Spin Test: Identifying Noise or Grinding. Lift your vehicle so the wheel is off the ground and can spin freely; Spin the wheel, in either direction, and listen for a grinding or howling noise; If you hear a loud grinding or howling noise, that increases with the speed of the wheel, you have a failed bearing that needs to be replaced

Bond reported that wear rates during grinding became extreme as the pH of the liquid dropped below 5.5. Ellis did extensive tests on the effect of pH and atmosphere on steel balls while wet grinding sand in small 0.3- and 1-m-diam mills. Norman and Loeb extended the work to include the grinding of molybdenum ore in 3-m-diam mills.

The ball screw drive was identi-fied as mainly responsible for the axis positioning accuracy. Increasing wear of the ball screw leads to a decrease of the ball screw pre-load. Therefore a condi-tion monitoring strategy for the detection of loss of this pre-load was chosen [14]. The implemented methods for measuring the wear of the ball screw ...
