(I) Application Fields
This versatile product finds its place in numerous industries, including forging, printing, textile, welding, and shipbuilding, earning accolades especially in metal processing, paper processing machinery, woodworking machinery, and fiber machinery sectors.

II. Product Advantages
(I) Compact Structure
- Minimal Axial Size and Weight: Featuring a diminutive axial size and lightweight design, our product reduces rotational inertia, compacting the overall equipment dimensions and mass while maintaining stellar performance, thus enhancing operational efficiency.
(II) Safe and Reliable
- Asbestos-Free Friction Material: Composed of asbestos-free friction materials, it eliminates the health risks associated with asbestos, aligning with contemporary environmental and safety standards to provide users with a secure and trustworthy experience.
(III) Easy Maintenance
- Effortless Friction Pad Replacement: Substituting friction pads is straightforward and doesn't necessitate disassembling the clutch—cutting down maintenance costs and time, boosting equipment maintenance efficacy, and reducing downtime.
(IV) Excellent Heat Dissipation Performance
- Innovative Disc Arc Design: The tailored disc arc design dramatically enhances heat dissipation, reducing operational temperatures, prolonging product lifespan, and ensuring equipment stability even during extended high-load operations.
(V) Quick Response
- Swift Clutching and Braking: Its rapid response rate enables quick clutching and braking functions, catering to the fast-paced requirements of various mechanical equipment and boosting production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Equipped with a multitude of connection methods, it can be adapted flexibly to different site needs, demonstrating remarkable compatibility with a wide range of equipment.


III. Product Structure
The pneumatic clutch brake is primarily composed of the following essential components:
- Clutch Body: Mounted on the main shaft of the equipment, its center hole size is customizable according to client specifications (size range available in the sample) and serves as the pivotal component of the clutch.
- Clutch Ear Plate and Brake Ear Plate: Seamlessly interfaced with the flywheel and machine body via four robust pins, providing unwavering stability for both clutch and brake functions.
- Friction Pads (Blocks): Serve as the pivotal force in the clutching and braking process, adeptly managing the seamless transmission and interruption of power.
- Clutch Pins, Brake Pins, and Locking Plates: Essential for the secure connection and fixation of components. The locking plates are precisely embedded in pin grooves and anchored onto the flywheel or machine body with screws, effectively preventing any axial displacement.


IV. Working Principle
(I) Clutching Process
External compressed air is channeled into the clutch cylinder via the intake hole, propelling the piston forward. This action, mediated through the friction pads, clutch body, and flat key, initiates the rotation of the driven part, seamlessly engaging the clutch to transmit power.

(II) Braking Process
Once the air supply ceases, the piston retracts under spring force. Through the friction pads, clutch body, and flat key, the driven part rapidly decelerates. With a braking interval of just 0.01 - 0.02 seconds, the equipment ensures swift cessation.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Ensure the hole tolerance for the four pins is H7, with the hole center perfectly aligned parallel to the main shaft center. This guarantees precision and stability in pin installation.

(II) Geometric Tolerance and Roughness Requirements
Adherence to national standards for geometric tolerance and roughness of the center hole and keyway is crucial. The customer's main shaft must meet these exacting standards to uphold product excellence.

(III) Installation Sequence Suggestions
Depending on specific conditions, customers may adjust the installation sequence. A recommended approach is to initially set up 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 integral to counteract installation size discrepancies between two pins and thermal deformation from clutch heating. It is critical that the flat surfaces of the square pin align parallel to the radial direction of the ear plate.

(V) Sealing Requirements for Axial Air Intake
In cases of axial air intake, it is vital to install sealing caps on each end of the clutch to avert any gas leakage.

(VI) Check after Installation
Post-installation, ensure the clutch and brake ends operate with unrestricted freedom to verify the optimal functioning of the system.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each clutch we sell undergoes rigorous, high-standard quality testing. Customers should refrain from unauthorized disassembly to maintain warranty coverage. Our liability does not extend to damage from such actions. Should you notice any quality issues, please notify us promptly, and we will address them with utmost priority.

(II) Friction Pad Replacement Method
Friction pads are essential wear components; their replacement becomes necessary after prolonged use and noticeable wear. Fortunately, our friction pad replacement process is streamlined and user-friendly, requiring no disassembly of the ear plates or the clutch itself. Follow these straightforward steps:
- Replacement without Air Supply: Start by loosening the clutch ear plate, then remove the bolts and nuts securing the friction pads. Swap them with new pads, ensuring a secure fit by tightening the bolts and nuts.
- Replacement with Air Supply: Begin by loosening the brake ear plate. Replicate the previously mentioned steps to efficiently replace the friction pads.

(III) Timing for Friction Pad Replacement
- For machinery such as presses, if the machine struggles to reach its rated capacity, it may indicate the need for new friction pads.
- When friction pad wear exceeds 50% of their original thickness, timely replacement is advised to maintain optimal performance.

VII. Product Selection
Selecting the right clutch is critical for the effective functionality of your machinery.
- Consequences of Improper Selection: An undersized clutch might fail to achieve rated capacity, while an oversized one increases costs and risks overheating, hastening wear and seal degradation.
- Selection Suggestions: Refer to our comprehensive product samples or consult with our expert technicians. We are committed to offering tailored selection advice to meet your specific needs.

VIII. Safety Precautions
(I) Protection during High - speed Rotation
Under no circumstances should the clutch be contacted by hands or objects while in high-speed rotation to prevent serious injury or damage.

(II) Protection from High Temperature
Avoid direct contact with the clutch immediately post-operation to prevent burns. Allow a half-hour cooldown after use before proceeding with any maintenance tasks.

(III) Side Protection
Standing beside a spinning clutch poses accident risks from debris. Utilize a protective cover for safety during use.

(IV) Attention during Ventilation Operation
To safeguard against injury, avoid touching friction pads with fingers during ventilation or air-stop operations.

(V) Safety of Internal Structure
Our clutches contain internal springs; unauthorized disassembly poses significant risks. Only qualified personnel should perform disassembly to ensure safety.
