(I) Application Fields
Our product is celebrated across a spectrum of industries, including forging, printing, textile, welding, and shipbuilding. It has garnered acclaim particularly in metal processing, paper machinery, woodworking, and fiber machinery sectors, where its performance truly shines.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Light Weight: The reduced axial size and minimized weight translate to low rotational inertia. This significantly cuts down the equipment's overall volume and weight while maintaining superb performance, thereby enhancing operational efficiency.
(II) Safe and Reliable
- Asbestos-Free Friction Material: With no asbestos, our friction material sidesteps any potential health risks, aligning with contemporary environmental and safety norms, and delivering a safer, more dependable user experience.
(III) Easy Maintenance
- Effortless Friction Pad Replacement: The design allows for straightforward friction pad replacements without clutch disassembly, markedly slashing both maintenance costs and time, boosting maintenance efficiency, and minimizing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: This distinctive disc arc design greatly enhances heat dissipation, effectively lowering operating temperatures, prolonging product lifespan, and ensuring stability during extended high-load operations.
(V) Quick Response
- Rapid Clutching and Braking: Its swift response time enables immediate clutching and braking actions, catering to machinery demanding quick reactions and thereby elevating production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Multiple connection methods allow for flexible adaptation to varied site requirements, ensuring compatibility with a wide array of equipment and improving overall adaptability.


III. Product Structure
The composition of the pneumatic clutch brake includes several key components:
- Clutch Body: Mounted on the equipment's main shaft, the center hole size is customizable as per client specification (refer to sample for size range), forming the core of the clutch mechanism.
- Clutch Ear Plate and Brake Ear Plate: Meticulously anchored with precision, these components connect seamlessly to the flywheel and machine body through four robust pins, guaranteeing the clutch and brake's unwavering stability during operation.
- Friction Pads (Blocks): A vital player in the clutching and braking performance, these pads facilitate smooth power transmission and interruption, ensuring peak operational efficiency.
- Clutch Pins, Brake Pins, and Locking Plates: Essential for the secure connection and stabilization of various components. The locking plates, ingeniously embedded within the pin grooves, are securely fastened to the flywheel or machine body using screws, effectively preventing any axial movement of the pins.


IV. Working Principle
(I) Clutching Process
As external compressed air gracefully enters the clutch cylinder via the intake hole, the piston is urged into motion. This movement, channeled through exceptional friction pads, the clutch body, and flat key, activates the driven part's rotation, skillfully engaging the clutch to facilitate efficient power transmission.

(II) Braking Process
Upon halting the air supply, the piston swiftly reverses direction propelled by the spring. Through the synergy of friction pads, clutch body, and flat key, the driven part is instantly braked, achieving a remarkable stopping time of merely 0.01 - 0.02 seconds, thus ensuring prompt cessation of equipment operation.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Precision is paramount; the installation hole for the four pins must adhere to an H7 tolerance, while the hole center aligns perfectly parallel to the main shaft center, assuring unmatched installation accuracy and stability.

(II) Geometric Tolerance and Roughness Requirements
Adhering to the highest standards, the geometric tolerance and roughness of the center hole and keyway must strictly comply with national benchmarks. Correspondingly, the geometric tolerance and roughness of the customer's main shaft must meet specified criteria to elevate product performance.

(III) Installation Sequence Suggestions
Flexibility is key; customers can tailor the installation sequence to their needs. Typically, initiate 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 serve to rectify any installation size variances between two pins and mitigate plate thermal deformation due to clutch heating. It's crucial that the two flat surfaces of the square pin align parallel to the radial direction of the ear plate.

(V) Sealing Requirements for Axial Air Intake
In instances of axial air intake, it's imperative to fit sealing caps at both clutch ends, effectively curbing any potential gas leakage.

(VI) Check after Installation
Post-installation, it is essential that the clutch end and brake end move without hindrance, ensuring flawless operational integrity of both the clutch and brake mechanisms.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each state-of-the-art clutch offered by Shandong Tenord Machinery Equipment Co., Ltd. undergoes rigorous quality control. Customers are advised against unauthorized disassembly. Damages resulting from such actions are not covered by our company. Should any quality concerns arise, promptly notify us, and we will address them swiftly.

(II) Friction Pad Replacement Method
Friction pads, as crucial consumables in our machinery, require timely replacement after prolonged use. Our innovative design allows for straightforward friction pad replacement without disassembling the ear plates and clutch. Follow these clear steps:
- Replacement without Air Supply: Simply loosen the clutch ear plate, remove the securing bolts and nuts, replace with pristine friction pads, and secure the bolts and nuts once again.
- Replacement with Air Supply: Loosen the brake ear plate and follow the aforementioned steps to replace with new, high-performance friction pads.

(III) Timing for Friction Pad Replacement
- For equipment such as presses, if performance falls below rated capacity, inspect and replace friction pads if necessary.
- When friction pad wear exceeds half of their original thickness, timely replacement is crucial to maintain optimal performance.

VII. Product Selection
Selecting the correct clutch is crucial for enhancing the functionality of your equipment.
- Consequences of Improper Selection: An undersized clutch cannot meet capacity needs; an oversized clutch escalates costs and may lead to overheating, accelerated friction pad wear, and sealing ring degradation.
- Selection Suggestions: Consult our comprehensive samples or reach out to our expert technicians for professional recommendations. We are here to ensure you make the most informed choice.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
For your safety, avoid touching the clutch with hands or objects during high-speed operation to prevent hazardous situations.

(II) Protection from High Temperature
Avoid direct contact with the clutch immediately after operation to prevent burns. Allow approximately 30 minutes for the clutch to cool to ambient temperature before maintenance.

(III) Side Protection
Steer clear of standing beside a rotating clutch to prevent accidents caused by debris. Always use a protective cover during operation.

(IV) Attention during Ventilation Operation
During ventilation and air-stopping procedures, refrain from touching friction pads to avoid pinching hazards.

(V) Safety of Internal Structure
Our clutches contain internal springs; do not disassemble privately to prevent injuries. Only professionals should perform necessary disassemblies.
