(III) Easy Maintenance
- Simplified Friction Pad Replacement: The friction pads can be effortlessly replaced without necessitating clutch disassembly, significantly reducing maintenance costs and time, boosting maintenance efficiency, and decreasing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Innovative Disc Arc Design: Our unique disc arc configuration dramatically enhances heat dissipation capabilities, effectively lowering operational temperatures, extending service life, and guaranteeing equipment stability even during prolonged high-load usage.
(V) Quick Response
- Swift Clutching and Braking: With rapid response speeds, this unit efficiently executes clutching and braking functions, catering to mechanical equipment demands for quick response and boosting production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Equipped with multiple connection methods, this unit offers flexible adaptability to diverse site requirements, ensuring seamless compatibility with various equipment.


III. Product Structure
The pneumatic clutch brake is expertly composed of the following integral components:
- Clutch Body: This pivotal component, mounted on the equipment's main shaft, features a customizable center hole size tailored to specific customer requirements (refer to the sample for size range). It serves as the clutch's core element.
- Clutch Ear Plate and Brake Ear Plate: Designed with precision, these components are seamlessly connected to the equipment's flywheel and body through four robust pins, ensuring unparalleled stability and efficiency in the clutch and brake operations.
- Friction Pads (Blocks): These essential components expertly facilitate the clutching and braking processes, allowing for seamless power transmission and interruption, making them indispensable to the machine's functionality.
- Clutch Pins, Brake Pins, and Locking Plates: Essential for the secure connection and stability of various parts, the locking plates are meticulously embedded into the pin grooves, and securely fastened to the flywheel or machine body with precision screws to prevent any unintended axial movement.


IV. Working Principle
(I) Clutching Process
As external compressed air flows into the clutch cylinder through the intake hole, it propels the piston into action. This movement, transmitted through the friction pads, clutch body, and flat key, initiates the rotation of the driven part, achieving smooth clutch engagement and effective power transmission.

(II) Braking Process
Upon halting the air supply, the piston swiftly reverses under spring force, and through the friction pads, clutch body, and flat key, the driven part is rapidly brought to a stop. With an impressive braking time of merely 0.01 - 0.02 seconds, this ensures the equipment halts with precision and speed.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Ensure that the hole tolerance for the four pins is at H7 with the hole center precisely parallel to the main shaft center. This is crucial for maintaining the accuracy and stability of the pins during installation.

(II) Geometric Tolerance and Roughness Requirements
The geometric tolerance and surface roughness of the center hole and keyway must strictly adhere to national standards. Likewise, the main shaft's characteristics should align perfectly with these standards, optimizing the product's performance.

(III) Installation Sequence Suggestions
While the installation sequence can be adapted to specific needs, it is generally advisable to initially install the clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body for optimal assembly.

(IV) Installation Notes for Square Pins
Square pins are integral in correcting installation size discrepancies and counteracting plate thermal deformation from clutch heating. It is essential that the flat faces of the square pin maintain parallel alignment with the radial direction of the ear plate.

(V) Sealing Requirements for Axial Air Intake
For systems utilizing axial air intake, it is critical to install sealing caps at both ends of the clutch to effectively prevent any gas leakage and maintain operational integrity.

(VI) Check after Installation
Post-installation, it is imperative to confirm that the clutch and brake ends can move smoothly and without obstruction, ensuring that both the clutch and brake are in optimal working condition.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each clutch from Shandong Tenord Machinery Equipment Co., Ltd. is crafted with precision and undergoes rigorous quality checks. Customers must refrain from unauthorized disassembly of the clutch. Any damage resulting from such actions will not be covered by our company. Should you encounter any quality issues, please notify us promptly, and our team will expedite a solution to ensure your satisfaction.

(II) Friction Pad Replacement Method
Our friction pads are designed to be easily replaceable. Over time, these consumable parts may wear out and need replacement. Fortunately, replacing the friction pads in our machines is straightforward and requires no disassembly of ear plates or the clutch itself. Follow these steps to ensure seamless replacement:
- Replacement without Air Supply: Gently loosen the clutch ear plate, remove the bolts and nuts securing the worn-out friction pads, replace them with new ones, and securely fasten the bolts and nuts.
- Replacement with Air Supply: Similarly, loosen the brake ear plate and follow the same procedure to replace the friction pads efficiently.

(III) Timing for Friction Pad Replacement
- For machines like presses, check the friction pads if the equipment fails to achieve its rated capacity, indicating a need for replacement.
- When the wear level of the friction pads surpasses half their original thickness, prompt replacement is advisable to maintain optimal performance.

VII. Product Selection
Choosing the right clutch is vital for the effective operation of your equipment. It is essential to select the appropriate size to ensure efficiency and longevity.
- Consequences of Improper Selection: A clutch that is too small will underperform, while an oversized clutch will not only escalate equipment costs but also cause overheating, excessive wear of friction pads, and premature aging of sealing rings.
- Selection Suggestions: Refer to our comprehensive samples or consult our expert technicians for tailored advice. We are committed to guiding you towards an ideal selection that meets your requirements.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
Under no circumstances should the clutch be touched with hands or any objects during high-speed rotation, as this poses a significant risk of injury.

(II) Protection from High Temperature
Avoid direct contact with the clutch immediately after operation to prevent burns. Allow approximately 30 minutes for the clutch to cool to a safe temperature before undertaking any maintenance tasks.

(III) Side Protection
Standing beside the rotating clutch is strictly prohibited to prevent accidents from flying debris. Always use a protective cover when the clutch is in operation.

(IV) Attention during Ventilation Operation
During the ventilation and air-stopping phases, avoid touching the friction pads with fingers to prevent pinching hazards.

(V) Safety of Internal Structure
The clutch contains internal springs. Unauthorized disassembly is dangerous and could lead to injury. Any disassembly should be performed exclusively by trained professionals.
