Hebei Speed Torque Transmission Technology Co., Ltd., established in 2017 with a factory spanning 3,000–5,000 square meters and a dedicated team of 101–200 employees, proudly introduces our Flexible Rubber Tyre Coupling Taper Lock Shaft Connector. Designed specifically for conveyor production lines, this coupling delivers exceptional misalignment compensation, vibration dampening, and shock absorption – ensuring smooth and reliable power transmission even in demanding industrial environments. Our annual export value of US$5–10 million reflects global trust in our engineering excellence and manufacturing precision.
This coupling features a robust natural rubber tyre element combined with a precision-machined cast iron or alloy steel hub, equipped with a taper lock bush system for quick and secure shaft connection. Whether you need to connect a motor to a conveyor roller or a gearbox to a production line drive, our flexible tyre coupling minimizes downtime and maintenance while maximizing equipment lifespan. Backed by ISO9001:2015 certification, every unit undergoes rigorous quality control to meet international standards.
Below are the key technical specifications and performance parameters for our standard models. Custom sizes and configurations are available upon request to suit your specific conveyor system requirements.
| Parameter | Value / Range |
|---|---|
| Nominal Torque | 50 Nm – 5000 Nm (model dependent) |
| Bore Diameter | 10 mm – 100 mm (custom up to 200 mm) |
| Maximum Speed | 3000 rpm (depending on size and balance) |
| Misalignment Capacity | Radial: ±1.5 mm, Angular: 1°, Axial: ±2 mm |
| Operating Temperature | -20°C to +80°C (higher temp rubber optional) |
| Material | Natural rubber tyre / Cast iron hub (or alloy steel) |
| Taper Lock Bush Size | 1008 – 4040 (interchangeable industry standard) |
Key Features & Benefits
- Flexible rubber tyre element – absorbs vibration and shock loads, protecting connected equipment like motors and gearboxes from premature failure.
- Taper lock shaft connection – eliminates keyway backlash and provides a concentric, zero-maintenance fit. Easy to install and remove without damaging shafts.
- High misalignment tolerance – compensates for angular, parallel, and axial misalignments common in conveyor installations, reducing downtime for realignment.
- Broad torque range – suitable for light duty (e.g., small conveyors) to heavy duty (e.g., bulk material handling) applications.
- Durable construction – cast iron hubs resist corrosion and wear; natural rubber tyre is resistant to oil, weather, and aging (EPDM option available).
- Low maintenance – no lubrication required; the rubber element can be replaced individually, extending coupling life.
- Customizable bore and keyway – we can machine to your exact shaft dimensions, taper lock size, and metric or inch keyways.
- ISO9001:2015 certified factory – consistent quality with full traceability and inspection reports available.
Ideal Applications
Our flexible rubber tyre coupling with taper lock is widely used in:
- Conveyor belt drive systems (assembly lines, packaging, mining, food processing)
- Production line machinery (mixers, agitators, pumps, fans)
- Heavy equipment such as crushers, mills, and presses where shock loads are present
- Agricultural machinery, chemical plants, and steel mills
The coupling’s design inherently acts as a fuse – if overloaded, the rubber tyre tears instead of damaging expensive shafts or components. Replacement of the tyre is quick and cost-effective, minimizing production stoppages.
Why Choose Hebei Speed Torque Transmission Technology Co., Ltd.?

Frequently Asked Questions
Q1: What makes a tyre coupling different from a jaw coupling?
A tyre coupling uses a rubber tyre that completely surrounds the hubs, providing greater vibration damping and higher misalignment capacity than a standard jaw coupling. It is ideal for heavy shock loads and applications where maintenance access is limited.
Q2: How does the taper lock system work?
The taper lock consists of a tapered sleeve and a matching tapered bore in the hub. Tightening the screws pulls the sleeve inward, clamping the shaft evenly without damaging it. Removal is achieved by loosening the screws and using the jacking screws to separate the sleeve from the hub.
Q3: Can I use this coupling in a high-temperature environment?
Standard natural rubber is rated for -20°C to +80°C. For higher temperatures, we offer optional EPDM or silicone rubber elements that can withstand up to +150°C. Please specify your operating temperature when ordering.
Q4: Do you provide custom bore sizes and keyways?
Yes, we can machine the hubs to any bore diameter and keyway configuration (metric or inch). Just provide your shaft dimensions and desired tolerance (e.g., H7 or K6).
Q5: Is the rubber tyre replaceable?
Absolutely. The tyre is designed to be replaced individually without removing the hubs from the shafts. This reduces downtime – simply unbolt the flanges, slide off the old tyre, and install a new one.
Q6: What is the recommended maintenance interval?
No lubrication is required. Inspect the tyre periodically for cracks, wear, or deformation – typically every 6–12 months depending on load cycles. Replace the tyre if any damage is visible.
Q7: How can I determine the correct coupling size for my conveyor?
We need the following: motor power (kW), shaft diameters, speed (RPM), and application type (light/medium/heavy duty). Our sales engineers can calculate the required torque and select the appropriate model. We also provide selection software upon request.
Q8: Do you offer sample testing before bulk order?
Yes, we can produce a sample coupling matching your specifications for on-site testing. After approval, we can proceed with mass production with consistent quality. Sample cost is negotiable and often refundable for large orders.
