This versatile product finds its place in diverse industries such as forging, printing, textiles, welding, and shipbuilding. It has earned acclaim, particularly in sectors like metal processing, paper processing machinery, woodworking machinery, and fiber machinery.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Light Weight: It features a minimal axial size and reduced weight, with low inherent rotational inertia, substantially minimizing the equipment's overall size and weight while preserving performance, thereby enhancing operational efficiency.
(II) Safe and Reliable
- Asbestos-free Friction Material: The product utilizes friction materials devoid of asbestos, circumventing the health hazards associated with asbestos, aligning with contemporary environmental and safety standards and affording users a safer, more reliable experience.
(III) Easy Maintenance
- Simplified Friction Pad Replacement: The ease of friction pad replacement without clutch disassembly significantly trims maintenance costs and time, boosts maintenance efficiency, and curtails equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: Our distinct disc arc design markedly amplifies heat dissipation capabilities, effectively lowering operational temperatures, prolonging product lifespan, and ensuring machinery stability during extended high-load operations.
(V) Quick Response
- Rapid Clutching and Braking: With a swift response time, it provides rapid clutching and braking capabilities, satisfying the demands of various mechanical equipment for quick response, thereby boosting production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Equipped with a plethora of connection methods, it offers flexible selection based on site-specific demands, exhibiting remarkable adaptability and ensuring impeccable compatibility with diverse equipment.


III. Product Structure
The pneumatic clutch brake is intricately composed of the following essential components:
- Clutch Body: Anchored on the main shaft of the device, its center hole size is customizable to meet customer specifications (refer to the sample for size range), serving as the pivotal element of the clutch system.
- Clutch Ear Plate and Brake Ear Plate: Ingeniously linked to the flywheel and machine body via four well-positioned pins, these components guarantee the seamless and stable operation of both the clutch and brake mechanisms, enhancing overall equipment reliability.
- Friction Pads (Blocks): These critical elements act as the heart of the clutching and braking system, expertly managing the transition and interruption of power flow with precision and efficiency.
- Clutch Pins, Brake Pins and Locking Plates: Crafted for robust connection and secure fixation of various components, the locking plates are cleverly embedded within pin grooves and securely fastened to the flywheel or machine body with screws, effectively preventing any axial movement of the pins.


IV. Working Principle
(I) Clutching Process
External compressed air enters the clutch cylinder through the strategically designed intake hole, propelling the piston into motion. Harnessing the power of friction pads, clutch body, and flat key, this movement enables the driven part to rotate and engage, facilitating a smooth transmission of power.

(II) Braking Process
Once the air supply is halted, the piston, assisted by spring action, shifts in the reverse direction. Utilizing friction pads, clutch body, and flat key, this swift action ensures the driven part is rapidly braked, with a reaction time of merely 0.01 - 0.02 seconds, ensuring quick and efficient equipment stoppage.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
For optimal installation precision and stability, the hole tolerance for the four pins should be H7, while maintaining hole center parallelism with the main shaft center.

(II) Geometric Tolerance and Roughness Requirements
Strict adherence to national standards for geometric tolerance and roughness of the center hole and keyway is essential. The customer's main shaft must also meet relevant criteria to ensure elevated product performance.

(III) Installation Sequence Suggestions
Flexibility in installation sequence is provided, allowing customization based on specific needs. Typically, installation begins with the clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body.

(IV) Installation Notes for Square Pins
Square pins are expertly designed to compensate for installation size discrepancies between two pins and mitigate plate thermal deformation from clutch heating. Ensure the flat surfaces of square pins maintain parallel alignment with the radial direction of the ear plate for optimal performance.

(V) Sealing Requirements for Axial Air Intake
For axial air intake scenarios, it is crucial to install sealing caps at both ends of the clutch to effectively prevent any gas leakage, ensuring efficient operation.

(VI) Check after Installation
Conduct a thorough post-installation check to confirm that both the clutch end and brake end move freely, guaranteeing the clutch and brake function as intended for reliable operation.

Product Description

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Our clutches undergo rigorous quality control before reaching you. Please refrain from dismantling the clutch without professional assistance, as our warranty does not cover damages from unauthorized disassembly. Should you encounter any issues with product quality, notify us promptly, and we will address your concerns swiftly and efficiently.

(II) Friction Pad Replacement Method
Friction pads are essential yet consumable, requiring replacement after extensive use. Our design simplifies this process—no need to remove the ear plates or disassemble the clutch. Here's how to replace them:
- Replacement without Air Supply: Simply loosen the clutch ear plate, remove and replace the bolts and nuts with ease, ensuring you secure the new friction pads properly.
- Replacement with Air Supply: Follow similar steps by loosening the brake ear plate, swapping out the old pads for new ones in a few easy steps.

(III) Timing for Friction Pad Replacement
- Unable to achieve full machine capacity? It might be time to inspect and replace worn-out friction pads.
- Once the wear on your friction pads surpasses half of their original state, immediate replacement is essential to maintain optimal performance.

VII. Product Selection
Selecting the right clutch is pivotal for the optimal performance of your machinery.
- Consequences of Improper Selection: A misfit clutch can fall short of operational needs, while an oversized one escalates costs and risks, leading to overheating, rapid wear on friction pads, and premature aging of sealing rings.
- Selection Suggestions: Peruse our detailed sample range or consult with our expert technicians, who are ready to guide you with tailored, professional advice to ensure the ideal choice.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
For your safety, never make contact with a clutch in motion. This precaution is vital to prevent hazardous incidents.

(II) Protection from High Temperature
Post-operation, allow a cooling period of approximately 30 minutes before any maintenance to avoid burns from residual heat.

(III) Side Protection
Standing beside a rotating clutch is hazardous—install a protective cover to mitigate risks from potential flying debris.

(IV) Attention during Ventilation Operation
Exercise caution during ventilation operations. Avoid direct contact with moving friction pads to prevent injury.

(V) Safety of Internal Structure
Our clutches contain internal springs. To avoid injury, refrain from unauthorized disassembly. Any required work should be performed by trained professionals only.
