About 12BSS-3 Stainless Steel Roller Chain
12BSS‑3 is triplex 304 stainless‑steel roller chain complying with ISO 606 / DIN 8187 standard, pitch 19.05 mmiwis. Its triple‑strand construction delivers superior tensile strength and heavy‑load performance compared with simplex and duplex versions.
Precision‑machined solid rollers and bushings enable low‑friction, stable power transmission. Made of 304 stainless steel, it resists rust, moisture, weak acid and salt‑spray conditions. Widely used for heavy‑duty power‑transmission and conveying in food machinery, marine equipment and chemical processing lines. Custom attachments, offset links, connecting links and matched sprockets are available.
