FAG 51210 Thrust Ball Bearing 50x78x22

High-Capacity Thrust Bearing for Axial Loads

The FAG 51210 is a single-direction thrust ball bearing, optimised for demanding axial load applications. With an inner diameter of 50 mm, outer diameter of 78 mm and width of 22 mm, this unit meets the DIN 711 / ISO 104 standard. Manufactured from hardened bearing steel and equipped with a sheet-steel cage, it offers high durability, precise rotation and low friction even under elevated loads and speeds. The separable design (shaft washer, housing washer and ball-cage assembly) enables efficient installation and maintenance, making it ideal for industrial systems where serviceability matters.

Technical Features & Industrial Applications

FAQ

1. What load direction does the FAG 51210 support?
It supports axial loads in one direction (single-direction thrust bearing) and is not intended for radial load carrying.

2. What are the external dimensions of this bearing?
The dimensions are 50 mm (inner diameter) x 78 mm (outer diameter) x 22 mm (width).

3. Can this bearing operate at high rotational speeds?
Yes — while thrust bearings are primarily designed for axial loads, the FAG 51210 offers robust performance and good speed capability for demanding industrial use.

4. Is the FAG 51210 suitable for use in heavy-duty gear reducers and industrial drives?
Absolutely — its design and load ratings make it ideal for heavy-duty industrial applications where axial loads are prominent.

5. How should this bearing be maintained?
The separable design allows individual installation of components. It is recommended to ensure correct alignment, use appropriate lubrication, and monitor axial clearance to ensure maximum lifespan.
