- Asbestos-Free Friction Material: Our friction material is devoid of asbestos, aligning with modern health, environmental, and safety standards, offering a safer, more trustworthy user experience.
(III) Easy Maintenance
- Effortless Friction Pad Replacement: Change friction pads swiftly without dismantling the clutch, significantly cutting down on maintenance costs and time, elevating maintenance efficiency, and minimizing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Innovative Disc Arc Design: This unique design significantly enhances heat dissipation, lowers operational temperatures, prolongs product lifespan, and ensures stability during prolonged high-load operations.
(V) Quick Response
- Rapid Clutch and Brake Activation: Boasting a swift response time, it efficiently executes clutching and braking, meeting the rapid response demands of diverse machinery, thereby boosting production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Equipped with various connection methods, allowing flexible selection based on site-specific requirements, ensuring perfect compatibility with a range of equipment.


III. Product Structure
The pneumatic clutch brake is ingeniously constructed of the following vital components:
- Clutch Body: Securely mounted on the equipment's main shaft, customizable center hole dimensions (refer to sample for size range), serving as the clutch's integral component.
- Clutch Ear Plate and Brake Ear Plate: Securely anchored to the flywheel and machine body via four robust pins, this setup guarantees the unwavering and smooth function of the clutch and brake, allowing for precision and reliability in every operation.
- Friction Pads (Blocks): These essential elements are pivotal in powering the clutch and braking mechanism, efficiently managing the seamless transmission and interruption of power for optimal performance.
- Clutch Pins, Brake Pins and Locking Plates: These components are vital for secure connectivity and stability, with the locking plates ingeniously embedded within pin grooves and firmly affixed to the flywheel or machine body with screws, adeptly preventing any unwanted axial movement.


IV. Working Principle
(I) Clutching Process
Through the strategic entry of external compressed air into the clutch cylinder, the piston is propelled forward. This movement, amplified by the friction pads, clutch body, and flat key, ensures that the driven part rotates, thus engaging the clutch for seamless power transmission.

(II) Braking Process
When air supply is halted, the piston reverts due to spring tension, rapidly engaging the friction pads, clutch body, and flat key. This quick action facilitates the swift braking of the driven part, achieving stoppage within an impressive 0.01 - 0.02 seconds, underscoring the equipment's rapid response capability.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Adhering to a hole tolerance of H7, the pin installation must align parallel to the main shaft center. This precision is crucial to ensuring the stability and accuracy of pin placement, directly influencing equipment reliability.

(II) Geometric Tolerance and Roughness Requirements
It is imperative that the center hole and keyway's geometric tolerance and roughness align with national standards. Likewise, the customer's main shaft must meet these stringent requirements to enhance the overall performance and longevity of the product.

(III) Installation Sequence Suggestions
While customers can adapt the installation sequence to their specific needs, it is generally advisable to begin with the installation of clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body for streamlined assembly.

(IV) Installation Notes for Square Pins
Square pins play a crucial role in mitigating installation size discrepancies and thermal deformation of plates due to clutch heating. Ensure the parallel alignment of the square pin's flat surfaces with the ear plate's radial direction for optimal functionality.

(V) Sealing Requirements for Axial Air Intake
In cases of axial air intake, the installation of sealing caps at both ends of the clutch is essential to effectively prevent any gas leakage, safeguarding the integrity and efficiency of the system.

(VI) Check after Installation
Post-installation, it is critical to verify that both the clutch and brake ends exhibit free movement, ensuring that the clutch and brake operate smoothly and as intended, maintaining peak performance standards.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every clutch from Shandong Tenord Machinery Equipment Co., Ltd. is rigorously tested for quality. Customers are advised not to dismantle the clutch unauthorizedly. Our company holds no responsibility for damages due to such actions. Should you encounter any quality issues, please contact us promptly, and we assure a swift resolution to your concerns.

(II) Friction Pad Replacement Method
Friction pads are vital yet consumable components of the High-Performance Clutch Brake Punching Machine for Knuckle Joint Presses. After prolonged use, their replacement is necessary when they show significant wear. We have simplified this process, ensuring no need to disassemble the ear plates or clutch. Follow these straightforward steps:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Remove the bolts and nuts securing the friction pads. Install new friction pads, and securely retighten the bolts and nuts.
- Replacement with Air Supply: Follow the same procedure as above. Start by loosening the brake ear plate and proceed with replacing the worn friction pads.

(III) Timing for Friction Pad Replacement
- For presses and similar machinery, monitor the equipment's capacity. If it fails to achieve rated performance, inspect the friction pads for potential replacement.
- When the friction pads exhibit wear exceeding fifty percent of their original thickness, timely replacement is recommended.

VII. Product Selection
Selecting the right clutch is integral to the efficient functioning of your equipment. Ensuring correct sizing is essential for optimal performance.
- Consequences of Improper Selection: An undersized clutch will not meet capacity requirements. Conversely, an oversized clutch leads to unnecessary cost increases, overheating, accelerated friction pad wear, and rapid sealing ring aging.
- Selection Suggestions: Refer to our comprehensive company samples or engage with our expert technicians for tailored guidance. We are committed to providing exceptional selection advice.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
Avoid direct contact with the clutch during high-speed operation to prevent injury.

(II) Protection from High Temperature
Direct contact with the clutch post-operation is prohibited due to high temperatures. Allow a cooling period of approximately thirty minutes before commencing maintenance.

(III) Side Protection
Refrain from standing beside the rotating clutch to avoid incidents from flying debris. Implement a protective cover over the clutch during its operation.

(IV) Attention during Ventilation Operation
During ventilation or air-stopping processes, keep fingers clear of the friction pads to avoid injury.

(V) Safety of Internal Structure
The clutch contains internal springs. Unauthorized disassembly poses injury risks. Only qualified professionals should undertake any necessary disassembly.
