II. Product Advantages
(I) Compact Structure
- Small Axial Size and Light Weight: This feature ensures a low intrinsic rotational inertia, markedly reducing the equipment's overall volume and weight while maintaining superior performance, thereby enhancing the equipment's operational efficiency.
(II) Safe and Reliable
- Asbestos-free Friction Material: Our product employs asbestos-free friction materials, eliminating health hazards associated with asbestos, and adhering to modern environmental and safety standards, providing users with a secure and trustworthy experience.
(III) Easy Maintenance
- Effortless Friction Pad Replacement: Our design allows for straightforward replacement of friction pads without dismantling the clutch, significantly reducing maintenance costs and time, boosting efficiency, and minimizing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: This innovative design greatly enhances the product's heat dissipation capability, effectively reducing operational temperatures, prolonging product lifespan, and ensuring equipment stability during extended high-load operations.
(V) Quick Response
- Rapid Clutching and Braking: With an impressive response speed, it efficiently achieves clutching and braking functions, meeting the quick response requirements of various mechanical equipment, thus increasing production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Featuring multiple connection methods, this product can flexibly adapt to different site requirements, showing exceptional adaptability to precisely align with various equipment types.


III. Product Structure
The pneumatic clutch brake consists of the following vital components:
- Clutch Body: Mounted on the equipment's main shaft, the center hole size is customizable according to client specifications (refer to the sample for size range), serving as the clutch's core component.
- Clutch Ear Plate and Brake Ear Plate: These components are precisely and expertly connected to the flywheel and machine body with four precision-engineered pins. This installation guarantees seamless operation, ensuring both the clutch and brake systems function with unmatched stability and reliability.
- Friction Pads (Blocks): As crucial elements in the clutching and braking mechanism, these components play a vital role in facilitating smooth power transmission and precise interruption, allowing for flawless operation.
- Clutch Pins, Brake Pins, and Locking Plates: These essential connectors and securing components feature locking plates that are meticulously embedded in the pin grooves. They are robustly anchored to the flywheel or machine body using screws, effectively preventing any undesirable axial pin movement.


IV. Working Principle
(I) Clutching Process
When external compressed air dynamically enters the clutch cylinder through the intake hole, the piston is driven into action. This movement, coupled with the friction pads, clutch body, and flat key, ensures the driven part rotates smoothly, achieving flawless engagement and impeccable power transmission.

(II) Braking Process
Upon halting the air supply, the piston is expertly propelled in reverse by the spring's force. Through the interaction of friction pads, clutch body, and flat key, the driven part is rapidly braked within just 0.01 - 0.02 seconds, ensuring the equipment stops with exceptional speed and efficiency.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
The installation holes for the four pins must conform to an H7 tolerance, with the hole centers precisely parallel to the main shaft center. This meticulous alignment ensures impeccable installation accuracy and unparalleled stability of the pins.

(II) Geometric Tolerance and Roughness Requirements
Geometric tolerance and surface roughness of the center hole and keyway must strictly adhere to national standards. The customer's main shaft should meet these rigorous criteria to enhance the overall performance and reliability of the product.

(III) Installation Sequence Suggestions
Customers can choose the installation sequence based on their specific scenarios. Typically, for optimal results, it is advised to install the clutch and brake ear plates, pins, and locking plates first, followed by the clutch brake body.

(IV) Installation Notes for Square Pins
Ingeniously designed to mitigate installation errors between two pins and counteract the thermal deformation caused by clutch heating, square pins ensure the two flat surfaces remain parallel to the radial direction of the ear plate.

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

(VI) Check after Installation
Post-installation, it's crucial to verify that both the clutch end and brake end move effortlessly, ensuring the flawless and reliable operation of the clutch and brake mechanisms.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Our esteemed clientele can rest assured knowing that each and every clutch distributed by Shandong Tenord Machinery Equipment Co., Ltd. undergoes rigorous quality assurance procedures before reaching your hands. It is important to note that unauthorized disassembly of the clutch is strictly prohibited. Should any damage arise from such actions, our company cannot assume responsibility. However, should you encounter any quality-related concerns, we encourage you to reach out to us promptly. Our dedicated team is committed to resolving any issues with unparalleled efficiency.

(II) Friction Pad Replacement Method
The friction pads, integral components of our Heavy-Duty Clutch Brake Punching Machine for Eccentric Presses, are designed for longevity yet will inevitably require replacement after extensive use when signs of wear become apparent. Our company has ingeniously engineered the replacement process to be straightforward, eliminating the need for disassembling the ear plates and clutch. Follow these simple, detailed steps to maintain optimal performance:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Proceed to remove the bolts and nuts securing the friction pads. Replace these with brand new friction pads, ensuring that you tighten the bolts and nuts securely afterwards.
- Replacement with Air Supply: Similar to the above method, start by loosening the brake ear plate and follow the aforementioned steps to insert new friction pads for seamless operation.

(III) Timing for Friction Pad Replacement
- In machinery like presses, a failure to achieve rated capacity could signal the need for friction pad replacement.
- When the friction pads have worn down to more than half of their original thickness, timely replacement is crucial for maintaining machine efficiency and safety.

VII. Product Selection
Choosing the perfect clutch for your equipment is paramount, as it directly influences the operational success and longevity of your machinery.
- Consequences of Improper Selection: Opting for a clutch that is too small may hinder achieving the necessary capacity, while choosing an excessively large one can inflate costs and lead to overheating, thereby accelerating friction pad wear and expediting the deterioration of sealing rings.
- Selection Suggestions: Explore our comprehensive range of samples or engage with our knowledgeable technicians for expert advice in selecting the ideal clutch that meets your precise needs. We are poised to assist you with professional recommendations.

VIII. Safety Precautions
(I) Protection during High - speed Rotation
For your safety, it is imperative to avoid any contact with the clutch while it is operating at high speeds, as this can pose significant risks.

(II) Protection from High Temperature
After the clutch ceases its operation, it remains exceptionally hot. Refrain from direct contact to prevent burns. Allow approximately 30 minutes for the clutch to cool to ambient temperature before performing any maintenance tasks.

(III) Side Protection
To prevent accidents from potential flying debris, one must never position themselves to the side of a rotating clutch. Always ensure a protective cover is securely in place during operation.

(IV) Attention during Ventilation Operation
During the processes of ventilation or air stoppage, it is crucial to keep fingers clear of the friction pads to avoid injury through pinching.

(V) Safety of Internal Structure
The clutch's internal structure features springs, making it vital that only professionals handle any necessary disassembly. Unauthorized tampering is prohibited to prevent personal injury.
