How to use a standard grease gun

This video is a short demonstration on how to use a standard grease gun.

Four Ball Weld Test Demonstration

This video is a demonstration of a standard four ball weld test. The test is deemed to be complete when the ball bearings have welded together under the heat generated by friction. The first test is completed with a general purpose maintenance grease and the second test uses a bearing lubricant from our FOODLUBE range.
