Deep Groove Ball Bearings FAG 61844 -C2

The FAG 61844 -C2 deep-groove ball bearing, with dimensions of 220 × 270 × 24 mm and reduced C2 bearing clearance, offers precise guidance within a compact installation space.

This single-row deep-groove ball bearing 61844 -C2 from FAG combines a large bore diameter of 220 mm with a particularly narrow cross-section. Designed as an open rolling bearing without integrated sealing washers, it can be lubricated directly via the surrounding system. The sheet steel cage guides the rolling elements, made from standard rolling-bearing steel, evenly within the deep raceways. You receive a dimensionally stable component for designs that require high concentricity whilst maintaining compact housing dimensions.

What installation conditions does the FAG 61844-C2 deep groove ball bearing require?

Design engineers primarily select this design for bearing arrangements with large shaft diameters where there is limited radial installation space. The bearing primarily accommodates radial loads and also supports the shaft under moderate axial forces. Thanks to its wide temperature range of –30 to +200 degrees, this design is suitable for thermally demanding environments, provided that an external housing seal prevents the ingress of contaminants.

What does the reduced radial clearance (C2) mean for your application?

The C2 designation indicates a radial bearing clearance that is below the standard tolerance class. This reduced radial bearing clearance minimises operational play, which supports precise shaft guidance and minimises vibrations. When installing the bearing, pay close attention to the fits between the shaft and the housing bore. As tight fits further reduce the residual clearance, this bearing requires precise coordination of the installation dimensions and operating temperatures.
