Deep Groove Ball Bearings SKF 6215 -Z

The SKF 6215-Z deep groove ball bearing, with dimensions of 75 × 130 × 25 mm, is designed to support radial loads in a sealed housing.

The 6215-Z deep groove ball bearing is a single-row radial ball bearing made from standard roller bearing steel (100Cr6) for medium to high speeds. It primarily accommodates radial forces as well as axial loads in both directions. The SKF version complies with tolerance class P0 (ABEC 1). Maintenance and design engineers utilise the standardised dimensions of 75 mm inner diameter and 130 mm outer diameter, with a width of 25 mm, to ensure a precise fit when installing the bearing into existing assemblies.

In which applications is the 6215-Z deep groove ball bearing used?

This single-row deep-groove ball bearing accommodates combined radial and axial loads in rotating shaft arrangements. The geometry, featuring deep raceways, ensures even force distribution across the shaft and housing. As the outer ring is manufactured without a groove or flange, the component can be fitted flush into cylindrical housing bores. Its use is recommended where stable shaft guidance is required with normal radial clearance, without the need for additional axial flange fixing.

What is the function of the single-sided Z-cover on this bearing?

The single-sided cover shield protects the interior from coarse foreign particles, whilst the open opposite side allows targeted lubricant access into the housing. Designs with a closed housing side or lubricant supply from the rear utilise this partial protection. The integrated sheet steel cage guides the rolling elements and retains its dimensional stability within a temperature range of -20 to +150 degrees. It is fitted with the closed cover facing the side exposed to dirt, in order to protect the raceways from particle ingress.
