Deep Groove Ball Bearings SKF 6034 M/C3

The SKF 6034 M/C3 single-row deep groove ball bearing (170x260x42 mm) combines a brass cage with increased C3 clearance for demanding industrial applications.

The 6034 M/C3 deep groove ball bearing is an open, single-row radial ball bearing for shafts with a diameter of 170 mm. Manufactured from 100Cr6 rolling-element bearing steel, this design accommodates radial forces as well as axial loads in both directions. The open design, without sealing washers, allows for direct lubrication via the machine’s surrounding oil or grease circuit and helps to minimise friction losses during continuous operation.

Under what operating conditions is the 6034 M/C3 deep groove ball bearing used?

This large bearing is used in general mechanical engineering for applications involving dynamic loads or significant vibrations. Thanks to its solid brass cage, the design is engineered to withstand stronger vibrations, accelerations and inertial forces. The design is particularly suitable for sealed housings, in which an external lubricant supply feeds the raceways and keeps external contaminants out.

What advantages do the brass cage and C3 clearance offer in this design?

The suffixes M and C3 denote specific technical adaptations. The brass cage guides the rolling elements precisely and is characterised by high strength and low wear. The designation C3 stands for an increased radial bearing clearance compared with the standard clearance. This additional clearance compensates for operational thermal expansion between the inner and outer rings, as well as the press-fit stresses associated with tight fits, ensuring that the bearing maintains reliable operation within a temperature range of -20 to +150 degrees.
