Plain bearings specialist offers new metallic bearing materials
13 April 2013
GGB Bearing Technology is now offering two new metallic bearing materials. Its GGB-CSM series is made of solid material, and its bimetal GGB-CBM™series features sliding layers sintered on 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 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.
Bearings made of the GGB-CSM and GGB-CBM materials are available by special order to customer-supplied designs and drawings.
Also available from GGB is 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, coupled with the bearings’ innovative design, make them suitable for replacing more costly bearings in many applications, such as automotive seats and convertible tops.
FLASH-CLICK 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.
