(VI) Diverse Connection Methods
- Versatile Connection Options: Featuring multiple connection methods that can be flexibly selected based on specific site requirements, it offers robust adaptability and the capability to perfectly integrate with various equipment types.


III. Product Structure
The pneumatic clutch brake is primarily composed of the following essential components:
- Clutch Body: Mounted on the main shaft of the equipment, with a customizable center hole size according to customer specifications (refer to sample size range), it serves as the clutch's core component.
- Clutch Ear Plate and Brake Ear Plate: Meticulously connected to the flywheel and machine body of the equipment via four robust pins, these components ensure the seamless and stable operation of the clutch and brake, providing unparalleled reliability and performance.
- Friction Pads (Blocks): These essential components drive the magic behind the clutching and braking process, masterfully facilitating the transmission and interruption of power for smooth machine operation.
- Clutch Pins, Brake Pins, and Locking Plates: These crucial elements are ingeniously designed for the precise connection and fixation of various components. The locking plates, expertly embedded in the pin grooves, are securely fixed on the flywheel or machine body with screws to prevent any unwanted axial movement, ensuring steadfast stability.


IV. Working Principle
(I) Clutching Process
The clutching process unfolds as external compressed air gracefully enters the clutch cylinder through the intake hole, propelling the piston into motion. With the friction pads, clutch body, and flat key working in harmony, the driven part rotates effortlessly to achieve clutch engagement, thus enabling a powerful and smooth transmission of power.

(II) Braking Process
In the braking process, once the air supply ceases, the spring's force skillfully nudges the piston in the reverse direction. This movement, together with the friction pads, clutch body, and flat key, allows the driven part to be swiftly braked. The entire process takes a mere 0.01 - 0.02 seconds, ensuring the equipment halts promptly and efficiently.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
The hole tolerance for installing the four pins must adhere to an H7 specification, with the hole center being parallel to the main shaft center. This precision ensures the flawless installation accuracy and enduring stability of the pins.

(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 should meet these exacting requirements to elevate the product's performance to new heights.

(III) Installation Sequence Suggestions
Customers are encouraged to tailor the installation sequence to their specific needs. Generally, begin with the installation of the clutch and brake ear plates, followed by the pins and locking plates, and finally secure the clutch brake body for optimal performance.

(IV) Installation Notes for Square Pins
Square pins are ingeniously employed to counteract installation size discrepancies between two pins and mitigate plate thermal deformation due to clutch heating. It is essential that the two flat surfaces of the square pin remain parallel to the radial direction of the ear plate for impeccable functionality.

(V) Sealing Requirements for Axial Air Intake
For axial air intake configurations, be sure to install sealing caps at both ends of the clutch to effectively prevent gas leakage, ensuring optimal performance and longevity.

(VI) Check after Installation
Post-installation, verify that the clutch and brake ends move with absolute freedom to guarantee the seamless operation and efficiency of the clutch and brake systems.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each Kb300 Air Clutch Brake we offer has passed rigorous inspections to ensure the highest standards of quality and performance. We strongly advise against any attempts to disassemble the clutch independently, as unauthorized tampering could lead to damage for which we cannot assume responsibility. Should you encounter any quality issues, please notify us promptly. Our dedicated team will provide swift solutions to address your concerns and ensure optimal functioning of your equipment.

(II) Friction Pad Replacement Method
Friction pads, being integral yet consumable components of the product, require timely attention and replacement, especially after prolonged usage as they wear down. The remarkable design of our clutch allows for an uncomplicated replacement process-disassembly of ear plates and the clutch itself is not needed. Here are the straightforward methods to ensure continued efficiency:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Carefully remove the bolts and nuts securing the worn friction pads, replace them with fresh ones, and secure by tightening the bolts and nuts firmly.
- Replacement with Air Supply: Loosen the brake ear plate and proceed with the same simplification method as above to replace the friction pads effectively.

(III) Timing for Friction Pad Replacement
- For presses and similar equipment, a drop below the machine's rated capacity is a clear indicator that the friction pads should be checked and potentially replaced.
- When you've observed that the wear of the friction pads is more than half of their original state, it is imperative to replace them promptly to maintain the machine's efficiency.

VII. Product Selection
Choosing the right clutch is critical to the seamless operation of your equipment, as it serves as a pivotal functional component.
- Consequences of Improper Selection: Selecting a clutch that is too small can result in insufficient power, failing to meet the equipment's rated capacity. Conversely, an oversized clutch not only escalates equipment costs but also risks overheating, which in turn accelerates the wear of friction pads and the degradation of sealing rings.
- Selection Suggestions: Customers are encouraged to reference our comprehensive samples or directly consult with our expert technicians. Our commitment is to furnish you with tailored, professional selection advice that aligns perfectly with your operational needs.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
Ensure utmost safety by refraining from touching the clutch or bringing objects near it while it is in high-speed rotation, as this poses a significant risk of injury.

(II) Protection from High Temperature
After the clutch halts, avoid immediate contact with it to prevent burns. Allow a cooling period of approximately half an hour post-operation to ensure it returns to a safe, ambient temperature before performing any maintenance activities.

(III) Side Protection
Stay clear of standing beside the rotating clutch to prevent incidents caused by flying debris. It's essential to install a protective cover over the clutch during operation to enhance safety.

(IV) Attention during Ventilation Operation
During the processes of ventilation and halting air supply, avoid placing fingers near the friction pads to prevent the risk of pinching or injury.

(V) Safety of Internal Structure
The clutch's interior houses springs; therefore, unauthorized disassembly is discouraged as it could result in personal injury. Any necessary disassembling should strictly be entrusted to qualified professionals.
