(III) Easy Maintenance
- Simple Friction Pad Replacement: Replacing friction pads is straightforward and doesn't necessitate clutch disassembly, significantly cutting maintenance costs and time, while boosting maintenance efficiency and reducing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: This distinctive design greatly enhances the product's heat dissipation capabilities, effectively lowering operational temperatures, extending product life, and ensuring equipment stability during prolonged, high-load operations.
(V) Quick Response
- Fast Clutching and Braking: With a rapid response rate, it swiftly executes clutching and braking functions, satisfying the swift response needs of various mechanical equipment and enhancing production efficiency.
(VI) Diverse Connection Methods
- Flexible Connection Options: Equipped with multiple connection methods, it offers versatile adaptability to suit different site requirements, ensuring perfect compatibility with a wide range of equipment.


III. Product Structure
The pneumatic clutch brake is primarily composed of the following elements:
- Clutch Body: Mounted on the equipment's main shaft, the center hole size can be customized according to customer specifications (size range available in the sample), serving as the clutch's core component.
- Clutch Ear Plate and Brake Ear Plate: These components are seamlessly connected to the flywheel and machine body of the equipment through four sturdy pins. This configuration assures the smooth and reliable operation of the clutch and brake mechanisms.
- Friction Pads (Blocks): Integral to the clutching and braking processes, these pads are responsible for the seamless transmission and interruption of power, playing an essential role in the system's functionality.
- Clutch Pins, Brake Pins, and Locking Plates: Vital for connecting and securing various components, the locking plates are ingeniously embedded in the pin grooves and 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 enters the clutch cylinder through the intake hole, propelling the piston into action. This movement, through the friction pads, clutch body, and flat key, rotates the driven part to achieve clutch engagement, thus facilitating the seamless transmission of power.

(II) Braking Process
Upon halting the air supply, the piston is urged in the reverse direction by the spring's force. Through the friction pads, clutch body, and flat key, the driven part is rapidly braked. With an astonishingly swift braking time of just 0.01 - 0.02 seconds, the equipment can be promptly and effectively stopped, ensuring precision and safety.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
The installation of the four pins demands a hole tolerance of H7, and the hole center must be precisely parallel to the main shaft center. This ensures the utmost accuracy and stability in the installation of the pins, contributing to overall system reliability.

(II) Geometric Tolerance and Roughness Requirements
Strict adherence to national standards for the geometric tolerance and roughness of the center hole and keyway is imperative. Similarly, the main shaft's geometric tolerance and roughness must meet corresponding benchmarks to enhance the product's performance and ensure optimal operation.

(III) Installation Sequence Suggestions
Installation sequence flexibility is offered to customers depending on varying circumstances. Typically, the installation begins with the clutch and brake ear plates, followed by the pins and locking plates, culminating in the assembly of the clutch brake body.

(IV) Installation Notes for Square Pins
Square pins are expertly utilized to counteract installation size discrepancies between two pins and mitigate plate thermal deformation due to clutch heating. It is crucial to ensure the two flat surfaces of the square pin remain parallel to the radial direction of the ear plate for optimal function.

(V) Sealing Requirements for Axial Air Intake
For axial air intake systems, it is essential to securely install sealing caps at both ends of the clutch to effectively prevent any gas leakage, thereby maintaining system integrity.

(VI) Check after Installation
A thorough post-installation inspection should confirm that the clutch end and brake end can move freely. This ensures the smooth and efficient operation of the clutch and brake systems, safeguarding their longevity and performance.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every clutch we distribute undergoes rigorous quality checks. Customers must refrain from privately disassembling the clutch, as any damage from such actions will void our responsibility. Should any quality issues arise, promptly notify us, and we promise a swift resolution.

(II) Friction Pad Replacement Method
Friction pads are wear parts and require replacement after extended use. Our friction pads are designed for easy replacement without dismantling the ear plates or clutch. Here's how to replace them:
- Replacement without Air Supply: Simply loosen the clutch ear plate, remove the securing bolts and nuts, swap in new friction pads, and retighten the fasteners.
- Replacement with Air Supply: Follow the same procedure by loosening the brake ear plate, ensuring seamless replacement of the friction pads.

(III) Timing for Friction Pad Replacement
- On machinery like presses, if performance dips below rated capacity, inspect the friction pads for necessary replacement.
- If friction pad wear exceeds half of their original thickness, timely replacement is essential for optimal performance.

VII. Product Selection
Selecting the right clutch for your equipment is vital for optimal performance and efficiency.
- Consequences of Improper Selection: A clutch too small won't satisfy capacity needs; too large will inflate costs and potentially overheat, hastening wear and sealing ring aging.
- Selection Suggestions: Refer to our comprehensive samples or consult with our expert technicians for tailored, professional guidance.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
Never make contact with the clutch with hands or objects during high-speed rotation to prevent accidents.

(II) Protection from High Temperature
Avoid direct contact with the clutch immediately after operation to prevent burns. Allow approximately 30 minutes for cooling before maintenance.

(III) Side Protection
Standing beside a spinning clutch is hazardous due to potential debris. Always use a protective cover during operation.

(IV) Attention during Ventilation Operation
During ventilation and air shut-off, refrain from touching the friction pads to avoid injury from pinching.

(V) Safety of Internal Structure
The clutch contains internal springs; unauthorized disassembly can result in injury. Disassembly should only be performed by qualified professionals.
