Product Details

Metric ball bearings are a type of rolling bearings. It installs spherical alloy steel balls in the middle of the inner and outer steel rings, and reduces the friction during power transmission and improves the transmission efficiency of mechanical power in a rolling manner. Ball bearings cannot withstand large heavy loads and are more common in light industrial machinery.

The metric ball bearing mainly consists of four basic components: a ball, an inner ring, an outer ring and a cage or retainer.

Ball bearings are generally used in low load mechanical transmission equipment. Because the bearing area of the ball bearing is small, it is prone to serious mechanical damage in the case of high-speed operation. Therefore, in heavy-duty mechanical transmission, needle-type bearings are often used to increase the bearing surface, improve the mechanical transmission efficiency, and reduce Mechanical damage.

It changes the friction mode of the bearing and adopts rolling friction. This method is more effective in reducing the friction between the bearing surfaces, improving the service life of the fan bearing and thus prolonging the service life of the radiator.

Features:

1. Ball screw of metric ball bearings is produced continuously with the world's highest level of mechanical equipment. We have strict control over temperature and humidity in the grinding, assembly, and inspection of the factory environment for each process. Due to the perfect quality management system, the accuracy is fully guaranteed.

2. Since the ball screw is moved by the ball, the starting torque is extremely small, and there is no creep phenomenon like sliding motion, which ensures accurate micro feed.

3. There are many balls between the screw shaft and the nut of the ball screw for rolling motion, so high movement efficiency can be obtained.
