(I) Application Fields
This product finds extensive application across industries like forging, printing, textiles, welding, and shipbuilding. It has garnered exceptional acclaim in niches such as metal processing, paper processing machinery, woodworking machinery, and fiber machinery, thanks to its superior performance.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Lightweight: The product boasts a diminutive axial size and featherlight weight, coupled with minimal inherent rotational inertia. These attributes effectively reduce the overall volume and weight of the equipment, maintaining performance while boosting operational efficiency dramatically.
(II) Safe and Reliable
- Asbestos-free Friction Material: The friction material is meticulously engineered to exclude asbestos components, circumventing potential health risks associated with asbestos. It aligns with modern environmental and safety norms, offering users a safer, more reliable experience.
(III) Easy Maintenance
- Effortless Friction Pad Replacement: The friction pads can be replaced with ease, without dismantling the clutch, significantly slashing maintenance costs and time. This enhances maintenance efficiency and minimizes equipment downtime remarkably.
(IV) Excellent Heat Dissipation Performance
- Innovative Disc Arc Design: The distinct disc arc design greatly enhances the product's heat dissipation capacity, reducing operational temperatures. This extends the product's lifecycle and ensures equipment stability, even during prolonged high-load operations.
(V) Quick Response
- Rapid Clutching and Braking: With an impressively swift response, it promptly executes clutching and braking functions. This meets the quick response requirements of various mechanical systems, substantially boosting production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: The product is equipped with multiple adaptable connection methods, allowing for flexible selection based on site requirements. It demonstrates strong versatility and the capability to integrate seamlessly with diverse equipment types.


III. Product Structure
The pneumatic clutch brake is ingeniously constructed from the following key components:
- Clutch Body: Mounted on the equipment's main shaft, with a customizable center hole size to meet specific customer requirements (size range available in the sample), serving as the clutch's pivotal element.
- Clutch Ear Plate and Brake Ear Plate: Ingeniously connected to the flywheel and machine body of the equipment respectively through four robust pins, ensuring the unwavering stability and seamless operation of the clutch and brake.
- Friction Pads (Blocks): These pivotal components play a crucial role in the clutching and braking process, expertly facilitating the transmission and interruption of power with precision.
- Clutch Pins, Brake Pins and Locking Plates: Essential for the secure connection and fixation of various components. Notably, the locking plates are meticulously embedded in the pin grooves and are firmly fixed on the flywheel or machine body with screws to decisively prevent axial movement of the pins.


IV. Working Principle
(I) Clutching Process
External compressed air majestically enters the clutch cylinder through the intake hole, propelling the piston to move. Through the friction pads, clutch body, and flat key, the driven part is set into motion to accomplish clutch engagement, thereby seamlessly enabling the transmission of power.

(II) Braking Process
Upon halting the air supply, the piston is prompted to move in the opposite direction under the spring's influence. Through the friction pads, clutch body, and flat key, the driven part is swiftly braked. With a breathtaking braking time of merely 0.01 - 0.02 seconds, the equipment is ensured to stop promptly and reliably.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
The hole tolerance for installing the four pins should be H7, while ensuring that the hole center is perfectly parallel to the main shaft center, thereby guaranteeing the 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 meticulously required to comply with national standards. Furthermore, the geometric tolerance and roughness of the customer's main shaft must also meet the corresponding requirements, significantly enhancing product performance.

(III) Installation Sequence Suggestions
Customers are at liberty to choose the installation sequence based on specific conditions. Typically, it is recommended to install the clutch and brake ear plates, pins, and locking plates first, followed by the installation of the clutch brake body.

(IV) Installation Notes for Square Pins
Square pins are ingeniously designed to obliterate the installation size error of two pins and to counteract the plate's thermal deformation induced by clutch heating. It is imperative to 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, it is crucial to install sealing caps at both ends of the clutch to impeccably prevent any gas leakage.

(VI) Check after Installation
Post-installation, it is essential to ensure that the clutch end and brake end move freely, thus guaranteeing the smooth and normal operation of the clutch and brake.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each clutch from Shandong Tenord Machinery Equipment Co., Ltd. is subjected to rigorous quality control before reaching your hands. Customers are advised against unauthorized disassembly as it voids responsibility for damages. Encounter any quality issues? Promptly notify us, and we pledge swift resolution.

(II) Friction Pad Replacement Method
Our Durable Clutch Brake Punching Machine features friction pads that naturally wear over time. When heavily used, these consumable components must be replaced to maintain optimal functionality. We ensure ease of replacement without the need to dismantle ear plates or clutches, following these simple steps:
- 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 pads, and then retighten the bolts and nuts securely.
- Replacement with Air Supply: Loosen the brake ear plate and proceed as described above to ensure seamless replacement of the friction pads.

(III) Timing for Friction Pad Replacement
- For machines like presses, if they fall short of their rated capacity, inspect the friction pads for necessary replacement.
- Once friction pad wear exceeds 50% of their original state, timely replacement is recommended to preserve equipment efficiency.

VII. Product Selection
Selecting the right clutch is vital for the superior performance of your equipment. Choose wisely!
- Consequences of Improper Selection: Oversized clutches escalate costs and can overheat, leading to accelerated wear and tear. Undersized options fall short of capacity demands.
- Selection Suggestions: Explore our comprehensive samples or consult our expert technicians. We are dedicated to providing you with informed, professional guidance tailored to your needs.

VIII. Safety Precautions
(I) Protection during High - speed Rotation
To ensure safety, never touch the clutch or allow objects near it during high-speed rotation to prevent accidents.

(II) Protection from High Temperature
After operation, avoid touching the clutch immediately as it may cause burns. Ensure a cooling period of approximately 30 minutes before any maintenance work.

(III) Side Protection
Standing beside a spinning clutch is hazardous due to potential debris. Always equip the machine with a protective cover for safe operation.

(IV) Attention during Ventilation Operation
Exercise caution during ventilation. Avoid contact with friction pads to prevent injury.

(V) Safety of Internal Structure
The clutch contains internal springs. Unauthorized disassembly is dangerous and should be avoided. Only professionals should undertake such tasks for safety.
