High Speed Roller Fatigue Test System

This Tier 1 supplier required a laboratory-grade test system to evaluate the performance of various bearing designs and configurations.

The test system utilizes a 8,000 RPM servomotor that carries a spindle and chuck assembly to drive the DUT. A 2300 PSI hydraulic power pack equipped with an electronic pressure control system, provides hydraulic pressure to three linear slides.

The linear slides carry precision rollers that apply a lateral force - 120 degrees apart - to the DUT. Application force is calculated, monitored and controlled by fluid pressure measurement and cylinder cross section area.

The system includes bearing lubrication, misting abatement, and front-end controls utilizing National Instruments hardware and LabView.
