SKF needle roller and cage assemblies are self­-contained, ready-­to­-mount bearings. In applications where the shaft and housing bore can serve as raceways, the assemblies can be used to create bearing arrangements that require minimal radial space.

Bearing Features:

• Lowest cross section among rolling bearings: In applications where less space is available, needle roller and cage assemblies offer a very compact solution.
• High load carrying capacity: Owing to their large number of rollers, needle roller and cage assemblies have a high load carrying capacity.
• High stiffness: Because of their large number of small-diameter rollers, needle roller and cage assemblies have high stiffness.

Product Details:

Spherical roller bearings have two rows of symmetrical rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis. The centre point of the sphere in the outer ring raceway is at the bearing axis.

Bearing Features:

• Accommodate misalignment: Spherical roller bearings are self-aligning like self-aligning ball bearings or CARB bearings.
• High load carrying capacity: Spherical roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions.
• Long service life: The rollers are manufactured to such tight dimensional and geometrical tolerances that they are practically identical in a roller set. The symmetrical rollers self-adjust, providing optimal load distribution along the roller length and together with the special profile prevent stress peaks at the roller ends.
• Low friction: Self-guiding rollers keep friction and frictional heat at low levels. A floating guide ring guides unloaded rollers so that they enter the load zone in the optimal position.
• Robust: All SKF spherical roller bearings contain strong window- or prong-type cages.

Product Details:

CARB toroidal roller bearings have one row of long, slightly barrel-shaped symmetrical rollers and torus-shaped raceway profiles. They are non-locating bearings and accommodate exclusively radial loads. CARB bearings are often used to replace the non-locating spherical roller bearing in a locating/non-locating bearing arrangement.

Bearing Features:

• Accommodate misalignment: CARB bearings are self-aligning like spherical roller bearings or self-aligning ball bearings.
• Accommodate axial displacement: CARB bearings compensate for thermal expansion of the shaft like cylindrical or needle roller bearings.
• Wide assortment of dimension series: CARB bearings are available with the same boundary dimensions as corresponding spherical roller bearings, self-aligning ball bearings, cylindrical roller bearings and needle roller bearings.
• Long service life: The special roller profile prevents stress peaks at the roller ends.
• Low friction: Self-guiding rollers keep friction and frictional heat at low levels.
• Improved wear resistance: All CARB bearings are upgraded SKF Explorer bearings.
• Low noise: CARB bearings can reduce noise and vibration levels, for example, in paper machines and fans.

SKF tapered roller thrust bearings are designed to accommodate heavy axial loads and peak loads. The bearings are very stiff and require little axial space.

Bearing Features:

• Separable design: The shaft and housing washers and the roller and cage thrust assemblies of tapered roller thrust bearings with cages can be mounted separately.
• Low friction: The optimized roller end design and surface finish on the flange promote lubricant film formation, resulting in lower friction. This also reduces frictional heat and flange wear.
• Long service life: Depending on the design, crowned or logarithmic raceway profiles optimize the load distribution along the contact surfaces, reduce stress peaks at the roller ends, and reduce the sensitivity to misalignment compared with conventional straight raceway profiles.
• Consistency of roller profiles and sizes: The rollers incorporated in SKF tapered roller thrust bearings are manufactured to such close dimensional and geometrical tolerances that they are practically identical. This provides optimal load distribution, and reduces noise and vibration.

Split cylindrical roller bearings are intended primarily for bearing arrangements which are difficult to access or for cranked shafts. It is advantageous to use them in all cases where the maintenance or replacement of non-split bearings would require considerable extra time-consuming effort and would cause long and expensive or even inadmissible machine downtime. Some common applications for split cylindrical roller bearings are cold tube rolling mill (Pilger mill) crankshafts, bucket wheel excavators, conveyor pulleys, rolling mill drive spindles as well as large critical ventilation installations.
SKF now offer a full range of SKF Cooper split cylindrical roller bearings and SKF Cooper split bearing units (including housings). Please visit SKF Cooper for further data

Product Details:

SKF needle roller thrust bearings are fitted with a form-stable cage to reliably retain and guide a large number of needle rollers. Needle roller thrust bearings provide a high degree of stiffness within a minimum axial space. In applications where the faces of adjacent machine components can serve as raceways, needle roller thrust bearings take up no more space than a conventional thrust washer.

Bearing Features:

• Accommodate heavy axial loads and peak loads: The very small diameter deviation of the rollers within one assembly enables these bearings to accommodate heavy axial loads and peak loads.
• 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:

SKF drawn cup needle roller bearings have a deep drawn, thin-walled outer ring. Drawn cup needle roller bearings are typically used in applications where the housing bore cannot be used as a raceway for a needle roller and cage assembly, but where a very compact and economical bearing arrangement is required. These bearings are mounted with a tight interference fit in the housing. That enables a simple and economic design of the housing bore, as shoulders or snap rings are not required to locate the bearing axially.

