Deep Groove Ball Bearings SKF 6056 M/C3

The SKF 6056 M/C3 single-row deep groove ball bearing combines dimensions of 280 × 420 × 65 mm with a robust brass cage and increased C3 clearance for heavy-duty industrial applications.

The SKF 6056 M/C3 deep groove ball bearing is an open, single-row radial ball bearing for shafts with a diameter of 280 mm. Manufactured from standard rolling-element bearing steel 100Cr6, this large bearing accommodates high radial forces as well as axial guidance loads on both sides. Thanks to its outer ring without a ring groove and its design without integrated seals, this component is specifically suited to designs with an external lubrication system and separate housing seals. It meets the requirements of tolerance class P0 (standard tolerance or ABEC 1) for continuous industrial use.

What is the 6056 M/C3 deep groove ball bearing suitable for?

Design engineers primarily use the 6056 M/C3 deep groove ball bearing in heavy machinery and plant engineering, where large shaft diameters are subjected to sustained radial forces. Typical applications include heavy-duty industrial drives and large rotating units with an external lubrication supply. As this is an open bearing, the lubricant can be circulated or replenished within the housing as required. At the same time, the component absorbs axial forces in both directions and guides rotating machine parts with precision.

What are the advantages of a brass cage and C3 bearing clearance?

The combination of a brass cage and a slightly increased radial clearance (C3) supports operation under demanding thermal conditions. A solid brass cage reliably withstands vibrations and high acceleration forces. The C3 bearing clearance compensates for heat-induced expansion of the shaft and inner ring during operation without the rolling elements becoming jammed. With a permissible temperature range of -20 to +150 degrees, the component thus retains the necessary mobility.
