Deep Groove Ball Bearings SKF 61822

The SKF 61822 deep-groove ball bearing combines a 110 mm bore with a narrow cross-section for space-saving designs and radial load-carrying capacity.

This single-row deep-groove ball bearing 61822, made from standard rolling-element bearing steel (100Cr6), is characterised by its small cross-section in relation to its comparatively large shaft diameter. It primarily supports radial loads and guides the shaft in both the axial and radial directions. With key dimensions of 110 mm inner diameter, 140 mm outer diameter and a width of 16 mm, the component enables compact housing designs in general machinery and fixture construction.

What advantages does the 61822 thin-section deep-groove ball bearing offer in confined installation spaces?

Designs with severely limited radial installation space utilise this narrow series to achieve compact external dimensions. The ratio between the 110 mm bore and the 140 mm outer diameter allows larger shafts to be supported whilst maintaining a small housing size. The bearing primarily absorbs radial forces and also supports axial forces in both directions. The design as a single-row bearing without a flange or groove on the outer ring facilitates flush mounting in cylindrical housing bores.

What are the distinctive features of the open design and the sheet steel cage?

As an open rolling bearing, this design has no manufacturer-fitted cover or sealing washers, allowing lubricant to reach the rolling elements freely. Lubrication and sealing against environmental influences are provided by the surrounding structure. The integrated sheet steel cage keeps the rolling elements spaced apart and is suitable for operating temperatures ranging from –20 to +120 degrees. Manufacture to tolerance class P0/PN (ABEC 1), in conjunction with standard radial bearing clearance, ensures a precise fit on the shaft and within the housing.
