Bimetal Bushing

We supply a wide range of Engine BearingsBushingsThrust WashersAlloy Powder and Bimetallic Strips.

Bimetal bushing based on high quality low-carbon steel, with tin-lead-bronze alloy CuPb10Sn10 (Cu 10-10), CuSn6Zn6Pb3 (Cu663), CuSn4Pb24, CuPb24Sn,AlSn20Cu, CuPb30.sintered on its surface, alloy surface can be rolled to diamond or global oil hole for filling special solid lubricant or storage of grease,effectively reduce wear and tear.

Description

Bimetal bushing material

Our range of Standard Wrapped Bimetal bushing are steel backed and lined with sintered bronze. This range is extremely tough and versatile and available in metric and inch sizes. Bimetal bearings are suitable for a wide range of general purpose and heavy duty applications and can be lubricated with either oil or grease.

Steel Backed Bushing Bearings

Steel-backed bushing bearings are our standard replacement part. Our steel backed bushing with bronze, which provides excellent bonding qualities for applying the bushing lining. Bronze is a perfect bearing material–tough enough to withstand the loads and demands of rotating equipment but forgiving enough to not ruin a crankshaft in the event of a failure.

Bronze Lined Bearings/Wrapped standard bearings

The lining of these bearings is a bimetal metal. This lining is applied at the optimal thickness to ensure the best fatigue resistance and ability to embed small particles of impurity from the oil. Our industry experts can deliver high quality steel-backed bronze bearings with unbeatable price you’ll like.

CHARACTERISTICS

The JF bi-metallic self-lubricating bearing uses a high quality low carbon steel plate as the base, porous sintered bronze as the surface, suitable for oscillating and alternating rotary movements under high load conditions. Slow speed, low friction, good resistance wear, long life and better prevent snagging.The surface of the bronze layer can be machined with various grooves, oil pockets in terms of different working conditions.The product is widely used in mining machinery, automotive, construction machinery, agricultural equipment, the steel rolling industry, etc. .

Metal, Bimetal & Steel Bearings

Series bimetallic bearing material, also steel backed bronze lined materials lead or copper strip, is based on low carbon steel or steel as substrate material, the surface of sintered copper alloy steel and copper alloy products, different kinds of copper alloy material is suitable for different working condition, based on the surface can be divided into different grades of copper alloy high lead series, series of lead and lead-free series.

AVAILABLE FORMS

Bushes, flange bushes, thrust washers, strip and other non-standard parts and so on.

RemarkThe strongest type, wide application field, most suitable for high impact vibrating load bushes and Washers.Relative high fatigue strength & load capacity, good sliding performance. poor oil corrosion resistance. Fit for middle load, middle speed. Normally applied in main bushes of lnner-combustion engine. Connecting rod when plated.Good seizuring resistance good capacity to submerge foreign, overlayer plated normally applied in main bearings of high speed, low to morderate load inner-combustion engine & connecting rod bearing.Moderate fatigue strength & load capacity, good corrosion resistance, relative good sliding performance. Normally they are applied in half bush with high speed, low load inner combustion engine, air compressor, refrigerator bearings.
