Chain Description
20A-1 HS Standard (Reinforced, ASA 100-1, 1 1/4” × 3/4”, DIN 8188) - 5 m Pack is a special type of simplex drive chain. It is standardized according to ISO 606 (DIN 8188, ANSI B29.1), meaning it is a chain of the American A-series.
The chain consists of outer links with pins and inner links with enhanced bushes, on which freely rotating rollers are mounted. The chain is made of steel. Thanks to its design and the materials used, it offers significantly higher fatigue strength than standard roller chains. It also provides excellent wear resistance, ensuring a long service life.
Construction

- Inner link – high-precision, wide-waisted profile
- Outer link – high-precision, wide-waisted profile
- Special alloy steel pin (case-hardened or through-hardened according to type)
- Seamless special steel bush with optimally cylindrical shape and high wear resistance
- Through-hardened seamless roller
Typical Applications
20A-1 / ASA 100-1 reinforced roller chains according to DIN 8188 are designed for applications with higher mechanical loads, where standard roller chains might not meet requirements for strength and fatigue resistance.
They are most commonly used as drive chains in demanding operating conditions but can also be fitted with attachments or other auxiliary components for material handling and lifting applications.
