Welcome to Hebei Speed Torque Transmission Technology Co., Ltd. – your reliable partner in power transmission solutions. Since 2017, we have specialized in designing and manufacturing high-performance couplings, and our Industrial Rubber Tire Coupling is a flagship product that combines strong compensation capacity with flexible shaft connection. With a 3,000–5,000 m² factory and an annual export value of US$5–10 million, we supply this robust coupling to over 15 global markets, ensuring superior quality and on-time delivery. This coupling is engineered to absorb shock loads, dampen vibration, and accommodate misalignment, making it an ideal choice for heavy-duty industrial applications.
Product Overview
Our Rubber Tire Coupling features a unique tire-shaped rubber element that provides exceptional flexibility and torsional damping. The rubber element is bonded to two metal hubs, creating a maintenance-free, fail-safe connection. It is designed to handle high torque while compensating for angular, parallel, and axial misalignment. This coupling reduces stress on connected equipment and extends service life.
Key Features & Benefits
Strong Compensation Capacity – Compensates for radial misalignment up to ±1.5 mm, angular up to ±2°, and axial up to ±3 mm, reducing installation precision requirements.
Excellent Damping Effect – The rubber element absorbs vibrations and shock loads, protecting sensitive machinery like pumps and compressors.
Flexible Shaft Connection – Allows for easy alignment and quick replacement of the rubber element without disconnecting the hubs.
High Torque Transmission – Available torque ratings from 10 N·m to 5000 N·m, suitable for various industrial drives.
Maintenance-Free Design – No lubrication required; the rubber element is oil-resistant and wear-resistant.
Compact and Lightweight – Reduces inertia and saves space in the drive train.
Customizable Bore Sizes – Available with keyways, splines, or tapered bores to fit your shaft requirements.

Detailed Application Advantages
In industries such as mining, cement, water treatment, and material handling, our rubber tire coupling effectively reduces downtime caused by shaft misalignment. The elastic tire element is pre-compressed for a fail-safe design: if the rubber tears, the metal hubs still provide limited torque transmission, preventing sudden machine stops. Compared to jaw couplings or gear couplings, this type offers higher damping and easier replacement. The coupling is also electrically insulating, preventing stray current damage to bearings.

Frequently Asked Questions (FAQ)
What is the maximum misalignment this coupling can handle?
Depending on size, our rubber tire coupling can typically accommodate radial misalignment up to ±1.5 mm, angular up to ±2°, and axial up to ±3 mm. For extreme conditions, consult our engineering team.Is the rubber element replaceable?
Yes, the tire element can be replaced without removing the hubs from the shafts, minimizing downtime.What types of rubber are available?
Standard is natural rubber (NR). For oil or chemical resistance, we offer neoprene (CR) or EPDM. High-temperature versions (up to 120°C) are available upon request.Do you provide custom bore sizes and keyways?
Absolutely. We can machine bores to your exact specifications, including plain bore, keyway bore, spline, or taper lock.Is this coupling suitable for reversing loads?
Yes, the symmetrical design allows bidirectional rotation and handles reversing loads without issues.What maintenance is required?
No lubrication needed. Periodically inspect the rubber element for wear or damage; replace when necessary.Can I use this coupling in an outdoor environment?
Yes, the rubber is UV-resistant and suitable for -30°C to +80°C. For marine or harsh chemical environments, we recommend our special coating options.What is the typical lead time?
Standard models are usually shipped within 15–25 working days after order confirmation. Customized orders may take longer.
