What are the common sliding bearing bushing materials? What are the characteristics of each?
5) bearing alloy (Babbitt). It is tin, lead, copper, antimony and other alloys, with good wear resistance, but low strength, can not be made into separate bearings, usually cast in bronze, cast iron, steel and other bearing matrix.6) three layer load bearing material. Commonly used in two kinds: polypropylene, polypropylene, steel body composite materials and POM steel body composite.
3) oily bearing: generally use bronze, cast iron powder, the amount of graphite pressing forming, sintered by high temperature porous material. It is often used in low or medium speed, light load and inconvenient lubrication.4) Niron. Commonly used nylon 6, nylon 66 and nylon 1010, nylon bearings with running and good, the debris after the soft surface does not hurt the shaft neck, corrosion resistance and other advantages, poor thermal conductivity, water will swell.
1) grey cast iron, which is used in low speed, light load and no impact load, and is commonly used in HT15-33 and HT20-40.2) copper base bearing alloy. Commonly used ZQSn10-1 bronze and ZQA19-4 bronze, suitable for medium speed, high turbidity and impact load conditions.
