(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: Enjoy superior heat dissipation with our unique disc arc design, which effectively manages operational temperatures, prolongs service life, and ensures stability during prolonged high-load operations.
(V) Quick Response
- Fast Clutching and Braking: Benefit from rapid response times that facilitate swift clutching and braking actions, meeting the demanding needs of various mechanical equipment and significantly enhancing production efficiency.
(VI) Diverse Connection Methods
- Flexible Connection Options: The product offers a range of connection methods to suit different site requirements, ensuring robust adaptability and seamless compatibility with various equipment.


III. Product Structure
The pneumatic clutch brake primarily comprises the following components:
- Clutch Body: Installed on the main shaft of the equipment, this core component can be customized to fit specific customer requirements, with center hole sizes available as per sample specifications.
- Clutch Ear Plate and Brake Ear Plate: These pivotal components are seamlessly connected to the flywheel and machine body through a robust arrangement of four pins. This ensures a remarkably stable operation for both the clutch and brake, delivering unparalleled performance.
- Friction Pads (Blocks): Essential in the dynamic clutching and braking process, these friction pads are instrumental in the seamless transmission and interruption of power, ensuring smooth and efficient operations.
- Clutch Pins, Brake Pins and Locking Plates: Designed for precision connectivity and stability, these components are critical. Locking plates, ingeniously embedded within the pin grooves, are securely fastened to the flywheel or machine body with screws, expertly deterring any unwanted axial movement of the pins.


IV. Working Principle
(I) Clutching Process
In the clutching process, an influx of compressed air through the intake hole propels the piston into action. This intricate movement, aided by friction pads, clutch body, and flat key, facilitates the seamless rotation of the driven part, ensuring effective clutch engagement and power transmission.

(II) Braking Process
Upon halting the air supply, the piston adeptly reverses direction with the assistance of a spring. This swift movement, combined with friction pads, clutch body, and flat key, effectuates a rapid braking of the driven part. The braking is executed in an astonishingly brief 0.01 - 0.02 seconds, guaranteeing an immediate stop for the equipment.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
For optimal installation precision and stability, the holes for the four pins should adhere to a tolerance of H7. Additionally, ensuring the parallel alignment of the hole center with the main shaft center is crucial.

(II) Geometric Tolerance and Roughness Requirements
Compliance with national standards for geometric tolerance and roughness of both the center hole and keyway is imperative. The main shaft's geometric tolerance and roughness must also meet these stringent standards to enhance product performance and reliability.

(III) Installation Sequence Suggestions
Tailor the installation sequence to suit specific needs. Generally, it's advisable to first install the clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body for optimal efficiency.

(IV) Installation Notes for Square Pins
Square pins, designed to correct installation size discrepancies and account for thermal deformation due to clutch heating, require careful alignment. Ensure that the square pin's two flat surfaces are parallel to the radial direction of the ear plate for optimal performance.

(V) Sealing Requirements for Axial Air Intake
In cases of axial air intake, it is essential to fit sealing caps at both ends of the clutch to effectively prevent any air leakage, ensuring consistent performance.

(VI) Check after Installation
Post-installation, it is critical to verify that both the clutch end and brake end exhibit free movement. This ensures the clutch and brake functions operate smoothly and efficiently, maintaining system reliability.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every Kb2400 Pneumatic Clutch from Shandong Tenord Machinery Equipment Co., Ltd. is subjected to stringent quality checks. Customers must refrain from unauthorized disassembly, as it voids our responsibility for damages incurred. Should you encounter any quality issues, promptly notify us for swift resolution.

(II) Friction Pad Replacement Method
Our friction pads are wear items and require replacement after prolonged use when noticeable wear occurs. The replacement process is designed to be user-friendly, eliminating the need to disassemble ear plates or the clutch itself. Here's how you can effectively perform the replacement:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Next, remove the bolts and nuts securing the friction pads, install the new pads, and secure them by tightening the bolts and nuts.
- Replacement with Air Supply: Loosen the brake ear plate, then follow the aforementioned steps to install new friction pads efficiently.

(III) Timing for Friction Pad Replacement
- For machinery such as presses, if the equipment fails to achieve its rated capacity, inspect the friction pads for necessary replacement.
- As friction pads wear down to half of their original thickness, it is imperative to replace them promptly to maintain optimal performance.

VII. Product Selection
Selecting the right clutch is essential for ensuring the optimal function of your industrial equipment.
- Consequences of Improper Selection: An undersized clutch fails to meet capacity requirements, while an oversized clutch increases costs, risks overheating, accelerates pad wear, and hastens seal ring deterioration.
- Selection Suggestions: Refer to our comprehensive sample resources or consult our expert technicians for personalized selection advice designed to meet your specific needs.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
For your safety, avoid contact with the clutch during high-speed rotation to prevent accidents.

(II) Protection from High Temperature
Never touch the clutch immediately post-operation to prevent burns. Allow it to cool for half an hour to room temperature before any maintenance activities.

(III) Side Protection
Avoid standing beside the rotating clutch to prevent injury from flying debris. Ensure a protective cover is in place during operation for enhanced safety.

(IV) Attention during Ventilation Operation
During air-venting procedures, keep fingers clear of friction pads to prevent injury.

(V) Safety of Internal Structure
The clutch contains internal springs. Unauthorized disassembly poses safety risks and should only be performed by qualified professionals.
