Description

Bronze bushing, wrapped bush, sliding bearing is based on high density copper alloy of special formula. The alloy surface is rolled to diamond or global oil grooves. It has high density, good load capacity and wear-resistant. The product is applied to lifting machinery, construction machinery and mining machinery, etc. Tech.Data. Pressure resistance strength **0N/mm2 Coefficient of heat conduction *8 W/mk Alloy hardness *0~**0 HB Alloy material CuSn8P Density 8.8g/cm3 Linear expansion coefficient *8.5x*0 *6/k Elongation *0% Bearing is made of high quality low-carbon steel backing with sintering porous bronze in its interlayer and the compound of PTFE with Pb on its surface. It can offer the good properties of self-lubricating, anti-abrasion low-friction, fully developing the advantages of metal and multi-element ***** is applied to the printing, woven, tobacco and gymnastic machinery etc. Tech, Data. Load capacity **0N/mm2 Temperature ***0oC~***0oC Speed limit 2m/s Friction coefficient 0.*8~0.*0 PV limit (Dry) 3.8N/mm2m/s PV limit (Oil ) *0N/mm2m/s Tolerance: Recommended housing bore tolerance is H7 Pay attention: We could make them into flanged bushes, thrust washers, strip and non-standard parts as clients supplied drawing and etc.
