FAG 51103 Thrust Ball Bearing

Description

This is a FAG 51103 single direction thrust ball bearing, a precision component engineered for reliability. Made in Germany, it is designed to handle axial loads with high accuracy. The bearing is separable, meaning the shaft washer, housing washer, and ball and cage assembly can be mounted independently, simplifying installation and maintenance. This item is new old stock (NOS), unused and fully functional, but may show signs of long-term storage on its packaging.

FAQ

What are the main applications for a single direction thrust bearing like the FAG 51103?

It is primarily used in applications that must support heavy axial loads in one direction, such as vertical shaft supports, machine tool tables, and screw jacks. It ensures smooth rotation under thrust.

What is the significance of the separable design of this bearing?

The separable design allows for easier and more convenient mounting. The shaft and housing washers can be installed independently of the ball and cage assembly, which simplifies the assembly process, especially in tight spaces.

Can the FAG 51103 handle radial loads?

No, this bearing is designed exclusively for axial (thrust) loads. Applying radial loads can cause premature failure and damage to the bearing and the machinery.
