415MX/420MX/428MX/520MX/525MX/530MX/630MX
For off-highway software, chain must be promoted with upgraded metal alloy for all areas, topic to heading by means of unique heat-treating procedure as well, to remarkably fortify its toughness in opposition to rugged terrain driving.
YHK employs chromized pin and strong bushing into this chain to improve up its dress in stamina and shock absorption. Its outstanding performance does aid inviting satisfaction and exhilaration to cyclist while heading severe.
CAM CHAIN (Timing chain )
It is essentially developed for higher speed operating. Specific and sufficient warmth-treatment method generates more durable hardness towards friction and excellent toughness towards exhaustion.
With coexisting capabilities of stretch resistance and reduced noise, this chain is significantly suggested for motor timing application.
SILENT CHAIN (Silent chain )
This collection is exactly fabricated with larger grade of alloy materials for motor timing application. With innovative stamping approach on website link plates and unique warmth-treatment, it maximizes the get in touch with region with sprocket and mostly decreases chain stretch because of outstanding friction and influence resistance. Of training course, the managing sound is significantly decreased at the same time. The integrated qualities of YHK silent chain qualify by itself as an best alternative for clean engaging system and minimal vitality reduction in power transmission.
Metal Front SPROCKET
The raw materials for the metal front sprocket is 20CrMnti.
Making use of skilled gear hobbing and processing technological innovation, to make the sprocket to be with high precision and common gear, and with strictly quality management and beautiful packaging, to make our solution meet the quality standard of motorcycle industry.
Metal REAR SPROCKET
The raw content for the metal rear sprocket is C45.
By means of the special forging method, to make the business of the sprocket far more specifically, we can make distinct sprockets acc. to customer’s distinct demands.
ALUMINUM ALLOY WHEEL (sprocket for motorbike race)
The uncooked materials for the aluminum alloy wheel is 7075T6.
Its lightweight and resilient traits draw in the racer, especially for its unique and faddish physical appearance and functional design and style, satisfy more large standard customers’ requirements.
