Lever Four Ball Friction Testing Machine 200N Rubbing Wear Instrument
Lever Four-ball Friction Testing Machine Rubbing Wear Instrument
Product Introduction
The 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 sintering load PD, and the comprehensive wear value ZMZ, etc. three indicators.
