Axial Deep Groove Ball B. SKF 51203

The SKF 51203 single-direction axial deep groove ball bearing supports purely axial forces whilst maintaining compact dimensions of 17 × 35 × 12 mm.

The SKF 51203 axial deep groove ball bearing guides shafts in the axial direction and absorbs axial forces from a single direction. Manufactured from standard rolling-element bearing steel (100Cr6), this thrust bearing is characterised by its dimensional stability within a temperature range of -30 to +150 degrees. Due to its design, this bearing type is not capable of withstanding radial forces. With a 17 mm bore, 35 mm outer diameter and 12 mm height, the assembly fits precisely into space-saving installations in general mechanical engineering.

In which applications does the 51203 axial deep-groove ball bearing prove its worth?

Design engineers primarily use the 51203 axial deep-groove ball bearing where rotating components need to be supported on one side against axial thrust forces. Typical applications are found in industrial bearing arrangements with unidirectional axial loads in general mechanical engineering. As the design is that of a single-sided bearing, it specifically transfers axial forces into the housing. Separate radial bearings must take on additional radial guidance tasks to prevent the balls from running on the edges of the raceways and to avoid premature wear.

What is important when fitting the 51203 axial deep groove ball bearing?

During installation, the 51203 axial deep-groove ball bearing requires precisely perpendicular contact surfaces on the shaft and the housing shoulder. As this bearing is not angularly adjustable and is designed without a separate shim, misalignment errors lead to uneven load distribution across the rolling elements. The integrated sheet steel cage guides the rolling elements securely and retains its dimensional stability up to +150 degrees. Thanks to the standardised tolerance class P0/PN or ABEC 1, the component meets defined requirements for dimensional accuracy and concentricity.
