This versatile product finds widespread utility in industries such as forging, printing, textile, welding, and shipbuilding. It has garnered accolades, particularly excelling in sectors like metal processing, paper processing machinery, woodworking machinery, and fiber machinery.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Light Weight: The minimal axial size and reduced weight, coupled with low inherent rotational inertia, significantly trim down the equipment's volume and weight. This translates into a boost in operational efficiency while maintaining superior performance.
(II) Safe and Reliable
- Asbestos-free Friction Material: Free from asbestos components, the friction material ensures no health hazards, aligning with modern environmental and safety standards, delivering a safer, more dependable user experience.
(III) Easy Maintenance
- Simple Friction Pad Replacement: The friction pads are effortlessly replaceable without dismantling the clutch, massively cutting down on maintenance costs and time, enhancing equipment maintenance efficacy, and minimizing downtime.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: The innovative disc arc design greatly enhances the product's heat dissipation capacity, effectively lowering operational temperatures, prolonging product service life, and ensuring equipment stability during prolonged high-load operations.
(V) Quick Response
- Fast Clutching and Braking: With a lightning-fast response time, it swiftly executes clutching and braking functions, meeting diverse mechanical equipment demands for rapid responsiveness, thereby boosting production efficiency.
(VI) Diverse Connection Methods
- Flexible Connection Options: Featuring numerous connection methods, it offers flexibility tailored to various site requirements, demonstrating strong adaptability for seamless integration with diverse equipment.


III. Product Structure
The pneumatic clutch brake is predominantly constituted of the following components:
- Clutch Body: Mounted on the equipment's main shaft, its center hole size can be customized per customer specifications (refer to the sample for size range), serving as the pivotal element of the clutch.
- Clutch Ear Plate and Brake Ear Plate: These integral components are meticulously connected to the flywheel and machine body via four pivotal pins, ensuring seamless and stable operation of both the clutch and brake systems.
- Friction Pads (Blocks): Crucially integral to the clutching and braking processes, these pads are pivotal in enabling the smooth transmission and precise interruption of power.
- Clutch Pins, Brake Pins, and Locking Plates: Essential for the secure connection and stabilization of various components. Notably, the locking plates are strategically embedded within pin grooves and securely affixed to the flywheel or machine body with screws, preventing any unwanted axial pin movement.


IV. Working Principle
(I) Clutching Process
External compressed air is channeled into the clutch cylinder through a specialized intake hole, driving the piston into motion. Through the integral action of friction pads, the clutch body, and a flat key, the driven part rotates, facilitating clutch engagement and seamless power transmission.

(II) Braking Process
Upon halting the air supply, the piston retracts in opposite direction due to spring force, executing a swift braking action via friction pads, clutch body, and flat key. The braking response is impressively swift, between 0.01 - 0.02 seconds, ensuring rapid cessation of equipment operation.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Installation requires the hole tolerance for the four pins to adhere to H7 standards, with the hole center maintaining parallel alignment with the main shaft center to ensure superior installation precision and reliability.

(II) Geometric Tolerance and Roughness Requirements
Both the geometric tolerance and surface roughness of the center hole and keyway must strictly adhere to national standards. Additionally, the geometric tolerance and roughness of the customer's main shaft must meet requisite standards to enhance overall product performance.

(III) Installation Sequence Suggestions
Installation can be customized to suit varying scenarios. Generally, it's advisable to first install the clutch and brake ear plates, pins, and locking plates, followed by the assembly of the clutch brake body.

(IV) Installation Notes for Square Pins
The application of square pins is crucial in neutralizing installation size discrepancies between two pins and mitigating plate thermal distortion due to clutch heating. It is imperative that the two flat surfaces of the square pin align parallelly with the radial orientation of the ear plate.

(V) Sealing Requirements for Axial Air Intake
For systems utilizing axial air intake, sealing caps must be meticulously installed at both ends of the clutch to effectively prevent any potential gas leakage.

(VI) Check after Installation
Post-installation, it's vital to ensure that both the clutch end and brake end exhibit free movement, thereby guaranteeing the optimal and unhindered operation of the clutch and brake systems.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every clutch we deliver to you has passed through rigorous quality assurance processes. It is imperative that customers refrain from unauthorized disassembly of the clutch, as any resultant damage from such actions will void the responsibility of Shandong Tenord Machinery Equipment Co., Ltd. For any concerns regarding quality, we urge you to contact us promptly, and we guarantee a swift and satisfactory resolution.

(II) Friction Pad Replacement Method
Our product's friction pads, being vital yet consumable components, require timely replacement upon evident wear due to prolonged use. The process is designed to be straightforward, eliminating the need to disassemble the ear plates or clutch, thereby saving you time and effort. Here is how you can replace them effortlessly:
- Replacement without Air Supply: First, gently loosen the clutch ear plate. Proceed by removing the bolts and nuts holding the worn friction pads in place. Swap in the new pads, ensuring they are securely fastened by re-tightening the bolts and nuts.
- Replacement with Air Supply: Start by loosening the brake ear plate, then follow the aforementioned steps to seamlessly replace the old friction pads with new ones.

(III) Timing for Friction Pad Replacement
- In high-performance machinery like presses, if you notice a drop in achieving the rated capacity, it is a strong indicator that the friction pads require replacement.
- As soon as the wear of the friction pads surpasses fifty percent of their original thickness, it's crucial to replace them promptly to ensure optimal performance.

VII. Product Selection
Selecting the right clutch is vital for the seamless operation of your equipment, ensuring you harness its full potential.
- Consequences of Improper Selection: An undersized clutch could fail to meet the operational requirements. Conversely, an oversized clutch not only escalates equipment costs but also risks overheating, leading to accelerated wear on the friction pads and premature aging of the sealing rings.
- Selection Suggestions: We offer tailored guidance to help you choose the ideal clutch. You can either select from our comprehensive range of samples or consult our expert technicians for personalized advice, ensuring a perfect match for your requirements.

VIII. Safety Precautions
(I) Protection during High - speed Rotation
To ensure safety, never attempt to touch the clutch or bring any objects near it while it is in high-speed rotation, as this poses significant danger.

(II) Protection from High Temperature
Avoid direct contact with the clutch immediately after it ceases rotation to prevent burns. Allow approximately 30 minutes for the clutch to cool to room temperature before commencing any maintenance activities.

(III) Side Protection
Standing beside a rotating clutch exposes you to risks from potential projectiles. Always ensure a protective cover is in place during its operation to guard against such hazards.

(IV) Attention during Ventilation Operation
During ventilation or when stopping air supply, refrain from touching the friction pads with fingers as this could result in injury from pinching.

(V) Safety of Internal Structure
The clutch houses internal springs that should not be tampered with by unqualified individuals. Any necessary disassembly must be performed by skilled professionals to avoid injury.
