Deep Groove Ball Bearings SKF 6301 -Z

Single-row SKF deep groove ball bearing 6301-Z, dimensions 12x37x12 mm, with a Z-type cover on one side and a sheet steel cage, for industrial applications.

The SKF 6301-Z deep groove ball bearing is a radial rolling bearing designed for combined loads with a predominantly radial component. As it is manufactured from standard rolling bearing steel (100Cr6), the single-row bearing can accommodate not only radial forces but also axial forces in both directions. This design is characterised by a single-sided sheet metal cover, which protects the interior from coarse particles, whilst the open opposite side allows for targeted relubrication within the housing assembly.

For which applications is the 6301-Z deep groove ball bearing designed?

This bearing is primarily used in rotating shaft assemblies and general machinery applications where combined radial and axial loads occur. The single-row design enables high rotational speeds with smooth and quiet running. Typical installation scenarios include housing systems in which lubricant is fed to the bearing from the open side, whilst the Z-cover effectively prevents grease from escaping or solid foreign particles from entering.

What is the function of the single-sided Z-cover?

The Z-cover plate acts as a non-contact gap seal made from profiled sheet steel. Unlike abiding sealing elements, this design does not generate any additional frictional torque, allowing the bearing to achieve its full speed potential without incurring additional thermal stress. In combination with the standard radial bearing clearance and the standardised tolerance class P0/PN (ABEC 1), the design is suitable for reliable shaft support within a defined temperature range of –20 to +150 degrees Celsius.
