(III) Easy Maintenance
- Effortless Friction Pad Replacement: Swap out friction pads with ease, no disassembly required, drastically slashing maintenance costs and time. This leads to heightened maintenance efficiency and reduced equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Innovative Disc Arc Design: The distinct disc arc design enhances the product's heat dissipation prowess, effectively lowering operational temperatures. This extension of service life ensures stability during prolonged high-load operations.
(V) Quick Response
- Rapid Clutching and Braking: Experience lightning-fast response speeds with swift clutching and braking functionalities, perfectly catering to the diverse quick-response demands of mechanical equipment, thereby boosting production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: With a variety of connection methods available, adaptability is key, allowing for seamless integration with varying equipment and site-specific requirements.


III. Product Structure
The intricate pneumatic clutch brake comprises several key components:
- Clutch Body: Mounted on the main shaft of the equipment, the center hole size is fully customizable per customer specifications (refer to the sample for size range). As the heart of the clutch system, it plays a pivotal role.
- Clutch Ear Plate and Brake Ear Plate: Expertly connected to the flywheel and the robust machine body via four precision pins, these vital components ensure seamless and stable operations for your clutch and brake, offering unparalleled reliability.
- Friction Pads (Blocks): Integral to the clutching and braking mechanism, these friction pads expertly facilitate the smooth transmission and interruption of power, enhancing performance with precision.
- Clutch Pins, Brake Pins, and Locking Plates: Essential for the seamless connection and secure fixation of various components. The innovative locking plates are designed to nestle ingeniously within pin grooves and are secured firmly on the flywheel or machine body with screws, preventing any axial pin movement and ensuring optimal functionality.


IV. Working Principle
(I) Clutching Process
Harnessing the power of external compressed air, this process initiates as air enters the clutch cylinder through a strategically placed intake hole, propelling the piston into motion. Through the adept engagement of friction pads, clutch body, and flat key, the driven part swings into action, seamlessly engaging the clutch and ensuring a smooth transmission of power.

(II) Braking Process
Upon halting the air supply, the innovative spring mechanism triggers the piston to reverse its direction, expertly engaging the friction pads, clutch body, and flat key to swiftly brake the driven part. With an astonishingly rapid braking time of only 0.01 - 0.02 seconds, this ensures your equipment halts swiftly and safely.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Ensure precision with an H7 tolerance for the pin installation holes, while maintaining parallel alignment with the main shaft center. This meticulous attention to detail guarantees the pin's stability and installation accuracy, amplifying reliability.

(II) Geometric Tolerance and Roughness Requirements
All geometric tolerances and surface roughness of center holes and keyways are crafted to meet stringent national standards. The customer's main shaft must also adhere to these exacting standards, optimizing product performance and ensuring superior operation.

(III) Installation Sequence Suggestions
Tailor your installation sequence according to specific situations. Typically, begin with the precise installation of clutch and brake ear plates, followed by pins and secure locking plates. Conclude with the assembly of the clutch brake body for a flawless setup.

(IV) Installation Notes for Square Pins
Square pins are integral for correcting installation size discrepancies and addressing thermal deformation from clutch heating. Ensure the two flat surfaces of the square pin align perfectly parallel to the ear plate's radial direction for optimal performance.

(V) Sealing Requirements for Axial Air Intake
For axial air intake, it's essential to outfit both ends of the clutch with sealing caps, preventing any potential gas leakage and ensuring airtight integrity.

(VI) Check after Installation
Post-installation, verify that the clutch end and brake end glide freely, ensuring the clutch and brake operate smoothly and efficiently, delivering the high performance you expect.

Friction pads, subject to wear and tear over time, are essential components of our machinery. While designed for durability, timely replacement is vital. Our friction pad replacement is engineered for simplicity, negating the need to dismantle ear plates or the clutch itself. Follow these straightforward steps for an effortless replacement:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Proceed by removing the bolts and nuts securing the friction pads. Insert the new pads and firmly secure with bolts and nuts.
- Replacement with Air Supply: Loosen the brake ear plate and mirror the steps above to install new friction pads.

(III) Timing for Friction Pad Replacement
- In machinery like presses, ensure the equipment maintains its rated capacity by inspecting the friction pads for timely replacement.
- Replace friction pads promptly when wear surpasses 50% of their original state to ensure optimal functionality.

VII. Product Selection
Choosing the right clutch is paramount for operational efficiency. It is a key component that ensures the seamless performance of your equipment.
- Consequences of Improper Selection: A misfit clutch, whether undersized or oversized, can lead to significant issues. An undersized clutch won't meet capacity requirements, while an oversized one elevates costs and induces overheating, accelerating friction pad and seal wear.
- Selection Suggestions: Leverage our company's extensive samples or consult with our experts for tailored advice. We offer professional guidance to ensure your selection is ideal.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
For your safety, avoid physical contact with the clutch during high-speed operations. Adhering to this precaution prevents hazardous incidents.

(II) Protection from High Temperature
After operation, the clutch remains hot. Avoid direct contact immediately post-rotation to prevent burns. Allow a cooling period of approximately 30 minutes before commencing any maintenance.

(III) Side Protection
To safeguard against potential accidents, refrain from standing beside the rotating clutch. Utilize a protective cover during operation for added security.

(IV) Attention during Ventilation Operation
During ventilation or air-stopping, ensure fingers are kept clear of the friction pads to avoid entrapment injuries.

(V) Safety of Internal Structure
Our clutches contain internal springs for optimal function. Unauthorized disassembly poses risks of injury; hence, any required disassembly should be performed by qualified professionals only.
