Deep Groove Ball Bearings FAG 6011 -Z

The FAG 6011-Z deep groove ball bearing, with dimensions of 55 × 90 × 18 mm, is designed to accommodate radial shaft loads whilst maintaining a compact design.

The 6011-Z deep groove ball bearing is a single-row radial ball bearing manufactured to metric standard dimensions from through-hardened 100Cr6 rolling-bearing steel. It primarily absorbs radial forces, but also supports shafts under moderate axial forces in both directions. With a 55 mm bore, 90 mm outer diameter and 18 mm width, this bearing covers common shaft diameters in mechanical engineering. The design is from FAG Rolling Bearings and features a standard radial clearance. A sheet steel cage keeps the rolling elements spaced apart and aids load distribution during operation.

What is the 6011-Z deep groove ball bearing suitable for in operation?

This single-row deep-groove ball bearing is primarily used in rotating shaft arrangements subject to radial forces and moderate axial forces. The 55 mm cylindrical bore allows for direct mounting on suitable shaft seats. In housing designs where lubricating oil or grease is retained inside the housing, the unit can be integrated as a fixed or floating bearing.

What is the function of the single-sided cover plate on the 6011 -Z type?

The designation -Z refers to a non-contacting cover plate made of profiled sheet metal on one side of the bearing. This metal cover protects the interior of the bearing from coarse particles without generating any additional frictional torque or unwanted heat build-up. The opposite side remains open, allowing housing lubricant to reach the raceways. Before installation, it must be checked whether the single-sided cover is sufficient for the respective sealing concept.
