For more than 60 years, ALC Bearings has developed a range of plain bearings with standard diameters. The bearings possess a bush mounted on a ball and are well-adapted to support gear drives of rotating mills and kilns used in extractive industries. They are also suitable for rotating machines used in chemical and sugar process industries.

 

• The major benefit of a ball bearing with white metal coating is the load restoration capacity for low rotation speeds.

• With an adequate lubrication of the bearings, a very low friction coefficient is reached. ALC bearings are designed to function normally in a hydrodynamic regime with a sufficient safety margin to keep an adequate oil film.

• Operational safety: as a low melting point alloy, the white metal melts in case of major problems. ALC plain bearings will not suddenly break, which would thus avoid more important damages – particularly on the shaft seat – or an unexpected and very expensive machine stop. 

• The alloy used for ALC bearings is composed of lead. A lead alloy is more fragile than a tin one, but more adapted to low rotation speeds.
