51100 Ball Thrust Bearings Series

The 51100 Ball Thrust Bearings are a type of rotary ball bearing designed to support high axial loads (parallel to the shaft). Here are some key features:

  • Single-direction axial load support: They can accommodate axial loads in one direction.

  • Separable components: The bearings consist of two washers (raceways) with grooved surfaces, caged rolling balls, and a steel ball retainer.

  • High-speed capability: These bearings can operate at higher speeds compared to roller thrust bearings.

  • Oil lubrication: Higher speed applications require oil lubrication for smooth operation.

51100 Ball Thrust Bearings 
A ball thrust bearing is a particular type of rotary ball bearing. Like other ball bearings, they permit rotation between parts, but they are designed to support a high axial load, while doing this (parallel to the shaft). Higher speed applications require oil lubrication. Generally, they are composed of two washers (raceways) which may be grooved the rolling balls elements which are typically caged. As opposed to roller thrust bearings, ball thrust bearings can generally operate at higher speeds but at lower loads.
