Deep Groove Ball Bearings SKF 6312

The SKF 6312 deep groove ball bearing is an open radial ball bearing with a 60 mm bore, an outer diameter of 130 mm and a width of 31 mm, designed for a wide range of industrial applications.

The single-row deep groove ball bearing 6312 is one of the most versatile rolling bearings used in mechanical and plant engineering. It primarily absorbs radial forces and also supports the shaft axially in both directions. As part of the SKF Explorer range, this component features optimised internal geometries and fine raceways made from standard rolling-element bearing steel (100Cr6). The sheet steel cage guides the rolling elements at operating temperatures ranging from –20 to +120 degrees Celsius.

What loads does the 6312 deep groove ball bearing accommodate?

The bearing is suitable for applications where radial forces predominate whilst axial forces occur on both sides. Rotating shafts in industrial drives transmit the forces directly via the inner and outer rings. As the outer ring is designed without a flange or ring groove, the bearing fits flush into cylindrical housing bores. The symmetrical design transfers alternating axial and radial loads to the surrounding components.

What are the distinctive features of the open design of the 6312?

This model has no integrated seals or cover plates. As a result, liquid oil or grease from the housing circulation system circulates inside the bearing, which aids heat dissipation and keeps rotational resistance low. An external housing seal prevents lubricant loss and the ingress of contaminants. Thanks to the standard radial bearing clearance and tolerance class P0 (ABEC 1), the bearing is suitable for standardised fits on shafts and housings.
