(I) Application Fields
This versatile product finds extensive application in industries like forging, printing, textiles, welding, and shipbuilding. It garners particular acclaim in sectors such as metal processing, paper machinery, woodworking, and fiber machinery.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Light Weight: With a diminutive axial size and featherweight design, it minimizes inherent rotational inertia. This effectively reduces the overall size and weight of your equipment while maintaining peak performance, thereby enhancing operational efficiency.
(II) Safe and Reliable
- Asbestos-free Friction Material: Our friction material is devoid of asbestos, eliminating potential health hazards and meeting modern safety and environmental standards. This ensures a safer, more reliable experience for users.
(III) Easy Maintenance
- Effortless Friction Pad Replacement: Replacing friction pads is a breeze, requiring no disassembly of the clutch, significantly cutting down on maintenance time and costs, boosting maintenance efficiency, and minimizing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: Our innovative disc arc design enhances heat dissipation capabilities, effectively reducing operational temperatures, prolonging product lifespan, and ensuring equipment stability even during prolonged, high-load usage.
(V) Quick Response
- Rapid Clutching and Braking: It offers swift response times, quickly executing clutching and braking functions to meet the high-speed demands of various machinery, thereby bolstering production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Outfitted with multiple connection methods, it can be tailored to suit various site-specific needs, offering robust adaptability and ensuring seamless integration with diverse equipment.


III. Product Structure
At the heart of our pneumatic clutch brake lies a sophisticated assembly of components:
- Clutch Body: Mounted on the equipment's main shaft, with a customizable center hole size per customer specifications (refer to the sample for size range), it serves as the pivotal component of the clutch.
- Clutch Ear Plate and Brake Ear Plate: Expertly connected to the flywheel and machine body of the equipment using four precision pins, these components guarantee the stable and seamless operation of both the clutch and brake mechanisms.
- Friction Pads (Blocks): These essential components are pivotal in both the clutching and braking processes, effectively managing the transmission and interruption of power with unmatched efficiency.
- Clutch Pins, Brake Pins, and Locking Plates: Crafted for precise connection and stability, these elements ensure optimal fixation of components. The locking plates, ingeniously embedded in pin grooves and secured with screws, prevent any unwanted axial movement of the pins, maintaining robust performance.


IV. Working Principle
(I) Clutching Process
Through a sophisticated mechanism, external compressed air enters the clutch cylinder via the intake hole, propelling the piston into motion. This action, through the interaction with friction pads, clutch body, and flat key, rotates the driven part, thereby achieving clutch engagement for effective power transmission.

(II) Braking Process
Once the air supply ceases, the piston is pushed in the reverse direction by the spring. This process, in conjunction with the friction pads, clutch body, and flat key, ensures the driven part is swiftly braked, taking only 0.01 - 0.02 seconds, thereby guaranteeing the equipment's rapid cessation.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
To ensure precision installation and stability, the hole tolerance for the four pins must adhere to H7 standards. Furthermore, the hole center should be in perfect parallel alignment with the main shaft center.

(II) Geometric Tolerance and Roughness Requirements
The geometric tolerance and surface roughness of both the center hole and keyway must strictly conform to national standards. Similarly, the customer's main shaft standards must match these requirements to elevate product performance to new heights.

(III) Installation Sequence Suggestions
Installation sequence can be tailored to specific scenarios. Typically, begin with the installation of the clutch and brake ear plates, along with the associated pins and locking plates, followed by the installation of the clutch brake body for optimal setup.

(IV) Installation Notes for Square Pins
Square pins are intelligently designed to counteract installation size discrepancies and thermal deformation of the plates due to clutch heating. Ensure that the two flat surfaces of the square pin are aligned parallel to the radial direction of the ear plate for superior performance.

(V) Sealing Requirements for Axial Air Intake
In the case of axial air intake, it is imperative to install sealing caps at both ends of the clutch. This step is crucial to prevent any gas leakage, ensuring the system's integrity.

(VI) Check after Installation
Post-installation, it is essential that the clutch and brake ends move freely, confirming the flawless operation of the clutch and brake systems, ready for peak performance.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every clutch sold by Shandong Tenord Machinery Equipment Co., Ltd. is meticulously inspected to ensure top-notch quality. Customers are advised not to disassemble the clutch privately as it may lead to damage for which the company cannot take responsibility. Should any quality issues arise, please promptly inform our support team, and we will address your concerns with utmost priority and efficiency.

(II) Friction Pad Replacement Method
Friction pads are integral consumables that demand timely replacement after extended use and noticeable wear. Our innovative design allows for a straightforward replacement process without the need to disassemble the ear plates and clutch. Follow these easy steps to ensure optimal performance:
- Replacement without Air Supply: Simply loosen the clutch ear plate, remove the securing bolts and nuts, switch out the worn friction pads with new ones, and tighten the fixtures securely.
- Replacement with Air Supply: Loosen the brake ear plate and perform the same steps as above to seamlessly install new friction pads.

(III) Timing for Friction Pad Replacement
- For machinery including presses, if the equipment fails to achieve its rated capacity, it might be time to inspect and possibly replace the friction pads.
- Should the wear on the friction pads exceed half of their original thickness, it is crucial for customers to promptly replace them to maintain optimum functionality.

VII. Product Selection
Selecting the right clutch is vital for maximizing the efficiency of your equipment. Making the right choice ensures the longevity and effectiveness of your operations.
- Consequences of Improper Selection: An undersized clutch undermines performance, while an oversized one unnecessarily inflates costs and risks overheating, accelerating wear on friction pads and seal degradation.
- Selection Suggestions: Navigate through our comprehensive product samples or consult with our expert technicians. Our team is committed to providing you with personalized and insightful selection guidance to optimize your machinery's performance.

VIII. Safety Precautions
(I) Protection during High-Speed Rotation
Always avoid contact with a spinning clutch to prevent potential hazards. Stay safe by maintaining a safe distance from the clutch when it is operating at high speeds.

(II) Protection from High Temperature
To prevent burns, never touch the clutch immediately after it stops rotating. Allow approximately 30 minutes for the clutch to cool down to room temperature before proceeding with any maintenance activities.

(III) Side Protection
Avoid standing beside the rotating clutch to prevent accidents from flying debris. Ensure a protective cover is in place during operation to safeguard against unforeseen incidents.

(IV) Attention during Ventilation Operation
During ventilation and air-stopping processes, refrain from touching the friction pads to prevent injury. Prioritize safety by keeping fingers clear of the clutch components.

(V) Safety of Internal Structure
The clutch incorporates internal springs, and unauthorized disassembly poses a risk of injury. Should the need for disassembly arise, enlist professional assistance to ensure safe and proper handling.
