Material: Thermoplastic polyamide 6.6, die cast. Color: natural.Polyamide is very well suited for the manufacture of plain bearings due to its good sliding characteristics and strong wear resistance even at dry-running conditions and because of its sufficient mechanical strength and excellent corrosion resistance. Surface pressure max.: 18 N/mm², dependant on sliding speed and bearing temperature Sliding Speed:2 m/s Lubrication: usually not required Bearing clearance: about 0.01 mm per mm shaft-Ø Bearing temperature: Should not exceed 80°C. With thin-walled parts, the frictional heat is dissipated extremely well. Coefficient of linear expansion: 8 x 10^-5 Moisture absorption max.: 7.5% Moisture absorption at 20°C and 50% rel. humidity: 2.4% Mounting hole: tolerance H7
