20A-2 / ASA 100-2 Maintenance-Free Roller Chains According to DIN 8188
20A-2 / ASA 100-2 maintenance-free roller chains (1 1/4″ × 3/4″), also known as self-lubricating or lube-free chains, are a special type of duplex drive chains. They have the same dimensions as standard roller chains according to ISO 606 (DIN 8188, ANSI B29.1), meaning they belong to the American A-series.
The chains consist of outer links with pins and inner links with bushes, on which freely rotating rollers are mounted. The chains are made of steel, while the bushes are made of a special sintered metal impregnated with lubricant.

KettenWulf Now Our Main Roller Chain Brand – KÖBO in Final Stock
After more than 15 years of offering standard roller chains from the German brand KÖBO, we have decided to discontinue their availability as of April 2025. Remaining stock will be sold off, and no further orders will be possible. These chains are being replaced by products from another German manufacturer – KettenWulf.
Why the change? In recent years, KÖBO has focused on heavy-duty conveyor chains for specialised applications and no longer offers a sufficient range or delivery flexibility in the field of standard roller chains.
KettenWulf roller chains meet the high demands of customers across all areas of application. They offer consistent quality, high load capacity, long service life and, last but not least, a reasonable price – everything you expect from a reliable solution.
Chains Construction
- Inner link
- Outer link
