Deep Groove Ball Bearings SKF 6001 -2Z

The SKF 6001-2Z deep groove ball bearing, with its compact dimensions of 12x28x8 mm, offers reliable protection against dirt particles whilst minimising friction.

The 6001-2Z deep-groove ball bearing is a single-row radial ball bearing made from standard rolling-element bearing steel (100Cr6) in the SKF Explorer design. The design primarily accommodates radial forces as well as moderate axial forces in both directions. Thanks to its double-sided protection with non-contact cover plates, this rolling bearing is suitable for applications where low friction losses and protection against coarse foreign particles are required. It operates within a temperature range of -20 to +120 degrees and features a guided sheet steel cage.

What is the 6001-2Z deep groove ball bearing suitable for?

Design engineers and maintenance technicians primarily use this bearing in compact rotating units. Typical applications include high-speed shaft bearings, compact drive units and general mechanical engineering. As the end shields are designed to be non-contacting, no additional frictional torques are generated by rubbing sealing lips. This makes it ideal for applications involving higher speeds where contamination from dry dust or swarf needs to be prevented. The cylindrical outer ring, which has no groove, fits precisely into housing bores.

What do the tolerance classes P6 and P5 mean for this bearing?

This SKF deep-groove ball bearing combines dimensional accuracy of class P6 with running accuracy to P5. This results in tighter manufacturing tolerances than with standard tolerances, which contributes to improved concentricity and smoother vibration behaviour. To fully utilise this precision, it is recommended that the shaft and housing seats are of a corresponding precision. With standard radial bearing clearance, the bearing is suitable for standard fit selections and moderate thermal expansion of the shaft during operation.
