A tyre coupling is a flexible coupling designed to transmit torque between two shafts while accommodating misalignment, reducing vibration, and absorbing shock loads. It consists of a flexible elastomeric element, often shaped like a tyre, which is bolted between two hubs connected to the shaft ends. This design allows for angular, parallel, and axial misalignments, making it ideal for various industrial applications where flexibility and durability are required. Tyre couplings are known for their high torsional flexibility, electrical insulation properties, and ability to operate in harsh environments without lubrication.
Our tyre couplings are manufactured to meet international standards, ensuring reliability and performance. Below is a detailed table of specifications for our standard product range.

Tyre couplings are widely used in industries that require reliable power transmission with flexibility. Common applications include:
Compared to rigid or gear couplings, tyre couplings offer several benefits:
Proper installation ensures optimal performance and longevity. Follow these steps:
Maintenance involves regular visual inspections for wear, cracks, or degradation of the elastomer. Replace the tyre element if any damage is detected, typically every 1-5 years depending on operating conditions.
What is the maximum misalignment a tyre coupling can handle?
Tyre couplings can typically accommodate up to 3 degrees angular misalignment, 2 mm parallel misalignment, and ±2 mm axial displacement, depending on the size and model. Always refer to the product specifications for exact values.
How do I select the right tyre coupling for my application?
Consider factors such as torque requirements, shaft sizes, operating speed, misalignment types, and environmental conditions (e.g., temperature, exposure to chemicals). Use the rated torque and bore diameter from our specification table to match your needs, and consult with our engineering team for custom applications.
Are tyre couplings suitable for high-temperature environments?
Yes, our tyre couplings are designed to operate in temperatures from -50°C to +100°C. For higher temperatures, special elastomer materials can be used upon request.
Do tyre couplings require balancing?
Standard tyre couplings are dynamically balanced during manufacturing for smooth operation at high speeds. However, in precision applications, additional balancing might be necessary after installation.
Can I replace the tyre element without disassembling the entire coupling?
Yes, the flexible tyre element can be replaced without removing the hubs from the shafts, minimizing downtime. Simply unbolt the old element and install the new one, ensuring proper alignment.
What are the signs that a tyre coupling needs replacement?
Look for visible cracks, hardening or softening of the elastomer, excessive wear, or increased vibration and noise during operation. Regular inspections help identify these issues early.
Is electrical insulation a standard feature?
Yes, the elastomeric material provides inherent electrical insulation, preventing current flow between shafts and reducing the risk of galvanic corrosion in mixed-metal systems.
How does a tyre coupling compare to a jaw coupling in terms of performance?
Tyre couplings offer higher misalignment capacity and better shock absorption than jaw couplings, but jaw couplings might be more compact and suitable for lower torque applications. The choice depends on specific operational needs.
