cross-sectional height: The low cross-sectional height of four-row cylindrical roller bearings allows for relatively large roll neck diameters compared to the roll diameter.

Product Details:

Electric motors, generators and associated equipment are at risk when an electric current passes through their bearings. This can damage the contact surfaces of rolling elements and raceways in the bearings (electrical erosion) and rapidly degrade the grease. An additional risk in electric motors and generators comes from high frequency currents caused by the inherent stray capacitance. The risk of damage increases where the application uses a frequency converter.

Insocoat Bearings:

Are designed to prevent electric current from passing through the bearing

Have the external surfaces of either their inner or outer ring coated with an insulating aluminium oxide layer, by applying a sophisticated plasma-spray process for an outstanding quality finish

Are a very cost-effective solution compared with other insulation methods

 
Bearing Features:

Protection against electrical erosion: With insulating properties integrated into the bearing, INSOCOAT bearings can improve reliability and increase machine uptime by virtually eliminating the problem of electrical erosion.

High electrical resistance: The aluminium oxide coating provides a minimum electrical resistance of 200 M??? and can withstand voltages up to 3 000 V DC.

Consistent electrical performance: Plasma-spray coatings are normally hygroscopic and, therefore, vulnerable to penetration caused by condensation. To protect against this effect, INSOCOAT bearings are treated with a unique sealant.

 
Assortment:
The standard assortment of INSOCOAT bearings listed here constitutes the most commonly used sizes and variants of:

Single row deep groove ball bearings.
