Bearing alloy should have the following properties:

1, good performance of reducing friction. Request made by bearing alloy and shaft bearing of the friction between the coefficient to small, and have good lubrication performance
 
2, can have certain compressive strength and hardness can withstand the turning to the accumulated pressure axis; But the hardness is unfavorable and exorbitant, lest wear shaft neck.

3, plastic and impact toughness good. So that can withstand the vibration and impact load, the shaft and bearing cooperate good.

4, surface performance is good. That is a good anti-bite, compliance and embedded hidden sex.

5, have good thermal conductivity, corrosion resistance and thermal expansion coefficient of small.
