Deep Groove Ball Bearings SKF 6228

The single-row SKF deep groove ball bearing 6228, measuring 140 × 250 × 42 mm, is an open rolling bearing that offers reliable running characteristics under combined loads.

The SKF 6228 deep groove ball bearing is a radial rolling bearing for industrial applications with a bore of 140 mm, an outside diameter of 250 mm and a width of 42 mm. The design is made from standard rolling bearing steel (100Cr6) and houses the rolling elements in a single row of balls. Manufactured to tolerance class P0/PN (ABEC 1), this unit primarily accommodates radial forces as well as moderate axial forces in both directions.

For which operating conditions is the 6228 deep groove ball bearing suitable?

This radial ball bearing is primarily used in industrial bearing arrangements subject to combined loads. The deep raceway geometry promotes smooth running whilst ensuring even force distribution across the rolling elements. As this bearing is designed for a temperature range of -20 to +120 degrees, it covers typical thermal conditions in continuous industrial operation. The cylindrical outer ring, without a flange or groove, allows for installation in standard housing bores.

What are the advantages of the open design with a sheet steel cage?

As an open bearing, this model has no integrated sealing washers. This allows lubricant to reach the raceways and balls unhindered, which aids heat dissipation and enables use in closed, externally sealed lubrication systems. The built-in sheet steel cage keeps the rolling elements spaced apart and withstands typical mechanical stresses during operation. Fitted with a standard radial bearing clearance, the component requires no special adjustments when installed on precisely fitted shaft seats.
