The Plain Bearing PV Friction Testing Machine is designed to evaluate the friction and wear properties of engineering plastics, powder metallurgy, alloy bearings, and other materials under sliding friction conditions. By simulating different loads, speeds, friction materials, surface roughness, hardness, and lubrication conditions, the system determines the PV value of the material (the product of pressure and velocity), which represents the load-bearing capacity of plain bearings.

This instrument is critical for material R&D, optimal bearing design, quality control, and development of new materials.

Applications

The testing machine is widely used in:

Material Performance Evaluation

Simulates real working conditions to measure friction coefficient, wear resistance, and PV value.
