(I) Application Fields
This versatile product finds extensive application in diverse sectors such as forging, printing, textiles, welding, and shipbuilding. It has garnered exceptional acclaim in areas including metal processing, paper processing machinery, woodworking machinery, and fiber machinery.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Light Weight: Its minimal axial size and lightweight design, coupled with low inherent rotational inertia, significantly reduce the equipment's overall volume and mass while upholding high performance, thereby boosting the equipment's operational efficiency.
(II) Safe and Reliable
- Asbestos-free Friction Material: The friction material is entirely devoid of asbestos, eliminating any health risks associated with asbestos and meeting modern environmental and safety standards, providing users with a secure and trustworthy experience.
(III) Easy Maintenance
- Simple Friction Pad Replacement: The friction pads can be effortlessly replaced without disassembling the clutch, greatly reducing maintenance costs and time, enhancing equipment maintenance efficiency, and minimizing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: This innovative disc arc design significantly boosts the product's heat dissipation capacity, effectively lowering operational temperatures, extending product lifespan, and ensuring the equipment's stability during prolonged high-load operations.
(V) Quick Response
- Fast Clutching and Braking: It features rapid response speeds, quickly executing clutching and braking functions to meet the quick response requirements of various mechanical equipment, thereby enhancing production efficiency.
(VI) Diverse Connection Methods
- Flexible Connection Options: The product offers a variety of connection methods, allowing for flexible selection based on specific site requirements, exhibiting strong adaptability, and seamlessly matching with diverse equipment.


III. Product Structure
The pneumatic clutch brake is primarily composed of the following key components:
- Clutch Body: Mounted on the equipment's main shaft, with a customizable center hole size per 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 through four robust pins, these components ensure the flawless and stable operation of the clutch and brake, optimizing performance at every turn.
- Friction Pads (Blocks): Integral to the clutching and braking process, these friction pads seamlessly facilitate the smooth transmission and interruption of power, guaranteeing efficient performance.
- Clutch Pins, Brake Pins, and Locking Plates: These essential components are crucial for securely connecting and fixing various parts. Particularly, the locking plates are intricately embedded in the pin grooves and firmly fixed on the flywheel or machine body with precision screws, preventing any unwanted axial movement of the pins.


IV. Working Principle
(I) Clutching Process
As external compressed air gracefully enters the clutch cylinder through the intake hole, it pushes the piston into motion. The synergy of friction pads, clutch body, and flat key works in harmony to rotate the driven part, achieving flawless clutch engagement and seamless power transmission.

(II) Braking Process
Upon halting the air supply, the piston is directed to move in the opposite direction by the force of the spring. This action, in conjunction with the friction pads, clutch body, and flat key, allows the driven part to be swiftly braked. The remarkable braking time, mere 0.01 - 0.02 seconds, guarantees quick stopping power, ensuring the equipment halts promptly and precisely.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
The hole tolerance for the installation of the four pins should be precisely H7. Additionally, the hole center must be perfectly parallel to the main shaft center to secure the installation accuracy and maintain the stability of the pins, enhancing overall performance.

(II) Geometric Tolerance and Roughness Requirements
The geometric tolerance and surface roughness of the center hole and keyway are meticulously crafted to meet stringent national standards. Similarly, the geometric tolerance and roughness of the customer's main shaft should align with these standards, elevating product performance to its peak.

(III) Installation Sequence Suggestions
Customers have the flexibility to adapt the installation sequence based on specific scenarios. Typically, it is recommended to first install the clutch and brake ear plates, pins, and locking plates, followed by the installation of the clutch brake body, ensuring a seamless and efficient process.

(IV) Installation Notes for Square Pins
Square pins are expertly designed to mitigate installation size errors of two pins and counteract plate thermal deformation arising from clutch heating. It's imperative to ensure that the two flat surfaces of the square pin remain parallel to the radial direction of the ear plate, securing precision installation.

(V) Sealing Requirements for Axial Air Intake
For axial air intake configurations, it's crucial to install sealing caps at both ends of the clutch. This measure effectively prevents any possible gas leakage, ensuring the integrity and reliability of the system.

(VI) Check after Installation
Post-installation, it is essential to guarantee that both the clutch end and brake end operate with complete freedom. This ensures the seamless functionality and reliable performance of the clutch and brake system.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each clutch offered by Shandong Tenord Machinery Equipment Co., Ltd. undergoes rigorous quality acceptance tests. Customers must refrain from unauthorized disassembly. Any damage arising from such actions will void our liability. Should you discover any quality issues, promptly notify us, and we will address them swiftly for your satisfaction.

(II) Friction Pad Replacement Method
Friction pads are expendable elements that require replacement after extended machine use when excessively worn. Our company's replacement process is designed for ease, eliminating the need to disassemble ear plates and the clutch. Detailed methods are as follows:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Remove the bolts and nuts securing the friction pads, insert fresh friction pads, and secure them by tightening the bolts and nuts.
- Replacement with Air Supply: Loosen the brake ear plate and follow the previously outlined steps to replace with new friction pads efficiently.

(III) Timing for Friction Pad Replacement
- For equipment such as presses, inspect the friction pads if the machine fails to achieve its rated capacity.
- Replace friction pads promptly once wear exceeds fifty percent of their original thickness to maintain optimal performance.

VII. Product Selection
Selecting the right clutch as a vital component of your equipment is essential for efficiency and longevity.
- Consequences of Improper Selection: An undersized clutch may underperform, whereas an oversized one not only inflates costs but may also lead to overheating, accelerated friction pad wear, and seal ring degradation.
- Selection Suggestions: Refer to our company's samples or consult our expert technicians for personalized guidance. We are committed to providing you with professional selection advice tailored to your needs.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
To prevent hazardous situations, avoid any contact with the clutch during high-speed rotation.

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

(III) Side Protection
Standing beside a rotating clutch is strictly prohibited to prevent accidents from flying debris. Always ensure a protective cover is in place during operation.

(IV) Attention during Ventilation Operation
During ventilation or air-stopping procedures, prevent finger contact with the friction pads to avoid injury.

(V) Safety of Internal Structure
This clutch system features internal springs. Unauthorized disassembly is dangerous and must be avoided. Any necessary disassembly should only be performed by qualified professionals.
