Axial Deep Groove Ball B. FAG 51320

The FAG 51320 axial deep-groove ball bearing accommodates purely axial forces and has an outside diameter of 170 mm and a width of 55 mm.

This single-direction axial deep-groove ball bearing 51320 from FAG supports axial forces in one direction. As a multi-piece bearing, the unit consists of separate bearing discs and a guided ball set. Manufactured from standard rolling-bearing steel, it ensures high dimensional stability of the raceways. Thanks to its separable design, you can fit the shaft disc and the housing disc one after the other, which facilitates installation in machine designs.

What is the 51320 axial deep-groove ball bearing suitable for in operation?

Axial deep-groove ball bearings of this design are suitable for bearing arrangements where high axial thrusts occur. As their design means they cannot accommodate radial loads, designers often combine this bearing with separate radial bearings. Typical applications include vertical shaft mountings and general mechanical engineering equipment. The flat housing flange requires a contact surface machined at right angles to the axis of rotation to prevent misalignment and to ensure even load distribution across the entire set of rolling elements.

What characteristics does the sheet steel cage offer under fluctuating temperatures?

In this design, a dimensionally stable sheet steel cage guides the rolling elements along their circular path. The component withstands thermal stresses in the range from –30 to +150°C. The steel cage withstands common lubricating oils and rolling bearing greases without material fatigue. When designing the assembly, you should ensure a sufficient minimum load. A permanent axial preload prevents harmful slippage between the balls and the raceways, which helps to extend the bearing’s service life.