The drawn cup of hardened steel and the needle roller and cage assembly of these bear­ings form a non­-separable unit.

Bearing Features:

• Low cross section: In applications where less space is available, drawn cup needle roller bearings enable downsizing.
• High load carrying capacity and stiffness: Owing to their large number of rollers, drawn cup needle roller bearings have a high load carrying capacity and stiffness.
• Good running properties

Product Details:

Four-row tapered roller bearings can accommodate combined (radial and axial) loads at low to moderate speeds. They are used almost exclusively in work roll applications such as rolling mills.

Bearing Features:

Depending on their design, four-row tapered roller bearings provide the following main features and benefits:

• Long service life: The four-cup design (four separate outer rings) provides optimal load distribution over all four rows of rollers.
• Enhanced operational reliability: Optimized surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.
• Improved wear resistance: In particular, SKF Explorer bearings are made of extremely clean and homogenous steel and undergo a unique heat treatment, which improve the resistance to wear.
• Improved sealing performance with less leakage and less frictional heat: The optimized seal design ensures high protection against external contamination but keeps friction and frictional heat low. This seal design also provides a better retention of lubricant, minimizes environmental impact and reduces maintenance costs.
• Equal load carrying capacity for sealed and open bearings: The optimized and compact seal design enables identical internal design.
• Total bearing interchangeability: Bearings with and without intermediate rings as well as open and sealed bearings are available with identical external dimensions. This allows total bearing interchangeability of current standard design bearings with those without intermediate rings and/or with optimized seal design.
• Separable mounting and simpler inspection: Optimized designs without intermediate rings enable to dismount and separate the cage and roller assemblies and seals. This facilitates mounting, dismounting and also maintenance inspection routines.
• Axial space-saving and cost-effective solution for roll necks: The roll necks can be relatively short, no separate axial bearings are required and identically designed chocks can be used on both sides of the roll.
• Simple axial location on roll necks: Tighter inner ring width tolerances facilitate the tolerancing and dimensioning of surrounding components.

Product Details:

SKF spherical roller thrust bearings have specially designed raceways and asymmetrical rollers. The bearings can accommodate axial loads acting in one direction and simultaneously acting radial loads. The load is transmitted between the raceways via the rollers at an angle to the bearing axis, while the flange guides the rollers.

Bearing Features:

• High load carrying capacity: The large number of rollers, which have an optimum conformity with the washer raceways, enables the bearings to accommodate heavy axial and simultaneously acting radial loads.
• Accommodate misalignment: SKF spherical roller thrust bearings are self-aligning and can accommodate misalignment.
• Separable design: SKF spherical roller thrust bearings are separable, making it possible to mount and dismount the housing washer separately from the shaft washer and roller and cage assembly. In addition this facilitates maintenance inspections.
• High speed capability: The cage designs and the optimum conformity of the rollers with the washer raceways make the bearings suitable for relatively high speeds.
• Long service life: The special roller profile reduces edge stresses at the roller/raceway contact.
• Low friction: The optimized roller end / flange contact keeps frictional heat at low level, even at high speeds.

Product Details:

SKF high-capacity cylindrical roller bearings have the high load carrying capacity of full complement bearings and the high speed capability of bearings with cage. They are designed for applications such as industrial gearboxes, wind turbine gearboxes and mining equipment.

Bearing Features:

• High load carrying capacity: The cage bars are displaced relative to the roller pitch diameter to enable the rollers to be placed closer to each other, creating room for additional rollers.
• High stiffness: The increased number of rollers increases radial stiffness.
• High speed capability: The cage designs are suitable for high speeds, rapid accelerations and peak loads.
• Long service life

The black oxide coating of rings and rollers (designation suffix L4B) contributes to extended service life by improving:

• Smearing damage resistance
• Running-in properties and reducing friction
• Performance under poor lubrication conditions
• Chemical resistance (from agressive oil additives)
• Corrosion resistance

Product Details:

SKF needle roller bearings with machined rings are made of carbon chromium bearing steel. SKF supplies these bearings with or without flanges on the outer ring, in a wide range of series and sizes. SKF also supplies them with or without an inner ring.

Bearing Features:

• Low cross section: In applications where less space is available, needle roller bearings offer a very compact solution.
• High load carrying capacity: Despite their low cross sectional height, they have a high load carrying capacity.
• Separable design: The possibility of assembling inner and outer rings separately permits interference fits for shaft and housing and also enables easy maintenance inspections.
• High stiffness: Owing to their large number of small-diameter rollers, needle roller bearings with machined rings have high stiffness.
• Accommodate axial displacement: Except for bearings with flanges on both the inner and outer rings, needle roller bearings with machined rings can accommodate axial displacement.
