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.
