Rich themes: In addition to the regular exhibition, a series of seminars and activities were also held during the exhibition, covering new energy, future automobile maintenance, auto parts industry career development and many other fields. In addition, there are intelligent driving, racing, classic car display, car painting and other elements of the exhibition, to bring more rich and wonderful experience to exhibitors and visitors.

Angular contact ball bearings are a type of precision bearing designed to support combined radial and axial loads, as well as pure axial loads, in a specific direction. These bearings are engineered with raceways in the inner and outer rings that are designed to accommodate high-speed and high-precision applications, particularly in machinery and equipment where precise positioning and controlled motion are essential.

   - Needle Roller Bearings: Needle roller bearings feature cylindrical rollers with a much smaller diameter-to-length ratio compared to cylindrical rollers. This design allows for a higher load-carrying capacity in a compact space, making needle roller bearings suitable for applications with limited radial space.

A cylindrical roller bearing is a type of rolling-element bearing that is designed to provide support for heavy radial loads and moderate axial loads. It consists of cylindrical rollers held in place by inner and outer rings, with the rollers positioned parallel to the axis of the bearing. Cylindrical roller bearings are widely used in various applications where high load-carrying capacity and rigidity are required.
