(I) Application Fields
This product is a preferred choice across a spectrum of industries, including forging, printing, textile, welding, and shipbuilding. It garners exceptional acclaim in metal processing, paper processing machinery, woodworking machinery, and fiber machinery sectors.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Light Weight: With a minimalist axial size and lightweight structure, it boasts low inherent rotational inertia. This configuration effectively reduces both the volume and weight of the equipment, enhancing performance and boosting operational efficiency.
(II) Safe and Reliable
- Asbestos-free Friction Material: The absence of asbestos in the friction material eliminates potential health risks, aligning with contemporary environmental and safety standards, and offering users a secure and trustworthy experience.
(III) Easy Maintenance
- Simple Friction Pad Replacement: Easily replaceable friction pads without disassembling the clutch drastically cut down on maintenance costs and time, augmenting maintenance efficiency while minimizing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: This pioneering disc arc design massively enhances the heat dissipation capacity, effectively managing operational temperatures, prolonging product lifespan, and maintaining equipment stability during prolonged high-load operations.
(V) Quick Response
- Fast Clutching and Braking: With a swift response rate, it adeptly executes clutching and braking operations, fulfilling the rapid response demands of various mechanical equipment, thereby elevating production efficiency.
(VI) Diverse Connection Methods
- Flexible Connection Options: Offering a plethora of connection methods adaptable to diverse site requirements, it showcases strong adaptability, ensuring perfect compatibility with a wide array of equipment.


III. Product Structure
The pneumatic clutch brake is ingeniously crafted from the following key components:
- Clutch Body: Securely mounted on the equipment's main shaft. Its center hole size can be customized to meet client specifications (refer to the sample for size range), serving as the pivotal component of the clutch.
- Clutch Ear Plate and Brake Ear Plate: These components are ingeniously connected to the flywheel and the machine body through four sturdy pins, ensuring unwavering stability and seamless operation of the clutch and brake systems.
- Friction Pads (Blocks): These essential components are pivotal in the clutch and braking mechanisms, facilitating the seamless transmission and interruption of power, ensuring precision and efficiency.
- Clutch Pins, Brake Pins, and Locking Plates: These elements are crucial for the secure connection and fixation of various components. Notably, the locking plates are meticulously embedded within the pin grooves and firmly affixed to the flywheel or machine body with screws, preventing any unwanted axial pin movement.


IV. Working Principle
(I) Clutching Process
External compressed air dynamically enters the clutch cylinder via the intake hole, propelling the piston into action. Through the integrated friction pads, clutch body, and flat key, the driven components engage in rotation, achieving seamless clutch engagement and power transmission.

(II) Braking Process
Upon cessation of air supply, the piston swiftly reverses direction under the spring's influence. Through the friction pads, clutch body, and flat key, the driven part is promptly halted within a mere 0.01 to 0.02 seconds, ensuring rapid stoppage and safety for the equipment.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Ensure precision by maintaining a hole tolerance of H7 during the installation of the four pins. The hole center must align parallel to the main shaft center, guaranteeing optimal installation accuracy and pin stability.

(II) Geometric Tolerance and Roughness Requirements
Adhering to stringent national standards, the geometric tolerance and roughness of the center hole and keyway are essential. Correspondingly, the customer's main shaft must meet these precise requirements to enhance product performance and efficiency.

(III) Installation Sequence Suggestions
Customers have the flexibility to choose the installation sequence based on specific conditions. Typically, install the clutch and brake ear plates, followed by pins and locking plates, and finally, the clutch brake body for optimal efficiency.

(IV) Installation Notes for Square Pins
Square pins are strategically employed to counteract installation size discrepancies of two pins and the thermal deformation of plates due to clutch heating. It is crucial to ensure that the two flat surfaces of the square pin remain parallel to the radial direction of the ear plate.

(V) Sealing Requirements for Axial Air Intake
For axial air intake mechanisms, it is imperative to install sealing caps at both ends of the clutch to effectively prevent any potential gas leakage, ensuring optimal operational integrity.

(VI) Check after Installation
Post-installation, ensure that the clutch end and brake end can move freely and without hindrance, thereby guaranteeing the smooth and effective operation of both the clutch and brake mechanisms.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every clutch we offer has passed through a rigorous quality assurance process. Customers are advised against unauthorized disassembly. Should any issues arise from unauthorized tampering, our company cannot be held liable. In the event of any quality issues, please notify us promptly, and we will address them swiftly.

(II) Friction Pad Replacement Method
The friction pads are essential consumables, requiring replacement after prolonged use when they show significant wear. Our design allows for easy replacement of friction pads without needing to disassemble the ear plates or clutch. Here's how you can effortlessly replace them:
- Replacement without Air Supply: Simply loosen the clutch ear plate, unscrew the bolts and nuts securing the friction pads, insert new pads, and then retighten the bolts and nuts securely.
- Replacement with Air Supply: Loosen the brake ear plate and follow the same straightforward steps to swap in new friction pads.

(III) Timing for Friction Pad Replacement
- For machines like presses, if they fail to achieve rated capacity, inspect the friction pads for potential replacement needs.
- Replace the friction pads promptly when their wear exceeds 50% of the original thickness.

VII. Product Selection
Choosing the right clutch is pivotal for optimal performance in your equipment.
- Consequences of Improper Selection: A clutch too small won't meet capacity demands; one too large will hike equipment costs, cause overheating, accelerated friction pad wear, and hasten the aging of sealing rings.
- Selection Suggestions: Opt from our extensive range of samples, or consult our expert technicians for tailored advice. We are eager to provide you with the most suitable clutch solutions.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
Never touch the clutch, either by hand or with objects, while it's in high-speed rotation to prevent potential hazards.

(II) Protection from High Temperature
Avoid direct contact with the clutch immediately after use to prevent burns. Allow at least 30 minutes for the clutch to cool to room temperature before conducting any maintenance.

(III) Side Protection
To mitigate risks from debris, always avoid standing beside a rotating clutch. Employ a protective cover during operation for safety.

(IV) Attention during Ventilation Operation
During ventilation operations, keep fingers away from the friction pads to avoid injury.

(V) Safety of Internal Structure
The clutch contains internal springs. Unauthorized disassembly is dangerous. If necessary, only qualified professionals should perform the task to ensure safety.
