Digital Display Lever Type Four-ball Friction Tester Digital Readout Meter
1.Product Introduction
The LR-MRS Lever Four-ball Friction Testing Machine is a cost-effective laboratory evaluation equipment developed by our company to meet the needs of lubricant research and production users. This testing machine adopts the sliding friction mode and, under extremely high point contact pressure conditions, evaluates the bearing capacity of lubricants, including the maximum no-stall load PB, the sintered load PD, and the comprehensive wear value ZMZ, etc. three indicators.
