(III) Easy Maintenance
- Simple Friction Pad Replacement: Replacing friction pads is straightforward and does not necessitate clutch disassembly, drastically cutting maintenance costs and time, boosting efficiency, and minimizing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: The distinctive disc arc design greatly enhances the product's heat dissipation capacity, effectively managing operational temperature, prolonging service life, and ensuring stability during prolonged high-load operations.
(V) Quick Response
- Fast Clutching and Braking: The product features swift response times, enabling rapid clutching and braking functionalities to meet the demands of various mechanical systems, thereby augmenting production efficiency.
(VI) Diverse Connection Methods
- Flexible Connection Options: Outfitted with versatile connection methods, it offers adaptable solutions to meet varying site requirements, ensuring a perfect complement to diverse equipment.


III. Product Structure
The pneumatic clutch brake is comprised of critical components including:
- Clutch Body: Mounted on the main shaft of the equipment, the center hole size is customizable based on customer specifications (refer to the sample for size range), serving as the integral component of the clutch.
- Clutch Ear Plate and Brake Ear Plate: Meticulously connected to the flywheel and machine body through four precision-engineered pins, these components ensure the unwavering stability and seamless operation of the clutch and brake mechanisms.
- Friction Pads (Blocks): These essential elements play a pivotal role in the intricate clutching and braking process, facilitating the smooth transmission and interruption of power with remarkable efficiency.
- Clutch Pins, Brake Pins and Locking Plates: These components are vital for the secure connection and fixation of various parts. The locking plates, expertly embedded in the pin grooves, are securely fastened to the flywheel or machine body with screws, preventing any axial movement and ensuring operational stability.


IV. Working Principle
(I) Clutching Process
External compressed air is expertly channeled into the clutch cylinder through the strategically placed intake hole, propelling the piston into action. This dynamic movement, in conjunction with the friction pads, clutch body, and flat key, rotates the driven part, seamlessly engaging the clutch and facilitating the efficient transmission of power.

(II) Braking Process
Upon halting the air supply, the piston is intuitively driven in the opposite direction by the spring's force. Through the friction pads, clutch body, and flat key, the driven part is swiftly and precisely braked, with an astonishing braking time of just 0.01 - 0.02 seconds. This rapid response ensures the equipment can halt with exceptional agility.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
For optimal installation accuracy and stability, the hole tolerance for the four pins should adhere to H7 standards, with the hole center aligned in parallel to the main shaft center.

(II) Geometric Tolerance and Roughness Requirements
Maintain strict compliance with national standards for the geometric tolerance and roughness of the center hole and keyway. The main shaft's geometric tolerance and roughness should also adhere to the corresponding specifications to enhance superior product performance.

(III) Installation Sequence Suggestions
Customers are advised to customize their installation sequence based on specific conditions. Generally, it is recommended to commence with the clutch and brake ear plates, pins, and locking plates, followed by the installation of the clutch brake body for optimal results.

(IV) Installation Notes for Square Pins
Square pins are expertly designed to mitigate installation size discrepancies between two pins and to counteract the plate's thermal deformation due to clutch heating. Ensure that the two flat surfaces of the square pin align precisely parallel to the radial direction of the ear plate.

(V) Sealing Requirements for Axial Air Intake
In cases of axial air intake, it is crucial to install sealing caps at both ends of the clutch to effectively prevent any gas leakage, ensuring the system's integrity.

(VI) Check after Installation
Following installation, verify that the clutch end and brake end can move freely without hindrance. This ensures the continued, reliable operation of the clutch and brake systems.

Product Description

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each clutch from Shandong Tenord Machinery Equipment Co., Ltd. undergoes rigorous quality checks prior to shipment. Customers must refrain from unauthorized disassembly of the clutch units. Any damage resulting from such actions will not be covered by our warranty policies. Should you encounter any issues regarding the product quality, promptly contact us to ensure swift resolution.

(II) Friction Pad Replacement Method
Friction pads in the Precision Clutch Brake Punching Machine for Eccentric Press Efficiency are wear-and-tear components. When heavily worn due to prolonged use, they require replacement. Our design allows for a straightforward replacement process without removing ear plates or the clutch itself. Follow these efficient steps for replacement:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Proceed to remove the bolts and nuts securing the friction pads. Replace with new friction pads, then securely tighten the bolts and nuts to ensure optimal operation.
- Replacement with Air Supply: Loosen the brake ear plate and follow the aforementioned steps to ensure seamless replacement of the friction pads.

(III) Timing for Friction Pad Replacement
- For heavy machinery like presses, if the equipment fails to achieve its rated performance, inspect the friction pads for wear and consider replacement if necessary.
- In cases where the friction pads' wear exceeds 50% of their original state, timely replacement is advised to maintain peak operational efficiency.

VII. Product Selection
Selecting the right clutch for your specific needs is vital for the efficacy of your equipment. Considerations should be made with precision and expertise.
- Consequences of Improper Selection: A clutch that is undersized will fail to meet operational demands; conversely, an oversized clutch increases both cost and risks of overheating, hastening friction pad deterioration and sealing ring degradation.
- Selection Suggestions: Refer to our comprehensive product samples or consult with our skilled technicians. We are dedicated to offering expert advice to assist in your selection process.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
To prevent accidents, avoid any physical contact with the clutch while it is operating at high speed.

(II) Protection from High Temperature
After the clutch ceases operation, refrain from immediate contact to prevent burns. Allow approximately 30 minutes for cooling to room temperature before any maintenance activities.

(III) Side Protection
To guard against potential hazards from debris, do not stand beside a rotating clutch. Ensure a protective cover is in place during operation for enhanced safety.

(IV) Attention during Ventilation Operation
During air supply and ventilation tasks, keep fingers clear of friction pads to avoid injury.

(V) Safety of Internal Structure
The internal spring mechanism of the clutch demands caution. Unauthorized disassembly is prohibited to prevent injury. Only qualified professionals should undertake such tasks when necessary.
