Axial Deep Groove Ball B. FAG 51202

The 51202 axial deep-groove ball bearing from FAG Wälzlager is designed for shafts with a 15 mm bore and accommodates single-direction axial forces.

The 51202 axial deep-groove ball bearing accommodates axial loads exclusively and supports shafts in one direction. The unit consists of a shaft ring, a housing ring and a guided ball set with a sheet steel cage. Manufactured from standard rolling bearing steel 100Cr6, this design covers a temperature range from -30 to +150 degrees. Designs incorporating this rolling bearing require separate support for any radial forces that may occur, as the ball raceways are aligned purely axially.

What is the 51202 axial deep-groove ball bearing suitable for?

This roller bearing is used in designs where purely axial forces in one direction need to be absorbed. This design supports shafts in the axial direction and is designed for operating environments without misalignment. As this design is not angularly adjustable, it is mounted in housings with aligned contact surfaces. Without additional shims, the bearing rests directly against the mating surfaces.

What should be borne in mind regarding the single-direction load?

The two discs of this bearing are dimensionally different for functional reasons: the shaft disc has a ground bore with a diameter of 15 mm for a tight fit on the shaft, whilst the housing disc has a slightly larger bore to prevent contact. During assembly, the installation direction determines how force is transmitted via the sheet steel cage and the rolling elements. Radial loads must not be applied to the assembly.
