(I) Application Fields
This versatile product is extensively deployed across diverse industries including forging, printing, textile, welding, and shipbuilding. It garners considerable acclaim in sectors such as metal processing, paper processing machinery, woodworking machinery, and fiber machinery.

II. Product Advantages
(I) Compact Structure
- Streamlined and Lightweight Design: Featuring minimal axial size and lightweight construction, it reduces rotational inertia. This effectively minimizes the equipment's overall size and weight while enhancing performance, thereby boosting operational efficiency.
(II) Safe and Reliable
- Asbestos - Free Friction Material: Utilizing materials free from asbestos, it eliminates health risks associated with asbestos, aligning with contemporary environmental standards. This commitment provides users with a safer and more dependable experience.
(III) Easy Maintenance
- Effortless Friction Pad Replacement: Changing friction pads is straightforward and does not necessitate disassembly of the clutch. This significantly cuts down maintenance time and costs, enhancing maintenance efficiency and minimizing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Innovative Disc Arc Design: The unique disc arc configuration greatly enhances the product's heat dissipation capability. This effectively lowers operational temperatures, extends the product's lifespan, and ensures equipment stability during prolonged high-load operations.
(V) Quick Response
- Rapid Clutching and Braking: Boasting a swift response time, it swiftly executes clutching and braking functions, catering to the quick response demands of various machinery and boosting production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Featuring multiple adaptable connection methods, it can be tailored to meet specific site requirements, ensuring robust adaptability and seamless integration with diverse equipment.


III. Product Structure
The pneumatic clutch brake is composed of several key components:
- Clutch Body: Positioned on the equipment's main shaft, the center hole size is customizable as per client specifications (refer to the sample for size range). It serves as the clutch's essential core component.
- Clutch Ear Plate and Brake Ear Plate: Expertly connected to the equipment's flywheel and body using four precision pins, ensuring the seamless and reliable operation of both the clutch and brake.
- Friction Pads (Blocks): These critical components are instrumental in the clutching and braking processes, facilitating the smooth transmission and interruption of power with impeccable efficiency.
- Clutch Pins, Brake Pins, and Locking Plates: These essential connectors and fixers are meticulously designed to securely integrate various components. The locking plates, expertly embedded within the pin grooves and secured to the flywheel or machine body with screws, prevent any undesired axial pin movement.


IV. Working Principle
(I) Clutching Process
External compressed air enters the clutch cylinder via the intake hole, propelling the piston with precision. Through the interaction of friction pads, clutch body, and flat key, the driven part rotates, executing flawless clutch engagement, and ensures seamless power transmission.

(II) Braking Process
Upon halting air supply, the piston efficiently retracts under spring force, engaging the friction pads, clutch body, and flat key for a rapid brake. With a swift stopping time of merely 0.01 - 0.02 seconds, it guarantees the equipment halts with exceptional speed.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
For installing the four pins, the hole tolerance must be H7, and the hole center should align precisely parallel to the main shaft center, thus ensuring superior installation accuracy and stability of the pins.

(II) Geometric Tolerance and Roughness Requirements
The center hole and keyway's geometric tolerance and roughness must adhere strictly to national standards. Correspondingly, the customer's main shaft must meet these requirements to enhance overall product performance significantly.

(III) Installation Sequence Suggestions
Customers have the flexibility to determine the installation sequence based on specific scenarios. As a general guide, install the clutch and brake ear plates, pins, and locking plates first, followed by the clutch brake body, ensuring a seamless assembly.

(IV) Installation Notes for Square Pins
Square pins are ingeniously utilized to counteract installation size discrepancies of two pins and mitigate thermal deformation of plates due to clutch heating. Ensure the two flat surfaces of the square pin align perfectly parallel to the radial direction of the ear plate.

(V) Sealing Requirements for Axial Air Intake
For axial air intake systems, it is crucial to fit sealing caps at both ends of the clutch meticulously to prevent any gas leakage and maintain system integrity.

(VI) Check after Installation
Post-installation, it is vital to verify that both the clutch end and brake end move without impediment, ensuring the optimal and smooth functioning of the clutch and brake system.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every clutch crafted by Shandong Tenord Machinery Equipment Co., Ltd. is rigorously tested to ensure unparalleled quality. Please do not disassemble the clutch independently, as any damage resulting from unauthorized tampering is not covered by our warranty. Should you encounter any quality issues, contact us promptly for immediate resolution.

(II) Friction Pad Replacement Method
Our clutch brake punching machines are designed with user-friendly maintenance in mind. The friction pads, being wear-prone components, require replacement after extended use. Remarkably, the procedure is straightforward: no need to disassemble ear plates or the clutch itself. Follow these clear steps to replace worn pads efficiently:
- Replacement without Air Supply: Start by loosening the clutch ear plate. Proceed to remove the bolts and nuts securing the friction pads. Swap them out with pristine new pads, and firmly secure the bolts and nuts back in place.
- Replacement with Air Supply: Begin by loosening the brake ear plate and replicate the above steps to refresh your friction pads successfully.

(III) Timing for Friction Pad Replacement
- For machinery like presses where performance dips below rated capacity, inspect the friction pads for necessary replacement.
- When the wear level of friction pads surpasses 50% of their original state, timely replacement is advised to maintain optimum performance.

VII. Product Selection
Selecting the right clutch is pivotal for the optimal functioning of your equipment. Precision matters.
- Consequences of Improper Selection: A clutch that is too small fails to meet capacity demands, while an oversized one can cause overheating, hasten friction pad wear, and increase sealing ring deterioration, plus unnecessary cost.
- Selection Suggestions: Refer to our comprehensive samples or consult with our expert technicians for tailored advice, ensuring you choose the perfect clutch for your needs.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
To prevent accidents, never touch the clutch or allow objects near it while it spins at high velocity. Safety first!

(II) Protection from High Temperature
After operation, allow the clutch to cool for about 30 minutes before handling to avoid burns. It is essential to ensure it has returned to a safe, ambient temperature.

(III) Side Protection
Avoid standing near the side of a spinning clutch, as flying debris poses a risk. Ensure a protective cover is in place to safeguard against potential hazards.

(IV) Attention during Ventilation Operation
During any ventilation or air-stopping processes, refrain from touching the friction pads to prevent injury from pinching.

(V) Safety of Internal Structure
The clutch contains internal springs that require expert handling. Disassembly should only be conducted by trained professionals to avoid injury and ensure safety.
