Hebei Speed Torque Transmission Technology Co., Ltd., established in 2017 with a factory spanning 3,000–5,000 square meters, specializes in the production of high-quality power transmission components. Our FCL Type Elastic Sleeve Pin Coupling with Brake Wheel is engineered for demanding high-torque shaft connections, offering reliable torque transmission combined with integrated braking functionality. This coupling is the ideal solution for applications where space is limited but performance cannot be compromised. With ISO9001 certification and exports to over 15 global markets, we ensure every unit meets international standards of precision and durability.
Key Features & Technical Specifications
Elastic Sleeve Pin Design – The coupling utilizes high-elasticity nylon or polyurethane pin bushes that effectively absorb vibration and shock loads, protecting connected machinery from damage during start-up or sudden load changes.
Integrated Brake Wheel – The brake wheel is machined directly onto the coupling hub, allowing for compact installation of disc brakes. This eliminates the need for separate brake drum adaptors, saving space and reducing overall system weight.
High Torque Capacity – Available in multiple sizes, our FCL coupling can transmit rated torque from 63 Nm up to 31,500 Nm, making it suitable for a wide range of heavy-duty industrial applications.
Customizable Shaft Bores – Standard bore diameters range from 20 mm to 100 mm, with keyways and tolerances according to customer specifications. Non-standard bores can be supplied upon request.
Durable Material & Surface Treatment – Hubs are manufactured from high-strength steel or ductile iron, with optional anti-corrosion coating for harsh environments. The brake wheel surface is hardened for long service life.
Easy Installation & Maintenance – The split hub design (on selected sizes) allows for quick assembly without disturbing the connected equipment. Elastic pins are replaceable, extending the coupling’s overall lifespan.
Technical Parameters (Typical Sizes)
| Model | Rated Torque (Nm) | Brake Wheel Ø (mm) | Max Bore (mm) | Overall Length (mm) |
|---|---|---|---|---|
| FCL-1 | 63 | 160 | 28 | 150 |
| FCL-3 | 315 | 250 | 48 | 215 |
| FCL-5 | 1250 | 400 | 75 | 310 |
| FCL-7 | 8000 | 500 | 90 | 410 |
| FCL-9 | 31500 | 630 | 100 | 530 |
Note: Custom bore sizes, keyway dimensions, and brake wheel width can be adapted to customer requirements. All parameters are for reference; final dimensions depend on specific model and application.
Advantages for Your Application
Space Saving – Combining the coupling and brake wheel into one compact unit reduces axial length and simplifies installation in tight machinery spaces.
Reduced Maintenance – The elastic sleeve pins are easily replaceable without removing the hubs, minimizing downtime during routine inspection.
Enhanced Safety – The brake wheel provides a reliable braking interface for emergency stops or holding loads, critical in hoisting, conveyor, and mining equipment.
Vibration Damping – The elastic elements effectively isolate torsional vibrations, extending the life of both the coupling and the connected shafts/gearboxes.
Cost-Effective – Compared to separate coupling and brake drum assemblies, the integrated design reduces component count, procurement costs, and assembly time.

Frequently Asked Questions (FAQ)
Q1: What is the maximum torque this FCL coupling can handle?
A: The largest model in our standard range (FCL-9) can transmit up to 31,500 Nm. For higher torques, please consult our engineering team for a custom solution.
Q2: Can the brake wheel be used with any disc brake caliper?
A: The brake wheel diameter and width are designed to accommodate common brake calipers. We recommend providing your caliper specifications so we can confirm compatibility or adjust the wheel dimensions.
Q3: Are these couplings suitable for vertical shaft installations?
A: Yes, the FCL coupling can be used in vertical applications. However, we advise using proper axial retention methods (e.g., retaining rings or shaft locks). Please inform us of the orientation during ordering.
Q4: How often should the elastic pins be replaced?
A: The service life depends on operating conditions (torque fluctuations, ambient temperature, alignment). Under normal conditions, the pins may last 12–24 months. We recommend periodic inspection every 6 months.
Q5: Do you offer custom bore sizes or keyways?
A: Absolutely. We can machine bores from 20 mm up to 100 mm (or larger on special request) and supply any keyway standard (metric or inch). Non-standard tolerances are also available upon request.
Q6: What is the standard lead time for an FCL coupling?
A: For standard models, production usually takes 25–35 days after order confirmation. Custom orders may require 35–50 days, depending on complexity.
Q7: Is the coupling supplied with a brake caliper?
A: No, the coupling includes only the brake wheel. Brake calipers must be sourced separately, but we can recommend compatible models based on your braking torque requirements.
Q8: Can the coupling be used in explosive environments (ATEX)?
A: Our standard FCL coupling is not ATEX certified. For hazardous environments, we can offer alternative materials or coatings based on your requirements. Please contact our sales team for a detailed discussion.
