(I) Application Fields
This product is extensively employed in a variety of industries, including forging, printing, textiles, welding, and shipbuilding. It receives exceptional acclaim particularly in sectors like metal processing, paper processing machinery, woodworking machinery, and fiber machinery.

II. Product Advantages
(I) Compact Structure
- Minimal Axial Size and Lightweight: With a reduced axial size and light weight coupled with low intrinsic rotational inertia, it significantly minimizes the overall dimensions and weight of the equipment while maintaining optimal performance, thus elevating the equipment's operational efficiency.
(II) Safe and Reliable
- Asbestos-free Friction Material: Featuring friction materials devoid of asbestos, it eliminates potential health risks associated with asbestos, aligning with contemporary safety and environmental standards to offer a safer, more reliable user experience.
(III) Easy Maintenance
- Effortless Friction Pad Replacement: The process of replacing friction pads is extremely straightforward and does not necessitate the disassembly of the clutch, drastically cutting down on maintenance costs and time. This enhances maintenance efficiency and reduces downtime.
(IV) Excellent Heat Dissipation Performance
- Innovative Disc Arc Design: The exclusive disc arc design greatly enhances the product's heat dissipation capabilities, effectively lowering operational temperatures, prolonging the product's service life, and ensuring equipment stability during prolonged high-load operations.
(V) Quick Response
- Rapid Clutching and Braking: With exceptional response speed, it swiftly executes clutching and braking functions, catering to the rapid response demands of various mechanical equipment and boosting production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Equipped with a variety of connection methods, it can be flexibly adapted to diverse site requirements, offering robust adaptability and seamless compatibility with various equipment.


III. Product Structure
The pneumatic clutch brake is composed of the following key components:
- Clutch Body: Mounted on the equipment's main shaft, its center hole size is customizable based on customer specifications (refer to sample size range). It serves as the clutch's core component.
- Clutch Ear Plate and Brake Ear Plate: Ingeniously attached to the flywheel and machine body using four precision-engineered pins, these components guarantee the impeccable stability and smooth operation of both the clutch and brake.
- Friction Pads (Blocks): These vital components are the heart of the clutching and braking process, expertly facilitating the seamless transmission and interruption of power with absolute precision.
- Clutch Pins, Brake Pins, and Locking Plates: These robust elements are crucial for securely connecting and fixing various components. The meticulously designed locking plates are cleverly embedded in the pin grooves and firmly anchored with screws on the flywheel or machine body to effectively prevent any axial movement of the pins.


IV. Working Principle
(I) Clutching Process
External compressed air is expertly channeled into the clutch cylinder through the intake hole, propelling the piston to move. This action ingeniously engages the clutch, allowing the driven part to rotate and power to be transmitted, thanks to the synergy of friction pads, clutch body, and flat key.

(II) Braking Process
When air supply is halted, the spring-driven piston shifts in reverse, swiftly braking the driven part within an astonishing 0.01 - 0.02 seconds. This ensures rapid cessation of equipment operation, safeguarded by the friction pads, clutch body, and flat key.

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

(II) Geometric Tolerance and Roughness Requirements
To optimize product performance, the geometric tolerance and roughness of both the center hole and keyway must strictly adhere to national standards, as should the customer's main shaft specifications.

(III) Installation Sequence Suggestions
While customers can tailor the installation sequence to their specific requirements, a recommended approach is to initially install the clutch and brake ear plates, pins, and locking plates, followed by the assembly of the clutch brake body.

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

(V) Sealing Requirements for Axial Air Intake
For axial air intake systems, it is imperative to install sealing caps at both ends of the clutch to effectively prevent any gas leakage and ensure system integrity.

(VI) Check after Installation
After completing installation, it is crucial to confirm that both the clutch end and brake end move effortlessly to guarantee the flawless operation of the clutch and brake system.

Product Description

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each clutch we offer has been rigorously tested to meet our high standards. Customers are advised not to disassemble the clutch on their own. Any damage resulting from unauthorized disassembly will not be covered by our warranty. If you encounter any quality issues, please contact us immediately, and we will address them promptly.

(II) Friction Pad Replacement Method
The friction pads are designed as wear-and-tear components and should be replaced after extensive use when they show significant wear. Our friction pad replacement process is straightforward and does not require dismantling the ear plates or the clutch. Here's how you can replace them:
- Replacement without Air Supply: Simply loosen the clutch ear plate, unscrew the bolts and nuts securing the friction pads, swap in new friction pads, and re-tighten the bolts and nuts.
- Replacement with Air Supply: Loosen the brake ear plate and follow the same procedure to install new friction pads.

(III) Timing for Friction Pad Replacement
- For machinery like presses, if the machine no longer achieves its rated capacity, inspect the friction pads for potential replacement.
- Once the wear on the friction pads surpasses fifty percent, it is important to replace them promptly to ensure optimal performance.

VII. Product Selection
Choosing the correct clutch is vital for the optimal functionality of your equipment.
- Consequences of Improper Selection: A clutch that's too small won't deliver the required capacity, while an oversized clutch can lead to increased costs, overheating, accelerated friction pad wear, and faster sealing ring degradation.
- Selection Suggestions: Customers are encouraged to refer to our detailed product samples or consult with our expert technicians. We are here to offer you tailored recommendations for the perfect clutch fit.

VIII. Safety Precautions
(I) Protection during High-Speed Rotation
Avoid any contact with the clutch, whether by hand or objects, during high-speed rotation to prevent accidents.

(II) Protection from High Temperature
Do not touch the clutch immediately after it stops to prevent burns. Allow approximately thirty minutes for the clutch to cool to ambient temperature before performing any maintenance.

(III) Side Protection
Standing next to a rotating clutch is hazardous due to the risk of flying debris. Always use a protective cover while the clutch is in operation.

(IV) Attention during Ventilation Operation
During the ventilation process, ensure that fingers are kept away from the friction pads to prevent injury.

(V) Safety of Internal Structure
The clutch houses internal springs. Unauthorized disassembly is dangerous and should be avoided. If necessary, such procedures must be performed by qualified professionals.
