This pioneering product finds its extensive application in diverse industries including forging, printing, textile, welding, and shipbuilding. It garners widespread acclaim, particularly in the domains of metal processing, paper processing machinery, woodworking machinery, and fiber machinery.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Light Weight: The design boasts a minimal axial size and light weight, characterized by low inherent rotational inertia. This effectively reduces the overall volume and weight of the equipment while maintaining superior performance, thereby augmenting the equipment's operational efficiency.
(II) Safe and Reliable
- Asbestos-free Friction Material: Our friction material is devoid of asbestos, eliminating potential health hazards associated with asbestos, and adhering to contemporary environmental and safety standards. This guarantees users a safer, more reliable experience.
(III) Easy Maintenance
- Simple Friction Pad Replacement: The process of replacing friction pads is straightforward and does not necessitate disassembling the clutch, significantly curtailing maintenance costs and time, enhancing equipment maintenance efficiency, and minimizing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: The distinctive disc arc design substantially enhances the heat dissipation capability of the product, effectively reducing operational temperature, prolonging the product's lifespan, and ensuring equipment stability during prolonged high-load operations.
(V) Quick Response
- Fast Clutching and Braking: Featuring a rapid response speed, it adeptly executes clutching and braking functions, catering to the demand for swift responsiveness across varied mechanical equipment, thereby boosting production efficiency.
(VI) Diverse Connection Methods
- Flexible Connection Options: Equipped with a variety of connection methods, it can be flexibly customized to meet diverse site requirements, exhibiting strong adaptability and the capability to harmoniously integrate with varied equipment.


III. Product Structure
The pneumatic clutch brake is primarily composed of the following vital components:
- Clutch Body: Mounted on the main shaft of the equipment, the center hole size can be customized to customer specifications (refer to the sample for size range), serving as the pivotal component of the clutch.
- Clutch Ear Plate and Brake Ear Plate: Skillfully attached to the flywheel and machine body of the equipment with precision through four robust pins, these components ensure the unwavering and stable operation of the clutch and brake mechanisms, providing seamless performance.
- Friction Pads (Blocks): These crucial components are at the heart of the clutching and braking process, effectively facilitating the transmission and interruption of power with remarkable efficiency.
- Clutch Pins, Brake Pins, and Locking Plates: Essential for the secure connection and stabilization of various components. The locking plates, ingeniously embedded in the pin grooves and securely affixed to the flywheel or machine body with screws, prevent any axial movement of the pins, ensuring steadfast performance.


IV. Working Principle
(I) Clutching Process
With the introduction of external compressed air into the clutch cylinder via the intake hole, the piston is propelled forward. This movement, assisted by the friction pads, clutch body, and flat key, results in the rotation of the driven part, achieving clutch engagement and seamless power transmission.

(II) Braking Process
Upon ceasing the air supply, the piston is prompted to retract by the spring's force, swiftly engaging the friction pads, clutch body, and flat key. This action leads to the rapid braking of the driven part within an impressive 0.01 - 0.02 seconds, guaranteeing the equipment's prompt and reliable halting.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
The installation of the four pins demands a hole tolerance of H7, with the hole center aligned parallel to the main shaft center, ensuring impeccable accuracy and stability in pin installation.

(II) Geometric Tolerance and Roughness Requirements
The geometric tolerance and surface roughness of both the center hole and keyway must adhere rigorously to national standards. Additionally, the customer's main shaft should meet these specified requirements, enhancing the overall product performance.

(III) Installation Sequence Suggestions
Customers possess the flexibility to determine the installation sequence according to situational needs. It is generally recommended to first install the 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 play a vital role in mitigating installation size discrepancies of two pins and accommodating thermal deformation of the plate due to clutch heating. It is crucial to ensure that the two flat surfaces of the square pin are aligned parallel to the radial direction of the ear plate.

(V) Sealing Requirements for Axial Air Intake
For axial air intake setups, it is imperative to install sealing caps at both ends of the clutch to effectively prevent any gas leakage, maintaining optimal performance and safety.

(VI) Check after Installation
Post-installation, the clutch end and brake end must be able to move freely. This ensures the efficient and normal operation of the clutch and brake, maintaining the integrity of the machine's performance.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each clutch from Shandong Tenord Machinery Equipment Co., Ltd. is meticulously scrutinized to ensure top-notch quality. Customers are kindly reminded not to attempt private disassembly, as it could lead to damage for which we cannot assume responsibility. Should you encounter any quality issues, please contact us immediately, and we will address them with the utmost urgency.

(II) Friction Pad Replacement Method
The friction pads are vital consumables and require replacement after extensive machine use when wear is evident. Our innovative design allows for seamless replacement without disassembling the ear plates or the clutch. Follow these straightforward steps:
- Replacement without Air Supply: Simply loosen the clutch ear plate, detach the bolts and nuts holding the worn pads, replace them with new ones, and securely fasten the bolts and nuts.
- Replacement with Air Supply: Detach the brake ear plate and repeat the same effortless procedure to refresh your machine with new friction pads.

(III) Timing for Friction Pad Replacement
- For operational efficiency, inspect the friction pads on equipment such as presses if the machine's performance declines below rated capacity.
- When the friction pads have worn down to half their original thickness, it's crucial to replace them promptly to ensure optimal functionality.

VII. Product Selection
Selecting the right clutch is essential for maximizing the performance of your equipment. Proper selection guarantees functionality and longevity.
- Consequences of Improper Selection: A clutch that's too small won't achieve desired capacities, while an oversized one raises costs and risks overheating, which may expedite friction pad wear and seal ring aging.
- Selection Suggestions: Choose confidently from our expertly curated selection in company samples, or consult with our seasoned technicians. We are dedicated to offering tailored, professional advice for your specific needs.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
For your safety, never attempt to touch the clutch or insert objects while it is in high-speed rotation, as this could result in severe injury.

(II) Protection from High Temperature
To prevent burns, avoid direct contact with the clutch right after it has stopped. Allow approximately half an hour for it to cool to room temperature before handling for maintenance.

(III) Side Protection
To protect against accidents involving projectiles, refrain from standing beside the rotating clutch. Ensure a protective cover is in place during operation.

(IV) Attention during Ventilation Operation
For your safety, do not touch the friction pads with your fingers during ventilation and air-stopping processes to avoid the danger of being pinched.

(V) Safety of Internal Structure
The clutch contains internal springs. It is imperative not to attempt disassembly on your own. If necessary, seek assistance from skilled professionals to avoid injury.
