（1）、减少摩擦及摩损。

(1) to reduce friction and friction.

在构成深沟球轴承的套圈、动弹体及保持器的相互接触部门，防止金属接触，减少摩擦、磨损。

To prevent metal contact and reduce friction and wear, the contact Department of the ring, the dynamic projectile and the maintainer of the deep groove ball bearing can prevent the contact of metal.

（2）、延长疲惫寿命。

(2) to prolong fatigue life.

深沟球轴承的动弹疲惫寿命，在旋转中，动弹接触面润滑良好，则延长。相反地，油粘度低，润滑油膜厚度不好，则缩短。

The dynamic fatigue life of the deep groove ball bearing is lengthened by the good lubrication of the moving contact surface during the rotation. On the contrary, the viscosity of the oil is low and the thickness of the lubricating oil film is not good, then it is shortened.

（3）、排出摩擦热、冷却。

(3) discharge friction heat and cooling.

轮回给油法等可以用油排出由摩擦发生的热，或由外部传来的热，冷却。防止深沟球轴承过热，防止润滑油自身老化。

The return of oil to oil can be used to expelled heat from friction, or heat transmitted from the outside, and cooling. Prevent deep groove ball bearing overheating and prevent the lubrication oil from aging.

（4）、其他

(4), other

也有防止异物侵入深沟球轴承内部，或防止生锈、侵蚀之效果。

It also has the effect of preventing the foreign body from invading the inner of the deep groove ball bearing, or preventing the rust and erosion.
