一. Main usesSapphire bearing fatigue testing machine is used in the form of sliding friction, under the specified test conditions to assess the performance of sapphire bearing, etc., to determine its PV value and reasonable matching gap, lubricating medium, friction mate material, surface roughness, hardness, etc. It can be tested under various conditions of oil-free lubrication, drip-oil lubrication and changing load, speed, time, friction material, surface roughness, hardness and other parameters. Can be used to measure bearing temperature rise, friction coefficient, wear, PV value.
