GGB-DB® cast bronze bearings are maintenance-free bearings designed for heavy-duty industrial applications, featuring solid lubricant inserts of PTFE or graphite for operation up to 350°C. They are available in cylindrical, flanged, thrust washer, and custom forms, with a minimum yield strength of 97 N/mm² and maximum dynamic load capacity of 70 N/mm² for the lower-rated variants. Maximum sliding speed is 0.5 m/s, and the coefficient of friction in dry conditions ranges from 0.05 to 0.18. Operating temperature ranges from -50°C to 180°C for graphite-lined variants and up to 350°C for PTFE-lined variants. The bearings are intended for use with housing tolerances H7 and shaft tolerances d8, with a recommended surface roughness of 0.2-0.8 µm on the shaft.
