(I) Application Fields
This versatile product finds extensive applications in several industries, including forging, printing, textile, welding, and shipbuilding. It has garnered acclaim for its superior performance in specialized fields such as metal processing, paper machinery, woodworking, and fiber machinery.

II. Product Advantages
(I) Compact Structure
- Reduced Axial Size and Lightweight Design: Featuring a minimal axial size and a lightweight design, it possesses low inherent rotational inertia. This not only minimizes the overall size and weight of the machinery but also enhances operational efficiency, maintaining robust performance.
(II) Safe and Reliable
- Asbestos-Free Friction Material: Our clutch brake employs friction materials devoid of asbestos, eliminating associated health risks and aligning with contemporary environmental and safety standards for a safer user experience.
(III) Easy Maintenance
- Simplified Friction Pad Replacement: Designed for straightforward friction pad replacement without the need for disassembly, this feature significantly lowers maintenance costs and time, boosting maintenance efficiency and minimizing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Innovative Disc Arc Design: The product's unique disc arc design markedly enhances its heat dissipation capacity, effectively reducing operational temperatures, prolonging product lifespan, and ensuring stable equipment performance during extended high-load operations.
(V) Quick Response
- Rapid Clutch and Brake Activation: Engineered for swift response times, it executes clutching and braking functions with speed, catering to the quick response demands of various mechanical systems and elevating production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Featuring multiple connection methods for adaptable use based on site-specific requirements, it excels in compatibility and can seamlessly integrate with diverse equipment setups.


III. Product Structure
The pneumatic clutch brake is composed of critical components including:
- Clutch Body: Designed for installation on the equipment's main shaft, featuring a customizable center hole size that adheres to client specifications (refer to sample for size range), serving as the pivotal element of the clutch system.
- Clutch Ear Plate and Brake Ear Plate: Meticulously connected to the flywheel and body of the machine via four robust pins, these components are the unsung heroes ensuring the impeccable stability and seamless operation of both the clutch and brake mechanisms.
- Friction Pads (Blocks): As the essential heart of the clutching and braking process, these pads masterfully facilitate the transmission and interruption of power, defining the efficiency and reliability of your operations.
- Clutch Pins, Brake Pins and Locking Plates: These components are crucial for the secure connection and fixing of various elements. Locking plates, nestled in pin grooves and securely fastened to the flywheel or machine body with screws, prevent any unwanted axial movement of the pins.


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

(II) Braking Process
Ceasing air supply prompts the piston to retract under spring tension. This reverse action, via the friction pads, clutch body, and flat key, halts the driven part with remarkable swiftness in only 0.01 - 0.02 seconds, guaranteeing rapid equipment cessation.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
To achieve optimal installation precision and pin stability, the hole tolerance for the four pins must be H7, with the hole center perfectly parallel to the main shaft center.

(II) Geometric Tolerance and Roughness Requirements
The geometric tolerance and surface roughness of the center hole and keyway are mandated to comply with national standards. Similarly, the main shaft's geometric tolerance and roughness should meet corresponding standards to enhance the product's performance.

(III) Installation Sequence Suggestions
Installers can adapt the sequence based on their specific scenarios. Typically, it's advisable to first install the clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body, ensuring a smooth assembly process.

(IV) Installation Notes for Square Pins
Square pins are vital in correcting installation size discrepancies between two pins and compensating for plate thermal deformation due to clutch heating. Ensure that the two flat surfaces of the square pin are parallel to the radial direction of the ear plate for optimal functionality.

(V) Sealing Requirements for Axial Air Intake
For axial air intake systems, sealing caps must be installed at both ends of the clutch to effectively prevent any gas leakage and maintain system integrity.

(VI) Check after Installation
Post-installation, ensure that both the clutch end and brake end exhibit free movement, confirming the proper and efficient operation of the clutch and brake.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
At Shandong Tenord Machinery Equipment Co., Ltd., every clutch we provide has been rigorously tested to ensure optimal performance. Customers are advised against unauthorized disassembly, as this could void any responsibility for damages. In the event of any quality concerns, please contact us promptly, and we will address the issue with utmost urgency.

(II) Friction Pad Replacement Method
The friction pads in our Durable Clutch Brake Punching Machine are essential consumables and must be replaced when heavily worn due to extended use. Our design allows for straightforward replacement without removing the ear plates and clutch. Here is the streamlined process:
- Replacement without Air Supply: Simply loosen the clutch ear plate, remove the securing bolts and nuts, switch out the old friction pads with new ones, and resecure the bolts and nuts for seamless operation.
- Replacement with Air Supply: Follow the same simple procedure by loosening the brake ear plate and swapping the friction pads for fresh ones, ensuring your machine's longevity.

(III) Timing for Friction Pad Replacement
- For machines like presses, inspect friction pads when the equipment no longer meets its rated capacity. Timely replacement ensures optimal functionality.
- Once friction pads wear down to half their original thickness, it's crucial to replace them promptly to maintain efficiency and safety.

VII. Product Selection
For effective performance, selecting the right clutch for your equipment is vital. The perfect fit enhances both operation and longevity.
- Consequences of Improper Selection: An undersized clutch fails to deliver the required power; an oversized one unnecessarily inflates costs and risks overheating, leading to accelerated wear and sealing ring degradation.
- Selection Suggestions: Utilize our comprehensive samples or consult our technical experts. We are committed to offering tailored, expert advice to ensure the optimal choice for your needs.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
For your safety, never attempt to touch the clutch while it is in high-speed rotation. This precaution prevents potential injury from fast-moving components.

(II) Protection from High Temperature
Avoid direct contact with the clutch immediately after use, as high temperatures can cause burns. Allow the clutch to cool for approximately 30 minutes before any maintenance activities.

(III) Side Protection
Standing on the side of a rotating clutch is hazardous due to the risk of debris ejection. Always employ a protective cover to safeguard against potential accidents.

(IV) Attention during Ventilation Operation
During ventilation or air-stopping operations, refrain from touching the friction pads with your fingers to prevent pinching injuries.

(V) Safety of Internal Structure
Our clutches contain internal springs. To prevent injury, avoid unauthorized disassembly. Any necessary disassembly should be performed by qualified professionals only.
