Deep Groove Ball Bearings FAG 6021

FAG 6021 deep groove ball bearing: A single-row, open rolling bearing measuring 105 x 160 x 26 mm, designed for a wide range of radial and axial loads in mechanical engineering.

The FAG 6021 deep groove ball bearing is a single-row radial ball bearing for industrial applications with a shaft diameter of 105 mm. As an open rolling bearing without integrated sealing rings, it allows unobstructed access to lubricant via oil or grease circulation systems. It primarily absorbs radial forces and supports shafts in both axial directions. Manufactured from standard roller bearing steel 100Cr6, the component withstands mechanical stresses during continuous operation.

In which installation environments does the 6021 deep-groove ball bearing prove its worth?

This 6021 deep-groove ball bearing is primarily used for combined loads in general mechanical engineering and in industrial gearboxes. Design engineers make specific use of the 26 mm cross-sectional width, combined with an outer diameter of 160 mm, for installation spaces with a shaft diameter of 105 mm. As the bearing is of an open design, it is suitable for installation locations where external lubrication is provided, for example within a gearbox housing. When properly lubricated, the component operates within a temperature range of -20 to +150 degrees.

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

The integrated sheet steel cage guides the rolling elements with low friction and keeps the bearing’s own weight low. The open design allows for a flexible choice of lubricant tailored to the system. With standard radial bearing clearance and tolerance class P0/PN (corresponding to ABEC 1), the rolling bearing meets standard requirements for precise concentricity. External seals must be incorporated into the design to prevent the ingress of dirt and moisture.
