Dongbo NOS Chain is a chain that allows life extension without additional refueling by installing a special bush containing oil. It is the best chain to be selected when refueling is not possible or limited refueling is possible due to its nature of use. Self-lubrication also significantly increases the chain's life span. When using low speed – 40 times the standard type, you can extend your life by at least 10 times when using normal speed. As there is no additional refueling, oil contamination is prevented in advance, allowing cleanliness and low noise use, and special coating treatment on the surface prevents corrosion. Designed to have the dimensions and breaking strength of the standard roller chain, it is compatible with existing sprockets and can be installed without any facility changes.
