Axial Deep Groove Ball B. FAG 51203

The FAG 51203 axial deep-groove ball bearing accommodates unidirectional axial forces and, thanks to its compact dimensions of 17 × 35 × 12 mm, is suitable for space-saving designs.

The FAG 51203 axial deep-groove ball bearing is designed as a separable rolling bearing for supporting purely axial loads. It supports shafts in an axial direction but must not be subjected to radial forces. Manufactured from standard roller bearing steel (100Cr6), the bearing offers high dimensional stability for industrial assemblies. The open design allows for a flexible choice of lubricant and facilitates the step-by-step assembly of the shaft ring, housing ring and rolling element set.

What is the 51203 axial deep-groove ball bearing suitable for?

This rolling bearing is primarily used in bearing arrangements where axial forces along the shaft axis need to be absorbed. Typical applications are found in general mechanical engineering for shaft guides with a clearly defined axial load direction. Thanks to the guided sheet steel cage, the ball set remains evenly distributed around the circumference even under continuous load. The permissible temperature range extends from -30 to +150 degrees, making the component suitable for a variety of thermal environmental conditions in industrial plants.

What is important to bear in mind when installing this single-acting bearing?

During assembly, the precise alignment of the mating parts is essential. As this design is not angle-adjustable, the contact surfaces on the shaft and housing must be machined at right angles to the axis of rotation. The bearing is supplied without shims, which is why flat, parallel contact surfaces are essential for uniform force transmission. Manufacture to tolerance class P0/PN (corresponding to ABEC 1) defines the standardised dimensional tolerances of the individual components. Furthermore, care must be taken to ensure the correct pairing of the shaft washer and housing washer to prevent malfunctions.
