Why Are Thrust Bearings Important?

Thrust Bearings/Axial Bearings Parts Diagram - Bearing Thrust Products

With Thrust Bearings or Axial Bearings, the force is parallel to the axis, which pushes against the bearing. The primary application is to separate a rotating surface from a non-rotating surface. Other examples would be supporting a rotary table or absorbing the thrust of a propeller.


How to Choose the Correct Thrust Bearings

  • Define the application: what is the design intended to do? Also include shaft dimensions or space dimensions for the thrust bearings.
  • Force or load against the bearing: What pressure or load is pressing on the thrust bearings?
  • 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 and decrease vibration and sliding friction. Preload must be considered and added to the application load when evaluating the total 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

A three-piece set, a Molded Ball Retainer, and two Thrust Washers.

  • The Nylon 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

Torque Transmission's Advantages

  • Lightweight nylon retainer
  • Natural lubricity
  • Corrosion-resistant
  • Extremely quiet operation.
  • Economical, longest-lasting
