Four -point contact ball and other section thin wall bearings (X type)

The section thin -walled bearing is composed of seven open series and five seal series. There are three types of opening series: radial contact C, angle contact type A, and four -point contact X. Advantages of cross -sectional bearing such as thin walls: thin -walled bearings realize extremely thin bearing section surfaces, and also realize the miniaturization and lightweight of the product. The diversity of the product has extended its scope of use.
The characteristics of section bearing products such as thin walls: In order to obtain the low friction torque, high rigidity, and good return accuracy of the bearings, a small outer diameter steel ball is used. The use of mid -air shafts ensures space for lightweight and wiring. The thin -walled 6700 and 6800 series include various dust cover forms, forms of flange, stainless steel form, wide -amplifier forms, etc., with complete varieties.
The main use of section bearing such as thin walls: step motor, medical device, office equipment, detection instruments, deceleration. Variable gear device, robot, optics. Image equipment, rotating encoder.
The cross -section bearing such as thin walls is also called thin -walled ring bearing. It is highly accurate, very quiet, and has a strong carrying capacity. The thin -walled ring bearing can be deep groove ball bearings, four -point contact bearings, angle contact ball bearings, thin -walled bearing horizontal cross sections are mostly square. In these series, even the larger axis diameter and bearing holes, the cross section remains unchanged. These bearing is therefore called an alien.
