ASTM D4693 Low Temperature Torque Tester For Grease Lubricated Wheel Bearings

Introduction

This Low Temperature Torque Tester is suitable for measuring the running performance of the grease in the specially manufactured, spring-loaded automobile wheel bearing assembly under low temperature conditions. The test principle is to fill the grease sample into a specially manufactured automobile wheel bearing assembly.The assembly is heated first, and then cold soaked at -40°C. In addition, other test temperatures can be set according to the requirements of the grease specifications. The spindle is rotated of 1r/min, and the torque value to prevent rotation of the hub is measured at 60 s.
