The particularity of the rolling bearing technology

Spindle bearing oil is NSK Bearing a precision machine tool spindle bearing special lubricating oil and similar equipment, it to ensure the accuracy of the spindle work and use of performance, prolong its service life plays a very important role, is also called the bearing oil.

The main performance:

1. Proper viscosity and good viscosity-temperature characteristic

To make the machine tool spindle temperature is not too high and make the machine tool thermal deformation, affect the machining accuracy or make poor lubrication bearing, should according to the structure of the spindle bearing, speed and bearing clearance to choose appropriate temperature of lubricating oil and requires its good viscosity-temperature ­ features, preventing spindle working temperature and environmental temperature change is big, the change of the viscosity is too large and influence its lubrication performance.

2. Good lubricity

To keep between shaft and bearing contact surface have a uniform oil film, and in the main shaft impact load of oil film start or stop the movement also not dent, keep good lubrication performance plays a reduce friction and friction heat, lowering the temperature rise of the spindle, the action of ­ guarantee machining accuracy, requires good lubrication performance.

3. Good oxidation resistance

Machine tool spindle when using circulation lubrication method, for the main shaft bearing oil use for a long time without metamorphism has good oxidation resistance is required.

4. Good rust resistance

Because the oil in the working process of the spindle lubrication system will inevitably mixed with condensed water or machine cooling fluid in the air, so the oil has good anti-rust property.

The production characteristics of rolling bearing, determines the process has the following three characteristics:

Specialization of 1.

Bearing parts processing, a large number of bearing use special equipment. Such as steel ball processing using grinding ball machine, grinding machine, etc. Professional characteristics also reflect in the production of bearing parts, such as specializing in the production of steel ball steel ball company, specializing in the production of miniature bearing of miniature bearing factory, etc.

Automation 2.

Bearing production specialization of production automation provides the conditions for it. In the production of a large number of using full automatic, semi-automatic and special machine tools for special purpose, application and production of automatic line gradually. Such as heat transfer machine and automatic line for assembling, etc.

3. Advanced

As the large size of bearing production requirements, making the use of advanced machine tools, tooling and process possible. Nc machine tools, such as three jaw floating chuck and protective atmosphere heat treatment, etc.
