(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: This innovative design greatly enhances the product's heat dissipation capacity, effectively lowering operational temperatures, extending product lifespan, and ensuring equipment stability during prolonged high-load operations.
(V) Quick Response
- Rapid Clutching and Braking: With a swift response speed, it efficiently accomplishes clutching and braking functions, fulfilling the quick response demands of various mechanical equipment, thus boosting production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Featuring multiple connection methods, this product can adapt flexibly to different site requirements, exhibiting exceptional adaptability to precisely align with various equipment types.


III. Product Structure
The pneumatic clutch brake is composed of the following key 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: Seamlessly integrated with precision, these components connect to the flywheel and machine body through four expertly engineered pins. This ensures the unwavering and stable operation of both the clutch and brake systems, setting new benchmarks in efficiency and reliability.
- Friction Pads (Blocks): As vital components in the clutching and braking process, these friction pads orchestrate the smooth transmission, precise power interruption, and impeccable handling, guaranteeing peak performance.
- Clutch Pins, Brake Pins and Locking Plates: These elements are fundamental in connecting and securing crucial components. Locking plates are meticulously embedded within pin grooves, securely anchored to the flywheel or machine body with screws, effectively eliminating any undesirable axial pin movement.


IV. Working Principle
(I) Clutching Process
External compressed air swiftly enters the clutch cylinder through the intake hole, propelling the piston into action. This dynamic interplay with friction pads, clutch body, and flat key ensures the driven part rotates with precision, achieving flawless clutch engagement and seamless power transmission.

(II) Braking Process
Upon cessation of air supply, the piston is ingeniously propelled backward by spring force. The friction pads, clutch body, and flat key collaborate to brake the driven part within 0.01 - 0.02 seconds, guaranteeing a rapid and efficient stop with unmatched precision.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Installation holes for the four pins must achieve an H7 tolerance, with centers precisely parallel to the main shaft center, ensuring installation accuracy and stability that sets new standards.

(II) Geometric Tolerance and Roughness Requirements
Both geometric tolerance and surface roughness of the center hole and keyway must adhere strictly to national standards. The customer's main shaft must also meet these high standards to elevate overall product performance and reliability.

(III) Installation Sequence Suggestions
Customers enjoy the flexibility of choosing their installation sequence based on specific scenarios. Typically, installing the clutch and brake ear plates, pins, and locking plates first, followed by the clutch brake body, is recommended for optimal results.

(IV) Installation Notes for Square Pins
Ingeniously crafted, square pins are designed to correct installation size errors between two pins and counteract plate thermal deformation due to clutch heating. It's imperative to ensure the two flat surfaces of the square pin are parallel to the radial direction of the ear plate.

(V) Sealing Requirements for Axial Air Intake
For systems employing axial air intake, installing sealing caps at both ends of the clutch is essential to prevent gas leakage and maintain the system's integrity.

(VI) Check after Installation
After installation, it is crucial that both the clutch end and brake end move effortlessly, ensuring the flawless and reliable operation of the clutch and brake mechanisms, securing impeccable performance.

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. We emphasize that unauthorized disassembly of the clutch is strictly prohibited. Should any damage arise from such actions, our company cannot assume responsibility. However, if you encounter any quality-related concerns, we urge you to contact us promptly. Our dedicated team is committed to resolving any issues with unparalleled efficiency and care.

(II) Friction Pad Replacement Method
The friction pads, integral components of our Heavy-Duty Clutch Brake Punching Machine for Eccentric Presses, are engineered for longevity, yet after extensive use, they will inevitably require replacement as signs of wear become apparent. Our company has ingeniously simplified the replacement process, eliminating the need for disassembling the ear plates and clutch. Follow these easy, detailed steps for maintaining 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 for optimal performance.
- 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 and efficient 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 as it might impact the machine's performance.
- 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, ensuring smooth operation.

VII. Product Selection
Choosing the perfect clutch for your equipment is paramount, as it directly influences the operational success and longevity of your machinery, ensuring efficiency and reliability.
- 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, ultimately affecting performance.
- 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 to ensure the best operational results.

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 and potential injury.

(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 for safe handling.

(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 to safeguard personnel.

(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, ensuring personal safety.

(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 and maintain integrity.
