Bup Fatigue Strength Test Machine

The MAKRA BUP Alloy Wheel Fatigue Strength Test Machine is used for fatigue tests on wheels. Through the application of a centrifugal force applied by a rotating counterweight, the BUP test machine duplicates the forces that are applied to the front wheel of an automobile during hard right or left hand turns at high speed.


  • Octagonal design for easier access all around the machine.
  • T-slot guided clamping jaws simplify clamping and unclamping of the wheels.
  • Clamping table size and shape allows for testing of wheels with nominal diameter from 14” to a maximum 50” (with a special clamping lever) and width from 5” to 26”
