Constant Force Adjustable Spacers

Temper® Load Rings are adjustable spacers that have unique properties: they are compressed at a constant force (permanent adjustment) and can spring back a small, constant value.

The spacers are designed to take up the stack of tolerances in an assembly, and they adjust bearings and the assembly to a specific setting.

Temper®’s proprietary design technology and manufacturing processes result in a highly consistent spacer – This means that you can have the confidence that every Temper® Load Ring will get you the results you expect.


Temper® Load Rings have been customized for a wide spectrum of consumer and industrial products, including:

  • Hydraulic pumps
  • Speed reducers
  • Electric motors
  • Farm tractors
  • Mining equipment
  • Lawn mowers
  • Conveyors
  • Irrigation units
  • Compressors
  • Boat motors
  • Sewing machines
  • Transmissions
  • Industrial Trucks


  • Eliminates Shimming
  • Optimize Bearing Life
  • Improve Accuracy
  • Simplify Bearing Installation

Because of its unique properties, you can:

  • Compress these adjustable spacers and they’ll spring back at a constant value, always giving you a known force
  • Transform assembly with controllable, repeatable procedures that save time and increase accuracy in bearing and assembly adjustments
  • Make selective shimming obsolete, meaning less assembly time, lower cost, and better precision
  • Simplify bearing installation and optimize bearing life

How it Works:

Temper® adjustable spacers have unique properties: they are compressed at constant force (permanent adjustment) and can spring back a small, constant value.
