(I) Application Fields
Our product finds extensive applications in industries such as forging, printing, textile, welding, and shipbuilding. It garners acclaim, particularly in fields like metal processing, paper processing machinery, woodworking machinery, and fiber machinery.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Light Weight: With a minimized axial size and reduced weight, this component features low inherent rotational inertia, effectively decreasing the overall volume and weight of the equipment. This optimization ensures performance efficacy while enhancing operational efficiency.
(II) Safe and Reliable
- Asbestos-Free Friction Material: The friction material is free of asbestos, eliminating potential health risks and satisfying modern environmental and safety standards. Users can expect a safer, more reliable experience.
(III) Easy Maintenance
- Simple Friction Pad Replacement: The straightforward replacement of friction pads requires no disassembly of the clutch, significantly cutting down maintenance costs and time. This improves equipment maintenance efficiency and minimizes downtime.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: The distinctive disc arc design enhances heat dissipation, effectively reducing operational temperatures, prolonging product life, and maintaining equipment stability during extended high-load operations.
(V) Quick Response
- Fast Clutching and Braking: Exhibiting rapid response times, this system swiftly executes clutching and braking functions, catering to the quick response demands of various mechanical equipment, thereby boosting production efficiency.
(VI) Diverse Connection Methods
- Flexible Connection Options: Featuring multiple connection methods, this product offers flexibility to meet diverse site requirements with ease, ensuring strong adaptability and seamless compatibility with a variety of equipment.


III. Product Structure
The pneumatic clutch brake comprises several integral components:
- Clutch Body: Mounted on the main shaft of the equipment, the center hole size is customizable to client specifications (size range available in the sample), and it serves as the pivotal component of the clutch.
- Clutch Ear Plate and Brake Ear Plate: Ingeniously connected to the flywheel and machine body of the equipment through four robust pins, ensuring the seamless and stable operation of both the clutch and the brake.
- Friction Pads (Blocks): They are instrumental in the clutching and braking process, expertly facilitating the transmission and interruption of power with precision.
- Clutch Pins, Brake Pins, and Locking Plates: These components are essential for the secure connection and fixation of various parts. Notably, the locking plates are meticulously embedded in the pin grooves and firmly fixed on the flywheel or machine body with screws to prevent any axial pin movement.


IV. Working Principle
(I) Clutching Process
External compressed air gracefully enters the clutch cylinder through the intake hole, propelling the piston into motion. This movement, via the friction pads, clutch body, and flat key, rotates the driven part to achieve clutch engagement, thus enabling efficient power transmission.

(II) Braking Process
Upon halting the air supply, the piston swiftly moves in the reverse direction due to the spring's force. Through the friction pads, clutch body, and flat key, the driven part is promptly braked, achieving a rapid stop within 0.01 - 0.02 seconds, ensuring quick cessation of equipment operation.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
The hole tolerance for the installation of the four pins should be H7, with the hole center meticulously aligned parallel to the main shaft center, ensuring the precision and stability of pin installation.

(II) Geometric Tolerance and Roughness Requirements
The geometric tolerance and roughness of the center hole and keyway must strictly adhere to national standards. Additionally, the geometric tolerance and roughness of the customer's main shaft should meet these standards to enhance product performance.

(III) Installation Sequence Suggestions
Customers have the flexibility to choose the installation sequence based on their needs. Typically, it is advisable to first install 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 designed to eliminate any installation size errors between two pins and mitigate plate thermal deformation caused by clutch heating. Ensure that the two flat surfaces of the square pin are parallel to the radial direction of the ear plate.

(V) Sealing Requirements for Axial Air Intake
For axial air intake systems, ensure the installation of 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 can move freely to guarantee the optimal operation of the clutch and brake systems.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every clutch from Shandong Tenord Machinery Equipment Co., Ltd. undergoes rigorous quality assurance tests. Disassembling the clutch without authorization invalidates our warranty, as we cannot be liable for damages resulting from private tampering. Should you encounter any issues, promptly contact us for swift resolution, ensuring your operations continue seamlessly.

(II) Friction Pad Replacement Method
Friction pads, being consumables, require timely replacement after extensive use to maintain optimal performance. Our design allows for easy replacement without the need to disassemble ear plates or the clutch, streamlining maintenance efforts. Here's how to proceed:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Proceed to unfasten the bolts and nuts securing the friction pads, swap in brand new friction pads, and securely retighten the bolts and nuts.
- Replacement with Air Supply: Loosen the brake ear plate and follow the same straightforward steps to refresh your friction pads.

(III) Timing for Friction Pad Replacement
- If your machinery, such as presses, fails to achieve the specified capacity, inspect the friction pads as a potential solution.
- Once friction pad wear surpasses half of their original thickness, it's crucial to replace them promptly to prevent operational inefficiencies.

VII. Product Selection
Selecting the perfect clutch is pivotal for the efficient functioning of your equipment. A well-suited clutch assures reliability and performance.
- Consequences of Improper Selection: An undersized clutch won't meet capacity demands. Conversely, an oversized one inflates costs and risks overheating, accelerating friction pad degradation and seal ring aging.
- Selection Suggestions: Explore our comprehensive sample range or consult our expert technicians for tailored selection guidance. We are committed to equipping you with the right solutions.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
Never touch the clutch or allow objects near it while it is spinning at high velocity, as this could lead to serious hazards.

(II) Protection from High Temperature
Avoid direct contact with the clutch immediately after it ceases operation due to potential burns. Allow approximately 30 minutes for it to cool to ambient temperature before conducting any form of maintenance.

(III) Side Protection
Steer clear of the clutch's rotational path to prevent accidents from debris. Always utilize a protective cover during its operation to safeguard against unforeseen incidents.

(IV) Attention during Ventilation Operation
During the ventilation and deactivation stages, refrain from touching the friction pads with your fingers to prevent pinching injuries.

(V) Safety of Internal Structure
The clutch contains spring mechanisms for its operation. Unauthorized disassembly is dangerous and must be avoided. Seek professional assistance for any internal assessments or repairs.
