Schaeffer's Ultra Supreme Grease is extreme pressure, para-synthetic, aluminum grease that extends bearing life. Ultra Supreme Grease quickly lubricates metal surfaces, offering solid, durable protection that lasts longer than conventional greases. Adverse working conditions are no problem for this extra tacky grease. Ultra Supreme Grease will not break down during periods of tremendous pressure, increased heat and high shock loads. Fortified with Moly, Ultra Supreme Grease significantly reduces friction, which reduces wear and contact area temperature. Ultra Supreme Grease forms a seal that resists water, preventing grease from washing out. Ultra Supreme Grease is designed for heavy duty equipment, industrial equipment, pin and bushing and fifth wheel applications. Not recommended for use in passenger car automotive wheel bearing and electric motor bearing.
