GGB DB™ Metals and Bimetals - Maintenence Free Cast Bronze Bearings 13 DB 16

GGB-DB® maintenance-free cast bronze bearings with solid lubricant inserts are designed for heavy-duty industrial applications under high loads and intermittent operation. They are available in cylindrical, flanged, thrust, and custom forms, with operating temperatures up to 350°C with graphite inserts and up to 180°C with PTFE inserts. Maximum dynamic load capacity is 250 N/mm² and maximum sliding speed is 0.5 m/s, with a pU factor up to 1.5 N/mm²·m/s. The coefficient of friction in dry conditions ranges from 0.05 to 0.18. The bearing bore and outer diameter tolerances are specified as H10 and s6 respectively, with surface roughness requirements of 1.2 µm for the bore and 3.2 µm for the housing. The series uses bronze base material with integrated solid lubricants, and all variants share identical mechanical and tribological properties per type.
