(I) Application Fields
This paramount product is extensively applied across numerous industries, including forging, printing, textile, welding, and shipbuilding. It garners particular acclaim in metal processing, paper processing machinery, woodworking machinery, and fiber machinery sectors.

II. Product Advantages
(I) Compact Structure
- With a diminutive axial size and feather-light weight, the design minimizes inherent rotational inertia. This significantly streamlines the equipment's volume and weight, enhancing operational efficiency while sustaining peak performance.
(II) Safe and Reliable
- Innovative Asbestos-Free Friction Material: Outfitted with friction materials completely devoid of asbestos, it assures no health hazards, aligning with contemporary environmental and safety standards to offer users a safe, reliable experience.
(III) Easy Maintenance
- Effortless Friction Pad Replacement: Uncomplicated friction pad swaps without dismantling the clutch drastically lower maintenance costs and time, boosting efficiency and curtailing downtime.
(IV) Excellent Heat Dissipation Performance
- Ingenious Disc Arc Design: Its unique disc arc design exponentially enhances heat dissipation, effectively keeping operational temperatures in check. This prolongs product lifespan and ensures stability during extended high-load operations.
(V) Quick Response
- Swift Clutch and Brake Functionality: With lightning-fast response times, it executes clutching and braking with remarkable agility, fulfilling the demand for swift mechanical operations and pushing production efficiency to new heights.
(VI) Diverse Connection Methods
- Versatile Connection Options: Offering a plethora of connection methods, it adapts flexibly to varied site requirements, seamlessly integrating with a wide range of equipment.


III. Product Structure
Core Components of the Pneumatic Clutch Brake System:
- Clutch Body: The pivotal component fixed on the equipment's main shaft. Its center hole size is customizable to meet client specifications (refer to sample for size range), serving as the clutch's nucleus.
- Clutch Ear Plate and Brake Ear Plate: These crucial components are seamlessly integrated into the flywheel and machine body through a quartet of reliable pins, ensuring the clutch and brake operate with unwavering stability and precision.
- Friction Pads (Blocks): These indispensable elements drive the clutching and braking process by efficiently managing the power transfer and its interruption, making them a cornerstone of performance.
- Clutch Pins, Brake Pins, and Locking Plates: These integral parts connect and secure various components firmly in place. Locking plates are skillfully embedded within pin grooves and secured to the flywheel or machine body with screws, preventing any undesirable axial movement of the pins.


IV. Working Principle
(I) Clutching Process
Compressed air dynamically enters the clutch cylinder via the intake hole, propelling the piston forward. This action, through the adept friction pads, clutch body, and flat key, engages the driven part, facilitating the seamless transmission of power.

(II) Braking Process
When the air supply ceases, the piston swiftly retracts under the spring's influence. This prompt action, aided by the friction pads, clutch body, and flat key, ensures the driven part is rapidly braked, achieving a remarkable stopping time of merely 0.01 - 0.02 seconds, guaranteeing quick equipment cessation.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
To uphold the installation's precision and stability, ensure the four pin holes conform to an H7 tolerance, with their centers perfectly parallel to the main shaft center.

(II) Geometric Tolerance and Roughness Requirements
Meticulously adhere to national standards for the geometric tolerance and roughness of both the center hole and keyway. Likewise, the main shaft's geometric tolerance and roughness must align with these standards to elevate product performance.

(III) Installation Sequence Suggestions
In customizing the installation sequence, customers can adapt to their specific situation. Typically, begin with the clutch and brake ear plates, pins, and locking plates, followed by the installation of the clutch brake body for optimal efficiency.

(IV) Installation Notes for Square Pins
Square pins play a pivotal role in rectifying any installation size discrepancies and in counteracting the thermal deformation of plates due to clutch heating. Ensure the two flat surfaces of the square pin maintain parallel alignment with the radial direction of the ear plate.

(V) Sealing Requirements for Axial Air Intake
In the case of axial air intake, fitting sealing caps at both clutch ends is crucial to effectively prevent gas leakage and maintain system integrity.

(VI) Check after Installation
Post-installation, verify that the clutch end and brake end operate with complete freedom to confirm the clutch and brake's optimal functioning and reliability.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every clutch we offer has passed stringent acceptance tests, ensuring premium quality and reliability. Customers are advised against unauthorized disassembly, as doing so voids any responsibility on our part for resulting damages. Should any quality concerns arise, please contact us promptly for swift and effective resolution.

(II) Friction Pad Replacement Method
Friction pads are designed as consumable components, necessitating replacement after extensive use and significant wear. Our innovative clutch design allows for straightforward pad replacement without disassembling ear plates or the clutch itself. Here's how you can effortlessly replace them:
- Replacement without Air Supply: Simply loosen the clutch ear plate, proceed to remove the bolts and nuts securing the worn friction pads, replace with fresh ones, and ensure all fasteners are tightened securely.
- Replacement with Air Supply: Begin by loosening the brake ear plate and follow the aforementioned steps to easily replace with new friction pads.

(III) Timing for Friction Pad Replacement
- Especially in machinery like presses, if performance declines below the rated capacity, inspect friction pads for wear and replace if necessary.
- Once wear surpasses half the original thickness, timely replacement of friction pads is crucial to maintain optimal functionality.

VII. Product Selection
Choosing the right clutch is vital for equipment efficiency and longevity. Selecting an appropriately sized clutch enhances performance and ensures seamless operation.
- Consequences of Improper Selection: An undersized clutch will fail to meet capacity requirements, whereas an oversized one increases costs, risks overheating, and accelerates wear on friction pads and seals.
- Selection Suggestions: To ascertain the perfect fit, consult our comprehensive company samples or seek guidance from our expert technicians who are ready to offer tailored recommendations.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
Avoid contact with the clutch during its high-speed rotation to prevent hazardous situations. Safety first!

(II) Protection from High Temperature
Post-operation, refrain from touching the clutch immediately to prevent burns. Allow approximately 30 minutes for cooling before undertaking maintenance tasks.

(III) Side Protection
Standing beside the rotating clutch poses risks due to potential projectile hazards. Always ensure a protective cover is securely in place during operation.

(IV) Attention during Ventilation Operation
During air operations, hands must be kept away from friction pads to avoid painful pinching injuries.

(V) Safety of Internal Structure
Our clutches integrate internal springs; unauthorized disassembly is hazardous. Professional expertise is required for any internal maintenance work to safeguard against injury.
