(I) Application Fields
This versatile product finds extensive application in diverse sectors such as forging, printing, textile, welding, and shipbuilding. It is especially lauded in fields like metal processing, paper processing machinery, woodworking machinery, and fiber machinery, where it consistently earns high praise.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Light Weight: With its minimal axial size and reduced weight, alongside low inherent rotational inertia, it effectively diminishes the overall volume and weight of the equipment while retaining optimal performance. This enhancement boosts the operational efficiency of the machinery.
(II) Safe and Reliable
- Asbestos-Free Friction Material: Free from asbestos components, the friction material mitigates potential health risks associated with asbestos exposure, aligning with contemporary environmental and safety standards, and offering a safer, more reliable user experience.
(III) Easy Maintenance
- Simple Friction Pad Replacement: Easily replace friction pads without dismantling the clutch, significantly cutting down on maintenance costs and time. This feature enhances equipment upkeep efficiency and minimizes downtime.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: The innovative disc arc design considerably boosts heat dissipation capacity, minimizing operational heat buildup, prolonging product lifespan, and ensuring stable performance during extended high-load operations.
(V) Quick Response
- Fast Clutching and Braking: Designed for swift responsiveness, it swiftly executes clutching and braking functions, meeting the quick reaction demands of varied mechanical equipment and augmenting production efficiency.
(VI) Diverse Connection Methods
- Flexible Connection Options: Featuring multiple connection methods, it offers flexible selection based on diverse site requirements, showcasing strong adaptability and seamless compatibility with an array of equipment.


III. Product Structure
The pneumatic clutch brake comprises several key components:
- Clutch Body: Positioned on the main shaft of the equipment, the center hole size is customizable to meet client specifications (size options detailed in the sample). It stands as the clutch's pivotal component.
- Clutch Ear Plate and Brake Ear Plate: Meticulously connected to the flywheel and machine body of the equipment using four robust pins, ensuring the steadfast operation of the clutch and brake, thereby guaranteeing optimal performance and reliability.
- Friction Pads (Blocks): These essential components play a pivotal role in the clutching and braking processes, enabling seamless power transmission and interruption with unparalleled precision.
- Clutch Pins, Brake Pins and Locking Plates: Expertly crafted for connecting and stabilizing various components. The ingenious locking plates, embedded in pin grooves and securely fastened to the flywheel or machine body with screws, effectively prevent any axial movement of the pins.


IV. Working Principle
(I) Clutching Process
As external compressed air enters the clutch cylinder through the intake hole, it propels the piston into action. This motion, aided by friction pads, the clutch body, and a flat key, rotates the driven component, achieving clutch engagement and facilitating power transmission with unmatched efficiency.

(II) Braking Process
Upon ceasing the air supply, the piston retracts under spring force, and through the synergy of friction pads, clutch body, and flat key, the driven part is swiftly braked. With an astonishingly brief braking time of just 0.01 - 0.02 seconds, the equipment halts with remarkable speed and precision.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Ensure the installation holes for the four pins meet an H7 tolerance, and the hole center aligns parallel to the main shaft center. This precision is crucial for maintaining the installation accuracy and stability of the pins, ensuring long-term performance.

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

(III) Installation Sequence Suggestions
Customers have the flexibility to choose the installation sequence based on specific conditions. Typically, it is advisable to first install the clutch and brake ear plates, along with pins and locking plates, before integrating the clutch brake body.

(IV) Installation Notes for Square Pins
Square pins serve a vital function in eliminating installation size discrepancies of two pins and mitigating plate thermal deformation caused by clutch heating. Ensure the two flat surfaces of the square pin remain parallel to the radial direction of the ear plate for optimal efficacy.

(V) Sealing Requirements for Axial Air Intake
For axial air intake configurations, it is essential to install sealing caps at both ends of the clutch to effectively prevent gas leakage and maintain system integrity.

(VI) Check after Installation
Post-installation, ensure the clutch end and brake end move unimpeded to guarantee the smooth and reliable operation of both the clutch and brake systems.

Product Description

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each clutch sold by our esteemed Shandong Tenord Machinery Equipment Co., Ltd. has been meticulously inspected to ensure the highest quality. It is imperative that customers refrain from disassembling the clutch themselves. Unauthorized tampering may lead to damage for which we cannot assume liability. Should any quality issues arise, we urge you to contact us promptly for swift resolution.

(II) Friction Pad Replacement Method
The friction pads are essential yet consumable components that must be replaced after prolonged use and significant wear. Our design allows for easy replacement without dismantling the ear plates or clutch entirely. Follow these straightforward steps to replace them:
- Replacement without Air Supply: Simply loosen the clutch ear plate, remove the bolts and nuts securing the friction pads, replace them with new ones, and secure the assembly by tightening the bolts and nuts.
- Replacement with Air Supply: Similarly, loosen the brake ear plate and follow the same procedure to refresh the friction pads.

(III) Timing for Friction Pad Replacement
- In equipment such as presses, should the machine fall short of its rated capacity, inspect the friction pads to ascertain if replacement is warranted.
- Once the friction pad wear exceeds 50% of their original thickness, it is advisable to replace them promptly to maintain optimal performance.

VII. Product Selection
Selecting the right clutch is pivotal for the effective functionality of your equipment.
- Consequences of Improper Selection: A clutch too small will fail to meet capacity requirements; conversely, an oversized clutch unnecessarily inflates costs and causes overheating, accelerating friction pad wear and seal ring deterioration.
- Selection Suggestions: Explore our company's samples or consult with our expert technicians for tailored advice. We are committed to providing you with professional guidance to ensure you select the perfect clutch for your needs.

VIII. Safety Precautions
(I) Protection during High - speed Rotation
For your safety, never touch the clutch or any moving parts when the clutch is operating at high speeds. This is crucial to prevent injury.

(II) Protection from High Temperature
Direct contact with the clutch immediately after it stops is prohibited to prevent burns. Instead, allow at least a 30-minute cooling period before conducting any maintenance.

(III) Side Protection
To avert accidents from flying debris, avoid standing by the rotating clutch's side. Always ensure a protective cover is securely in place during operation.

(IV) Attention during Ventilation Operation
During ventilation and air-stopping procedures, refrain from touching the friction pads to prevent painful pinching injuries.

(V) Safety of Internal Structure
The clutch's internal springs require precise handling. Do not attempt disassembly without professional assistance to avoid injury. Only trained personnel should conduct any necessary internal work.
