Item: Lever-type Friction Wear Testing Machine(Four Balls Method)
Model: PT-HK-12583
Overview
Four ball wear testers is used to test the Wear Preventive (WP) and Extreme Pressure (EP) characteristics of greases and lubricating oils in sliding steel-on-steel applications. It conforms to the ASTM D2783, ASTM D2266 and ASTM D4172Standard Test Method for Wear Preventive Characteristics of Lubricating Fluid (Four-Ball Method). The tester adopts sliding friction, under the high point contact pressure, to evaluate the carrying capacity of the lubricant. It includes the maximum nonseizure load PB, sintering load PD and composite wear value ZMZ three items indexes. The tested is also used for the long-time abrasion resistance tests, to measure the friction coefficient.
