Deep Groove Ball Bearings SKF 6234 M/C3

The SKF 6234 M/C3 deep groove ball bearing combines dimensions of 170 × 310 × 52 mm with a brass cage and increased C3 bearing clearance for thermally stressed industrial applications.

This single-row deep groove ball bearing 6234 M/C3 from SKF is designed for predominantly radial loads whilst also accommodating axial forces in both directions. The design consists of standard rolling-element steel (100Cr6) for the inner ring, outer ring and rolling elements. As an open rolling bearing without integrated sealing washers, this design is intended for direct installation in enclosed housings where lubrication is supplied externally via oil or grease.

What is the 6234 M/C3 deep groove ball bearing suitable for under high loads?

Due to its dimensions – with a 170 mm bore and an outer diameter of 310 mm – the bearing is primarily used in heavy-duty industrial drives, industrial gearboxes and heavily loaded shaft bearings. The brass cage ensures that the rolling elements remain stable even under vibrations, varying speeds and shock loads. As there is no flange or groove on the outer ring, the component can be fitted flush into cylindrical housing bores.

What are the characteristics of the brass cage and the C3 bearing clearance?

The C3 designation indicates an increased radial clearance compared to the standard. This additional clearance compensates for operational thermal expansion when the shaft and housing reach different temperatures or when tight fits are specified. The bearing is suitable for a temperature range of -20 to +150 degrees. The brass cage is characterised by high mechanical stability and low friction, even under demanding operating conditions.
