Drive Chain Gold & Black 420-112L Dream 50

By making the link plate thicker than standard products, strength is increased by approximately 1.2-1.3 times (compared to SP Takegawa).
Furthermore, it is the strongest drive chain in the 420 series, featuring SDH treatment and solid bushings.
SDH Treatment
The cause of chain elongation is wear between the pins and bushings.
When fine, hard, harmful particles such as sand and dust enter between the pins and bushings, chain wear is accelerated, causing vibration and noise, and shortening the chain's lifespan.
In such cases, the SDH treatment developed by D.I.D comes into its own.
SDH treatment forms a very hard film on the surface of the pins, and this film has high-hardness carbides dispersed within it.<
Therefore, it prevents chain wear even if hard foreign particles enter between the pins and bushings from the outside.
Solid Bushing
This is a wear-resistant roller chain that uses rigid solid bushings with seamless, smooth surfaces and excellent roundness.
Solid bushings reduce the barrel-shaped deformation of the bushing that occurs when it is pressed into the link plate, forming an optimal contact bearing surface between the pin and bushing.
