Deep Groove Ball Bearings SKF 6210 -2RS1/C3

The SKF 6210 -2RS1/C3 deep groove ball bearing, measuring 50x90x20 mm, with a ground seal on both sides and C3 clearance, offers a tried-and-tested solution for industrial drives.

The SKF 6210 -2RS1/C3 deep groove ball bearing is a single-row radial ball bearing for shaft diameters of 50 mm. The outer ring and inner ring are made of standard roller bearing steel (100Cr6) with a cylindrical outer surface without a flange or groove. Inside, balls made of roller bearing steel, guided by a sturdy sheet steel cage, ensure smooth movement. As a sealed unit, this rolling bearing primarily accommodates radial forces as well as moderate axial forces in both directions. The design complies with tolerance class P0 (standard).

For which loads and conditions is the 6210-2RS1/C3 bearing suitable?

This roller bearing is primarily used in rotating machine components subject to medium to high radial loads, where the bearing location must be protected against particles or splash water. Typical applications include industrial drives with rotating shafts where moderate additional axial forces occur. As it is manufactured from roller bearing steel, the bearing is designed for operating temperatures between –20 and +120 degrees Celsius.

What does the combination of a 2RS1 seal and C3 clearance mean?

The designation 2RS1 refers to sealing lips fitted on both sides that make it difficult for dust, moisture and foreign particles to penetrate. At the same time, the lubricant remains inside the bearing. The designation C3 indicates a slightly increased radial clearance compared with the standard version. This increased radial clearance compensates for thermal expansion when the inner and outer rings reach different temperatures during operation, or when tight fits on the 50 mm shaft constrict the bearing radially.
