Machine tool spindle bearings of SKF technology requirements:
SKF bearings is widely used in the machine tool bearings. Machine tool spindle bearings, SKF certain technical requirements.ball bearing suppliers

1, the speed and the temperature rise:

With the development of science and technology, increasingly high spindle speed, variable speed range is growing, more and more high, bearing high-speed operation stability requirements. Machine tool spindle bearing temperature is an important factor to limit the speed of the bearing. Under normal circumstances, the correct choice of bearing types, the high-speed performance of the rolling bearing tolerance class configuration, clearance (preload) size, lubricants and lubrication methods can be improved to some extent.

2, the life and carrying capacity:

General machine tools, the life of the spindle assembly to maintain the accuracy of the spindle period of use, therefore, requires the precision of the bearing to maintain the performance to meet the requirements of the spindle component life. Heavy machine tools or power cutting machine, you should first consider the carrying capacity of the bearing.high speed bearing

3, stiffness and vibration resistance:

In order to ensure the quality of the machine s processing, the spindle system must have sufficient rigidity, otherwise it will produce a larger complex mapping error even flutter. The vibration resistance refers to the ability to resist forced vibration and self-excited vibrations. The spindle assembly vibration resistance depends on the spindle and bearing stiffness and damping. Using preload Rolling can effectively improve the stiffness of the spindle system.

4, the noise:

In the high-speed grinder, grinding head bearing noise is the main ingredient in the overall noise should be used in low-noise rolling bearing
