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. .

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.
