A thrust bearing is a type of rotary bearing. They are like other bearings because they permit rotation between parts, but they are specifically designed to support a high axial load while rotating.

 

BENEFITS OF THRUST BEARINGS

  • Smoother rotation
  • Even weight distribution
  • Added stability to tall displays
  • Less bearing damage
  • Added strength during shipping
  • Less swaying and movement during rotation

WHAT ARE THRUST BEARINGS?

A thrust bearing is a type of rotary bearing. They are like other bearings because they permit rotation between parts, but they are specifically designed to support a high axial load while rotating.

HOW DOES IT WORK?

When just one lazy susan is used, all of the force is centered on one point (F1). This can damage the balls that allow for rotation. By adding a second bearing, the force is more evenly distributed (F1 and F2) and the bearing isn’t damaged by the imbalance of weight.

WHEN SHOULD IT BE USED?

Thrust bearings are essential when used in tall rotating applications, usually over 4 feet in height. They are also useful for short revolving components that have side-to-side movement. The taller the component, the less side-to-side force is needed to damage the bearing. When just one lazy susan bearing is used on a very tall rotating display, it can take very little horizontal force to pull them apart.
