(I) Application Fields
Our product finds extensive usage in diverse industries, including forging, printing, textile, welding, and shipbuilding. It is highly acclaimed, particularly in metal processing, paper processing machinery, woodworking, and fiber machinery sectors.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Light Weight: With a minimal axial size and lightweight design, the inherent rotational inertia is significantly reduced. This effectively minimizes the equipment's overall volume and weight while optimizing performance, greatly enhancing operational efficiency.
(II) Safe and Reliable
- Asbestos-Free Friction Material: Our product features friction materials devoid of asbestos, thus eliminating any health hazards associated with asbestos while conforming to modern environmental and safety standards, ensuring a safer, more reliable user experience.
(III) Easy Maintenance
- Effortless Friction Pad Replacement: Friction pad replacement is straightforward, requiring no clutch disassembly. This substantially lowers maintenance costs and time, boosting maintenance efficiency and minimizing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Innovative Disc Arc Design: Our unique disc arc design dramatically enhances the product's heat dissipation capabilities, effectively reducing operational temperatures. This prolongs product lifespan and ensures equipment stability during prolonged high-load operations.
(V) Quick Response
- Rapid Clutching and Braking: With an impressively fast response time, the product swiftly executes clutching and braking functions, meeting the rapid response requirements of various mechanical equipment, thereby boosting production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Equipped with multiple flexible connection methods, it offers strong adaptability to different site requirements, ensuring perfect compatibility with a wide range of equipment.


III. Product Structure
The pneumatic clutch brake comprises key components such as:
- Clutch Body: Strategically mounted on the equipment's main shaft, with a customizable center hole size as per customer requirements (refer to sample for size range). It serves as the clutch's core component, ensuring optimal functionality.
- Clutch Ear Plate and Brake Ear Plate: Meticulously engineered to perfection, these plates are seamlessly connected to the flywheel and machine body with four robust pins. This ensures unparalleled stability and reliability in the clutch and brake's operation, optimizing performance on every use.
- Friction Pads (Blocks): Serving as the heart of the clutch and brake system, these friction pads are vital in orchestrating the seamless clutching and braking processes. They adeptly manage the transmission and interruption of power, ensuring smooth and efficient machinery operation.
- Clutch Pins, Brake Pins and Locking Plates: Essential for the secure connection and fixation of various components, these pins and plates are crafted for precision. The locking plates, ingeniously embedded in pin grooves, are securely fastened to the flywheel or machine body with screws, effectively preventing any axial displacement of the pins for dependable operation.


IV. Working Principle
(I) Clutching Process
In this process, external compressed air is channeled into the clutch cylinder through the intake hole, propelling the piston into motion. This action, through the cooperation of friction pads, clutch body, and flat key, rotates the driven part, facilitating seamless clutch engagement and flawless power transmission.

(II) Braking Process
Upon cessation of air supply, the spring propels the piston in reverse, swiftly engaging the friction pads, clutch body, and flat key to brake the driven part. This rapid braking process, taking merely 0.01 - 0.02 seconds, guarantees prompt and efficient halting of the equipment for superior safety and control.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
To ensure optimal installation precision and stability, the pin installation holes must have a tolerance of H7, with the hole center perfectly parallel to the main shaft center. This meticulous alignment is crucial for maintaining the robust performance of the pins.

(II) Geometric Tolerance and Roughness Requirements
Strict adherence to national standards for geometric tolerance and roughness of the center hole and keyway is imperative. Similarly, ensuring the main shaft's geometric tolerance and roughness meet specified standards elevates product performance to new heights.

(III) Installation Sequence Suggestions
Flexibility is key when it comes to installation. Customers can adapt the sequence based on specific scenarios, though generally, it's advisable to begin with the installation of the clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body, to ensure a smooth setup.

(IV) Installation Notes for Square Pins
Square pins are ingeniously designed to rectify any installation size discrepancies between two pins and counteract the thermal deformation of plates due to clutch heating. Ensure that the two flat surfaces of the square pin align 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's crucial to install sealing caps at both clutch ends to effectively prevent gas leakage and maintain system integrity.

(VI) Check after Installation
A thorough post-installation check is essential. Ensure that both the clutch end and the brake end move effortlessly to confirm the clutch and brake are operating at peak efficiency and reliability.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every clutch we offer at Shandong Tenord Machinery Equipment Co., Ltd. is rigorously tested and approved. Customers should refrain from unauthorized disassembly, as this can lead to damage for which we cannot take responsibility. Should you encounter any quality issues, promptly inform us, and we will address your concerns swiftly and efficiently.

(II) Friction Pad Replacement Method
Friction pads are essential yet expendable components of our products. They should be replaced after extensive use when wear becomes significant. Our design facilitates easy replacement without needing to disassemble ear plates or the clutch itself. Here's how:
- Replacement without Air Supply: Simply loosen the clutch ear plate, remove the bolts and nuts securing the friction pads, replace them with new ones, and then re-tighten the bolts and nuts.
- Replacement with Air Supply: Loosen the brake ear plate and proceed with the friction pad replacement following the same steps as above.

(III) Timing for Friction Pad Replacement
- For machines like presses, if they can't achieve their rated capacity, inspect the friction pads for possible replacement needs.
- When friction pad wear exceeds 50% of their original thickness, it's time to replace them to maintain optimal performance.

VII. Product Selection
Selecting the right clutch is paramount to the effectiveness of your equipment. Choose wisely!
- Consequences of Improper Selection: A clutch that is too small won't meet capacity needs, while an oversized one can inflate costs and potentially cause overheating, leading to accelerated wear of friction pads and quicker aging of sealing rings.
- Selection Suggestions: Choose from our comprehensive samples or consult our skilled technicians for expert advice to ensure the ideal selection for your needs.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
To prevent accidents, never touch the clutch or insert objects while it is spinning at high speeds.

(II) Protection from High Temperature
Avoid direct contact with the clutch immediately after operation to prevent burns. Allow a cooling period of approximately thirty minutes post-operation before undertaking any maintenance.

(III) Side Protection
Always avoid standing to the side of a rotating clutch to prevent accidents from potential debris. Ensure a protective cover is fitted during operation.

(IV) Attention during Ventilation Operation
During ventilation cycles, keep fingers away from the friction pads to avoid injury.

(V) Safety of Internal Structure
Internal springs are integral to the clutch mechanism. Unauthorized disassembly is prohibited to prevent injury. Should disassembly be necessary, it must be performed by qualified individuals only.
