CuSn12 and CuSn12Pb Bronze Bearing Alloys
CuSn12 (CC483K/CB483K) is a bronze alloy with a high tin content that offers superior mechanical properties compared to Rg7, a common bronze alloy. This alloy, by incorporating more tin and reducing the use of zinc and lead, is harder and tougher. It demonstrates good corrosion resistance, especially in marine environments.

Solid Lubricant
Solid Lubricants and Start-up Films
The inserts are placed overlapping in the sliding direction. The lubricating film degrades over time but is replaced by the lubrication provided by the inserts. Once the bearing is fully machined, a 20-micron film-like solid lubricant insert composition can be applied. This thin film alleviates the critical start-up process (stick-slip).
