What kind of material does the bearing seat have?
Bearing and bearing lining materials commonly used for metal materials and nonmetal materials, two kinds of common gray iron, cast iron, ductile iron suitable for low speed and light load, or bearing seat open transmission mechanism: flake and spheroidal graphite component in the material, covering the lubrication layer formed on the surface of graphite.In order to reduce friction, wear demands of bearing materials, in addition to the requirements of friction between the friction coefficient, wear but also should satisfy the following points. Should have enough compressive strength, fatigue strength and impact ability. The bearing base alloy thickness is (0.013-0.13) mm. Good adhesion resistance. When the load is big, the speed is high, the bearing seat clearance is too small, the surface finish is not high, the lubrication is bad, we should pay attention to carefully select the material matching, to prevent friction pairs of adhesion, wear, a glue. Having the ability to adapt and hold foreign bodies. Materials of low hardness, good plasticity and low coefficient of elasticity have good adaptability and the ability to hold foreign bodies. Good corrosion resistance, low price, sufficient source. The formation of colloidal deposits after oxidation is corrosive to the bearing material.
General cast iron more, steel, aluminum alloy, zinc alloy also has
There are many kinds of bearing housingsIron, cast iron, stainless steel, zinc alloy, plastic, etc
