Lubricating Sliding Brass Bush Oilite Bearing Sintered Maintenance Free

3.Lubricating sliding brass bush oilite bearing  sintered maintenance free   It is a self-libricating bearing materials suitable for high load low speed application which lubrications is difficult or need dry running. It is made by advanced powder metallurgy. It is based on three metal alloy types, bronze , iron and nickel each containing dry solid lubricant like graphite, molybdenum disulphide which uniformly dispersed within the metal matrix. The percentage, type and form of the solid lubricant is determined by the bearing application operating requirements in terms of specific load, sliding speed, temperature and other environmental factors.                     Material codeBronze FerrousNickelDICK85HB1DICK85HB2DICK85HB11DICK85HB12DICK85HF14DICK85HF18DICK85HN22DICK85HN23CuSn      8613/6-1CuSn      8613/12-1CuSnPb      8313/6-1CuSnPb      8413/8-1FeNiCu      8310/8-3FeCu      9404/8-2NiFeCu      6033/10-2FeCrNi      7218/20Density (g/cm3)6.867.25.865.965.8HB Hardness≥40≥50≥50≥50≥80≥50≥45≥55Compressive strength (Mpa)300180380220550180240180Max.
