GGB DP11™ Metal-Polymer Low Friction Composite Bearings 08 DP11

DP11 is a metal-polymer plain bearing designed for dry-running applications with high-frequency, low-amplitude oscillating movements, suitable for automotive and industrial use. It features a bronze backing with a sintered porous bronze layer and a PTFE-based solid lubricant sliding surface. Operating temperature ranges from -200°C to 280°C, with a maximum static load of 250 N/mm² and dynamic load of 140 N/mm². Sliding speed reaches 2.5 m/s dry and 5.0 m/s oil-lubricated, with a coefficient of friction between 0.04 and 0.25 dry and 0.02 to 0.08 when oil-lubricated. The material is lead-free and compliant with RoHS, WEEE, and ELV standards, and meets FMVSS 302 for flammability. Shaft surface roughness should be 0.3-0.5 μm for dry operation. The bearing supports linear, oscillating, and rotating motion.
