Grease is the word

Protecting bearings is critical to a motor's reliability and useful life.

That's why Baldor Electric Company, Fort Smith, Ark., is now using Exxon Polyrex EM polyurea grease to extend bearing life in its industrial electric motors from 1/50 to 1,500 hp.

In tests to 350°F, the new grease reportedly extends lubrication life for bearings by more than four times when compared to other polyurea greases. It is also more durable when subjected to mechanical shearing forces, says the company. A specially formulated additive system resists washout, rust, and corrosion, even when exposed to saltwater.
