Low-Temperature Torque Tester

Low-Temperature Torque Tester TT-1478

Low-Temperature Torque Tester TT-1478 complies with ASTM D1478 Standard Test Method for Low-Temperature Torque of Ball Bearing Grease.

This method was devised using greases exhibiting very low torque characteristics at -54°C. It's common for greases of this kind to necessitate testing at such temperatures. For other grease types, testing may be required at temperatures ranging from -73°C to -18°C.

This testing approach has proven valuable in selecting greases for low-powered mechanisms, like instrument bearings in aerospace applications. However, the suitability of this method for other applications with varying greases, speeds, and temperatures should be assessed on a case-by-case basis.

1. Test bearing includes eight 7.9mm balls, separated by a two-piece pressed steel cage, with a standard radial clearance of 0.008 to 0.018mm.

2. Microcomputer temperature controller, with a range from ambient to -70°C.

3. Pt100 temperature sensor, accurate to 0.1°C.

4. Imported compound compressor for low noise operation.

5. Driving motor utilizes a high-speed ratio of 1740/1 to maintain stable rotating speed.

6. Low-temperature tank features dedicated insulating material, ensuring the ambient environment does not affect the inner temperature.

7. Digital display indicates the pull-in torque and running torque.

8. Brass grease cup strictly conforms to standard requirements.

9. Digital display for working time, equipped with alarm function.

10. Stainless steel air bath.
