Hi.
For greases to work, as you're aware, there are a number of rheological requirements to be met.
Parameters include: adherence, retention of properties under both shear & temperature, and some degree of fluidity. (More viscous materials risk more "work", especially in start-up.)
What kind of grease are you using? Generally, heavier duty greases integrate bases like ISO 460 (SAE 140). Thickeners can include: soaps of lithium, sodium, calcium (hydrated and anhydrous, polyurea and clay.
For more information, I'd look to The National Lubricating Grease Institute (NLGI): http://www.nlgi.com.
Good luck!
