(I) Application Fields
This versatile product finds extensive application in diverse industries including forging, printing, textiles, welding, and shipbuilding. Its performance has been particularly acclaimed in fields such as metal processing, paper processing machinery, woodworking machinery, and fiber machinery.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Light Weight: Features a minimal axial size and a lightweight build, complemented by low inherent rotational inertia. This effectively reduces the overall dimensions and weight of your machinery while maintaining performance, thereby enhancing operational efficiency.
(II) Safe and Reliable
- Asbestos-free Friction Material: Our friction material is free from asbestos, eliminating any potential health risks associated with asbestos exposure. This meets modern environmental and safety standards, offering users a distinctly safer and more reliable experience.
(III) Easy Maintenance
- Simplified Friction Pad Replacement: Replacing friction pads is remarkably simple and requires no clutch disassembly, significantly lowering maintenance costs and time. This enhances equipment maintenance efficiency and reduces downtime.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: The innovative disc arc design vastly elevates the product's heat dissipation capabilities, effectively reducing operational temperatures. This extends the product's service life and ensures stable performance even during prolonged, high-load operations.
(V) Quick Response
- Rapid Clutching and Braking: With an impressively fast response time, it swiftly executes clutching and braking functions, meeting the quick response demands of various mechanical equipment and boosting production efficiency.
(VI) Diverse Connection Methods
- Flexible Connection Options: Featuring multiple connection methods for selection based on distinct site requirements. This flexibility ensures robust adaptability and perfect compatibility with a variety of equipment.


III. Product Structure
The pneumatic clutch brake is primarily composed of the following integral components:
- Clutch Body: Mounted on the equipment's main shaft, the center hole size is customizable to meet customer specifications (refer to the sample for size range). This is the pivotal component of the clutch.
- Clutch Ear Plate and Brake Ear Plate: Securely connected to the flywheel and machine body of the equipment respectively through four robust pins, these components ensure the exceptional stability and smooth operation of both the clutch and brake.
- Friction Pads (Blocks): These essential elements play a pivotal role in the clutching and braking process, effectively managing the transmission and interruption of power to maintain seamless functionality.
- Clutch Pins, Brake Pins and Locking Plates: Expertly designed for the connection and securing of various components. The locking plates, ingeniously embedded in the pin grooves, are firmly attached to the flywheel or machine body with screws to prevent any unwanted axial movement of the pins.


IV. Working Principle
(I) Clutching Process
As external compressed air enters the clutch cylinder via the intake hole, it propels the piston into motion. This movement, transmitted through the friction pads, clutch body, and flat key, rotates the driven part, thus achieving clutch engagement and facilitating the seamless transmission of power.

(II) Braking Process
Upon ceasing the air supply, the piston swiftly moves in reverse due to the spring's action. This rapid movement, through the friction pads, clutch body, and flat key, quickly brakes the driven part. With an impressive braking time of just 0.01 - 0.02 seconds, the equipment can halt with remarkable speed and precision.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
The hole tolerance for the installation of the four pins should be H7. Additionally, to ensure unparalleled installation accuracy and stability, the hole center must be perfectly parallel to the main shaft center.

(II) Geometric Tolerance and Roughness Requirements
Geometric tolerance and roughness of the center hole and keyway must be in strict compliance with national standards. Similarly, the geometric tolerance and roughness of the customer's main shaft should adhere to the requisite standards to guarantee enhanced product performance.

(III) Installation Sequence Suggestions
Customers have the flexibility to choose the installation sequence based on specific scenarios. Typically, it is advisable to first install the clutch and brake ear plates, pins, and locking plates, followed by the installation of the clutch brake body.

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

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

(VI) Check after Installation
Post-installation, verify that the clutch end and brake end exhibit free movement to ensure the optimal and seamless functioning of the clutch and brake systems.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each clutch sold by Shandong Tenord Machinery Equipment Co., Ltd. has undergone rigorous quality control to ensure unparalleled reliability. We strongly advise against any unauthorized disassembly of the clutch, as it may lead to damage for which we cannot assume responsibility. However, should you encounter any quality concerns, please contact us promptly. Our dedicated team is committed to resolving any issues with the utmost efficiency.

(II) Friction Pad Replacement Method
Friction pads are vital yet consumable components of your Powerful Clutch Brake Punching Machine. Over time, they may experience wear and will require replacement. Fortunately, our innovative design allows for straightforward replacement without dismantling critical components such as the ear plates or clutch. Follow these streamlined steps for a hassle-free replacement:
- Replacement without Air Supply: Simply loosen the clutch ear plate, remove the securing bolts and nuts, replace the worn friction pads with new ones, and securely retighten the bolts and nuts to ensure proper operation.
- Replacement with Air Supply: Begin by loosening the brake ear plate, then follow the same procedure outlined above to replace the friction pads effectively.

(III) Timing for Friction Pad Replacement
- When using equipment such as presses, if the machine struggles to meet its rated capacity, it is essential to inspect the condition of the friction pads to determine if replacement is required.
- Replacement is necessary when the wear of friction pads surpasses half of their original thickness. Timely replacement will maintain optimal machine performance.

VII. Product Selection
Selecting the right clutch is crucial for maximizing the performance and longevity of your equipment. It is vital to choose wisely.
- Consequences of Improper Selection: An undersized clutch will fail to achieve the rated capacity, while an oversized clutch can drive up costs, lead to overheating, accelerate friction pad wear, and cause premature aging of sealing rings.
- Selection Suggestions: Choose from our comprehensive range or consult our expert technicians for tailored recommendations. Our team is ready to assist you with precision and expertise to ensure you make the perfect choice.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
To ensure your safety, strictly avoid any contact with the clutch or nearby objects during high-speed rotation to prevent accidents.

(II) Protection from High Temperature
Avoid direct contact with the clutch immediately after rotation ceases, as high temperatures pose a risk of scalding. Allow approximately 30 minutes for cooling before proceeding with maintenance tasks.

(III) Side Protection
Standing beside a rotating clutch is hazardous due to potential flying debris. Always use a protective cover to safeguard against such occurrences.

(IV) Attention during Ventilation Operation
Exercise caution during ventilation and air-stopping processes. Keep hands clear of friction pads to prevent injury.

(V) Safety of Internal Structure
The clutch contains internal springs; unauthorized disassembly is dangerous and should only be performed by qualified professionals to prevent injury.
