Deep Groove Ball Bearings FAG 62308 -2RSR

The 62308 -2RSR deep-groove ball bearing from FAG Rolling Bearings, with dimensions of 40 x 90 x 33 mm and a seal that seals on both sides, offers reliable protection with normal radial clearance.

The 62308 -2RSR deep groove ball bearing is a single-row rolling bearing with a 40 mm bore, an outer diameter of 90 mm and a width of 33 mm. This FAG roller bearing design primarily accommodates radial forces as well as axial loads in both directions. Manufactured from standard 100Cr6 bearing steel for the inner ring, outer ring and rolling elements, the design features a sheet steel cage. An outer ring without a flange or groove facilitates cylindrical mounting in the housing seat.

What is the 62308-2RSR deep groove ball bearing suitable for?

This radial ball bearing is suitable for applications in general mechanical engineering where shafts with a diameter of 40 mm are used. The seals, which seal on both sides, protect the raceways from ingress of dirt and moisture. At the same time, they retain the lubricant inside the bearing. With a permissible temperature range of -20 to +100 degrees, the bearing is suitable for industrial environments with moderate temperature conditions.

What is the function of the 2RSR seal and the bearing clearance?

The suffix 2RSR denotes abiding contact seals fitted on both sides. Their sealing lips make elastic contact with the inner ring, providing effective protection against particles and splash water. With standard radial bearing clearance (tolerance class P0/PN or ABEC 1), the operating clearance corresponds to the standard values for rolling bearings. When designing the bearing, care must be taken to select appropriate fit tolerances and operating temperatures to prevent seizing.
