What are the commonly used sliding bearing bushing materials
(3) oilless bearings. It is a kind of porous material which is made of bronze and cast iron powder, pressed by heavy graphite, and sintered by high temperature. It is often used in low or medium speed, light load and inconvenient lubrication.(4) nylon. Nylon, nylon 6 and nylon 1010 are commonly used. The nylon bearing has the advantages of good running and good quality, soft fragments after wear, no damage to the shaft neck, good corrosion resistance, etc. the heat conductivity is poor, and the water can swell when the water is absorbed.
(1) grey cast iron. It is used in low speed, light load and no impact load. HT15-33 and HT20-40 are often used.(2) steel base bearing alloy. ZQSn10-1 bronze and ZQA19-4 aluminum bronze are commonly used, suitable for medium speed, high turbidity and impact loading.
(5) bearing alloy (Babbitt). It is an alloy of tin, lead, Li, antimony and so on. Has good abrasion resistance, but the intensity is low, the bearing can not be made individually, usually cast in iron and steel, Qingdao Steel Bearing base.(6) three layer load bearing materials. There are two kinds of composite materials: poly acrylic steel, ethylene steel body composite material and POM steel body composite material.
