FAQs — Rubber Top Chains

What industries use Diamond Rubber Top Chains?

Diamond Rubber Top Chains are widely used across wood and timber processing, glass and ceramic tile industries, carton and corrugated box manufacturing, printing and publishing, PVC pipe and cable extrusion (haul-off), food and beverage packaging, pharmaceuticals, optical fibre cable production, and automotive component handling. Essentially any industry where products are conveyed on a chain but cannot be scratched, dented, or allowed to slip. Allied Industrial Corporation supplies to all these sectors across Kolkata and Eastern India.

What is the difference between NBR and Polyurethane rubber top chains?

NBR (Nitrile Buna Rubber) is the standard material — hardness 65–80 Shore A. It offers excellent oil, fuel, and abrasion resistance, making it the go-to choice for general industrial conveyors including printing, glass, and wood lines. Polyurethane (PU) has higher hardness (70–90 Shore A), superior tear and chemical resistance, and longer wear life — making it the preferred choice for high-wear applications like PVC extrusion haul-off machines and wire/cable lines. Allied Industrial Corporation can advise the correct rubber grade for your specific application.

What is the minimum order quantity for Rubber Top Chains from Allied Industrial Corporation?

For standard stocked items (08B-G1, 08B-G2, 12B-G1), Allied Industrial Corporation can supply from 1 metre for B2C retail customers. For custom profiles or special rubber grades, a minimum order of 10–25 metres typically applies, depending on TIDC India's production run. Bulk B2B orders from 50 metres qualify for preferential pricing and expedited delivery across Eastern India.

How do I maintain a Rubber Top Chain to maximise its life?

Lubricate the base roller chain (not the rubber) using Diamond chain lubricating oil — keep lubricant off the rubber top to prevent surface degradation. Inspect rubber pads every 250–500 hours of operation for hardening, cracking, or detachment. Replace the chain when rubber shows cracking beyond 2mm depth or when base chain elongation exceeds 0.3% of nominal pitch. Never run a rubber top chain through an oil bath — the rubber will swell and deteriorate. Allied Industrial Corporation can advise on correct lubrication methods for your specific installation.

Do you offer replacement chains for imported machinery?

Yes. We stock British Standard (BS), American Standard (ANSI), and DIN chains to cover replacement needs for both Indian and imported industrial machinery.
