Deep Groove Ball Bearings SKF 6013 -Z

SKF 6013-Z deep groove ball bearing with a 65 mm bore, 100 mm outer diameter and a single-sided sheet metal cover for industrial bearing applications requiring increased running accuracy.

The 6013 -Z deep groove ball bearing is a single-row radial ball bearing of the SKF Explorer design. It primarily accommodates radial loads and, thanks to its deep raceway geometry, is also suitable for accommodating moderate axial forces in both directions. The outer ring is cylindrical, without a flange or groove. SKF manufactures the component from standard rolling-bearing steel (100Cr6) with a guided steel sheet cage. On one side, a metal cover plate protects against coarse dirt particles, whilst the opposite side remains open to allow lubricant to enter.

Under what installation conditions is the 6013-Z deep groove ball bearing recommended?

This design, featuring a Z-cover on one side, is particularly suitable where one side of the housing is already sealed or where lubrication is supplied via an internal system. As the gap seal operates without contact, there are no friction losses caused by rubbing seal lips. The bearing generates little internal heat during operation and is suitable for bearing arrangements subject to combined radial and axial loads.

What are the distinctive features of the Z cover plate and tolerance class P6?

The Z-cover plate keeps solid foreign particles out without restricting the speed limits due to frictional heat. Manufacture to tolerance class P6 (equivalent to ABEC 3) means reduced dimensional and radial runout tolerances compared with standard tolerances. This supports precise guidance of rotating shafts and promotes smooth running in bearing seats with a diameter of 65 mm.
