Deep Groove Ball Bearings FAG 6015 -Z

The FAG 6015-Z single-row deep-groove ball bearing, with a 75 mm bore and a cover plate on one side, offers reliable protection against dirt particles.

The 6015-Z deep-groove ball bearing provides designers and maintenance engineers with a versatile rolling bearing for combined loads. This FAG component primarily absorbs radial forces, but also supports axial forces in both directions thanks to the raceway geometry. Manufactured from standard rolling-bearing steel 100Cr6, the rolling elements and rings offer high strength. With dimensions of 75 mm inner diameter, 115 mm outer diameter and 20 mm width, the bearing complies with standard ISO specifications for tolerance class P0.

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

The bearing is primarily used in rotating shaft assemblies where one side of the housing is open, whilst the other side needs to be protected. Typical applications include rotating shafts and mechanical drive units subjected to combined loads. Thanks to its robust sheet steel cage, the roller bearing guides the balls with low vibration even at varying speeds. Furthermore, the bearing is designed for operating temperatures ranging from –30 to +150 degrees.

What are the advantages of the single-sided Z-cover when selecting a bearing?

The suffix ‘Z’ denotes a non-contacting sheet metal cover on one side of the bearing. This cover keeps coarse dirt and falling particles out of the bearing interior, but does not cause any additional friction compared with sliding seals. The open side on the opposite side also allows for targeted relubrication via the machine housing or an oil circuit. As there is normal radial bearing clearance, this design is suitable for standard fit conditions without extreme thermal expansion of the shaft or housing.
