Drive Chain Gold & Black 420-72L Z50J(6V)/Monkey BAJA

By increasing the thickness of the link plate compared to 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, equipped with SDH treatment and solid bushings.
SDH Treatment
The cause of chain stretch is wear between the pins and bushes.
When fine, hard, and harmful particles such as sand and dust enter between the pins and bushes, it promotes chain wear, causes vibration and noise, and shortens chain life.
In such cases, the SDH treatment developed by D.I.D demonstrates its effectiveness.
SDH treatment forms a very hard film on the surface of the pin, and this film has even higher hardness carbides dispersed within it.
Therefore, even if hard foreign particles enter between the pins and bushes from outside, it prevents chain wear.
Solid Bushing
This is a wear-resistant roller chain that uses rigid solid bushings with a smooth, seamless surface and excellent roundness.
Solid bushings reduce the barrel-shaped deformation of the bush that occurs when pressed into the link plate, forming an optimal contact bearing surface between the pin and bush.
