Metal information:
1. Cast iron is generally gray cast iron; wear-resistant cast iron; ductile iron is suitable for low-speed light load; or open-type transmission bearing mechanism: sheet or spherical graphite composition in the guess; cover the surface to form a smooth graphite layer.
2. Bearing alloy
ZChSnSb10-6 has good corrosion resistance; strong anti-adhesive ability; fast connection with steel back; expensive; suitable for high speed and heavy load; such as rolling stock.
ZChPbSb16-16-2 has poor resistance to gluing; poor thermal expansion; brittle for medium speed medium load.
This kind of babbitt alloy has good wear resistance; it is resistant to gluing; it has large thermal conductivity; it is most suitable for bearing material.
3. bronze
ZCuPb30 is cast or sintered attached to the inside and outside of the steel back bush. A double metal; excellent anti-gluing function
ZCuSn10-l anti-friction and wear resistance are very good; the most excellent bearing material; high-speed heavy-duty such data hardness and strength is higher than that of babbitt; corrosion resistance; but poor running-in; the matching journal needs are higher Hardness and finish; suitable for medium speed and heavy load.
4. Aluminum alloy - bimetallic low tin aluminum alloy; containing Sn0. 5%
High-tin aluminum alloy; containing Sn20%; locomotive diesel engine with such information high intensity; corrosion resistance; good thermal conductivity.
5. Ceramic metal iron powder ten graphite powder or copper powder ten graphite powder → restricted forming → burning layout into pore layout; pores accounted for 15 ~ 35% → oil-soaked → oil bearing.
This kind of bearing bush is only suitable for smooth load and medium and small speed because of poor tolerance; it is used in occasions with poor smooth conditions.
Non-metallic materials:
Easy to run and wear debris;
Small possibility of bonding with the journal affinity
1. Plastic: phenolic plastic; polyacetal (nylon), polytetrafluoroethylene has greater compressive strength; anti-adhesion and wear resistance; good corrosion resistance; friction coefficient. Ï„ èŒ å©€æƒ´ å å å æ—¢ æ—¢Vision is full of phoenix
2. The rubber is made of hardened rubber; it is used for the shaft to oscillate and skew; the case is more dirty; the water is smooth, the bearing bush layout is integrated, the whole casting split type

Mild steel, sometimes referred to as carbon steel or ordinary carbon steel, is defined as having a carbon content of no more than 2% and no other perceptible alloy elements.
This steel is produced on a large scale and is the largest part of the steel production industry. You will be able to find it in various applications, fasteners and fasteners.
Generally, this kind of steel has high strength, high hardness and magnetism, and is usually used in motors and electrical appliances - however, their corrosion resistance is poor, and should not be used in corrosive environment without protective coating or coating.
There are some differences between low-carbon steel and steel, because steel has lower toughness and greater brittleness, and low-carbon steel can be further strengthened by adding carbon.
