KN-1478 Low-Temperature Torque Tester

Overview

  KN-1478 Low-Temperature Torque Tester conforms to ASTM D1478 Standard Test Method for Low-Temperature Torque of Ball Bearing Grease. This test method was developed using greases having very low torque characteristics at -54℃. Specifications for greases of this type commonly require testing at this temperature. Specifications for greases of other types can require testing at temperatures from -73℃ to -18℃.

  This test method has proved helpful in the selection of greases for low-powered mechanisms, such as instrument bearings used in aerospace applications. The suitability of this test method for other applications requiring different greases, speeds, and temperatures should be determined on an individual basis.
