A pump draws heated water from the tank, through a filter and sprays it, via a 1mm capillary, onto the face of the bearing at a flow rate of 300ml/ min, The temperature of the water is digitally controlled in the range of water is digitally controlled in the range of ambient to 800C. The water containing washed out grease is collected in the tank, filtered, and recycled. A drain tap allows the tank to be emptied at the end of a test.
