Axial Deep Groove Ball B. FAG 52309

The FAG 52309 double-acting axial deep-groove ball bearing, measuring 35x85x52 mm, supports axial forces acting from both directions in industrial machinery.

The FAG 52309 axial deep-groove ball bearing is an open rolling bearing designed for applications subject to purely axial loads from two directions. With key dimensions of a 35 mm bore diameter, an 85 mm outer diameter and a 52 mm height, the component supports rotating shafts axially in both directions. Manufactured from standard rolling bearing steel 100Cr6, the component retains its dimensional stability at operating temperatures ranging from –30 to +150 degrees. A dimensionally stable sheet steel cage guides the rolling elements evenly along the raceways.

What is the 52309 double-acting axial deep groove ball bearing suitable for?

This rolling bearing absorbs axial forces from alternating directions and provides axial support for machine components. As axial deep-groove ball bearings cannot absorb radial forces, designers always combine this bearing type with separate radial bearings to accommodate radial loads. Typical applications include industrial shaft mountings where axial thrust forces act alternately in both directions on the bearing assembly.

What should be taken into account when aligning the 52309 axial deep groove ball bearing?

As this design is not angularly adjustable, the component requires flat and precisely perpendicular contact surfaces on the housing and shaft. Even slight misalignments generate edge stresses, which place uneven loads on the raceways and increase wear. This bearing complies with tolerance class P0/PN or ABEC 1 and is fitted without shims. Clean contact surfaces and lubrication appropriate to the application contribute to low-friction operation.
