ANSI NP Chain is a Tsubaki ANSI G8 chain that has been plated with Nickel. NP chain has a light corrosion resistance and an attractive appearance. NP chain is suitable for outdoor conditions exposed to water. There is a 15% reduction in Maximum Allowable Load compared to the corresponding ANSI G8 chain, so please take this into account when making your chain selection. The working temperature range is:
-10°C to +60°C. Of course, ANSI Lambda NP chain is also available.
