Introducing the Enduralube A Series Bearings: The World's Most Reliable Bronze Bearing

Roseville, MI — National Bronze Mfg. Co., a leading manufacturer of bronze bushings, bearings, and machined components, is pleased to announce the addition of “A Series” Enduralube Bearings to their vast product lines of copper alloy based products.

Enduralube self-lubricating are known as some of the most reliable bronze bearings in the market.  This reliability comes from the combination of the cast bronze base metal and the proprietary solid lubricant plugs.  This combination gives our customers a maintenance free bearing able to withstand even the most extreme environments.

The Enduralube “A” Series bearings can be utilized where heavier than normal loads are required as well as in environments normally corrosive to bronze. They key to the load bearing and anti-corrosive properties of the “A” series is the use of an aluminum bronze alloy as the base metal.  When exposed to corrosive environments that aluminum bronze creates an aluminum oxide coating that further protects the metal.
