Deep Groove Ball Bearings FAG 6308 -2RSR-C3

The FAG 6308 -2RSR-C3 deep groove ball bearing, measuring 40x90x23 mm, with a ground seal on both sides and a C3 clearance, offers protection against contamination at elevated operating temperatures.

The 6308 -2RSR-C3 deep groove ball bearing is a single-row rolling bearing made from standard 100Cr6 bearing steel, manufactured to tolerance class P0/PN or ABEC 1. It accommodates radial loads as well as axial forces in both directions. A sturdy sheet steel cage guides the rolling elements evenly in the deep raceways. The factory-fitted seal, with sealing lips that rub against the raceway on both sides, ensures that the lubricant remains within the bearing chamber whilst keeping out dirt particles and moisture.

What is the 6308-2RSR-C3 deep-groove ball bearing suitable for in operation?

This rolling bearing is designed for applications where dusty environmental conditions prevail and thermal loads occur. The sliding 2RSR seals protect the raceways against the ingress of foreign particles and premature wear. With an operating temperature range of -20 to +100 degrees, the component is suitable for a wide range of industrial bearing applications involving increased heat generation during continuous operation.

What are the characteristics of the C3 bearing clearance and the 2RSR seal?

The C3 designation indicates a slightly increased radial bearing clearance compared with the standard version. If the shaft and inner ring heat up during operation, or if fits cause the inner ring to expand, the increased radial clearance compensates for this thermal expansion without the bearing becoming stressed. The RSR contact seals on both sides protect the internal space and help ensure low-maintenance operation of the bearing assembly.
