Deep Groove Ball Bearings SKF 6019 -Z

The SKF 6019-Z deep groove ball bearing, measuring 95x145x24 mm, provides precise guidance for combined loads with single-side protection.

The 6019-Z deep groove ball bearing is a single-row rolling bearing in the SKF Explorer series for shaft diameters of 95 mm. Manufactured from standard rolling-element bearing steel (100Cr6) and guided by a robust sheet steel cage, this design primarily accommodates radial loads as well as moderate axial forces. The single-sided sheet metal cover protects the interior from coarse contaminants, whilst the open opposite side allows for direct relubrication via the lubrication circuit if required.

In which applications is the 6019-Z deep groove ball bearing used?

This size is used in bearing arrangements that combine radial forces with moderate axial forces. As the bearing is designed for a temperature range of -20 to +150 degrees, it is suitable for demanding thermal operating conditions. It is typically used in installations where one side of the housing is already sealed, or where lubricant from the interior is intended to reach the exposed rolling elements unimpeded.

What are the advantages of the Z-cover and the P6 tolerance?

The metallic Z-cover acts as a non-contact gap seal, meaning that no additional frictional resistance is generated at the sealing surfaces. Furthermore, the bearing is characterised by increased dimensional accuracy to tolerance class P6 with normal running accuracy PN. This ensures a precise fit on the shaft and housing. In conjunction with the standard radial bearing clearance, the component is suitable for standard operating conditions without extreme thermal expansion.
