(I) Application Fields
This product has gained wide acclaim in industries such as forging, printing, textile, welding, and shipbuilding. It is particularly lauded in areas like metal processing, paper processing machinery, woodworking machinery, and fiber machinery.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Light Weight: With its minimal axial size and lightweight design, it boasts low inherent rotational inertia. This efficiently reduces both the volume and weight of equipment while ensuring performance, ultimately enhancing operational efficiency.
(II) Safe and Reliable
- Asbestos-free Friction Material: The use of asbestos-free friction materials eliminates any potential health risks, aligning with modern environmental and safety standards to deliver a safer, more reliable user experience.
(III) Easy Maintenance
- Simple Friction Pad Replacement: Maintenance is a breeze with friction pad replacements that don't require disassembling the clutch. This significantly cuts maintenance costs and time, boosting maintenance efficiency and minimizing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: Ingeniously crafted with a unique disc arc design, it enhances heat dissipation, thus reducing operational temperatures. This prolongs the product's lifespan and maintains equipment stability during prolonged, high-load operations.
(V) Quick Response
- Fast Clutching and Braking: Offering rapid response capabilities, it efficiently performs clutching and braking functions. This meets the demand for quick response in various mechanical applications, driving up production efficiency.
(VI) Diverse Connection Methods
- Flexible Connection Options: With a variety of connection methods, it's designed to adapt flexibly to diverse site requirements, seamlessly integrating with various equipment for optimal performance.


III. Product Structure
The pneumatic clutch brake is composed of several essential components:
- Clutch Body: Positioned on the main shaft of the equipment, the center hole size can be tailored according to specific customer needs (refer to the sample for size range). It is the pivotal component of the clutch.
- Clutch Ear Plate and Brake Ear Plate: Ingeniously linked to the flywheel and machine body of the equipment via four robust pins, these components ensure the seamless and stable functioning of both the clutch and brake.
- Friction Pads (Blocks): These indispensable elements play a pivotal role in the clutching and braking mechanism, effectively facilitating the transmission and interruption of power with precision.
- Clutch Pins, Brake Pins, and Locking Plates: Essential for the connection and secure fixing of various components, these parts include locking plates that are precisely embedded in pin grooves and firmly affixed to the flywheel or machine body with screws, thereby preventing any axial movement of the pins.


IV. Working Principle
(I) Clutching Process
External compressed air is skillfully channeled into the clutch cylinder through the intake hole, prompting the piston to move. This action, through the friction pads, clutch body, and flat key, results in the rotation of the driven part, thereby achieving clutch engagement and enabling seamless power transmission.

(II) Braking Process
Upon cessation of the air supply, the piston is driven in the reverse direction by the spring's force, and through the friction pads, clutch body, and flat key, the driven part is swiftly braked. The braking process is remarkably quick, taking only 0.01 - 0.02 seconds, ensuring the equipment can halt almost instantaneously.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
The installation precision for the four pins demands a hole tolerance of H7, with the hole center meticulously aligned parallel to the main shaft center, guaranteeing the installation's accuracy and the pins' stability.

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

(III) Installation Sequence Suggestions
Customers have the flexibility to choose the installation sequence based on specific scenarios. Typically, it's recommended to first install the clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body.

(IV) Installation Notes for Square Pins
Square pins serve to correct installation size discrepancies between two pins and counteract plate thermal deformation due to clutch heating. Ensure that the two flat surfaces of the square pin are parallel to the ear plate's radial direction for optimal performance.

(V) Sealing Requirements for Axial Air Intake
For axial air intake systems, it is crucial to install sealing caps at both ends of the clutch to effectively prevent any potential gas leakage.

(VI) Check after Installation
Post-installation, ensure that both the clutch and brake ends are capable of moving freely to confirm the clutch and brake's faultless operation.

Product Description

VI. Product Maintenance
(I) Expert Maintenance Recommendations
Each clutch provided by Shandong Tenord Machinery Equipment Co., Ltd. is rigorously tested and approved before sale. Customers must refrain from unauthorized disassembly of the clutch, as we will not be liable for any damages caused by such actions. Should any quality issues arise, promptly notify us, and we will address them swiftly.

(II) Efficient Friction Pad Replacement Technique
Friction pads are consumable and require replacement after extended use when they exhibit significant wear. Our friction pad replacement method is straightforward, eliminating the need to disassemble the ear plates or clutch. Follow these simple steps:
- Replacement without Air Supply: Begin by loosening the clutch ear plate, then remove the bolts and nuts securing the friction pads. Proceed by replacing them with new pads, and securely tighten the bolts and nuts.
- Replacement with Air Supply: Start by loosening the brake ear plate and follow the same procedure to install new friction pads.

(III) Optimal Timing for Friction Pad Replacement
- For machinery such as presses, inspect the friction pads if the equipment fails to achieve its rated capacity.
- Replace friction pads promptly when their wear exceeds half the thickness of new ones.

VII. Product Selection
Choosing the right clutch is vital as it directly affects the performance of your equipment.
- Consequences of Incorrect Selection: A clutch too small won't meet capacity demands and one too large increases costs and risks overheating, leading to accelerated wear and seal ring aging.
- Selection Tips: Customers are encouraged to refer to our company's samples or consult our technical team for expert advice, ensuring the best selection for your needs.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
Never touch the clutch, with hands or objects, while it is in high-speed rotation to prevent accidents.

(II) High-Temperature Safety Measures
Avoid direct contact with the clutch immediately after it stops to prevent burns. Permit a cool-down period of approximately 30 minutes before conducting any maintenance.

(III) Lateral Safety Measures
Standing beside the rotating clutch is strictly prohibited to prevent injury from flying debris. Always ensure a protective cover is in place during operation.

(IV) Caution during Ventilation Operations
During ventilation and air-stopping processes, avoid contact with the friction pads to prevent finger injuries.

(V) Internal Structure Safety
The clutch contains internal springs. Unauthorized disassembly is dangerous and should only be performed by trained professionals to avoid harm.
