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 and 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 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.
Bearings made of the GGB-CSM and GGB-CBM materials are available by special order to customer-supplied designs and drawings.
GGB Bearing Technology has also developed a patented design for the industry’s first dual-component, double-flanged solid polymer bearings. Called FLASH-CLICK, the new bearings feature a special geometry for easy manual or automated installation without the need for pilot or assembly tools. Their two-piece construction facilitates installation from different directions, and by allowing bearing housing tolerances to be reduced, they reduce total system costs.
The bearings are available in all nine of GGB’s EP series of lightweight, corrosion-resistant solid polymer materials, which provide low friction, long wear and noiseless operation. These properties make them suitable for replacing more costly bearings in many applications, such as automotive seats and convertible tops.
Bearings can be supplied in virtually unlimited custom dimensions, pending project-related feasibility checks. They also can be supplied in multiple sections for creating longer bearings.
