Diamond Roller Chains Supplier — Allied Industrial Corporation
Every machine that moves, conveys, lifts, or harvests in India relies on one simple truth - the chain must not fail. Allied Industrial Corporation is an Authorised Dealer and Distributor of Diamond Roller Chain & Sprockets in Eastern India. Diamond Chain offers a range of chains designed to tackle the challenges of corrosion, abrasion, lack of lubrication and shock loadings.
We are Kolkata's authorised Diamond (TIDC India) chain dealer since 1969, we've spent over 55+ Years making sure that backbone never breaks. This page is your complete guide to roller chains — what they are, how to choose the right one, full specifications, pricing and why thousands of Indian industries trust Diamond chains over every alternative.

1) Small and large pitch (4mm up to 4 inch) chain, 2) Adapted Transmission Chain, 3) Hollow bearing pin chain, 4) Nickel Plated Chain, 5) Zinc Plated Chain, 6) Extended pitch chain, 7) Sidebow chain, 8) Cranked link chain, 9) Bush chain, 10) Oilfield Chain.
How Roller Chains Are Engineered to Last
Diamond roller chains from TIDC India are built from cold-drawn alloy steel wire that is precisely formed, case-hardened and heat-treated to international tolerances. What separates Diamond from generic alternatives is a proprietary pin surface treatment process that delivers 3 to 3.5 times the wear life of a standard pin — critical in Indian factory conditions where dust, heat and inconsistent lubrication are realities, not exceptions.
All Diamond roller chains are manufactured to ASME/ANSI B29.1, ISO 606, BS 228 and DIN 8187 standards — guaranteeing dimensional interoperability with any standard sprocket worldwide.
