(I) Application Fields
This versatile product finds extensive use in industries including forging, printing, textiles, welding, and shipbuilding. It has garnered acclaim, particularly in sectors like metal processing, paper processing machinery, woodworking machinery, and fiber machinery.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Light Weight: Featuring a reduced axial size and light weight, with minimal inherent rotational inertia, it significantly reduces the overall equipment volume and weight while optimizing performance, thus enhancing operational efficiency.
(II) Safe and Reliable
- Asbestos-Free Friction Material: The friction material is free of asbestos, eliminating potential health hazards and aligning with contemporary environmental and safety standards. This ensures a safer, more reliable user experience.
(III) Easy Maintenance
- Effortless Friction Pad Replacement: Friction pads can be easily replaced without clutch disassembly, substantially lowering maintenance costs and time, improving maintenance efficiency, and minimizing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Distinctive Disc Arc Design: This unique design enhances heat dissipation capabilities, effectively lowering operational temperatures, extending product lifespan, and ensuring stability during prolonged high-load operations.
(V) Quick Response
- Rapid Clutching and Braking: With a swift response speed, it facilitates quick clutching and braking, meeting the demands for rapid response in diverse machinery, thereby boosting production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Equipped with multiple connection methods, it offers flexibility to suit different site requirements, ensuring adaptability and compatibility with various equipment.


III. Product Structure
The pneumatic clutch brake is composed of these essential components:
- Clutch Body: Mounted on the equipment's main shaft, its center hole size is customizable as per client specifications (see sample for size range), serving as the pivotal element of the clutch.
- Clutch Ear Plate and Brake Ear Plate: Meticulously engineered to connect securely to the flywheel and machine body via four robust pins. This configuration guarantees the flawless, stable operation of both the clutch and brake mechanisms.
- Friction Pads (Blocks): These integral components are pivotal in the clutching and braking processes, masterfully facilitating the seamless transmission and interruption of power, ensuring smooth operation.
- Clutch Pins, Brake Pins, and Locking Plates: Essential for connecting and securing a variety of components. Ingeniously, the locking plates are embedded within pin grooves and meticulously fixed to the flywheel or machine body with precision screws, effectively preventing any axial movement of the pins.


IV. Working Principle
(I) Clutching Process
When external compressed air is introduced into the clutch cylinder through the intake valve, it drives the piston into motion. Through the adept action of friction pads, the clutch body, and an expertly fitted flat key, the driven part begins its rotation, facilitating smooth clutch engagement and ensuring uninterrupted power transmission.

(II) Braking Process
Upon cessation of air supply, the piston is reflexively driven in the opposite direction by a resilient spring. The friction pads, along with the clutch body and flat key, ensure the driven part is instantaneously braked, with an impressive braking time of just 0.01 - 0.02 seconds, guaranteeing the equipment halts promptly and safely.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Ensure the installation precision and stability of the pins by maintaining a hole tolerance of H7. Additionally, align the hole center in parallel with the main shaft center to achieve accurate and stable installation.

(II) Geometric Tolerance and Roughness Requirements
Adhere strictly to national standards for the geometric tolerance and roughness of the center hole and keyway. The customer's main shaft geometric tolerance and roughness must also conform to the requisite standards, thereby elevating product performance seamlessly.

(III) Installation Sequence Suggestions
Customers are empowered to select the installation sequence based on specific circumstances. A recommended approach is to initially install the clutch and brake ear plates, followed by the pins and locking plates, and subsequently the clutch brake body for optimal installation.

(IV) Installation Notes for Square Pins
Square pins are ingeniously utilized to counteract any installation size discrepancies between two pins and mitigate the thermal deformation of plates due to clutch heating. It's crucial to ensure the two flat surfaces of the square pin are aligned parallel to the radial direction of the ear plate for precise installation.

(V) Sealing Requirements for Axial Air Intake
For axial air intake systems, it is imperative to install sealing caps at both ends of the clutch to meticulously prevent any gas leakage, ensuring efficient operation.

(VI) Check after Installation
Post-installation, it is essential to verify that the clutch end and brake end move freely. This ensures that both clutch and brake systems operate smoothly and effectively.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each clutch distributed by Shandong Tenord Machinery Equipment Co., Ltd. undergoes stringent quality assurance procedures. It is critical for customers to refrain from unauthorized disassembly of the clutch, as this will void any responsibility from our side for damages incurred. Should any quality issues arise, immediately notify us to ensure a prompt and efficient resolution.

(II) Friction Pad Replacement Method
The friction pads are key consumable components that require substitution after extended machine usage or when significant wear is observed. Shandong Tenord Machinery Equipment Co., Ltd. has engineered a streamlined replacement system for the friction pads that eliminates the need to dismantle the ear plates and clutch. The detailed procedure is outlined as follows:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Proceed to remove the bolts and nuts securing the friction pads, replace them with new pads, and then securely retighten the bolts and nuts.
- Replacement with Air Supply: Simply loosen the brake ear plate and follow the aforementioned steps to seamlessly replace the old friction pads with new ones.

(III) Timing for Friction Pad Replacement
- For machines like presses, if the equipment fails to achieve its rated capacity, it is essential to inspect whether the friction pads require replacement.
- When the friction pads show wear exceeding 50% of their original thickness, prompt replacement is advised to maintain optimal performance.

VII. Product Selection
Choosing the right clutch is pivotal for the functionality and longevity of your machinery. An appropriately selected clutch not only enhances performance but also safeguards against premature wear.
- Consequences of Improper Selection: A clutch that is too small will fail to deliver the rated capacity, while an oversized clutch not only escalates costs but also risks overheating, accelerating friction pad wear, and hastening the aging of sealing rings.
- Selection Suggestions: Clients are encouraged to utilize our comprehensive samples or engage with our expert technicians for tailored advice to make informed selections.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
To prevent hazardous situations, it is imperative to avoid any contact with the clutch while it is in high-speed motion.

(II) Protection from High Temperature
Immediate contact with the clutch post-operation is prohibited due to risk of burns. Allow a cooling period of approximately thirty minutes after the clutch ceases operation to ensure safe handling.

(III) Side Protection
Standing adjacent to a rotating clutch is strictly forbidden to prevent injury from potential debris. Ensure a protective cover is fitted during operation for maximum safety.

(IV) Attention during Ventilation Operation
During the ventilation process, it is crucial to avoid contact with the friction pads with fingers to prevent accidental pinching.

(V) Safety of Internal Structure
The clutch's internal spring mechanisms should not be tampered with by non-professionals. Only qualified personnel should perform disassembly to avert injury.
