Axial Deep Groove Ball B. FAG 51204

The FAG 51204 axial deep-groove ball bearing, measuring 20x40x14 mm, is designed to accommodate unidirectional axial forces in mechanical engineering applications.

The 51204 axial deep-groove ball bearing is a separable rolling bearing designed to accommodate purely axial loads. The manufacturer, FAG, produces this model from 100Cr6 bearing steel and fits it with a sheet steel cage. The open design allows for the direct application of grease or lubricating oil. With a bore of 20 mm, an outside diameter of 40 mm and a height of 14 mm, the shaft and housing washers can be fitted separately.

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

The 51204 axial deep groove ball bearing is designed to provide axial support for shafts in one direction. Typical applications include bearing arrangements with unilateral axial loads in general machinery and fixture construction. As this design acts purely axially, no radial load must be applied to the bearing. Radial forces can be absorbed by a separate radial bearing on the same shaft. The combination of hardened raceways and guided steel balls enables the transmission of force under unidirectional axial pressure.

What should be borne in mind with the non-angle-adjustable design?

This single-direction rolling bearing has a flat housing flange and does not automatically compensate for misalignment between the shaft and the housing. Parallel bearing surfaces and an alignment at right angles to the axis of rotation are therefore essential for correct operation. The bearings are manufactured to tolerance class P0/PN (corresponding to ABEC 1) to meet standard precision requirements in the industrial sector. The permissible temperature range extends from –30 to +150 degrees Celsius, meaning the bearing is designed for the corresponding thermal conditions.
