(VI) Diverse Connection Methods
- Versatile Connection Options: Offering diverse connection methods, it can be adeptly tailored to fit different site requirements, showcasing exceptional adaptability and ensuring seamless integration with a wide array of equipment.


III. Product Structure
The core components of the pneumatic clutch brake include:
- Clutch Body: Mounted on the main shaft of equipment, with a customizable center hole size tailored to client specifications (refer to sample for size range), serving as the clutch's vital component.
- Clutch Ear Plate and Brake Ear Plate: Each of these crucial components is meticulously linked to the flywheel and the machine body using four precision-engineered pins. This sophisticated connection ensures unwavering stability during the clutch's and brake's operation, providing seamless performance for the equipment.
- Friction Pads (Blocks): These essential components serve as the heart of the clutch and braking process. They are instrumental in realizing both the seamless transmission and the precise interruption of power, ensuring impeccable functionality.
- Clutch Pins, Brake Pins, and Locking Plates: These components are vital for the secure connection and immobilization of various parts. The locking plates are skillfully embedded within pin grooves and affixed to the flywheel or machine body using screws, effectively preventing any unwanted axial movement of the pins.


IV. Working Principle
(I) Clutching Process
As external compressed air gracefully enters the clutch cylinder through the strategically designed intake hole, the piston is urged into action. This movement, in concert with the friction pads, clutch body, and flat key, instigates the rotation of the driven part. The result? A flawless clutch engagement that facilitates the seamless transmission of power.

(II) Braking Process
Upon cessation of the air supply, the piston is compelled to retract under the spring's influence. This action, combined with the friction pads, clutch body, and flat key, swiftly brings the driven part to a halt. The braking process occurs in a mere heartbeat, 0.01 - 0.02 seconds, assuring rapid stoppage and unrivaled safety for the machinery.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
To achieve unparalleled installation accuracy and ensure the robust stability of the pins, the hole tolerance for these installations must be precisely H7. Furthermore, the hole center should be impeccably parallel to the main shaft center, guaranteeing flawless alignment and operation.

(II) Geometric Tolerance and Roughness Requirements
Adhering to national standards for geometric tolerance and roughness of center holes and keyways is imperative. The main shaft's geometric tolerance and roughness should also meet these stringent requirements, enhancing both the product's performance and longevity.

(III) Installation Sequence Suggestions
While the installation sequence may vary based on individual circumstances, a recommended approach is to first install the clutch and brake ear plates, pins, and locking plates. Following this, one should proceed with the installation of the clutch brake body, ensuring a methodical and efficient setup.

(IV) Installation Notes for Square Pins
Square pins serve the critical function of compensating for installation size discrepancies between two pins, as well as mitigating plate deformation due to clutch heating. It's essential to ensure that the two flat surfaces of the square pin are aligned parallel to the radial direction of the ear plate, promoting optimal performance.

(V) Sealing Requirements for Axial Air Intake
In cases of axial air intake, the installation of sealing caps at both ends of the clutch is crucial, effectively preventing any potential gas leakage and ensuring a secure and efficient operation.

(VI) Check after Installation
Post-installation, it is vital to ascertain that both the clutch end and brake end move effortlessly. This ensures that the clutch and brake are functioning optimally, providing peace of mind and reliable performance for the long haul.

VI. Product Maintenance
(I) Expert Maintenance Recommendations
Every clutch from Shandong Tenord Machinery Equipment Co., Ltd., including the Kb2900 Air Brake for Advanced Mechanical Press Machinery, is rigorously tested to ensure quality. Customers are advised against any unauthorized disassembly of the clutch, as any resulting damage will not be eligible for company compensation. For any quality concerns, promptly reach out to us, and we will address your issues swiftly and efficiently.

(II) Method for Replacing Friction Pads
Friction pads are essential consumable components of our products and must be replaced after extensive use and significant wear. The process for replacing friction pads is streamlined and does not require disassembly of the ear plates or clutch. Follow these simple steps for replacement:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Proceed to remove the bolts and nuts securing the friction pads, replace them with new ones, and securely tighten the bolts and nuts.
- Replacement with Air Supply: Loosen the brake ear plate and follow the same steps for friction pad replacement, ensuring a seamless process.

(III) Optimal Timing for Friction Pad Replacement
- In equipment such as presses, if the machine fails to achieve its rated capacity, inspect the friction pads and replace them if necessary.
- When friction pad wear exceeds half of their original thickness, timely replacement is prudent to maintain peak performance.

VII. Product Selection
Selecting the right clutch for your equipment is paramount to its function and efficiency.
- Consequences of Improper Selection: A clutch that's too small will fail to meet capacity standards, whereas an oversized clutch will inflate costs, risk overheating, and hasten the wear of friction pads and sealing ring degradation.
- Selection Suggestions: Choose from our comprehensive samples or consult with our expert technicians for tailored advice. We offer professional guidance to ensure the perfect fit for your needs.

VIII. Safety Precautions
(I) Precautions during High-speed Rotation
Avoid direct contact with the clutch or any object when it is spinning at high speeds to ensure utmost safety.

(II) Protection from Excessive Heat
Refrain from touching the recently stopped clutch with bare hands to prevent burns. Allow about 30 minutes for it to cool to room temperature before maintenance.

(III) Lateral Protection Measures
Standing beside a spinning clutch is strictly prohibited to mitigate risk from potential flying debris. Ensure a protective cover is fitted during operation.

(IV) Caution during Ventilation Operations
During the processes of ventilation and air cessation, do not touch the friction pads with fingers to prevent injury.

(V) Security of Internal Mechanisms
With its internal spring mechanisms, the clutch should never be disassembled by untrained individuals to avoid harm. Professional intervention is required for any disassembly.
