ANSI AS Chain

Tsubaki ANSI AS Chain

The pins and rollers of this roller chain are made of precipitation-hardened, tempered stainless steel (SUS600). The link plates and the bushes are made of SUS304 stainless steel (spring clips are SUS301). The Maximum Allowable Load is 1.5 times that of ANSI SS chain. Corrosion resistance is slightly lower than standard SS chain. This chain is suitable where corrosion and heat resistance is required in a heavy duty drive application and where a smaller ANSI SS chain is preferred. Magnetism exists due to the use of precipitation-hardened SUS600. The working temperature range: -20°C to +400°C.
