Deep Groove Ball Bearings FAG 6212 -2RSR

The 6212-2RSR deep groove ball bearing from FAG Wälzlager protects the raceways with seals that seal on both sides, whilst offering compact dimensions of 60 × 110 × 22 mm.

The 6212-2RSR deep groove ball bearing is a single-row radial ball bearing made from standard rolling-element steel (100Cr6) with a 60 mm bore, 110 mm outer diameter and 22 mm width. This rolling bearing primarily absorbs radial forces and also supports shafts under axial loads in both directions. FAG Rolling Bearings manufactures this version with a sheet steel cage and standard radial clearance in tolerance class P0 (ABEC 1).

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

Designs featuring 60 mm shafts utilise the 6212 -2RSR deep groove ball bearing under combined loads in dusty or damp environmental conditions. The scraping seal lips keep dirt particles and splash water away from the raceways. The cylindrical outer ring, which has no groove, fits directly into suitable housing bores. The specified temperature range of –20 to +100 degrees allows for use in various thermal environments.

What is the function of the 2RSR seal in the bearing?

The designation -2RSR refers to contact seals mounted on both sides, made from elastic sealing material. These scraping sealing lips rest against the inner ring and keep dirt and moisture out of the bearing interior. At the same time, they minimise grease leakage, which often means that external sealing systems on the housing are no longer required. When designing the bearing, it must be borne in mind that, due to their design, sliding seals generate higher friction than non-contact cover plates.
