Our clutch brake product finds widespread application across diverse sectors like forging, printing, textile, welding, and shipbuilding. It garners particular acclaim in areas such as metal processing, paper processing machinery, woodworking machinery, and fiber machinery, consistently delivering high performance.

II. Product Advantages
(I) Compact Structure
- Minimal Axial Size and Lightweight: With a minimal axial size and lightweight design, it boasts low inherent rotational inertia, effectively reducing the overall dimensions and weight without compromising performance. This results in enhanced operational efficiency of the equipment.
(II) Safe and Reliable
- Asbestos-Free Friction Material: Utilizing friction material devoid of asbestos, it eliminates asbestos-related health risks, aligning with modern safety and environmental standards. This offers a safer, more reliable user experience.
(III) Easy Maintenance
- Simplified Friction Pad Replacement: The friction pads are easily replaceable without dismantling the clutch, significantly cutting maintenance costs and time. This boosts maintenance efficiency and minimizes equipment downtime.
(IV) Outstanding Heat Dissipation Performance
- Distinctive Disc Arc Design: The unique disc arc design substantially enhances heat dissipation, efficiently reducing operational temperatures, prolonging product lifespan, and ensuring equipment stability during prolonged high-load operations.
(V) Quick Response
- Swift Clutching and Braking: With a remarkably fast response rate, it seamlessly executes clutching and braking functions, catering to the quick response needs of various mechanical equipment, thus elevating production efficiency.
(VI) Versatile Connection Methods
- Adaptive Connection Options: Equipped with multiple connection methods, it offers flexibility to suit diverse site requirements, showcasing strong adaptability and perfect compatibility with a wide range of equipment.


III. Product Structure
The pneumatic clutch brake is predominantly composed of these key components:
- Clutch Body: Mounted on the equipment's main shaft, the center hole size is customizable to meet client specifications (refer to sample for size range). It stands as the pivotal component of the clutch system.
- Clutch Ear Plate and Brake Ear Plate: These essential components are intricately connected to the flywheel and the machine body of the equipment through four robust pins. This strategic connection guarantees the smooth and stable operation of both the clutch and brake systems, offering unmatched reliability in performance.
- Friction Pads (Blocks): As pivotal elements in the clutching and braking process, these friction pads masterfully manage the transmission and interruption of power, ensuring seamless and efficient operation.
- Clutch Pins, Brake Pins, and Locking Plates: These crucial components are meticulously utilized for the connection and fixation of various parts. Notably, the locking plates, ingeniously embedded in the pin grooves, are securely fastened to the flywheel or machine body with screws, effectively preventing any unwanted axial movement of the pins.


IV. Working Principle
(I) Clutching Process
External compressed air is expertly directed into the clutch cylinder via the intake hole, propelling the piston into motion. Through the collaborative effort of the friction pads, clutch body, and flat key, the driven part engages in rotation, achieving clutch engagement and facilitating the transmission of power with remarkable efficiency.

(II) Braking Process
Upon cessation of the air supply, the piston is ingeniously driven in the opposite direction by the spring's action. This reverse motion, together with the friction pads, clutch body, and flat key, rapidly brakes the driven part. The swift braking time, a mere 0.01 - 0.02 seconds, ensures the equipment halts almost instantaneously, providing exceptional control and safety.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
For optimal installation precision and stability of the pins, the hole tolerance for the installation of the four pins should adhere to H7 standards. Additionally, ensuring that the hole center remains parallel to the main shaft center is crucial for maintaining superior installation accuracy.

(II) Geometric Tolerance and Roughness Requirements
The geometric tolerance and roughness specifications for the center hole and keyway must strictly align with national standards. Moreover, the geometric tolerance and roughness of the customer's main shaft are equally critical and must satisfy the corresponding criteria to enhance overall product performance.

(III) Installation Sequence Suggestions
Customers are encouraged to tailor the installation sequence to their specific circumstances. Typically, the recommended order begins with the installation of the clutch and brake ear plates, followed by the pins and locking plates, culminating with the installation of the clutch brake body for optimal integration.

(IV) Installation Notes for Square Pins
Square pins play a vital role in compensating for size discrepancies during installation and addressing plate thermal deformation induced by clutch heating. It is imperative that the two flat surfaces of the square pin maintain parallel alignment with the radial direction of the ear plate for precision installation.

(V) Sealing Requirements for Axial Air Intake
For an axial air intake configuration, it is essential to install sealing caps at both ends of the clutch. This precautionary measure effectively prevents gas leakage, ensuring optimal performance.

(VI) Check after Installation
Following installation, it is critical to verify that both the clutch end and brake end move without obstruction, ensuring the flawless operation of the clutch and brake systems, and safeguarding their long-term reliability.

VI. Product Maintenance
(I) Expert Maintenance Recommendations
To ensure the longevity and optimal performance of each clutch, every unit has been rigorously tested and approved before reaching your hands. Please refrain from unauthorized disassembly, as it may void the warranty and we cannot be held accountable for damages incurred. Should you encounter any quality issues, promptly contact us, and our team will swiftly resolve them.

(II) Method for Replacing Friction Pads
Friction pads are crucial consumables that need replacement after prolonged use when they become significantly worn. Our innovative design streamlines the replacement process, eliminating the need to disassemble ear plates or the clutch itself. Here's the straightforward procedure:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Unfasten the bolts and nuts securing the worn friction pads, swap them with new ones, and securely retighten the bolts and nuts.
- Replacement with Air Supply: Similarly, loosen the brake ear plate, then follow the aforementioned steps to install the new friction pads.

(III) Optimal Timing for Friction Pad Replacement
- On equipment like presses, if the machine fails to deliver its rated capacity, inspect the friction pads for replacement.
- Should the wear on the friction pads exceed half their original thickness, timely replacement is advised to maintain peak performance.

VII. Product Selection
Choosing the right clutch is paramount to the efficiency and safety of your equipment.
- Risks of Incorrect Selection: A clutch that's too small will not suffice in meeting the rated capacity, while an oversized one unnecessarily elevates costs and risks overheating, expediting wear on friction pads and seal aging.
- Selection Guidance: Our comprehensive product samples and expert consultation services are readily available to assist you in making informed decisions. Let our specialists guide you to the perfect clutch choice for your needs.

VIII. Safety Precautions
(I) High-Speed Rotation Safety Measures
For your safety, never come into contact with the clutch or allow objects near it during high-speed rotation to prevent hazardous situations.

(II) Heat Protection Protocols
After the clutch has ceased rotating, it remains hot. Avoid direct contact for at least half an hour, allowing it to return to room temperature to prevent burns.

(III) Lateral Safety Measures
Always avoid standing beside the rotating clutch to mitigate risks from any potential projectiles. Ensure a protective cover is in place during operation.

(IV) Ventilation Operation Cautions
During air supply changes, keep fingers clear of friction pads to avoid accidental pinching.

(V) Internal Structure Safety
The clutch contains delicate internal springs. Unauthorized disassembly is hazardous and should only be performed by trained professionals to avoid injuries.
