RS-SS-Chain-british Standard Chain-BS-SS-Drive Chain

The Tsubaki BS-SS Chain is engineered for demanding and special environments, including use in water, acidic, and alkaline applications. It maintains reliable performance across a wide temperature range, from low to high temperatures (-20°C to +400°C). The parts utilize 18-8SUS (SUS304 equivalent) stainless steel, which is marginally magnetic due to the cold-forging process.
