(VI) Diverse Connection Methods
- Versatile Connection Options: Boasting multiple adaptable connection methods tailored to distinct site requirements, it offers robust adaptability, seamlessly integrating with a wide array of equipment.


III. Product Structure
The pneumatic clutch brake is composed of the following key components:
- Clutch Body: Mounted on the main shaft, customizable center hole sizes (refer to the sample) make it the core component ensuring peak clutch performance.
- Clutch Ear Plate and Brake Ear Plate: Securely connected to the equipment's flywheel and machine body via four pins to guarantee clutch and brake stability.
- Friction Pads (Blocks): These essential components are pivotal in the clutching and braking processes, enabling seamless power transmission and interruption. The friction pads ensure smooth operation and reliable control of your machinery.
- Clutch Pins, Brake Pins, and Locking Plates: Integral for connecting and securing various components, the locking plates fit snugly into pin grooves and are securely fastened to the flywheel or machine body with screws, expertly preventing any axial pin movement.


IV. Working Principle
(I) Clutching Process
External compressed air flows into the clutch cylinder through the strategically designed intake hole, propelling the piston into motion. This action, facilitated by the friction pads, clutch body, and flat key, initiates the driven part's rotation, thereby engaging the clutch and ensuring efficient power transmission.

(II) Braking Process
Once the air supply ceases, a spring-driven piston movement occurs in the reverse direction. This rapid reaction, in conjunction with the friction pads, clutch body, and flat key, promptly brakes the driven part. The astounding braking time of merely 0.01 to 0.02 seconds guarantees fast and reliable equipment stoppage, enhancing operational safety.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Ensure the hole tolerance for the installation of the four pins meets the precise H7 standard, while maintaining the hole center's parallel alignment with the main shaft center. This precision guarantees the accurate and stable installation of pins, vital for optimal machine performance.

(II) Geometric Tolerance and Roughness Requirements
Conformation to national standards is imperative for the geometric tolerance and roughness of the center hole and keyway. Similarly, the main shaft's geometric tolerance and roughness should align with specified criteria to enhance your product's performance and reliability.

(III) Installation Sequence Suggestions
Installation sequence can be adjusted to meet specific needs. Generally, it is advisable to initiate with the installation of clutch and brake ear plates, followed by pins and locking plates, and conclude with the assembly of the clutch brake body for a streamlined process.

(IV) Installation Notes for Square Pins
Square pins are utilized to counteract installation size discrepancies of two pins and combat plate thermal deformation due to clutch heating. Pay close attention to ensure the two flat surfaces of the square pin remain parallel to the ear plate's radial direction for precision.

(V) Sealing Requirements for Axial Air Intake
For an axial air intake configuration, it is essential to fit sealing caps at both clutch ends. This precaution effectively prevents any potential gas leakage, ensuring the system's airtight integrity.

(VI) Check after Installation
Post-installation, verify that both the clutch end and brake end have unobstructed movement. This validation is crucial to confirm the efficient and normal operation of your clutch and brake system.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every clutch we offer is subject to rigorous quality checks, ensuring top-grade performance. Unauthorized disassembly will nullify our responsibility for any ensuing damages. Should any issues arise, contact us promptly for swift resolution.

(II) Friction Pad Replacement Method
Friction pads, as pivotal consumables, demand timely replacement after extensive use. Our intuitive design allows for effortless pad replacement without the need for dismantling the ear plates or clutch. Follow this straightforward procedure:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Remove the bolts and nuts securing the pads, swap in the new friction pads, and then securely retighten the bolts and nuts.
- Replacement with Air Supply: Similarly, loosen the brake ear plate and follow the aforementioned steps to replace with new friction pads.

(III) Timing for Friction Pad Replacement
- In machines like presses, diminished performance signals the need to check and possibly replace friction pads.
- Replacement is advised when wear exceeds fifty percent of the friction pad's original thickness, ensuring optimal efficiency.

VII. Product Selection
The choice of clutch is vital to the functionality of your equipment. Proper selection ensures efficiency and longevity.
- Consequences of Improper Selection: An undersized clutch fails to deliver required capacity, while an oversized one escalates costs and risks overheating, hastening wear and seal deterioration.
- Selection Suggestions: Rely on our detailed samples or consult our expert technicians for tailored advice, ensuring the perfect match for your needs.

VIII. Safety Precautions
(I) Protection during High - speed Rotation
Avoid contact with the high-speed rotating clutch to prevent any potential hazards.

(II) Protection from High Temperature
To prevent burns, refrain from touching the clutch immediately post-operation. Allow it to cool for about 30 minutes before proceeding with maintenance.

(III) Side Protection
Steer clear of the clutch's periphery during operation to avert accidents from projected objects. Always ensure a protective cover is in place during use.

(IV) Attention during Ventilation Operation
During air operations, keep fingers clear from friction pads to prevent pinching injuries.

(V) Safety of Internal Structure
The clutch's internal springs are not for unauthorized tampering. Disassembly should be strictly handled by trained professionals to avoid harm.
