(VI) Diverse Connection Methods
- Flexible Connection Options: With multiple connection methods available, it offers flexibility to adapt to various site requirements, ensuring it fits seamlessly with diverse equipment setups.


III. Product Structure
The pneumatic clutch brake is composed of these key components:
- Clutch Body: This component is installed on the equipment's main shaft, with a customizable center hole size based on customer specifications (refer to the sample size range). It serves as the clutch's core element.
- Clutch Ear Plate and Brake Ear Plate: These are ingeniously connected to the flywheel and the machine body of the equipment using four robust pins. This clever design ensures the clutch and brake operate with unwavering stability.
- Friction Pads (Blocks): These vital components play a pivotal role in the clutching and braking process, enabling the seamless transmission and interruption of power with ease.
- Clutch Pins, Brake Pins, and Locking Plates: Essential for connecting and securing various components. Notably, the locking plates are expertly embedded in the pin grooves and firmly affixed to the flywheel or machine body using screws, effectively preventing any axial movement of the pins.


IV. Working Principle
(I) Clutching Process
External compressed air is introduced into the clutch cylinder via the intake hole, driving the piston into action. This movement, through friction pads, the clutch body, and a flat key, rotates the driven part, thus achieving clutch engagement and facilitating the smooth transmission of power.

(II) Braking Process
Upon ceasing the air supply, the piston is propelled in the opposite direction by the spring's force. This swift action, through friction pads, the clutch body, and a flat key, promptly brakes the driven part. The braking action is remarkably swift, taking only 0.01 - 0.02 seconds, ensuring the equipment comes to a rapid halt.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
The precise hole tolerance for installing the four pins should adhere to H7 specifications. Furthermore, the hole center must be meticulously parallel to the main shaft center, guaranteeing the installation accuracy and the enduring stability of the pins.

(II) Geometric Tolerance and Roughness Requirements
Adherence to national standards for the geometric tolerance and roughness of the center hole and keyway is non-negotiable. Additionally, the geometric tolerance and roughness of the customer's main shaft should align with the specified requirements to significantly enhance product performance.

(III) Installation Sequence Suggestions
Customers have the flexibility to choose the installation sequence based on specific conditions. Typically, it is advisable to commence with the installation of the clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body.

(IV) Installation Notes for Square Pins
Square pins are ingeniously used to mitigate the installation size discrepancies of two pins and the thermal deformation of the plate caused by clutch heating. It is crucial to ensure that the two flat surfaces of the square pin are aligned parallel to the radial direction of the ear plate.

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

(VI) Check after Installation
Post-installation, verify that the clutch end and brake end move smoothly and freely. This ensures the flawless and reliable operation of the clutch and brake system.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every Kb600 Pneumatic Clutch from Shandong Tenord Machinery Equipment Co., Ltd. has passed rigorous quality inspections to ensure top-notch performance. It is crucial to avoid any unauthorized disassembly, as this could lead to damage for which the company cannot be held accountable. Should any quality issues arise, please notify us promptly. Our dedicated team is committed to resolving any concerns swiftly and efficiently, ensuring your machinery functions seamlessly.

(II) Friction Pad Replacement Method
The friction pads are essential components that may require replacement after extended use due to wear. Our innovative design allows for a straightforward replacement process, eliminating the need to dismantle the ear plates or clutch. Follow these simple steps for hassle-free maintenance:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Remove the bolts and nuts that secure the friction pads, swap in the fresh pads, and then carefully tighten the bolts and nuts to ensure a secure fit.
- Replacement with Air Supply: Simply loosen the brake ear plate and replicate the previous steps to refresh the friction pads with ease.

(III) Timing for Friction Pad Replacement
- For machinery like presses, if it fails to achieve its rated capacity, inspect the friction pads for wear and replace them as necessary to restore optimum performance.
- When the friction pads have worn down to more than half their original thickness, timely replacement is recommended to maintain performance and ensure safety.

VII. Product Selection
Selecting the ideal clutch for your equipment is paramount to ensuring its full functionality and efficiency.
- Consequences of Improper Selection: Choosing a clutch that's too small won't meet capacity needs, while an oversized clutch can inflate costs, cause overheating, accelerate friction pad wear, and hasten seal ring aging.
- Selection Suggestions: Refer to our company's comprehensive samples or reach out to our experienced technicians for personalized consultation. We pledge to provide expert guidance tailored to your specific requirements.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
Never touch the clutch or introduce foreign objects while it is in high-speed rotation. This precaution is vital to safeguard against potential hazards.

(II) Protection from High Temperature
Avoid direct contact with the clutch instantly after it has ceased rotation to prevent burns. Allow approximately 30 minutes for the clutch to cool to room temperature before undertaking any maintenance activities.

(III) Side Protection
Refrain from standing alongside the rotating clutch to avert accidents caused by flying debris. Always ensure a protective cover is fitted during operation for added safety.

(IV) Attention during Ventilation Operation
During ventilation and air cut-off processes, strictly avoid contact with the friction pads to prevent injury from pinching.

(V) Safety of Internal Structure
The internal springs of the clutch are critical components. Unauthorized disassembly can pose injury risks and should only be performed by qualified professionals.
