(I) Application Fields
Our product finds extensive applications across diverse industries such as forging, printing, textiles, welding, and shipbuilding. It is especially acclaimed in sectors like metal processing, paper, woodworking, and fiber machinery.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Light Weight: The design ensures a minimal axial profile and lightweight structure, with low rotational inertia, effectively reducing equipment volume and weight. This design boosts operational efficiency without compromising performance.
(II) Safe and Reliable
- Asbestos-free Friction Material: Using non-asbestos friction material, this product eliminates health risks associated with asbestos, aligning with modern environmental and safety standards. It delivers a safer and more dependable user experience.
(III) Easy Maintenance
- Hassle-Free Friction Pad Replacement: Friction pad swaps are straightforward, requiring no clutch disassembly, which drastically cuts down maintenance expenses and time, enhancing maintenance efficiency and minimizing downtime.
(IV) Excellent Heat Dissipation Performance
- Innovative Disc Arc Design: The unique disc arc configuration significantly augments heat dissipation, effectively lowering operational temperatures. This extends the product's lifespan and guarantees equipment stability during prolonged, high-load operations.
(V) Quick Response
- Rapid Clutching and Braking: With swift response capabilities, the product executes clutching and braking operations rapidly, fulfilling various mechanical equipment's prompt response needs and elevating production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Featuring multiple connection methods, it adapts flexibly to different site demands, showcasing strong adaptability and providing perfect compatibility with a wide range of equipment.


III. Product Structure
The pneumatic clutch brake comprises key components, including:
- Clutch Body: Mounted on the main shaft, its center hole size is customizable to client specifications (refer to sample for size range). It serves as the clutch's pivotal component.
- Clutch Ear Plate and Brake Ear Plate: Securely linked to the flywheel and body of the machinery using four precision pins, these components ensure the seamless and reliable function of the clutch and brake, maintaining operational excellence.
- Friction Pads (Blocks): These essential components are vital in the seamless clutching and braking processes, expertly facilitating the transfer and cessation of power with precision and efficiency.
- Clutch Pins, Brake Pins and Locking Plates: These are crucial for the secure connection and stability of various components. The locking plates are expertly embedded within pin grooves and firmly secured to the flywheel or machinery body with screws, effectively preventing any undesired axial movement of the pins.


IV. Working Principle
(I) Clutching Process
External compressed air is ingeniously channeled into the clutch cylinder through the intake hole, propelling the piston. The resulting interaction with friction pads, clutch body, and flat key initiates the rotation of the driven part, achieving effective clutch engagement and power transmission.

(II) Braking Process
Upon cessation of air supply, the piston swiftly reverses under spring action. Through the adept use of friction pads, clutch body, and flat key, the driven part is promptly and efficiently braked within an impressive 0.01 - 0.02 seconds, ensuring rapid equipment halt as needed.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
To guarantee precision and reliability, the tolerance of pin installation holes should adhere to an H7 standard, with the hole centers maintaining a parallel alignment to the main shaft to ensure utmost installation accuracy and stability.

(II) Geometric Tolerance and Roughness Requirements
The geometric tolerance and surface roughness of both the center hole and keyway must align strictly with national standards. Additionally, the customer's main shaft must meet corresponding criteria to optimize and elevate product performance to the highest level.

(III) Installation Sequence Suggestions
Depending on specific situations, customers have the flexibility to choose their preferred installation sequence. Generally, it is advisable to start 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 designed to counteract any installation size errors between two pins and address the thermal deformation of plates due to clutch heating. It is crucial that the two flat surfaces of each square pin are aligned parallel to the radial direction of the ear plate for proper functionality.

(V) Sealing Requirements for Axial Air Intake
For axial air intake configurations, it is essential to install sealing caps at both ends of the clutch to effectively prevent any potential gas leakage, ensuring the system's integrity and seamless operation.

(VI) Check after Installation
Following installation, it is vital that both the clutch end and brake end are able to move freely and unencumbered, confirming the smooth and reliable operation of the clutch and brake systems.

VI. Product Maintenance
(I) Expert Maintenance Insights
Every clutch that departs from Shandong Tenord Machinery Equipment Co., Ltd. reflects our unwavering commitment to quality, having passed stringent inspections. We kindly advise against self-disassembly of the clutch, as it may lead to irreversible damage, which is beyond our scope of responsibility. Encounter a quality issue? Notify us promptly, and our dedicated team will address it swiftly.

(II) Friction Pad Replacement Method
The friction pads, an inevitable consumable, require replacement after extensive usage when wear is evident. Our ingeniously designed system allows for effortless replacement of these pads without disassembling the ear plates and clutch. Here's how you can maintain efficiency with simplicity:
- Replacement without Air Supply: Gently loosen the clutch ear plate. Proceed by removing the securing bolts and nuts of the friction pads, replace them with pristine new pads, and re-tighten the bolts and nuts, restoring the system's peak performance.
- Replacement with Air Supply: Start by loosening the brake ear plate, then meticulously follow the previous steps to ensure a seamless transition to new friction pads.

(III) Timing for Friction Pad Replacement
- In high-demand equipment like presses, if the machinery struggles to achieve its rated capacity, inspect the friction pads immediately for wear and replace if necessary to ensure uninterrupted efficiency.
- When friction pad wear exceeds fifty percent of their initial thickness, it's imperative for customers to replace them promptly, safeguarding the machinery's longevity.

VII. Product Selection
Choosing the ideal clutch for your equipment is a pivotal decision, directly influencing performance and operational excellence.
- Consequences of Improper Selection: A clutch too small fails to deliver the required capacity, while an oversized clutch escalates equipment costs and risks overheating, hastening friction pad wear and seal ring degradation.
- Selection Suggestions: Rely on our comprehensive samples or consult with our expert technicians. We are committed to providing tailored advice, ensuring your choice aligns perfectly with your machinery's needs.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
To ensure absolute safety, never touch the clutch or allow objects to come in contact during high-speed rotation. This precaution is crucial to prevent potential hazards.

(II) Protection from High Temperature
Post-operation, resist the urge to touch the clutch immediately. Allow a cooling period of approximately thirty minutes to prevent burns, ensuring safe handling and maintenance.

(III) Side Protection
For optimum safety, avoid positioning yourself at the side of a rotating clutch to prevent injuries from any unexpected projectile. A robust protective cover is essential during operation.

(IV) Attention during Ventilation Operation
During both the ventilation and air-stopping phases, exercise utmost caution. Refrain from touching the friction pads with fingers to avoid potential injury.

(V) Safety of Internal Structure
The clutch's internal springs are critical to its function; hence, unauthorized disassembly is strongly discouraged to prevent injury. Should disassembly be necessary, it is paramount to entrust the task to seasoned professionals.
