Typical Uses

This material has proved its value in sliding bearings and withstands moderate bearing pressures very well with adequate lubrication. Especially in the engineering industry, can be manufactured economically from this material. The unique composition results in good wear and running properties, as well as good relief of end pressures and excessive stresses from inadequate or occasional interruptions of lubrication. The surface finish and hardness requirements for the opposing material are not so great as with hightin bronzes. With good lubrication, unhardened shafts can be used. The alloy has good sliding and emergency running properties
