A tyre coupling is a flexible shaft coupling designed to transmit torque while accommodating misalignment between connected shafts. It consists of a flexible elastomeric element, often reinforced with cords or fabric, which is clamped between two hubs. This design allows for angular, parallel, and axial misalignments, while also providing vibration damping and shock absorption. Tyre couplings are commonly used in various industrial applications, such as pumps, compressors, generators, and conveyors, due to their durability and ease of maintenance.
Below is a detailed table outlining the standard parameters for our tyre coupling models. These specifications are based on industry standards and can be tailored to specific requirements.

|---|---|---|---|---|---|
| TC-100 | 10-50 | 150 | 5000 | 1.2 | Nitrile Rubber, Steel Hubs |
| TC-200 | 20-80 | 500 | 4000 | 3.5 | Neoprene, Cast Iron Hubs |
| TC-300 | 30-100 | 1200 | 3500 | 7.8 | Polyurethane, Stainless Steel Hubs |
| TC-400 | 40-120 | 2500 | 3000 | 12.0 | Natural Rubber, Aluminum Hubs |
| TC-500 | 50-150 | 4000 | 2500 | 18.5 | EPDM Rubber, Ductile Iron Hubs |
Tyre couplings are versatile and used across multiple industries. Common applications include:
Proper installation is crucial for optimal performance. Follow these steps:
For maintenance, regularly inspect the tyre element for cracks, wear, or degradation. Replace if any signs of damage are detected. No lubrication is needed, but keep the coupling clean from debris.
What is the primary function of a tyre coupling?
The primary function is to transmit torque between two shafts while accommodating misalignment and providing vibration damping.
How does a tyre coupling handle misalignment?
It uses a flexible elastomeric element that can bend and twist, allowing for angular, parallel, and axial misalignments without transmitting excessive forces to the connected equipment.
What materials are commonly used in tyre couplings?
Common materials include nitrile rubber, neoprene, polyurethane, and natural rubber for the flexible element, with hubs made from steel, cast iron, stainless steel, or aluminum.
Are tyre couplings suitable for high-speed applications?
Yes, many models are designed for high speeds, but it's essential to check the maximum RPM specification for each model to ensure suitability.
How often should I inspect a tyre coupling?
Inspect every 3 to 6 months under normal operating conditions, or more frequently in harsh environments or high-load applications.
Can tyre couplings be used in outdoor or corrosive environments?
Yes, with appropriate material selection, such as EPDM rubber for weather resistance or stainless steel hubs for corrosion resistance, they can perform well in challenging conditions.
What is the typical lifespan of a tyre coupling?
Lifespan varies based on usage, but with proper maintenance, they can last several years. Factors like load, speed, and environment affect durability.
Do tyre couplings require balancing?
They are generally self-balancing due to their symmetrical design, but for high-precision applications, dynamic balancing might be recommended during manufacturing.
Can I replace just the tyre element without changing the hubs?
Yes, in most designs, the tyre element can be replaced separately, which reduces downtime and maintenance costs.
What are the signs that a tyre coupling needs replacement?
Signs include visible cracks, excessive wear, hardening of the rubber, loss of flexibility, unusual noises, or increased vibration during operation.
