Hebei Speed Torque Transmission Technology Co., Ltd. proudly presents our ISO Certified Steel Flexible Tyre Coupling – a robust and reliable solution for demanding shaft connection applications. Engineered with high-grade steel and precision manufacturing, this coupling delivers exceptional durability and flexibility, ensuring smooth power transmission even under heavy loads. Our factory, spanning 3,000-5,000 square meters and staffed by over 100 experienced professionals, has been dedicated to producing top-tier transmission components since 2017. With annual exports ranging from US$5 million to US$10 million, we serve clients across North America, Europe, Asia, and beyond.
This flexible tyre coupling is designed to accommodate misalignment, reduce vibration, and protect connected machinery from shock loads. Its unique tyre-shaped elastomeric element, combined with a steel hub, provides both strength and elasticity, making it ideal for heavy-duty industries such as mining, steel mills, cement plants, and material handling systems. Below, we detail the key features and specifications that set this coupling apart.
Key Features & Benefits
High Load Capacity: The steel construction and reinforced tyre element withstand extreme torque and axial forces, ensuring long service life.
Flexible Misalignment Compensation: The tyre design absorbs parallel, angular, and axial misalignments up to certain limits (see table), reducing stress on bearings and seals.
Vibration Dampening: The elastomeric insert effectively dampens torsional vibrations and shock loads, enhancing system stability and operator safety.
Easy Installation & Maintenance: Simple two-piece design allows quick assembly without special tools. The tyre element is replaceable, minimizing downtime.
ISO9001 Certified Quality: Our entire manufacturing process adheres to ISO9001 standards, ensuring consistent performance and reliability.
Corrosion Resistance: High-quality steel with optional surface treatments (paint, galvanization) for harsh environments.
Customizable Options: Bore sizes, keyways, and overall dimensions can be tailored to customer requirements upon request.

Frequently Asked Questions (FAQ)
Q: What makes a tyre coupling different from other flexible couplings?
A: Tyre couplings use a rubber or elastomeric element shaped like a tyre, providing excellent misalignment absorption, vibration dampening, and shock load protection. They are particularly suited for heavy-duty applications where flexibility and durability are critical.Q: Can this coupling handle high misalignment?
A: Yes, the steel flexible tyre coupling can accommodate parallel misalignment up to ±1.5 mm, angular misalignment up to ±1°, and axial misalignment up to ±2 mm (depending on size). For extreme misalignment, consult our engineering team for custom solutions.Q: Is the tyre element replaceable?
A: Absolutely. The elastomeric insert is designed to be replaced without removing the hubs from the shafts, simplifying maintenance and reducing downtime.Q: What bore sizes and keyways are available?
A: We offer a wide range of standard bore diameters from 20 mm to 150 mm. Custom bores, keyways, and taper lock systems are available upon request.Q: What materials are used for the tyre element?
A: Standard material is natural rubber, offering good resilience and temperature resistance. For higher temperatures or chemical exposure, polyurethane or specialty elastomers can be selected.Q: Do you provide ISO9001 certification for this product?
A: Yes, our entire factory is ISO9001 certified, and we can provide a certificate upon request for each shipment.Q: What is the typical lead time?
A: For standard sizes, lead time is 15–25 days. Custom orders may require 25–35 days depending on complexity. We can expedite urgent orders based on stock availability.Q: How do I select the correct coupling size for my application?
A: Please provide parameters such as torque, speed, shaft sizes, and misalignment values. Our technical team will recommend the optimal model or design a custom solution.
