The Problem

During greasing, the grease forces the primary piston (no.46) movement by way of the needle valve (no.64) and blocks off the relief channel, allowing fresh grease to enter the bearing cavity.

Most bearing failures are due to over/under greasing, excess grease heat generation, or seals being compromised and contamination!

The cost of collateral damage, downtime, lost production can be enormous!

If we reduce the friction by 10% in all rolling bearings in use today, we would save energy equivalent to the combined output of 18 large nuclear generating stations! Over greased bearings cause heat generation and added friction within the bearing.

Electric mini-lubers/constant positive feed systems are not the answer for rolling element bearings – feed only no pressure vent, or capacity for lube analysis or environmental issues.
