Spindle bearing oil is precision machine tool and similar equipment of spindle bearing special lubricants, it to ensure that the work precision and performance, and prolong the service life of plays a very important role, also called bearing oil.

The main performance:

1. Suitable viscosity and good viscosity-temperature characteristics

To make the spindle not too high temperature and hot machine happen variant, affects the processing accuracy or make bearing bad lubrication, should be based on the structure of the spindle bearing, rotational speed and bearing clearance and choose the right temperature lubricating oil and ask its good glue temperature characteristics, main shaft work due to the temperature and environmental temperature changes greatly, the viscosity changes and to influence their lubrication performance too.

2. Good lubricity

For the spindle and bearing between a uniform interface to keep the oil film, and in the spindle start or stop motion impact load of oil film will not be destroyed, keep good lubrication performance plays reduce the friction and friction heat, reduce the temperature of the spindle and guarantee the accuracy of the processing function, should have good lubrication performance.

3. Good oxidation resistance

The spindle by circle in lubrication method, spindle bearing long-term use of oil demand and requirements of the good bad so oxidation stability.

4. Good anti-rust property

 
Because of the oil in the main shaft lubrication system in the process of work will inevitably mixing the condensed water or air cooling liquid machine, therefore, ask oil has a good anti-rust property.
