Product catalog summary

Overview: This document provides detailed specifications and modification codes for Timken® Spherical Roller Bearings (SRBs). It includes information on bore sizes, dimension series, cage types, radial internal clearance, and various modification codes to meet specific application requirements.

Bore Sizes: Bore sizes are categorized into small, medium, and large. For small and medium sizes, the bore code multiplied by 5 gives the bore size in mm. For large sizes, the bore code directly represents the bore size in mm.

Dimension Series: Bearings are classified based on width and outside diameter, with series numbers indicating these dimensions.

Bore Styles: Two bore styles are available: cylindrical (no designation) and tapered (indicated by 'K' in the part description).

Modification Codes: Various codes indicate specific modifications such as cage type, radial internal clearance, and lubrication features. Examples include:

Cage Types: EJ, EM, EMB, CJ, YM, YMB, YMD, indicating different cage materials and designs.
Radial Internal Clearance (RIC): Codes like C2, C3, C4, C5, C6 indicate different levels of clearance.
Lubrication and Material Codes: W33 for standard lubrication holes, W40 for carburizing grade steel, and others for specific features.

Timken Offerings: The document lists various part numbers for Timken SRBs, indicating compatibility with other brands like SKF, FAG, and NSK.
