ANSI Neptune™ Chain
ANSI Neptune™ Chain is a Tsubaki ANSI chain that has undergone a special surface treatment. The link plates, bushes and pins have a special two stage layer applied in order to provide the maximum protection from the operating or environmental conditions. (Spring clips are SUS301). Neptune™ rollers have a special coating designed to resist the corrosive conditions as well as the severe dynamic contact between roller and sprocket.

- Connecting links are clip type for sizes RS35-NEP to RS60-NEP, and cotter type for size RS80-NEP.
- When a single pitch offset link is used, please calculate a 35% reduction of the fatigue strength.
