Deep Groove Ball Bearings FAG 6212 -2RSR-C3

The FAG 6212 -2RSR-C3 deep-groove ball bearing combines a 60 mm bore with contact seals on both sides and increased C3 bearing clearance for industrial applications subject to thermal stress.

The FAG 6212 -2RSR-C3 deep groove ball bearing is a single-row rolling bearing designed for predominantly radial and moderate axial loads. With key dimensions of 60 mm inner diameter, 110 mm outer diameter and 22 mm width, the design is suitable for a wide range of shaft mountings. The use of standard 100Cr6 rolling bearing steel for the rings and rolling elements ensures the unit retains its dimensional stability. An integrated sheet steel cage guides the balls evenly in the deep raceways, ensuring low-vibration operation.

What is the 6212-2RSR-C3 deep groove ball bearing suitable for in operation?

This radial ball bearing is well-suited to industrial drive systems and rotating bearings operating at medium to high speeds. Typical applications include situations where rotating shafts require reliable support and where dirt or moisture is present in the environment. The sealing discs, which abut on both sides, keep foreign particles out and prevent the lubricant from leaking. Thanks to the cylindrical outer ring without a groove or flange, you can mount the bearing directly onto standard shafts and in precisely fitted housing bores.

When is the combination of a 2RSR seal and C3 bearing clearance required?

The -2RSR-C3 version is designed for operating conditions involving temperature differences between the shaft and the housing. The designation C3 indicates a slightly increased radial bearing clearance. If the inner ring expands due to operating heat within the permissible range of -20 to +100 degrees, the additional clearance prevents the components from becoming stressed. The sliding seals seal off the internal space on both sides. This ensures that the grease filling remains in the bearing, thereby reducing maintenance requirements in enclosed machines.
