GGB launches self-lubricating metallic bearing materials

GGB Bearing Technology, formerly Glacier Garlock Bearings, now offers two new metallic bearing materials. Its GGB-CSM series is made of solid material, and its bimetal GGB-CBM™ series features sliding layers sintered onto metallic backings. Both are self-lubricating for maintenance-free performance and provide high load capacity, a broad temperature range and corrosion resistance.

The GGB-CSM and GGB-CBM bearing materials are manufactured using a powder metallurgy process to produce a metallic matrix with homogeneously distributed solid lubricant (graphite,MoS2), which forms a lubricant film with the bearings’ motion. Potential applications include general mechanical engineering; steel plants; steel works and civil engineering; turbines (water, steam, gas); pumps and compressors; food & beverage industry, packaging and handling equipment; tyre mould and agricultural and construction machinery, among others.

The GGB-CSM series is based on a range of alloys consisting of bronze, iron and nickel, and includes materials that are wear-resistant, thermal relaxed and thermal stabilized. The GGB-CBM series is based on a range of bronze alloys, including lead-free offerings, with a choice of stainless, carbon, seawater-resistant steel and bronze backings.
