Weyeah Power connecting rod bearings are known for their high quality, durability, and cost-effectiveness. They are made of high-end materials and manufactured using the latest technology. They are produced by internationally renowned OEM manufacturers and feature advanced international quality control and testing technology. They are suitable for high-silicon gas engines and have comparable material, technology, and production processes to MIBA.

On connecting rod bearings, splash bearings are usually installed as upper bearings, while on main bearings, they are usually installed as lower bearings. "Splash" is a physical vapor deposition (PVD) process that can coat aluminum-tin plating onto the bearing surface.
