(I) Application Fields
This product finds extensive application across industries such as forging, printing, textiles, welding, and shipbuilding. It garners exceptional acclaim, particularly within metal processing, paper processing machinery, woodworking machinery, and fiber machinery domains.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Lightweight: With a minimal axial profile and reduced weight, the product possesses low inherent rotational inertia. This compact, lightweight design minimizes equipment size and weight without sacrificing performance, thereby enhancing operational efficiency.
(II) Safe and Reliable
- Asbestos-free Friction Material: The friction material is engineered free of asbestos, eliminating potential health risks and conforming to modern environmental and safety standards, assuring users of a safe and reliable experience.
(III) Easy Maintenance
- Effortless Friction Pad Replacement: The design allows for easy replacement of friction pads without disassembling the clutch, significantly cutting down on maintenance time and expenses, enhancing maintenance efficiency, and reducing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Innovative Disc Arc Design: The cutting-edge disc arc design vastly augments the product's heat dissipation capacity, effectively lowering operational temperatures, extending product lifespan, and ensuring equipment stability during prolonged high-load operations.
(V) Quick Response
- Rapid Clutching and Braking: With an exceptionally fast response, it swiftly executes clutching and braking functions, catering to diverse mechanical equipment demands for quick reaction, thereby boosting production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Featuring a range of connection methods, it provides the flexibility to adapt to specific site requirements, showcasing robust adaptability and seamless compatibility with various equipment.


III. Product Structure
The pneumatic clutch brake is composed of the following integral components:
- Clutch Body: Mounted on the main shaft of the equipment, with a center hole size customizable per customer specifications (size range detailed in the sample); it is the clutch's pivotal component.
- Clutch Ear Plate and Brake Ear Plate: These crucial components effortlessly connect the flywheel to the machine body using four secure pins, ensuring the clutch and brake work in perfect harmony for a seamless operation.
- Friction Pads (Blocks): These essential elements are vital in the clutching and braking process, skillfully managing the transfer and interruption of power with remarkable precision.
- Clutch Pins, Brake Pins and Locking Plates: These components are fundamental for the secure connection and fixation of various parts. The locking plates, skillfully embedded in pin grooves, are fastened onto the flywheel or machine body with screws, effectively preventing any unwanted axial movement.


IV. Working Principle
(I) Clutching Process
External compressed air gracefully enters the clutch cylinder through the intake hole, prompting the piston into motion. The interaction of friction pads, clutch body, and flat key sets the driven part into rotation, thus achieving clutch engagement and seamless power transmission.

(II) Braking Process
Upon halting the air supply, the piston promptly moves backward, powered by the spring's force. This action, through friction pads, clutch body, and flat key, ensures the driven part is swiftly braked within an impressive time of just 0.01 - 0.02 seconds, allowing the equipment to stop instantly.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Precision is key—ensure the hole tolerance for installing the four pins is H7, with the hole center perfectly parallel to the main shaft center. This meticulous attention guarantees unparalleled installation accuracy and stability of the pins.

(II) Geometric Tolerance and Roughness Requirements
Adhering to strict national standards, the geometric tolerance and roughness of the center hole and keyway must be impeccable. Equally, the customer's main shaft should meet corresponding standards to significantly enhance product performance.

(III) Installation Sequence Suggestions
Customers may tailor the installation sequence to fit specific needs. Generally, it's recommended to first install the clutch and brake ear plates, followed by the pins and locking plates, before finally installing the clutch brake body.

(IV) Installation Notes for Square Pins
Square pins are ingeniously used to rectify installation size discrepancies of two pins and counteract plate thermal deformation from clutch heating. Ensure that the flat surfaces of the square pin align parallel to the radial direction of the ear plate for optimal performance.

(V) Sealing Requirements for Axial Air Intake
When axial air intake is involved, it is crucial to install sealing caps at both ends of the clutch. This preventive measure effectively averts any potential gas leakage.

(VI) Check after Installation
Conduct a thorough post-installation check to confirm that both the clutch end and brake end can move effortlessly, ensuring the flawless operation of the clutch and brake.

Product Description

VI. Product Maintenance
(I) Professional Maintenance Suggestions
At Shandong Tenord Machinery Equipment Co., Ltd., each Precision Clutch Brake Punching Machine is meticulously crafted and has undergone rigorous quality checks. We urge our esteemed customers to refrain from unauthorized disassembly of the clutch, as this could lead to damage for which the company cannot be held liable. Should any quality issues arise, we encourage prompt communication with us, and we promise a swift resolution to ensure your complete satisfaction.

(II) Friction Pad Replacement Method
Friction pads, being consumable components of our advanced machinery, require periodic replacement, especially after extensive use when significant wear is observed. The process of replacing these pads in our machines is streamlined and efficient, eliminating the need to dismantle ear plates or the clutch itself. Here's how to carry out the procedure seamlessly:
- Replacement without Air Supply: Begin by loosening the clutch ear plate, then proceed to remove the bolts and nuts securing the friction pads. Substitute them with new pads, and complete the process by securely tightening the bolts and nuts for optimal performance.
- Replacement with Air Supply: Follow the same initial step by loosening the brake ear plate, then repeat the bolt and nut removal and replacement process with new friction pads as previously described.

(III) Timing for Friction Pad Replacement
- In high-demand scenarios like press operations, a reduction in machine capacity could indicate the need for friction pad replacement.
- It's prudent to replace the friction pads promptly once their wear surpasses half of their original thickness to maintain equipment efficiency.

VII. Product Selection
Selecting the right clutch is pivotal for optimal functionality of your machinery. Our experts are here to guide you through this crucial decision.
- Consequences of Improper Selection: A clutch that is too small may falter under rated loads, while an excessively large clutch can inflate equipment costs. Additionally, it risks overheating, accelerating friction pad degradation, and hastening seal ring aging.
- Selection Suggestions: We invite you to explore our comprehensive selection guides or consult with our technical experts for tailored recommendations, ensuring you secure the ideal clutch for your specific needs.

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

(II) Protection from High Temperature
To prevent burns, never touch the clutch immediately after it ceases operation. Allow it to cool down for approximately 30 minutes before maintenance.

(III) Side Protection
Standing alongside a rotating clutch poses a risk of injury from ejected debris. Always ensure a protective cover is in place during operation.

(IV) Attention during Ventilation Operation
During the ventilation cycle, keep fingers clear of friction pads to avoid injury.

(V) Safety of Internal Structure
Our clutches incorporate internal springs, necessitating professional disassembly to prevent injury. Unauthorized attempts should be avoided.
