Huzhou Dongyao Chain Industry Co., Ltd. is one of the leading manufacturers and suppliers of 25n timing chain in China. With abundant experience, we warmly welcome you to buy high quality 25n timing chain from our factory. Also, custom service is available.
Product Overview
The DYLinkar 25N Timing Chain is a high-precision transmission chain specifically designed for the engine timing system. Model 25N is made of high-quality alloy steel and undergoes enhanced heat treatment, featuring excellent fatigue resistance and dimensional stability, ensuring precise synchronization between the camshaft and the crankshaft. Its low-friction design effectively reduces internal engine wear and has good wear resistance and high-temperature tolerance. This chain is suitable for timing transmission in motorcycles, small cars, and general engines.

FAQ
Q: What is the precision standard of the DYLinkar chain?
A: The chain products of DYLinkar are produced in strict accordance with international standards, featuring high precision and smooth operation. Taking the time-conforming chain as an example, the toothed chain (silent chain) achieves transmission through the wedge engagement between the chain plate and the chain teeth. This design reduces the multi-sided effect during transmission, making the operation more stable, with low operating noise and long service life. It is widely adopted by most four-stroke motorcycle engines.
Q: Does DYLinkar offer motorcycle chain sets?
A: Yes, DYLinkar offers chain sets, which include the chain, front and rear sprockets (cog wheels), and all other necessary transmission components. The sprockets and the chain must be used in matching pairs. It is recommended to replace them simultaneously to ensure the accuracy of the transmission system and the lifespan of the components, thereby extending the overall lifespan.
Q: How often should the chain of a motorcycle be cleaned?
A: For normal riding, it is recommended to clean and apply oil at least once every 500-1000 kilometers. In case of rainy days or severe dust conditions, it is advisable to clean more frequently or perform maintenance immediately after riding.
