MPV-20B screen display PV friction testing machine
MPV-20B screen display PV friction tester adopts the form of sliding friction, which can be tested under various conditions such as drip lubrication and no lubrication and changing parameters such as load, speed, time, friction mating material, surface roughness and hardness. . It is mainly used to evaluate the friction and wear properties of bearing materials such as plastics, powder metallurgy and alloys, and to determine the reasonable matching clearance and PV value of bearings . It can also be used to measure bearing temperature rise, friction coefficient, and wear.
The test machine can meet the requirements of the standard GB/T 7948-1987 plastic bearing limit period PV test method.
