STD-RCF 4 Rolling Contact Fatigue & Bearing Friction Rig may be used for both endurance testing and precision bearing frictional loss measurement. Two test assemblies are available:
• combined radial and axial loading
• bi-directional axial loading
Load is applied by means of servo controlled pneumatic bellows with force transducer feedback.
An in-line torque transducer is provided for friction measurement, with a maximum permissible speed of 10.000 rpm.
Bearing outer race temperatures are measured with thermocouples and a vibration sensor with adjustable level trigger circuit is provided for stopping the machine at the on-set of rolling contact fatigue.
An integral lubricant service module is fitted as standard incorporating a sump tank with immersion heater, delivery pump, scavenge pump, oil to water heat exchangers for cooling and change-over filters.
