High Temperature Grease Tester -D3336

High Temperature Grease Tester -D3336


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.
