This product finds extensive application in sectors like forging, printing, textiles, welding, and shipbuilding. Its excellence is particularly acknowledged in areas such as metal processing, paper processing machinery, woodworking machinery, and fiber machinery.

II. Product Advantages
(I) Compact and Efficient Design
- Minimal Axial Size and Lightweight Construction: Its compact axial dimensions and lightweight build significantly reduce the equipment's overall size and weight, without compromising on performance. This enhances operational efficiency and performance of the equipment.
(II) Safety and Reliability at Its Core
- Asbestos-Free Friction Material: The friction material is devoid of asbestos, eliminating any health risks and aligning with modern environmental and safety standards, ensuring a safer and more dependable user experience.
(III) Effortless Maintenance
- Easy Friction Pad Replacement: Friction pads can be replaced effortlessly without disassembling the clutch, reducing maintenance costs and downtime significantly, thereby boosting equipment maintenance efficiency.
(IV) Superior Heat Dissipation
- Innovative Disc Arc Design: The design dramatically enhances the product's heat dissipation capability, lowering operational temperatures, extending the product's lifespan, and ensuring stable performance even during prolonged high-load operations.
(V) Lightning-Fast Response
- Rapid Clutching and Braking: With an exceptional response speed, it swiftly accomplishes clutching and braking tasks, meeting the rapid response demands of varied machinery, thereby enhancing production efficiency.
(VI) Versatile Connection Options
- Multiple Connection Methods: Equipped with a variety of connection options, it can be flexibly chosen to match different site requirements, showcasing strong adaptability and perfect compatibility with a range of equipment.


III. Product Structure
The pneumatic clutch brake comprises the following key components:
- Clutch Body: Mounted on the equipment's main shaft with customizable center hole sizes according to customer needs (size range as per sample). It stands as the clutch's core component.
- Clutch Ear Plate and Brake Ear Plate: Attached securely to the flywheel and machine body via four pins, ensuring the clutch and brake operate stably and reliably.
- Friction Pads (Blocks): These essential components serve as the heart of the clutching and braking mechanism, expertly facilitating the seamless transmission and interruption of power.
- Clutch Pins, Brake Pins and Locking Plates: Craftily designed for the secure connection and fixation of various components. The locking plates, ingeniously embedded in the pin grooves, are fastened onto the flywheel or machine body with screws to ensure the pins remain steadfastly in place, preventing any unwanted axial movement.


IV. Working Principle
(I) Clutching Process
External compressed air gracefully enters the clutch cylinder via the intake hole, setting the piston into motion. This elegant process involves friction pads, the robust clutch body, and a flat key, collectively rotating the driven part to achieve clutch engagement and empower the transmission of power seamlessly.

(II) Braking Process
Upon ceasing the air supply, the piston, urged by the resilient spring, retreats in the opposite direction. This dynamic interaction, involving friction pads, the clutch body, and a flat key, swiftly halts the driven part. The impressive braking time ranges from a mere 0.01 to 0.02 seconds, ensuring the equipment comes to a halt with remarkable speed and precision.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
For optimal installation accuracy and stability, the hole tolerance for the four pins should be at H7 standard. Ensuring parallelism between the hole center and the main shaft center is crucial in achieving precision and steadfastness of the pins.

(II) Geometric Tolerance and Roughness Requirements
Adhering to national standards, the geometric tolerance and roughness of the center hole and keyway are paramount. Likewise, the corresponding specifications for the customer's main shaft must be met to enhance the product's superior performance.

(III) Installation Sequence Suggestions
Flexibility is key—customers can choose the installation sequence based on their unique circumstances. Generally, it is advisable to first install the clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body.

(IV) Installation Notes for Square Pins
Square pins are ingeniously deployed to rectify installation size discrepancies between two pins and counteract the plate thermal deformation due to clutch heating. Ensure the two flat surfaces of the square pin remain parallel to the radial direction of the ear plate for optimal alignment.

(V) Sealing Requirements for Axial Air Intake
For axial air intakes, it is critical to install sealing caps at both ends of the clutch to effectively prevent any gas leakage, maintaining the integrity of the system.

(VI) Check after Installation
Post-installation, it is imperative that both the clutch end and brake end operate with smooth freedom of movement, ensuring the clutch and brake function effortlessly and reliably.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each clutch distributed by Shandong Tenord Machinery Equipment Co., Ltd. is rigorously tested to ensure top quality. We strongly advise against any unauthorized disassembly of the clutch, as it may void your warranty and result in damage for which we cannot be held accountable. Should you encounter any quality issues, please notify us promptly, and rest assured that we will address your concerns with the utmost urgency.

(II) Friction Pad Replacement Method
Friction pads, being consumable components of the machine, require timely replacement once they become significantly worn after prolonged use. Shandong Tenord's design allows for hassle-free replacement of these pads without the need to disassemble the ear plates and clutch. Follow the detailed procedure below:
- Replacement without Air Supply: Begin by loosening the clutch ear plate, then proceed to remove the bolts and nuts securing the friction pads. Insert the new friction pads, and ensure the bolts and nuts are firmly tightened.
- Replacement with Air Supply: Start by loosening the brake ear plate. Follow the same steps as above to install new friction pads, ensuring all components are securely fastened.

(III) Timing for Friction Pad Replacement
- For machinery like presses, if the equipment fails to achieve its rated capacity, inspect the friction pads for potential replacement.
- When the wear on the friction pads exceeds fifty percent of their original thickness, it is imperative for customers to replace them immediately to maintain optimal performance.

VII. Product Selection
Selecting the right clutch is vital for the functionality of your equipment.
- Consequences of Improper Selection: Choosing an undersized clutch will result in failure to meet the rated capacity. Conversely, selecting an oversized clutch increases equipment costs, leads to overheating, accelerates wear on friction pads, and expedites the aging of sealing rings.
- Selection Suggestions: We invite customers to refer to our comprehensive product catalog or reach out to our team of experts for personalized consultation. Our experienced technicians are ready to provide tailored recommendations to suit your specific needs.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
For your safety, never place hands or objects near the clutch when it is in high-speed rotation to prevent accidents.

(II) Protection from High Temperature
Refrain from touching the clutch immediately after it stops rotating, as it remains hot and may cause burns. Allow approximately 30 minutes for the clutch to cool to a safe temperature before initiating any maintenance work.

(III) Side Protection
To safeguard against potential hazards such as flying debris, avoid standing beside the rotating clutch. Always ensure a protective cover is in place during the operation of the clutch.

(IV) Attention during Ventilation Operation
During ventilation and air-stopping procedures, keep fingers away from the friction pads to avoid the risk of being pinched.

(V) Safety of Internal Structure
The clutch contains internal springs, and unauthorized disassembly could lead to injury. Any necessary disassembly should be performed exclusively by trained professionals.
