Separation of stored grease
Separation of stored grease
(OP)
A collegue has flagged a potential problem. We have a grease packed gearbox which will have a shelf live of over five years - if it is not req'd as a spare! Does anyone know of an instance where the components of the grease have separated into oil plus the rest?

Some customers will scream if you are dripping out of the gearbox. We had a gearmotor that went into a printer, and we were obliged to make changes in the lube system. The grease was PAO NLGI 2, and the bearing was changed to a polymer type.

the amount of leakage is partly depending on the thickener agent of the grease but the viscosity of the fluid incorporated is of much larger importance. the thinner the fluid used, the more leakprone a grease will be.
