Our product finds extensive application in industries such as forging, printing, textile, welding, and shipbuilding. It has garnered substantial acclaim, especially in metal processing, paper processing machinery, woodworking machinery, and fiber machinery sectors.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Light Weight: Boasting a compact axial dimension and lightweight profile, it minimizes rotational inertia, effectively shrinking the overall volume and weight of equipment without compromising performance, thereby boosting operational efficiency.
(II) Safe and Reliable
- Asbestos-Free Friction Material: Crafted with asbestos-free friction material, it eliminates potential health hazards associated with asbestos, aligning with contemporary environmental and safety standards for a safer, more reliable user experience.
(III) Easy Maintenance
- Effortless Friction Pad Replacement: Replacing friction pads is a breeze and does not necessitate disassembling the clutch, significantly cutting down on maintenance time and costs while enhancing maintenance efficiency and reducing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: The distinctive disc arc design greatly enhances the product's heat dissipation capacity, effectively managing operational temperatures, extending product longevity, and ensuring equipment stability during prolonged high-load operations.
(V) Quick Response
- Fast Clutching and Braking: Featuring a rapid response rate, it swiftly executes clutching and braking functions, addressing the quick response demands of various mechanical equipment and boosting production efficiency.
(VI) Diverse Connection Methods
- Flexible Connection Options: With multiple adaptable connection methods, it can be tailored to diverse site requirements, offering robust adaptability and the perfect match for varying equipment.


III. Product Structure
The pneumatic clutch brake is ingeniously composed of the following essential components:
- Clutch Body: Mounted on the equipment's main shaft, its center hole size is customizable as per customer specifications (see the sample for size range). It serves as the clutch's core component.
- Clutch Ear Plate and Brake Ear Plate: Securely attached to the equipment's flywheel and body through four pins, they ensure the clutch and brake operate stably.
- Friction Pads (Blocks): These components are integral to the clutching and braking mechanisms, masterfully facilitating the seamless transmission and disruption of power. Their precision engineering ensures optimal performance in high-demand settings.
- Clutch Pins, Brake Pins and Locking Plates: Essential for the firm connection and stabilization of various components. The locking plates are innovatively embedded within the pin grooves and are securely fastened to the flywheel or machine body, preventing any unwanted axial pin movement, thus enhancing reliability.


IV. Working Principle
(I) Clutching Process
External compressed air is introduced into the clutch cylinder via a precision-engineered intake hole, driving the piston into motion. This interaction with friction pads, the clutch body, and a flat key facilitates the rotation of the driven component, achieving efficient clutch engagement and seamless power transmission.

(II) Braking Process
Upon cessation of air supply, the piston is expertly guided by the spring to retract, engaging the friction pads, clutch body, and flat key, to swiftly decelerate the driven component. Remarkably, the braking process is completed within a rapid 0.01 - 0.02 seconds, guaranteeing the equipment's immediate halt with unmatched precision.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
The installation precision for the four pins demands a hole tolerance of H7. Alignment of the hole center with the main shaft center is critical to ensure superior installation accuracy and stability, which are vital for the product's long-term performance.

(II) Geometric Tolerance and Roughness Requirements
The central hole and keyway must adhere to rigorous national standards regarding geometric tolerance and roughness. Moreover, the customer's main shaft should match these stringent requirements to elevate the product's operational efficacy.

(III) Installation Sequence Suggestions
Customers are encouraged to adapt the installation sequence based on their specific scenarios. Typically, it is advisable to commence with the clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body, ensuring a logical and efficient setup process.

(IV) Installation Notes for Square Pins
Square pins are ingeniously designed to correct installation size discrepancies of two pins and counteract the plate's thermal deformation due to clutch heating. It is crucial that the two flat surfaces of the square pin maintain parallel alignment with the radial orientation of the ear plate to ensure precision.

(V) Sealing Requirements for Axial Air Intake
For axial air intake systems, it is mandatory to install robust sealing caps at both ends of the clutch. This precautionary measure is vital to prevent any potential gas leakage, thereby maintaining the integrity of the system.

(VI) Check after Installation
Following installation, it is imperative that both the clutch end and brake end exhibit unimpeded movement. This ensures the flawless functioning of the entire clutch and brake system, securing optimal performance and reliability.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every clutch that leaves Shandong Tenord Machinery Equipment Co., Ltd. is meticulously inspected to ensure top-notch quality. We advise against disassembling the clutch on your own as unauthorized tampering can lead to damage for which we cannot assume responsibility. Should any quality issues arise, please contact us promptly, and we will resolve your concerns swiftly and efficiently.

(II) Friction Pad Replacement Method
Friction pads are vital components that naturally wear down over time. When you notice significant wear, timely replacement is essential. The process is designed to be straightforward, eliminating the need to disassemble ear plates or the clutch. Here's how you can easily replace friction pads:
- Replacement without Air Supply: Simply loosen the clutch ear plate, remove the bolts and nuts securing the friction pads, swap in new pads, and ensure all bolts and nuts are tightened securely.
- Replacement with Air Supply: Follow the same uncomplicated steps by loosening the brake ear plate, then proceed to replace with new friction pads as described.

(III) Timing for Friction Pad Replacement
- For high-demand machinery like presses, if the machine's performance falls short of its rated capacity, inspect the friction pads for possible replacement.
- It's imperative to replace the friction pads promptly once wear exceeds half of their original thickness to maintain optimal performance and safety.

VII. Product Selection
Selecting the right clutch is critical to the optimal performance of your equipment.
- Consequences of Improper Selection: A clutch that's too small won't meet required capacity, whereas one that's oversized can unnecessarily escalate costs, potentially lead to overheating, and speed up the wear of friction pads and sealing ring deterioration.
- Selection Suggestions: Customers are encouraged to refer to our detailed samples or consult with our expert technicians. We are committed to delivering personalized and professional recommendations tailored to your specific needs.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
For your safety, never make contact with the clutch or nearby objects while it is in high-speed rotation to prevent any hazardous situations.

(II) Protection from High Temperature
Avoid direct contact with the clutch immediately after use as it retains heat. Allow a cool-down period of approximately 30 minutes until the temperature normalizes to safeguard against burns during maintenance.

(III) Side Protection
Standing beside an operating clutch is dangerous. Install a protective cover to shield against potential accidents caused by dislodged materials.

(IV) Attention during Ventilation Operation
During the crucial stages of ventilation and air-stopping, keep fingers away from the friction pads to prevent injury from accidental pinching.

(V) Safety of Internal Structure
The internal springs of the clutch are not to be tampered with. Unauthorized disassembly poses a risk of injury and should only be conducted by qualified professionals.
