As a leading manufacturer from Hebei Speed Torque Transmission Technology Co., Ltd., established in 2017 with an ISO9001-certified facility spanning 3,000–5,000 square meters, we are proud to present our Roller Chain Coupling designed to meet both American (ANSI) and European (ISO/DIN) standards. With over 100 dedicated employees and an annual export value between US$5 million and US$10 million, we deliver reliable power transmission solutions for industrial drives worldwide. This coupling combines rugged construction with versatile interchangeability, ensuring seamless integration into existing systems across North America, Europe, Southeast Asia, and beyond.
Our roller chain coupling is engineered to transmit torque efficiently while accommodating angular, parallel, and axial misalignment, extending equipment life and reducing downtime. Whether you need a compact design for light-duty applications or a heavy-duty version for demanding environments, our standard product line covers a wide range of bore diameters and torque capacities. The use of hardened alloy steel sprockets and heat-treated chains guarantees durability even under continuous operation. Additionally, the coupling is available in single-strand or double-strand configurations, giving you the flexibility to match specific power requirements.
Key Features of Our Roller Chain Coupling
Dual-Standard Compatibility: Conforms to ANSI and ISO/DIN dimensions, making it suitable for both American and European machinery without modification.
High Torque Density: Compact design delivers high torque relative to size, ideal for space-constrained installations.
Easy Installation: Slip-fit sprockets with keyways allow quick mounting onto shafts; no special tools required.
Misalignment Management: Accommodates up to 0.5°–2° angular misalignment and 0.5–2 mm parallel offset, reducing stress on bearings and seals.
Maintenance-Free Option: Available with self-lubricating chain or sealed covers for extended service intervals.
Wide Material Selection: Standard in carbon steel (zinc-plated), with optional stainless steel for corrosive environments.
Custom Manufacturing: Bore sizes, keyway dimensions, and overall length can be customized per customer drawings.

Frequently Asked Questions
Q: What materials are used for this roller chain coupling?
A: The standard material is hardened alloy steel with zinc-plating for corrosion resistance. We also offer stainless steel (304/316) for food-grade or chemical environments.Q: Can the coupling accommodate misalignment?
A: Yes, it can handle angular misalignment up to 2°, parallel misalignment up to 2 mm, and axial float up to 4 mm, depending on the chain slack and cover design.Q: Are your couplings interchangeable with brands like Rexnord or Lovejoy?
A: Yes, our dimensions follow ANSI and ISO standards, so they can directly replace most market-leading coupling brands of equivalent sizes.Q: What is the typical lifespan of the coupling under normal operation?
A: With proper installation and occasional lubrication (if not sealed), the chain and sprockets can last 3–5 years in continuous duty. Sealed versions may last longer.Q: Do you provide a safety cover?
A: Yes, we offer optional steel or aluminum covers with gaskets for dust and moisture protection. They can be ordered as part of the assembly.Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, MOQ is 1 piece for samples. For mass production, MOQ is typically 10 pieces per size. Custom orders may have a higher MOQ.Q: How do I select the correct coupling size for my application?
A: Please provide the shaft diameters, torque requirements, RPM, and any misalignment conditions. Our technical team will recommend the optimal model.Q: Can I get a coating other than black oxide?
A: Yes, we can apply electro-galvanizing, hot-dip galvanizing, or colored paint upon request.
