SKF spherical roller bearings are one of the most comprehensive bearing series on the market, offering excellent self-aligning performance and high load-carrying capacity. They can withstand radial loads and bidirectional axial loads, making them particularly suitable for applications involving heavy loads, vibration, and shaft deflection.
SKF spherical roller bearings offer the most comprehensive product series on the market. The standard bearing product range includes:
① CC-type bearings: Feature two window-type stamped steel cages, an inner ring without flanges, and a floating guide ring guided by the inner ring.
② CA-type bearings: Feature a fork-type machined brass cage, an inner ring with flanges on both sides, and a floating guide ring guided by the inner ring.
③ E-type bearings: Feature two window-type stamped steel cages, an inner ring without flanges, and a floating guide ring guided by the inner ring (for d ≤ 65 mm) or the cage (for d > 65 mm).
④ Sealed bearings
* Have the same characteristics and internal design as open spherical roller bearings.
* Standard configuration is cylindrical bore.
* Pre-filled with grease and cannot be washed.
* Equipped with contact seals on one or both sides. These seals are made from one of the following materials:
NBR nitrile rubber with a steel (suffix CS or RS)
HNBR hydrogenated nitrile rubber with a steel (suffix CS5 or RS5)
FKM fluor rubber with an embedded steel (suffix CS2)
⑤ Bearings for vibrating machinery applications
* Available in the 223 product series.
* Available with cylindrical or tapered bore.
* Standard internal radial clearance is C4.
* Available in the following designs:
E/VA405 bearings feature two surface-hardened window-type stamped steel cages, an inner ring without flanges, and a floating guide ring guided by the inner ring or cage.
EJA/VA405 and CCJA/W33VA405 bearings feature two surface-hardened window-type stamped steel cages, an inner ring without flanges, and a floating guide ring guided by the outer ring raceway.
⑥ Bearings for wind energy applications
* Available in the 240 series (d ≥ 530 mm).
* Designed for wind turbine main shafts.
* Feature an optimized internal geometry, equipped with large-diameter rollers and a larger contact angle, improving axial load-carrying capacity.
* Feature a rolling element-guided cast iron cage, enhancing cage robustness.
* Do not have a floating guide ring.
* Feature a wider annular lubrication groove on the outer ring surface with six lubrication holes within the groove.
* Identified by the suffix BC in the product tables.
The designation of an SKF spherical roller bearing consists of a basic designation + prefix + suffix.
• Basic designation: Typically composed of numbers (sometimes including letters), indicating the bearing series, dimensions, and type.
Series code (first three digits): Indicates the width and diameter series.
Dimensions (last two digits): Indicates the bore diameter.
• Prefix: Typically indicates bearing components or special designs.
• Suffix: Indicates variants in internal design, cage, clearance, tolerance, heat treatment, etc. This is key to distinguishing different structures.
