New metal-polymer bearing material offers low friction resistance
Product News Thursday, January 27, 2011: GGB (formerly Garlock Bearings)
GGB Bearing Technology, formerly Glacier Garlock Bearings, has developed a PTFE-based, metal-polymer bearing material for industrial applications requiring low friction and excellent dry wear resistance. These include cutting equipment, textile machinery, clutches, dampers, belt tensioners and flywheels, among others.
Called DP™11, the new material provides improved dry wear performance under high-frequency and low-amplitude oscillating movements, even at high operating temperatures. The specific material structure of the bearings -- steel backing, porous bronze interlayer and sliding layer of PTFE with solid lubricant and fillers – allows them to withstand maximum static loads of 250 MPa and maximum dynamic loads of 140 MPa. The bearings are capable of sliding speeds up to 2.5 m/s dry, and are suitable for use under operating temperatures ranging from -200°C to +280°C. Manufactured to low tolerances for reduced operating clearances, the dry-running bearings eliminate the need for lubrication and maintenance.
The DP11 material is available in a variety of configurations manufactured to users’ specific requirements, including cylindrical and flanged bearings, strip, modified standard components, thrust washers, flanged washers, half bearings, flat components, deep-drawn parts, pressings and stampings. The DP11 material complies with both the EU ELV directive and RoHS regulation.
