For off-road software, chain must be promoted with upgraded metal alloy for all parts, subject to going through exceptional heat-managing procedure as well, to remarkably strengthen its toughness in opposition to rugged terrain riding.
YHK employs chromized pin and solid bushing into this chain to improve up its put on stamina and shock absorption. Its excellent performance does help inviting enjoyment and exhilaration to bicycle owner while heading severe.
CAM CHAIN (Timing chain )
It is basically made for substantial speed managing. Specific and sufficient heat-remedy generates tougher hardness in opposition to friction and superior strength against exhaustion.
With coexisting capabilities of stretch resistance and lower sounds, this chain is noticeably advisable for engine timing software.
SILENT CHAIN (Silent chain )
This series is exactly fabricated with greater grade of alloy materials for engine timing application. With advanced stamping method on hyperlink plates and exceptional heat-treatment method, it maximizes the make contact with region with sprocket and largely decreases chain extend due to the fact of exceptional friction and affect resistance. Of course, the working noise is significantly reduced at the very same time. The integrated houses of YHK silent chain qualify alone as an excellent selection for sleek participating mechanism and minimal power reduction in electrical power transmission.
