LB 1, BS 1400


Soft bearing material with very good sliding and dry-running properties when there is a sporadic lack of lubricant and with water lubrication. Bearings with very high surface pressures in which high edge pressure can occur. Unsuitable for temperatures above 120 °C. Resistant to sulphuric acid. Very good machinability.

Very soft bearing material with excellent sliding and dry-running properties when there is a sporadic lack of lubricant and with water lubrication. But problematic with casting and rarely commercially available. For this reason usually replaced with Cu Sn7 Pb15-C.

Further Cast High Lead Bronzes available.
