Axial Deep Groove Ball B. FAG 52218

The FAG 52218 double-sided axial deep-groove ball bearing supports shafts with a 75 mm bore and an outer diameter of 135 mm against axial forces acting in both directions.

The 52218 axial deep-groove ball bearing absorbs axial forces in both directions and supports shafts on both sides. FAG manufactures this rolling bearing from standard bearing steel (100Cr6) with a sheet steel cage. With a bore of 75 mm, an outside diameter of 135 mm and a width of 62 mm, it supports components under purely axial loads. Typical applications are found in conventional mechanical engineering for shaft guides subject to axial loads on both sides. The bearing is manufactured to tolerance class P0/PN or ABEC 1 for normal running accuracy.

In which designs does the 52218 axial deep-groove ball bearing prove its worth?

The bearing is designed for applications that need to specifically accommodate axial forces from both directions. As axial deep-groove ball bearings accommodate purely axial loads, the shaft requires additional radial support. Thanks to its temperature range of -30 to +150 degrees, the rolling bearing retains its dimensional stability even when subjected to operational heat.

What characterises the double-acting design without a washer?

The 52218 axial deep-groove ball bearing is a double-acting variant comprising a shaft disc, two housing discs and two ball rings. The bearing is not angularly adjustable and is designed without shims. The mating surfaces on the shaft and housing must therefore be machined exactly at right angles to the axis of rotation in order to counteract edge stresses. Lubricants designed for an operating temperature range of -30 to +150 degrees are used.
