(I) Application Fields
Widely acclaimed in industries like forging, printing, textiles, welding, and shipbuilding, this product garners exceptional reviews, especially in metal processing, paper machinery, woodworking, and fiber machinery sectors.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Light Weight: With a minimized axial size and reduced weight, it features low inherent rotational inertia. This effectively minimizes the volume and weight of equipment while maintaining performance, enhancing operational efficiency.
(II) Safe and Reliable
- Asbestos-free Friction Material: Composed without asbestos, this friction material eliminates potential health hazards and meets modern environmental and safety standards, offering users a secure and trustworthy experience.
(III) Easy Maintenance
- Effortless Friction Pad Replacement: Friction pads can be replaced effortlessly without dismantling the clutch, significantly reducing maintenance costs and time, boosting maintenance efficiency, and minimizing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Innovative Disc Arc Design: This unique design elevates heat dissipation capabilities, effectively managing operational temperature, extending product life, and ensuring equipment stability during prolonged high-load operations.
(V) Quick Response
- Rapid Clutching and Braking: Featuring a swift response time, it swiftly executes clutching and braking functions, catering to the need for quick action in various mechanical applications, and enhancing production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Equipped with multiple connection methods, it offers flexibility for different site requirements, boasting strong adaptability for seamless integration with diverse equipment.


III. Product Structure
The pneumatic clutch brake is composed of the following essential components:
- Clutch Body: Mounted on the equipment's main shaft, its center hole size is customizable per client specifications (refer to sample for size range), serving as the clutch's pivotal component.
- Clutch Ear Plate and Brake Ear Plate: Securely attached to the equipment's flywheel and body via four pins, ensuring consistent and stable clutch and brake operations.
- Friction Pads (Blocks): These essential components play a pivotal role in the clutching and braking processes, facilitating the seamless transmission and interruption of power. Their reliable performance ensures optimal functionality of the machinery.
- Clutch Pins, Brake Pins, and Locking Plates: Crucial for connecting and securing various machine components. The locking plates are expertly embedded within the pin grooves and robustly affixed to the flywheel or machine body with screws, effectively preventing any unwanted axial movement of the pins.


IV. Working Principle
(I) Clutching Process
When external compressed air enters the clutch cylinder via the intake hole, the piston is activated, propelling movement through the friction pads, clutch body, and flat key. This action rotates the driven part, achieving clutch engagement and enabling efficient power transmission.

(II) Braking Process
Upon halting the air supply, the piston is guided in the opposite direction by the spring's force. This mechanism, amplified by the friction pads, clutch body, and flat key, promptly brakes the driven part. The braking process is incredibly swift, requiring merely 0.01 - 0.02 seconds, ensuring rapid equipment stoppage.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Ensure the hole tolerance for inserting the four pins is H7, with the hole center aligned parallel to the main shaft center. This precision guarantees the pins' installation accuracy and stability.

(II) Geometric Tolerance and Roughness Requirements
Both the geometric tolerance and surface roughness of the center hole and keyway must adhere to stringent national standards. Correspondingly, the customer's main shaft must meet these requirements to enhance overall product performance.

(III) Installation Sequence Suggestions
Customers have flexibility in choosing their installation sequence based on specific circumstances. Typically, begin with installing the clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body.

(IV) Installation Notes for Square Pins
Square pins effectively mitigate installation size errors between two pins and compensate for thermal deformation of the plate due to clutch heating. Ensure the two flat surfaces of the square pin are precisely parallel to the radial direction of the ear plate for optimal performance.

(V) Sealing Requirements for Axial Air Intake
For systems with axial air intake, it is critical to install sealing caps at both ends of the clutch to prevent any gas leakage, safeguarding the system's integrity.

(VI) Check after Installation
Post-installation, verify that the clutch end and brake end exhibit free movement, ensuring smooth and reliable operation of the clutch and brake systems.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every clutch meticulously crafted by Shandong Tenord Machinery Equipment Co., Ltd. undergoes rigorous quality checks before reaching your hands. It is imperative for customers to refrain from unauthorized disassembly of the clutch. Our company disclaims any liability for damages resulting from such actions. Should you encounter any quality issues, we urge you to contact us promptly. Our dedicated team is committed to resolving your concerns without delay.

(II) Friction Pad Replacement Method
The friction pads are vital consumables, necessitating timely replacement after significant use to maintain optimal performance. The friction pad replacement process provided by our company is straightforward and does not involve disassembling the ear plates or clutch. Here's how you can proceed:
- Replacement without Air Supply: Start by loosening the clutch ear plate, then proceed to remove the bolts and nuts securing the worn friction pads. Install the new friction pads and ensure all bolts and nuts are securely tightened.
- Replacement with Air Supply: Begin by loosening the brake ear plate, then follow the aforementioned steps to replace the friction pads efficiently.

(III) Timing for Friction Pad Replacement
- For machines like presses, inspect the friction pads if the equipment fails to achieve its rated capacity, as this may indicate the need for replacement.
- Once the friction pads exhibit wear exceeding half of their original thickness, it's crucial for customers to replace them promptly to ensure consistent performance.

VII. Product Selection
Selecting the right clutch is paramount for your equipment's functionality. A precise choice ensures smooth operation, while an inappropriate selection can lead to inefficiencies.
- Consequences of Improper Selection: Choosing a clutch that's too small will not suffice for rated capacity; conversely, an oversized clutch inflates equipment costs and can cause overheating, accelerating friction pad wear and sealing ring degradation.
- Selection Suggestions: We encourage customers to explore our comprehensive samples or consult with our expert technicians for tailored advice. Our specialists are eager to guide you in making an informed decision.

VIII. Safety Precautions
(I) Protection during High - speed Rotation
To ensure safety, never attempt to touch the clutch or bring objects near it when it is rotating at high speeds, as this poses a significant danger.

(II) Protection from High Temperature
Avoid direct contact with the clutch immediately after it ceases rotation to prevent burns. Allow approximately 30 minutes for the clutch to cool to room temperature before conducting maintenance.

(III) Side Protection
It is critical to avoid standing beside a rotating clutch to prevent accidents from any potential debris. The use of protective covers around the clutch during operation is strongly recommended.

(IV) Attention during Ventilation Operation
During ventilation processes, abstain from making direct contact with the friction pads to prevent any risk of injury.

(V) Safety of Internal Structure
The clutch houses internal springs, and disassembly should only be performed by qualified professionals to avoid injury.
