Precision - Shell 4 Ball Extreme Pressure Test

Evaluates the extreme pressure characteristics of lubricants by load scar curve and weld point. A series of 10 seconds runs are made at increasing loads until 4 steel balls are friction welded together. The scarring and weld point are then measured to establish the final results. The comparison graph speaks for itself!

SKF TMG/ROF Speed and Temperature Test

SKF one of the worlds leading bearing manufacturers, developed it's own test apparatus to ensure greases which promise temperature and high speed performance actually offer what is promised. In simple terms, the longer the running time, the better the grease!
