(I) Application Fields
Our product finds versatile applications across industries such as forging, printing, textile, welding, and shipbuilding. It garners acclaim, particularly in sectors like metal processing, paper machinery, woodworking machinery, and fiber machinery.

II. Product Advantages
(I) Compact Structure
- Minimal Axial Size and Lightweight: With a diminutive axial size and reduced weight, boasting low inherent rotational inertia, this enhances equipment's overall efficiency by diminishing volume and weight while maintaining uncompromised performance.
(II) Safe and Reliable
- Asbestos-free Friction Material: Featuring friction material devoid of asbestos, this ensures user safety by preventing potential health risks while adhering to modern environmental standards, delivering a safer, more reliable experience.
(III) Easy Maintenance
- Effortless Friction Pad Replacement: Simplified friction pad replacement process eliminates the need for clutch disassembly, significantly cutting maintenance costs and time, thus boosting maintenance efficiency and minimizing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Innovative Disc Arc Design: This unique design optimizes heat dissipation, effectively lowering operational temperatures, prolonging product lifespan, and ensuring stability even during extended high-load operations.
(V) Quick Response
- Rapid Clutching and Braking: Engineered for swift response, this feature allows for quick clutching and braking, satisfying the demand for fast-paced machinery operations, thereby enhancing production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Equipped with an array of connection methods, this product offers flexibility to adapt to varying site requirements, ensuring seamless integration with various equipment.


III. Product Structure
The pneumatic clutch brake is composed of the following critical components:
- Clutch Body: Mounted on the main shaft of the equipment, with a customizable center hole size per customer requirements (size range as per sample); this core component is vital to the clutch's function.
- Clutch Ear Plate and Brake Ear Plate: Ingeniously interconnected to the flywheel and machine body via four precision-engineered pins, ensuring unwavering stability and flawless operation of the clutch and brake systems.
- Friction Pads (Blocks): The heart of the clutching and braking mechanism, these pads masterfully manage the seamless flow and interruption of power, ensuring efficiency and reliability.
- Clutch Pins, Brake Pins, and Locking Plates: These components are meticulously crafted for steadfast connection and fixation. Locking plates are expertly embedded within pin grooves and securely affixed to the flywheel or machine body, effectively preventing any axial pin movement.


IV. Working Principle
(I) Clutching Process
When external compressed air surges into the clutch cylinder through the intake hole, it propels the piston into action. The dynamic interplay between friction pads, the clutch body, and the flat key facilitates the rotation of the driven part, beautifully actualizing clutch engagement and power transmission.

(II) Braking Process
Upon cessation of air supply, the spring-driven piston reverses its motion. This reverse action, coupled with the friction pads, clutch body, and flat key, ensures the driven part halts almost instantaneously. With a braking time as swift as 0.01 - 0.02 seconds, the system guarantees rapid stoppage.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
To achieve precise installation accuracy and stability, the hole tolerance for the four pins must adhere to H7 standards, and the hole center must align parallelly with the main shaft center.

(II) Geometric Tolerance and Roughness Requirements
Strict adherence to national standards is paramount for the geometric tolerance and roughness of the center hole and keyway. The customer's main shaft must also comply with these stringent standards to enhance product performance.

(III) Installation Sequence Suggestions
Customers are encouraged to adapt the installation sequence to suit specific scenarios. Generally, commence with the installation of clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body for optimal results.

(IV) Installation Notes for Square Pins
Square pins are essential in compensating for installation size discrepancies between two pins and mitigating thermal deformation due to clutch heating. It is crucial that the two flat surfaces of the square pin maintain parallel alignment with the radial direction of the ear plate.

(V) Sealing Requirements for Axial Air Intake
For axial air intake scenarios, it is vital to affix sealing caps at both ends of the clutch to effectively prevent any gas leakage, ensuring system integrity.

(VI) Check after Installation
Post-installation, ensure that both the clutch end and brake end operate with fluidity, as this is critical for the seamless functionality of the clutch and brake systems.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
At Shandong Tenord Machinery Equipment Co., Ltd., every clutch we sell is meticulously inspected to ensure top-notch quality. Customers are advised against unauthorized disassembly, as it might result in damages for which we cannot be held accountable. Should you encounter any quality issues, please contact us promptly, and we will resolve them swiftly.

(II) Friction Pad Replacement Method
Friction pads are essential yet expendable components of our machines. Over time, through regular usage, these pads experience significant wear and need replacement. Our designs make this process straightforward, eliminating the need to disassemble ear plates or the clutch. Here's how you can do it:
- Replacement without Air Supply: Start by loosening the clutch ear plate, then proceed to remove the bolts and nuts securing the worn friction pads. Swap them with brand-new ones and securely tighten the bolts and nuts.
- Replacement with Air Supply: Similar to the previous method, loosen the brake ear plate and follow the identical steps to replace the friction pads.

(III) Timing for Friction Pad Replacement
- For equipment like presses, if achieving the rated capacity becomes a challenge, inspect the friction pads to determine if replacement is necessary.
- Once the friction pads' wear surpasses 50% of their original thickness, it is advisable to replace them promptly to ensure optimal performance and safety.

VII. Product Selection
Selecting the right clutch is vital for the efficacy and longevity of your equipment. It significantly influences performance and safety.
- Consequences of Improper Selection: An undersized clutch won't meet operational demands; an oversized one not only inflates costs but could also lead to overheating, accelerated friction pad wear, and premature sealing ring aging.
- Selection Suggestions: Rely on our comprehensive product samples or consult with our knowledgeable technicians. We are committed to offering expert advice tailored to your specific needs.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
Avoid direct contact with the clutch during high-speed operation to prevent accidents. Safety is our priority.

(II) Protection from High Temperature
Refrain from touching the clutch immediately after operation to prevent burns. Allow approximately 30 minutes for the clutch to cool down to a safe temperature before commencing any maintenance activities.

(III) Side Protection
Standing near the clutch at any point of operation is hazardous due to potential projectile risks. Ensure a protective cover is utilized for safe usage.

(IV) Attention during Ventilation Operation
During ventilation processes, avoid contact with the friction pads to prevent injury.

(V) Safety of Internal Structure
Our clutches contain internal springs and should only be handled by professionals. Unauthorized disassembly can lead to serious injuries.
