- Needle Roller Bearings: Needle roller bearings are capable of supporting high radial loads in applications with limited radial space. Their compact design and high load-carrying capacity make them suitable for use in automotive transmissions, small engines, and other machinery with space constraints.

Overall, in mechanical terms, a bearing serves as a critical component that enables controlled motion, reduces friction, and supports loads in a wide variety of mechanical systems, playing a fundamental role in the functionality and performance of machinery across industries.

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.
