(VI) Diverse Connection Methods
- Flexible Connection Options: Our product offers a variety of connection methods, adaptable to diverse site requirements, ensuring compatibility and perfect matching with various equipment.


III. Product Structure
The pneumatic clutch brake is composed of key components including:
- Clutch Body: Fixed on the equipment's main shaft, the center hole size is customizable per customer requirements (refer to sample for size range), serving as the clutch's pivotal component.
- Clutch Ear Plate and Brake Ear Plate: These critical components are ingeniously connected to the flywheel and machine body of the equipment respectively through a robust assembly of four pins, ensuring the stable and efficient operation of both the clutch and brake systems.
- Friction Pads (Blocks): These crucial elements play a pivotal role in the clutching and braking process, facilitating the seamless transmission and interruption of power that is fundamental to the machine's operation.
- Clutch Pins, Brake Pins and Locking Plates: These components are indispensable in the connection and stabilization of various parts. The locking plates, in particular, are expertly embedded in the pin grooves and firmly secured on the flywheel or machine body with screws, preventing any unwanted axial movement of the pins.


IV. Working Principle
(I) Clutching Process
External compressed air is ingeniously directed through the intake hole into the clutch cylinder, propelling the piston into motion. This dynamic interaction, through the friction pads, clutch body, and flat key, rotates the driven part, realizing clutch engagement and the efficient transmission of power.

(II) Braking Process
Upon cessation of air supply, the piston swiftly moves in the opposite direction under the spring's influence, utilizing the friction pads, clutch body, and flat key. This rapid action swiftly brakes the driven part in just 0.01 - 0.02 seconds, ensuring the equipment's quick stoppage and precision operation.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
To secure the four pins, the hole tolerance is meticulously set at H7, and the hole center must be parallel to the main shaft center, ensuring unparalleled installation accuracy and stability for optimal performance.

(II) Geometric Tolerance and Roughness Requirements
The geometric tolerance and roughness of the center hole and keyway are stringently aligned with national standards. Likewise, the customer's main shaft must adhere to these standards to significantly enhance product performance and reliability.

(III) Installation Sequence Suggestions
Customers are encouraged to tailor the installation sequence to their specific scenarios. Generally, it is recommended 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 are strategically utilized to rectify any installation size errors of the two pins and to counteract the plate thermal deformation due to clutch heating. It is essential that the two flat surfaces of the square pin are parallel to the radial direction of the ear plate to ensure precision.

(V) Sealing Requirements for Axial Air Intake
In cases of axial air intake, it is crucial to install sealing caps at both ends of the clutch to effectively prevent any gas leakage, maintaining system integrity.

(VI) Check after Installation
Post-installation, it is imperative to ensure that the clutch end and brake end exhibit smooth movement to guarantee the seamless and uninterrupted operation of the clutch and brake.

Product Description

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each clutch sold by our company undergoes meticulous quality assurance checks. Customers are advised against any private disassembly of the clutch, as it may lead to damage for which we cannot be held liable. Should you encounter any quality concerns, please alert us promptly. We are committed to resolving issues swiftly and efficiently.

(II) Friction Pad Replacement Method
The friction pads of this machine are consumable components that require timely replacement when significantly worn due to extensive use. Our friction pad replacement process is user-friendly, eliminating the need to disassemble the ear plates or the clutch itself. Follow these straightforward steps:
- Replacement without Air Supply: Simply loosen the clutch ear plate, remove the bolts and nuts securing the friction pads, replace them with new ones, and ensure the bolts and nuts are firmly tightened.
- Replacement with Air Supply: Loosen the brake ear plate and follow the previous instructions to seamlessly replace the friction pads.

(III) Timing for Friction Pad Replacement
- If the machine, such as a press, fails to achieve its rated capacity, inspect the friction pads for potential replacement.
- Once the wear of the friction pads surpasses half of their original thickness, it is imperative for customers to perform a timely replacement.

VII. Product Selection
Choosing the correct clutch size for your equipment is of paramount importance to ensure optimal performance.
- Consequences of Improper Selection: An undersized clutch may fail to deliver the necessary capacity, while an oversized clutch may not only inflate costs but also induce overheating, accelerating friction pad wear and sealing ring deterioration.
- Selection Suggestions: Customers are invited to refer to our company samples or consult our expert technicians for tailored advice. We are dedicated to offering knowledgeable guidance to assist you in making the best selection.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
For utmost safety, never allow hands or objects to come into contact with the clutch while it is in high-speed rotation, as this could pose significant danger.

(II) Protection from High Temperature
Avoid direct contact with the clutch immediately after rotation ceases, as the high temperature can cause injury. Allow approximately 30 minutes for the clutch to cool to a safe, room temperature before conducting any maintenance.

(III) Side Protection
Standing beside a rotating clutch is strictly prohibited to prevent accidents from potential flying debris. Always ensure a protective cover is fitted over the clutch during operation.

(IV) Attention during Ventilation Operation
During the processes of ventilation and air stoppage, it is crucial to keep fingers clear of the friction pads to prevent being pinched.

(V) Safety of Internal Structure
The internal springs of the clutch necessitate professional handling. Avoid unsupervised disassembly to prevent injury. If disassembly is necessary, it should be undertaken by qualified personnel.
