(III) Easy Maintenance
- Simple Friction Pad Replacement: Designed for effortless friction pad swaps without clutch disassembly, this feature significantly cuts down on maintenance time and costs, boosting equipment uptime and maintenance efficiency.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: The innovative disc arc design amplifies heat dissipation, maintaining lower operational temperatures, prolonging lifespan, and ensuring equipment stability during extended high-load operations.
(V) Quick Response
- Fast Clutching and Braking: Engineered for rapid response, enabling swift clutching and braking, meeting the quick response demands of various mechanical equipment, thereby enhancing production efficiency.
(VI) Diverse Connection Methods
- Flexible Connection Options: Offers a variety of connection methods, providing versatile adaptability to meet distinct site requirements and ensuring compatibility with a wide array of equipment.


III. Product Structure
The pneumatic clutch brake is composed of key components including:
- Clutch Body: Centrally installed on the equipment's main shaft, with customizable center hole sizes to meet specific customer requirements (refer to the sample for size range), serving as the clutch's core component.
- Clutch Ear Plate and Brake Ear Plate: Ingeniously connected to the flywheel and machine body using four robust pins, these components are pivotal in ensuring the smooth and reliable operation of both the clutch and brake.
- Friction Pads (Blocks): These essential components are fundamental to the clutching and braking processes, ensuring seamless power transmission and interruption with unmatched efficiency.
- Clutch Pins, Brake Pins, and Locking Plates: Engineered for excellence, these elements connect and secure various parts. The locking plates are skillfully embedded in pin grooves, meticulously fixed on the flywheel or machine body with screws to prevent any axial pin movement.


IV. Working Principle
(I) Clutching Process
External compressed air is meticulously channeled into the clutch cylinder through a dedicated intake hole, initiating the piston movement. This drives the connected friction pads, clutch body, and flat key, causing the driven part to rotate and achieve clutch engagement, thus facilitating smooth power transmission.

(II) Braking Process
Upon halting the air supply, a spring mechanism swiftly repositions the piston in the opposite direction. The friction pads, clutch body, and flat key facilitate a rapid brake of the driven part, achieving a remarkable braking response time of just 0.01 - 0.02 seconds, ensuring swift equipment stoppage.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
For peak installation precision and stability, the holes for the four pins must have a tolerance of H7, with the hole center precisely parallel to the main shaft center.

(II) Geometric Tolerance and Roughness Requirements
To enhance product performance, the geometric tolerance and roughness of the center hole and keyway must rigorously adhere to national standards. Likewise, the customer's main shaft should meet these standards to ensure superior functionality.

(III) Installation Sequence Suggestions
Depending on particular situations, customers are encouraged to follow a generally recommended sequence: initially install the clutch and brake ear plates, pins, and locking plates, and subsequently proceed with the clutch brake body installation.

(IV) Installation Notes for Square Pins
Square pins play a critical role in counteracting the installation size discrepancies of two pins and the plate's thermal deformation due to clutch heating. Ensure the two flat surfaces of the square pin are aligned parallel to the radial direction of the ear plate for optimal results.

(V) Sealing Requirements for Axial Air Intake
In cases of axial air intake, it's essential to install sealing caps at both ends of the clutch to effectively prevent any gas leakage.

(VI) Check after Installation
Post-installation, ensure that both the clutch end and brake end operate freely, guaranteeing the efficient and reliable functionality of the clutch and brake systems.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every clutch sold by Shandong Tenord Machinery Equipment Co., Ltd. undergoes rigorous quality testing before delivery. We strongly advise against unauthorized disassembly of the clutch, as any damage resulting from such actions will not be covered by our warranty. Should you encounter any quality issues, please notify us promptly, and we will address them with the utmost urgency.

(II) Friction Pad Replacement Method
The friction pads are crucial consumable elements of the Kb500 Air Brake for Industrial Punch Presses and Spare Parts. These pads require replacement after extensive use when wear becomes significant. Thankfully, replacing the friction pads from Shandong Tenord is straightforward, eliminating the need for dismantling the ear plates and clutch. Follow these simple steps for replacement:
- Replacement without Air Supply: Begin by loosening the clutch ear plate, then remove the bolts and nuts that secure the friction pads. Replace them with new ones, ensuring to tighten the bolts and nuts securely.
- Replacement with Air Supply: Loosen the brake ear plate and follow the same steps to replace the friction pads with new ones.

(III) Timing for Friction Pad Replacement
- For industrial equipment like presses, if your machine fails to achieve its rated capacity, inspect the friction pads to determine if replacement is necessary.
- When the wear on the friction pads surpasses 50% of the original thickness, it's essential to replace them promptly to maintain optimal performance.

VII. Product Selection
Selecting the right clutch is vital for the efficient operation of your industrial equipment.
- Consequences of Improper Selection: A clutch that is undersized will fail to meet performance expectations, while an oversized clutch unnecessarily escalates costs and risks overheating. This can accelerate wear on friction pads and cause premature aging of sealing rings.
- Selection Suggestions: Customers are encouraged to refer to our comprehensive samples or consult with our technical experts who are ready to provide you with tailored selection advice.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
Never allow hands or foreign objects near the clutch during high-speed operation to prevent serious accidents.

(II) Protection from High Temperature
Avoid touching the clutch immediately after it ceases operation to prevent burns. Allow approximately 30 minutes for the clutch to cool to ambient temperature prior to maintenance.

(III) Side Protection
Standing beside the rotating clutch is strictly prohibited due to the risk of projectiles. Ensure a protective cover is secured over the clutch during use.

(IV) Attention during Ventilation Operation
Do not place fingers near the friction pads during the ventilation process to avoid pinching hazards.

(V) Safety of Internal Structure
The clutch contains internal springs, making unauthorized disassembly dangerous. Disassembly should only be performed by trained professionals to prevent injury.
