Axial Deep Groove Ball B. SKF 51204

The SKF 51204 axial deep-groove ball bearing accommodates single-direction axial loads in mechanical engineering applications, with compact dimensions of 20 × 40 × 14 mm.

The 51204 axial deep groove ball bearing is a single-direction rolling bearing designed to support pure axial forces in one direction. This SKF model consists of a shaft ring, a housing ring and a guided ball and cage assembly. With dimensions of a 20 mm bore, 40 mm outside diameter and 14 mm height, the bearing guides shafts with axial precision. As it is manufactured from standard rolling bearing steel 100Cr6, the component is suitable for demanding industrial applications within a temperature range of -30 to +150 degrees Celsius.

What is the 51204 axial deep-groove ball bearing suitable for?

This rolling bearing supports rotating shafts against axial forces acting from one side. Due to its design, the component must not bear radial loads. Typical applications are found in assemblies where clearly directed longitudinal forces occur and must be reliably supported. As the bearing is not angularly adjustable, installation requires precisely perpendicular contact surfaces on the shaft and housing. The integrated sheet steel cage keeps the rolling elements neatly separated from one another and ensures smooth running with uniform rotational movement.

What are the special features of the single-direction bearing 51204?

The scope of supply includes the single-direction bearing without a washer. With standard tolerance P0 or ABEC 1, the component meets the usual precision requirements of general mechanical engineering. Before installation, check the alignment of the connecting structure, as angular misalignment can lead to edge loading and premature wear. You should also ensure that the lubrication is suitable for the temperature range of -30 to +150 degrees and that an external seal is fitted, as the bearing is designed as an open assembly.
