Abstract
A universal friction tester for testing tribological properties of materials comprises a frame with a carriage sliding in vertical guides and supporting a slide moveable in a horizontal direction. The slide supports a stationary upper specimen, which engages a moveable lower specimen, located in a replaceable module attachable to a base plate of the frame. The modules may be of a rotary, reciprocating, a block-on-ring, or any other type, required for different test conditions. Testing can also be carried out with heating or with the supply of oil in the zone of contact between the specimens.
