Barrel Roller Bearings FAG 20308 -TVP-C3

The FAG 20308 -TVP-C3 spherical roller bearing, measuring 40 x 90 x 23 mm, can accommodate high radial loads and automatically compensates for misalignment.

The 20308 -TVP-C3 spherical roller bearing is a single-row, angular-contact roller bearing designed for demanding industrial applications. Thanks to its barrel-shaped rolling elements and the hollow-spherical outer ring raceway, this bearing compensates for misalignment between the shaft and the housing without edge pressure. This open-type bearing from FAG has a bore of 40 mm, an outer diameter of 90 mm and a width of 23 mm. As it is manufactured to standard tolerance P0/PN or ABEC 1, the roller bearing fits into standardised housing fits.

What is the 20308 -TVP-C3 spherical roller bearing suitable for?

Design engineers primarily select the 20308 -TVP-C3 spherical roller bearing for applications where heavy radial forces are present and shaft deflection may occur. By compensating for angular misalignment, this design helps to reduce uneven wear on the roller raceways. Typical applications include shaft mountings subject to high radial loads and misalignments. In combination with suitable pedestal or flanged bearing housings, the open unit provides a practical solution for stationary shaft guides.

What are the benefits of the TVP polyamide cage and the C3 clearance?

The suffix TVP denotes a solid polyamide cage, which ensures quiet running and reduces the weight of the bearing assembly. Together with the lubricant, this material determines the permissible temperature range of –30 to +120 degrees Celsius. The C3 designation also indicates a slightly increased radial bearing clearance. This increased radial distance between the rollers and raceways helps to prevent the bearing from becoming unduly stressed when it heats up during operation or in the case of tight fits.
