Roller Chain & Conveyor Chain Manufacturer
— Over 40 Years of Experience

UIB Chain is a professional manufacturer of industrial chains and matched sprockets. We supply chains for a wide range of applications — general machinery equipment, motorcycle, mining, construction engineering and food-grade processing — so that each market is served with a chain built for its working conditions rather than a one-size-fits-all part.

Our product portfolio uses globally standardized raw materials, selected to match each customer’s actual operating requirements. The material range covers 40Mn carbon steel chains, as well as stainless steel chains in SUS304, SUS420, SUS316 and SUS318 grades. Nickel plated and zinc plated chains are available on request.

Backed by an engineering team with more than 40 years of industry experience, we deliver targeted and reliable product solutions efficiently — from standard transmission and conveyor chains to non-standard chains made to your drawing or sample.

What We Supply

• Transmission chains — ANSI A-series and ISO/BS B-series roller chains, simplex to triplex. View transmission chains
• Conveyor chains — double-pitch C-series and heavy-duty conveyor chains for material handling. View conveyor chains
• Stainless and plated chains — SUS304, SUS316, SUS318 and SUS420 grades, plus nickel and zinc plated chains for food, washdown and outdoor use. View stainless chains
• Single strand chains — simplex roller chains for general drives and light conveying. View single strand chains
• Multi-strand chains — duplex and triplex chains that carry a higher load in the same pitch. View multi-strand chains
• Attachment chains — A1, A2, K1 and custom attachments for conveying and indexing. View attachment chains
• High temperature chains — heat-resistant chains for ovens, kilns, foundries and baking lines. View high temperature chains
• Custom sprockets — machined to your drawing; send us the chain number, tooth count and bore size. View sprockets

Applications We Serve

Chains are selected by application, not only by size. Tell us the working conditions — load, speed, temperature and environment — and we will recommend the right chain, material and lubrication.

• General machinery equipment — drive chains for pumps, compressors, conveyors and production lines.
• Motorcycle — drive chains and sprockets for motorcycle and powersports applications.
• Mining — heavy-duty and conveyor chains for crushers, screens and bulk material handling.
• Construction engineering — chains for concrete, asphalt, lifting and earth-moving equipment.
• Food-grade — stainless steel chains for food processing, washdown and packaging lines.

Send us the chain number (or a photo with a ruler), the quantity and the length you need — our engineers will confirm the correct part and reply with a quotation. Request a quote
