Application:

The “High Temperature Grease Life Tester” use to evaluate the performance of lubricating greases in ball bearings operating under light loads at high speeds & elevated temperatures.

A grease lubricated SAE No. 204 size ball bearing is rotated at 10 000 rpm under light load at a specified elevated temperature. Tests are continued until failure or completion of a specified number of hours of running time.

This test method can be used to evaluate the ability of grease to provide adequate lubrication for extended periods of ball bearings operating under lights loads at high speeds and elevated temperatures.

Features:

Conforms to ASTM D 3336.
Digital Temperature Control .
Stainless Steel liner Heating Chamber.
Interactive touch screen HMI based interface.
Safety Interlocks of the Test Rig.
Touch screen HMI with inbuilt Data acquisition system.
Auto sequence through HMIC Controller.
