Fretting Wear Test Machine

Overview

The Fretting Wear Test Machine from Falex meets the requirements of ASTM D4170 and includes integrated digital time control, the ability to operate at variable speeds, increased user safety, and a modern appearance. The tester uses two ball thrust bearings lubricated with the test grease and oscillated through an arc of 0.21 radians (12°) at a frequency of 30.0 Hz (1800 cpm) under a constant load of 2450 N (550 lbf) for 22 hours at room temperature. Fretting wear is determined by measuring the mass loss of the bearing races, and Falex Corporation is the listed sole source supplier of the required bearing specimens. Designed to perform the ASTM D4170 "Standard Test Method for Fretting Wear Protection by Lubricating Greases," the machine executes the specified oscillation, load, frequency, duration, and temperature conditions and determines fretting wear by measuring mass loss of the bearing races. Falex Corporation is available to supply the required bearing specimens and to support ASTM D4170 testing needs.
