The Important Role of DAOLER Diamond Friction Shims in Automobile Engine Transmission System

10/20/2026
DAOLER Diamond Friction Shim plays a vital role in the automobile engine transmission system and ensures stable output under high power and high torque. Against the backdrop that modern automotive design pursues lightweight and compact structures, balancing friction between gear-to-shaft and gear-to-gear becomes particularly critical. The DAOLER Diamond Friction Shim is developed precisely to meet this challenge.

The friction shim uses diamond as the reinforcing material. Thanks to its ultra-high hardness, it can generate strong friction even within a limited contact area. With precision design and advanced manufacturing processes, DAOLER Diamond Friction Shim can reliably connect key mating parts including gear to gear, gear to sprocket, and gear to shaft. It keeps these components running synchronously to achieve efficient power transmission.

Technically, key indicators of DAOLER Diamond Friction Shim such as friction performance and matrix hardness have reached internationally advanced standards, even outperforming similar foreign products in some aspects. This is backed by our company’s profound manufacturing experience, strict quality control system and in-depth research in material science.
In addition, the manufacturing technology for this product requires relatively low investment and delivers quick returns. It helps enterprises cut R&D costs and shorten time-to-market.

In practical applications, DAOLER Diamond Friction Shim is not only used in the automotive industry, but also widely adopted in various friction transmission products. Whether for large mechanical equipment or small precision instruments, this product delivers outstanding performance wherever stable and efficient power transmission is required.
