Rotational temperature rise.

With the development of science and technology, increasingly high spindle speed, speed range increasing high-speed operation of the bearing increasing stability requirements of ma chine tool spindle bearing temperature rise is to limit the speed of the bearing important factors. usually correctly select bearing type, worse grade configuration, clearance (preload) size, lubricant and lubrication method, the high-speed performance of the rolling bearing can be improved to some extent.ball bearing companies

Life and carrying capacity.

General machine tools, spindle formation of life refers to the period of use to maintain the accuracy of the spindle, therefore, requires the precision of the bearing to meet the requirements of the life of the spindle assembly. Heavy machine tools or heavy cutting machine, you should first bearing capacity air filter .industrial bearings

3. Stiffness and vibration resistance.

In order to ensure the quality of the machine s processing, the spindle system must have enough stiffness Otherwise, there will be a larger complex mapping error even quiver. Vibration resistance is the ability to anti affected by forced vibration and self-excited vibration. Spindle formation vibration resistance depending on the spindle and bearing stiffness and damping. preload Rolling can effectively improve the rigidity of the spindle system.

4. Noise.

In a high-speed grinder grinding head bearing noise is an important component of the whole noise, and so should be used in low-noise rolling bearing.bearing sales
