Deep Groove Ball Bearings SKF 6015 -Z

The SKF 6015-Z deep groove ball bearing, with dimensions of 75 × 115 × 20 mm and a single-sided sheet metal cover, offers reliable protection against coarse dirt.

The SKF 6015-Z deep groove ball bearing is a single-row radial ball bearing in the Explorer performance class, made from standard 100Cr6 rolling-element steel. It is designed to withstand predominantly radial loads as well as moderate axial loads in both directions. Thanks to the single-sided Z-cover, one side remains protected against the ingress of solid dirt particles, whilst the open opposite side allows for relubrication via the housing if required. The bearing is manufactured to a higher dimensional accuracy in tolerance class P6 with standard running accuracy PN.

What is the 6015-Z deep groove ball bearing suitable for?

This design is primarily used in bearing arrangements where one side of the housing is already protected within an oil or grease chamber. The non-contact Z-cover prevents any additional friction losses, ensuring the bearing remains suitable for high speeds. The sheet steel cage reliably guides the rolling elements during operation. Furthermore, the bearing covers a wide operating temperature range from –20 to +150 degrees Celsius, which allows for use in thermally demanding operating environments.

What are the advantages of the single-sided Z-cover during installation?

The asymmetrical design, featuring only one metal cover plate, requires correct orientation within the bearing seat during installation. Align the protected ‘Z’ side towards the potential source of contamination to shield the interior of the bearing. Fresh lubricant enters the rolling element chamber directly via the uncovered side, which is advantageous in centralised lubrication systems or oil bath operation. As this model has a standard radial bearing clearance, it is recommended that standard shaft and housing seats be used to ensure play-free and jam-free operation.
