Why a Thrust Bearing is Important

thrust-bearing-exploded-blueWith a Thrust Bearing or Axial Bearing, the force is parallel to the axis, which pushes against the bearing. There are many thrust bearing applications, but the primary application is to separate a rotating surface from a non-rotating surface. Some examples would be: supporting a rotary table, absorbing the thrust of a boat's or airplane's propeller, and neutralizing friction.


How to choose the correct thrust bearing

  • Define the application: what is the design intended to do? This includes shaft dimensions or space dimensions for the thrust bearing.
  • Force or load against the bearing: What is the total pressure or load pressing on the thrust bearing?
  • Thrust bearing preload: Bearing preload is a predetermined load applied to a bearing and is separate from application loads. Preload is a design consideration to increase rigidity, decrease vibration, and sliding friction. When evaluating the total load, preload needs to be considered and added to the application load.
  • RPM of the application?
  • Hours of operation or cycle time?
  • Operating environment, does the operating environment require special consideration?

A Torque Transmission Thrust Bearing

Our Thrust Bearing is a three-piece set, a Molded Ball Retainer, and two Thrust Washers.

  • The Ball Retainer is Injected molded using heat stabilized nylon 6/6
  • The balls are carbon or stainless steel, hardened to Rc 60 and finished to Grade 100, 0.0001-inch tolerance.
  • The thrust washers are stamped to a tight ID and OD tolerance heat treated and finished to a 10 micro inch finish.

         The Carbon Steel Washer is CR 1075 hardened to Rc 59-61

         The Stainless Steel Thrust Washer is CR 410 Stainless hardened to Rc 38-42


The Advantages

  • Lightweight nylon retainer

  • Natural lubricity

  • Corrosion-resistant

  • Extremely quiet operation.

  • Economical, longest-lasting

We manufacture high quality thrust bearings in a wide range of sizes and materials – inch or metric, Carbon or stainless steel.
