In the application of machine tools, spindle precision bearings need to have good high-speed adaptability, high precision, high rigidity, low noise, low temperature rise and other performances. Spindle precision bearings are spindle bearings for precision machine tools and similar equipment. Working precision and performance. mainly include:
Precision Angular Contact Ball Bearings
Precision Cylindrical Roller Bearings
Precision Ball Screw Support Bearings
Double direction thrust angular contact ball bearing
The spindle precision bearings should be reasonably configured according to the requirements of the working characteristics of the machine tool. The purpose of the running-in operation is to make the rollers and the raceways of the bearing pass through the running-in and have good contact conditions before the bearing is formally used, so as to maintain the good contact accuracy of the bearing and avoid the initial contact between the bearing at high speed and Heavy-duty use causes damage to the rollers and raceways, thereby improving the life and precision of the bearings. Because the tapered roller bearings are not in complete rolling contact, there is sliding between the end faces of the rollers and the shoulder of the inner ring. If the contact conditions are not good, it is easy to cause damage to the bite, so more attention should be paid to the running-in operation of this type of bearing. Spindle precision bearings are spindle bearings for precision machine tools and similar equipment, which ensure the working accuracy and performance of precision machine tools.
1. High performance design
High rigidity: the number of steel balls is large, the contact angle is 600, and the rigidity is high.
Long life: EP steel with long life and high reliability is used, and the life is three times that of ordinary bearing steel SUJ2.
2. Contact sealed bearing series: high reliability, high dust resistance
The sealed bearing has good dustproof performance, and the grease is not easy to leak. And the light contact sealing ring is adopted, the bearing torque is low and the heat generation is low.
3. Easy to install
Open Bearings: Available grease filled to reduce installation time.
Sealed bearing: filled with grease, and the color of the sealing ring on the back and the front is different, easy to identify the direction.
