Firstly, Thin-walled ball bearings with equal cross-sections. Secondly, Crossed roller bearings of equal cross-section have cylindrical rollers arranged crosswise on the V-shaped raceway, and the rollers are separated by isolation blocks.

The deep groove ball bearing is a kind of rolling bearing with most representatives, and it has features of small friction coefficient, high limiting speeds, simple structure, low cost, and high manufacturing precision. It has various sizes and structures, and is used in precision instruments, low noise motors, automobiles, motorcycles and general machinery industries, and a kind of bearing with most applications in the machinery industry. The bearing can bear mainly the radial load, but also can bear a certain axial load.

Advantages of crossed roller bearings include: 1. Strong load-bearing capacity: It can withstand large radial and axial loads, and it can also withstand a certain tilt force. 2. Good rigidity: Due to the use of cross-arranged rollers, it has high rigidity and can ensure that excessive deformation and vibration will not occur during high-speed rotation.

Spherical roller bearings are widely used in various mechanical equipment, especially under severe working conditions such as heavy load, high speed, vibration and impact, and can exert their unique advantages. The following are some application areas of spherical roller bearings:

(1)HRAU series(the inner and outer rings are overall and ultra-thin) (2)HRB series (outer ring division type with inner rotating) (3)HRE series (inner ring division type with outer rotating) (4)HRU series(Integrated Inner/Outer Ring type)
