(I) Application Fields
This versatile product has earned widespread acclaim and is extensively utilized in diverse industries, such as forging, printing, textile, welding, and shipbuilding. It shines particularly in areas like metal processing, paper processing machinery, woodworking machinery, and fiber machinery, consistently receiving high praise.

II. Product Advantages
(I) Compact Structure
- Minimal Axial Size and Lightweight: Its diminutive axial size and lightweight construction boast low inherent rotational inertia. This design effectively minimizes the overall volume and weight of the equipment while maintaining optimum performance, significantly enhancing operational efficiency.
(II) Safe and Reliable
- Asbestos-free Friction Material: Our friction material is entirely asbestos-free, eliminating potential health hazards associated with asbestos and aligning with contemporary environmental and safety standards. This ensures a safer, more reliable user experience.
(III) Easy Maintenance
- Effortless Friction Pad Replacement: Replacing friction pads is a breeze, requiring no clutch disassembly. This significantly cuts down on maintenance time and costs, boosts maintenance efficiency, and minimizes equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Innovative Disc Arc Design: The distinctive disc arc design greatly enhances the product's heat dissipation capacity, significantly lowering operational temperatures, extending product longevity, and ensuring stable operations during prolonged high-load conditions.
(V) Quick Response
- Rapid Clutching and Braking: Featuring a swift response speed, the system seamlessly performs clutching and braking functions, catering to various mechanical equipment's need for rapid responses and elevating production efficiency.
(VI) Diverse Connection Methods
- Adaptive Connection Options: With multiple versatile connection methods offering flexibility to suit different site requirements, the product demonstrates strong adaptability and harmonizes flawlessly with a wide range of equipment.


III. Product Structure
The pneumatic clutch brake is primarily composed of the following essential components:
- Clutch Body: Positioned on the main shaft of the equipment, the clutch body's center hole size can be customized to meet specific customer needs (refer to the sample for size range), serving as the clutch's core component.
- Clutch Ear Plate and Brake Ear Plate: Ingeniously connected to the flywheel and machine body through a quartet of robust pins, ensuring flawless stability and seamless operation of the clutch and brake system.
- Friction Pads (Blocks): These critical components are the heart of the clutching and braking mechanism, expertly managing the transmission and interruption of power with precision.
- Clutch Pins, Brake Pins, and Locking Plates: Crucial for connecting and securing various components. Ingeniously, the locking plates nestle into the pin grooves, securely fastened to the flywheel or machine body with screws, effectively preventing any axial movement.


IV. Working Principle
(I) Clutching Process
External compressed air elegantly enters the clutch cylinder via the intake hole, propelling the piston into motion. This action, facilitated by the friction pads, clutch body, and flat key, rotates the driven part, achieving seamless clutch engagement and enabling smooth power transmission.

(II) Braking Process
Upon halting the air supply, the piston gracefully shifts in reverse, powered by the spring's force. Through the friction pads, clutch body, and flat key, the driven part is swiftly braked in a mere 0.01 - 0.02 seconds, ensuring rapid equipment halt.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
The installation hole tolerance for the four pins is an impeccable H7, ensuring the hole center's parallelism to the main shaft center, thus guaranteeing precision and stability in pin installation.

(II) Geometric Tolerance and Roughness Requirements
Geometric tolerance and roughness for the center hole and keyway stringently adhere to national standards. The customer's main shaft must also meet these stringent standards to enhance overall product performance.

(III) Installation Sequence Suggestions
Customers have the flexibility to choose the installation sequence as per their specific circumstances. Generally, start with the installation of clutch and brake ear plates, pins, and locking plates, then seamlessly proceed to install the clutch brake body.

(IV) Installation Notes for Square Pins
Square pins are essential for correcting installation size discrepancies between two pins and mitigating plate thermal deformation from clutch heating. Ensure the flat surfaces of the square pin remain parallel to the radial direction of the ear plate.

(V) Sealing Requirements for Axial Air Intake
For axial air intake configurations, install sealing caps at both ends of the clutch to impeccably prevent any gas leakage.

(VI) Check after Installation
Post-installation, ensure the clutch end and brake end glide freely to guarantee the uninterrupted and optimal operation of the clutch and brake system.

Product Description

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each clutch supplied by Shandong Tenord Machinery Equipment Co., Ltd. is meticulously inspected to ensure top-notch quality. Customers are advised against unauthorized disassembly of the clutch, as it voids the warranty and the company shall not be liable for damages resulting from such actions. Should you encounter any quality issues, please promptly notify us, and we will address them at the earliest convenience.

(II) Friction Pad Replacement Method
The friction pads in the Versatile Clutch Brake Punching Machine are designed as consumable components and require timely replacement once the equipment has been extensively used, leading to significant wear. Our replacement process is streamlined and does not necessitate the dismantling of the ear plates or clutch. The detailed replacement procedure is as follows:
- Replacement without Air Supply: Begin by loosening the clutch ear plate, then remove the bolts and nuts securing the friction pads. Proceed by installing new friction pads, ensuring the bolts and nuts are firmly tightened.
- Replacement with Air Supply: Loosen the brake ear plate and follow the aforementioned steps to efficiently replace with new friction pads.

(III) Timing for Friction Pad Replacement
- For heavy-duty equipment such as presses, if the machine fails to achieve its rated capacity, it is essential to inspect the friction pads and ascertain if a replacement is necessary.
- Should the friction pads' wear exceed fifty percent compared to their original state, it is imperative for customers to promptly replace them to ensure optimal performance.

VII. Product Selection
Selecting the right clutch for your equipment is paramount, as it serves a vital role in the machinery's functionality.
- Consequences of Improper Selection: A clutch that is too small will fail to meet the machinery's rated capacity, whereas an oversized clutch will not only escalate equipment costs but also cause overheating, expediting the wear and tear of friction pads and the degradation of sealing rings.
- Selection Suggestions: Customers are encouraged to refer to our comprehensive company catalog or consult our expert technicians for personalized advice. We are committed to providing you with tailored, professional selection guidance.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
To ensure safety, it is absolutely forbidden to touch the clutch by hand or with any objects during its high-speed operation to prevent accidents.

(II) Protection from High Temperature
Avoid direct contact with the clutch immediately after it stops, as it remains extremely hot. Allow approximately thirty minutes for the clutch to cool to room temperature before commencing maintenance tasks.

(III) Side Protection
Standing beside a rotating clutch is highly discouraged to prevent injuries from potential debris. A protective cover is recommended to be installed around the clutch during operation.

(IV) Attention during Ventilation Operation
During the ventilation and air-stopping phases, it is crucial to avoid finger contact with the friction pads to prevent accidents like pinching.

(V) Safety of Internal Structure
The internal structure of the clutch includes springs and is not intended for unauthorized disassembly. Only qualified professionals should perform any necessary disassembly to ensure safety and prevent injury.
