(III) Easy Maintenance
- Simplified Friction Pad Replacement: The friction pads can be effortlessly replaced without the need to disassemble the clutch, substantially lowering maintenance expenses and time. This enhances maintenance efficiency and minimizes equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Ingenious Disc Arc Design: This distinctive disc arc design significantly boosts the product's heat dissipation capabilities, effectively reducing operational temperatures. This prolongs the product's lifespan and ensures consistent equipment stability during prolonged, high-load operations.
(V) Quick Response
- Rapid Clutching and Braking: With its rapid response rate, it swiftly executes clutching and braking functions, catering to the quick-response demands of various mechanical equipment and enhancing production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Solutions: It offers multiple connection options that can be selected flexibly to meet diverse site requirements, showcasing remarkable adaptability and compatibility with a wide range of equipment.


III. Product Structure
The pneumatic clutch brake is composed of several key components:
- Clutch Body: Mounted on the equipment's main shaft, it features a customizable center hole size (refer to the sample size range), serving as the clutch's pivotal component.
- Clutch Ear Plate and Brake Ear Plate: Ingeniously connected to the flywheel and machine body through four precision-engineered pins, guaranteeing impeccable stability and smooth operation of both the clutch and the brake mechanisms.
- Friction Pads (Blocks): These pivotal components are the heart of the clutching and braking process, expertly managing the seamless transmission and interruption of power, thereby ensuring optimal performance.
- Clutch Pins, Brake Pins, and Locking Plates: These essential connectors and fixers assure the cohesion of various components. The meticulously designed locking plates are embedded within pin grooves and secured on the flywheel or machine body using screws, effectively preventing any unwanted axial pin movement.


IV. Working Principle
(I) Clutching Process
When external compressed air is introduced into the clutch cylinder via the intake hole, it propels the piston into motion. This action, aided by friction pads, the clutch body, and a flat key, rotates the driven part, thereby achieving flawless clutch engagement and seamless power transmission.

(II) Braking Process
Upon halting the air supply, the piston swiftly retracts under the spring's force. This reverse motion, facilitated by the friction pads, clutch body, and flat key, brings the driven part to an almost instantaneous halt, boasting a braking time of merely 0.01 - 0.02 seconds, enabling rapid and reliable stoppage of the equipment.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
To achieve precise installation accuracy and stability, the hole tolerance for the four pins must be H7, and the hole center should align parallelly with the main shaft center.

(II) Geometric Tolerance and Roughness Requirements
The geometric tolerance and roughness of both the center hole and keyway are bound by stringent national standards. Equally, the geometric tolerance and roughness of the customer's main shaft should adhere to these standards to enhance the product's performance.

(III) Installation Sequence Suggestions
Customers have the flexibility to choose an installation sequence tailored to their specific needs. Generally, it is advisable to first install the clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body for optimal results.

(IV) Installation Notes for Square Pins
Square pins serve the crucial purpose of eliminating installation size discrepancies between two pins and counteracting thermal deformation of plates due to clutch heating. Ensure the two flat surfaces of the square pin remain parallel to the radial direction of the ear plate for precise alignment.

(V) Sealing Requirements for Axial Air Intake
In the case of axial air intake, it is imperative to fit sealing caps at both ends of the clutch to effectively prevent any potential gas leakage.

(VI) Check after Installation
Post-installation, it is crucial to verify that the clutch end and brake end operate freely, ensuring the flawless functionality of the clutch and brake systems.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each clutch we offer has passed rigorous quality checks. Customers should refrain from disassembling the clutch themselves, as this voids any responsibility from our company for damage incurred. Should you encounter any quality issues, kindly reach out promptly, and we will address them swiftly.

(II) Friction Pad Replacement Method
The friction pads on our product are essential yet consumable, requiring replacement after prolonged use when wear becomes significant. Our design allows for hassle-free friction pad replacement without the need to disassemble the ear plates or clutch. Follow these effortless steps:
- Replacement without Air Supply: Simply loosen the clutch ear plate, remove the securing bolts and nuts, replace the worn pads with new ones, and then re-secure the bolts and nuts.
- Replacement with Air Supply: Similarly, loosen the brake ear plate and follow the aforementioned steps to upgrade to new friction pads.

(III) Timing for Friction Pad Replacement
- For heavy-duty machines like presses, if performance drops below expected capacity, inspect the friction pads for potential replacement.
- When friction pad wear exceeds fifty percent of their original thickness, prompt replacement is advised to maintain optimal performance.

VII. Product Selection
Choosing the right clutch is vital for the functionality and efficiency of your equipment.
- Consequences of Improper Selection: A clutch too small will not achieve full capacity, while an oversized clutch incurs unnecessary cost, risks overheating, accelerates friction pad wear, and hastens seal ring aging.
- Selection Suggestions: Refer to our company's samples for guidance or consult our expert technicians for tailored advice. We are dedicated to aiding your precise selection process.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
Never touch the clutch or any rotating components with hands or objects during operation, as it poses significant risk.

(II) Protection from High Temperature
It's imperative to avoid direct contact with the clutch immediately post-operation to prevent burns. Allow approximately thirty minutes for the clutch to cool to room temperature before undertaking any maintenance.

(III) Side Protection
Refrain from standing beside the rotating clutch to safeguard against potential projectiles. A protective cover should be utilized to minimize exposure to hazards.

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

(V) Safety of Internal Structure
The clutch harbors internal springs; unauthorized disassembly is prohibited to prevent injury. Any required disassembly should only be performed by skilled professionals.
