Deep Groove Ball Bearings FAG 6222 -2Z

The FAG 6222 -2Z deep-groove ball bearing, with a bore of 110 mm, an outer diameter of 200 mm and cover plates on both sides, is designed primarily to accommodate radial loads.

The FAG 6222 -2Z deep groove ball bearing is a single-row radial ball bearing for machine mountings with a shaft diameter of 110 mm. Manufactured from through-hardened standard roller bearing steel (100Cr6), this unit primarily withstands radial loads as well as moderate axial forces in both directions. This design features a cylindrical outer ring without a groove or flange. The non-contact covers on both sides protect the interior of the bearing from coarse dirt particles without generating additional frictional heat during operation.

In which applications is the FAG 6222-2Z deep groove ball bearing used?

This radial deep-groove ball bearing is designed for mounting shafts with a diameter of 110 mm at constant speeds. Typical applications include industrial drives, gearboxes and rotating machine components. As the rolling elements and rings are manufactured from conventional standard rolling-bearing steel, the component offers dimensional stability under purely radial as well as combined load profiles in enclosed machine compartments.

What is the function of the 2Z cover plates and the standard radial bearing clearance?

The designation ‘2Z’ indicates the use of two profiled sheet metal cover plates, which form a narrow gap with the inner ring shoulder. This non-contact sealing variant prevents power losses due to friction and protects the internal area, including the steel cage, from the ingress of foreign particles. The standard radial bearing clearance (Class CN) ensures, provided the fit is correct and operating temperatures are moderate (between -30 and +120 degrees), a balanced combination of smooth running and concentricity in accordance with tolerance class P0.
