(II) Safe and Reliable
- Asbestos-Free Friction Material: Our commitment to health and safety is reflected in the use of asbestos-free friction materials, which eliminate the risks associated with asbestos, in compliance with modern safety and environmental standards, ensuring a secure and reliable user experience.
(III) Easy Maintenance
- Effortless Friction Pad Replacement: Changing friction pads is straightforward and can be done without disassembling the clutch, markedly reducing maintenance time and costs, thus boosting maintenance efficiency and minimizing downtime.
(IV) Excellent Heat Dissipation Performance
- Innovative Disc Arc Design: Our proprietary disc arc design significantly enhances the product's heat dissipation capabilities, effectively lowering operational temperatures, extending product longevity, and ensuring stable performance under prolonged high-load conditions.
(V) Quick Response
- Instantaneous Clutching and Braking: Engineered for rapid response, this clutch brake swiftly executes clutching and braking actions, catering to the quick-response demands of various mechanical systems, thereby amplifying production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Channels: With a multitude of connection options available, it adapts flexibly to different site requirements, demonstrating remarkable adaptability and precise compatibility with a wide range of equipment.


III. Product Structure
The pneumatic clutch brake is comprised of essential components such as:
- Clutch Body: Mounted on the equipment's main shaft, its central hole dimension can be tailored to customer specifications (refer to sample size range), making it the pivotal element of the clutch system.
- Clutch Ear Plate and Brake Ear Plate: Elegantly secured to the flywheel and machine body via four robust pins, these components ensure seamless and stable operation of both the clutch and brake, enhancing efficiency and performance.
- Friction Pads (Blocks): These critical components are pivotal in the clutching and braking process, enabling precise transmission and interruption of power with utmost reliability.
- Clutch Pins, Brake Pins and Locking Plates: Essential for the connection and fixation of various components, with locking plates strategically embedded in pin grooves and securely fastened on the flywheel or machine body with screws to prevent any axial movement of the pins, ensuring stability and accuracy.


IV. Working Principle
(I) Clutching Process
External compressed air skillfully enters the clutch cylinder through the intake hole, propelling the piston to action. This movement, channeled through friction pads, the clutch body, and flat key, rotates the driven component to achieve clutch engagement, facilitating smooth and effective power transmission.

(II) Braking Process
Upon halting the air supply, the piston reverses direction under the spring's influence, and through the friction pads, clutch body, and flat key, the driven part halts swiftly. With a braking time of just 0.01 - 0.02 seconds, the equipment stops with remarkable speed, ensuring safety and precision.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
The installation demands a hole tolerance of H7 for the four pins, with the hole center aligned parallel to the main shaft center. This precision guarantees the superior installation accuracy and stability of the pins, essential for optimal performance.

(II) Geometric Tolerance and Roughness Requirements
Adherence to national standards for geometric tolerance and roughness of the center hole and keyway is imperative. The customer's main shaft must also meet these criteria to elevate product performance and ensure seamless operation.

(III) Installation Sequence Suggestions
Customers have the flexibility to select the installation sequence according to specific scenarios. Typically, it's advisable to first install the clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body, for a streamlined process.

(IV) Installation Notes for Square Pins
Square pins are ingeniously designed to counteract installation size errors between two pins and the thermal deformation of the plates due to clutch heating. Ensure that 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
In cases of axial air intake, it is crucial to fit sealing caps at both ends of the clutch. This prevents gas leakage, safeguarding the system's integrity and maintaining efficiency.

(VI) Check after Installation
Post-installation, it is vital to verify that the clutch end and brake end move freely. This ensures the clutch and brake operate smoothly and reliably, providing peace of mind and operational excellence.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
At Shandong Tenord Machinery Equipment Co., Ltd., our commitment to quality is paramount. Each clutch brake punching machine we offer undergoes rigorous quality control checks. To maintain this quality, we strongly advise against any unauthorized disassembly of the clutch. Any damages incurred from such actions will not be covered by our warranty. Should you encounter any quality issues, please notify us immediately, and we pledge to address them promptly, ensuring your machinery continues to operate seamlessly.

(II) Friction Pad Replacement Method
Friction pads are critical consumable components of our machines. Over time, and with extensive use, these pads may experience wear and require replacement. To facilitate a smooth replacement process, our design allows for easy replacement without disassembling the ear plates or clutch. Below, we outline the straightforward replacement techniques that ensure your equipment's optimal performance:
- Replacement without Air Supply: Simply loosen the clutch ear plate, remove the bolts and nuts securing the worn friction pads, replace them with new pads, and retighten the bolts and nuts to secure the new pads in place.
- Replacement with Air Supply: Loosen the brake ear plate and follow the aforementioned steps to replace the worn friction pads with new ones, ensuring your machine remains efficient and safe.

(III) Timing for Friction Pad Replacement
- In machinery such as presses, if the equipment fails to achieve its rated capacity, it's advisable to inspect the friction pads for wear and consider timely replacement.
- If the wear on the friction pads exceeds 50% of their original thickness, customers are recommended to replace them promptly to maintain optimal machine performance and safety.

VII. Product Selection
Selecting the right clutch for your equipment is integral to its functionality and efficiency. An appropriately sized clutch ensures seamless operation and longevity.
- Consequences of Improper Selection: A clutch that's too small won't meet the machine's operational demands, while an oversized clutch can inflate costs and may lead to overheating issues, which can expedite wear and tear on friction pads and sealing rings.
- Selection Suggestions: For ensuring the perfect fit, we recommend referring to our comprehensive product samples or consulting with our expert technicians. Our team is dedicated to offering expert advice tailored to your specific needs, enhancing your equipment's performance and reliability.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
Safety is our top priority. When the clutch is operating at high speeds, ensure that hands and objects are kept clear to prevent any potential hazards.

(II) Protection from High Temperature
After the clutch ceases operation, its surface may retain significant heat. To prevent burns, avoid direct contact with the clutch immediately after it stops. It is advisable to wait approximately 30 minutes for a safe cooldown to room temperature before commencing maintenance activities.

(III) Side Protection
Standing beside an active clutch can be perilous due to the risk of debris projection. Always ensure a protective cover is in place to safeguard against accidental injuries during clutch operations.

(IV) Attention during Ventilation Operation
During air supply and cessation processes, take care to avoid contact with friction pads to prevent potential injuries such as pinching.

(V) Safety of Internal Structure
Internally, the clutch features integral springs. Unauthorized disassembly poses a risk of injury. Any necessary disassembly should be left to qualified professionals to ensure safety and integrity of the equipment.
