KCM Roller Chain Range — Quick Reference (BS + ASA)
KCM = reliable industrial roller chain brand supplied across drive + conveyor applications. AIMS stocks KCM roller chain in both BRITISH STANDARD (BS) + AMERICAN STANDARD (ASA) simplex configurations + connecting links + offset (crank) links + stainless variants for repair + assembly. Manufactured to ISO 606 / BS 228 (BS) + ANSI B29.1 / ASME B29.100 (ASA).
| KCM Chain Type | Best For |
|---|---|
| BS Simplex (06B / 08B / 10B / 12B / 16B / 20B) | British standard pitch — common AU + European drives |
| ASA Simplex (40 / 50 / 60 / 80 / 100 / 120) | American standard pitch — US-origin + automotive |
| BS Duplex / Triplex | Higher load + redundancy in critical drives |
| ASA Duplex / Triplex | Higher capacity ASA pitch chains |
| Connecting Links (Spring / Cotter) | Joining chain ends + maintenance |
| Offset / Crank Links | Odd-length adjustment — single-pitch offset |
| Stainless 304 / 316 Variants | Food + marine + corrosive + chemical |
| Self-Lubricating Variants | Difficult-to-lubricate installations |
Critical: BS and ASA chains are NOT INTERCHANGEABLE — pitch differs. BS 06B pitch = 9.525mm; ASA 40 pitch = 12.7mm. Specify pitch + chain type when sizing. Stretching > 3% = chain replacement (worn + sprocket damage). Match sprocket teeth to chain pitch + width. Brand: KCM. Companion: roller chain, chain + sprockets, sprockets, roller chain guide.
KCM Roller Chain — British Standard & American Standard Simplex
KCM is a reliable industrial roller chain brand supplied across a wide range of drive and conveyor applications. AIMS Industrial stocks KCM roller chain in both British Standard (BS) and American Standard (ASA) simplex configurations, along with connecting links, offset (crank) links and stainless variants for repair and assembly. Manufactured to ISO 606 / BS 228 (BS chain) and ANSI B29.1 / ASME B29.100 (ASA chain) dimensional standards.

BS vs ASA roller chain — which standard?
British Standard (BS) chain — used across Commonwealth-specified Australian, UK and European machinery — is identified by pitch in millimetres and inches (e.g. 08B = 1/2" pitch). American Standard (ASA / ANSI) chain — used across imported US machinery, mining equipment and many Australian OEM products — is identified by ANSI number (e.g. 40 = 1/2" pitch). The pitch values can be identical but the side-plate and roller dimensions differ — BS and ASA chains are NOT interchangeable on the same sprocket. Always confirm which standard the existing drive uses before ordering replacement chain.

Chain selection & maintenance
Roller chain capacity is a function of pitch, breaking load, hp/kW rating at design rpm, and service factor for the application class. For background on choosing between belt and chain drives — when each is the better engineering choice — see our belt vs chain drives guide. For chain drive tensioning best practice (over-tight is the most common cause of premature chain wear), see our chain tensioner guide.
