Influence of load and rotation speed on life of PPS radial bearings under water lubricant conditions
Influence of load and rotation speed on life of PPS radial bearings under water lubricant condition was investigated.RCF tests were carried out at different loads and rotation speeds until 1.0x 106 cycles.After testing,rolling contact surfaces were observed by using a laser confocal microscope.From the observation,it was concluded that the life of PPS radial bearings under water lubricant condition was dominated by cracks and flaking failures.The failure of PPS bearings was caused by the flaking failures.The cracks were observed prior to the flaking failures.The life when flaking failure occur depends on the load and the rotation speed.
