This remarkable product finds its place in various industries including forging, printing, textile, welding, and shipbuilding. It is particularly acclaimed in sectors such as metal processing, paper machinery, woodworking machinery, and fiber machinery, enjoying widespread commendation.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Lightweight: Boasting a minimal axial size and featherlight weight, this product's low inherent rotational inertia contributes to a reduction in overall equipment volume and weight, enhancing operational efficiency without compromising on performance.
(II) Safe and Reliable
- Asbestos-free Friction Material: Our eco-conscious friction material is free from asbestos, eliminating potential health hazards and aligning with modern environmental safety standards, offering users a secure and dependable experience.
(III) Easy Maintenance
- Effortless Friction Pad Replacement: Simplified replacement of friction pads without disassembling the clutch reduces maintenance costs and time, significantly boosting maintenance efficiency and minimizing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Ingenious Disc Arc Design: Our unique disc arc design dramatically enhances heat dissipation, effectively lowering operational temperatures, extending product lifespan, and ensuring stability during prolonged high-load operations.
(V) Quick Response
- Swift Clutching and Braking: Experience rapid response times with our product's ability to swiftly execute clutching and braking functions, meeting the demands for quick responsiveness and augmenting production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Equipped with multiple connection methods, this product can be flexibly adapted to varying site requirements, showcasing its robust adaptability and perfect integration with diverse equipment.


III. Product Structure
The pneumatic clutch brake is comprised of the following key components:
- Clutch Body: Mounted on the equipment's main shaft, the central hole size is customizable as per customer specifications (size range available in the sample), serving as the clutch's core component.
- Clutch Ear Plate and Brake Ear Plate: These vital components are meticulously linked to the flywheel and machine body through four robust pins, ensuring the seamless and reliable functionality of the clutch and brake systems.
- Friction Pads (Blocks): Essential in the clutching and braking mechanism, these pads are pivotal in enabling the smooth transmission and precise interruption of power, ensuring optimal performance.
- Clutch Pins, Brake Pins, and Locking Plates: These components serve as the backbone for connecting and steadfastly securing various parts. Notably, the locking plates are strategically embedded within pin grooves and firmly fastened on the flywheel or machine body with screws, preventing any axial displacement of the pins.


IV. Working Principle
(I) Clutching Process
External compressed air is introduced into the clutch cylinder via the intake hole, prompting the piston to engage. This action, transmitted through friction pads, the clutch body, and the flat key, rotates the driven part, achieving clutch engagement and the effective transmission of power.

(II) Braking Process
Upon cessation of air supply, the piston swiftly moves in reverse under spring tension. This action, mediated by friction pads, the clutch body, and the flat key, promptly halts the driven part. The braking process occurs in just 0.01 - 0.02 seconds, ensuring rapid equipment stoppage.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Precision is paramount, with hole tolerances set at H7. The hole center must be perfectly parallel to the main shaft center, guaranteeing the installation's precision and stability.

(II) Geometric Tolerance and Roughness Requirements
Strict adherence to national standards for geometric tolerance and roughness in the center hole and keyway is crucial. The customer's main shaft must also meet these exacting standards to enhance overall product performance.

(III) Installation Sequence Suggestions
Installers can tailor the sequence based on specific conditions. Typically, commence with the clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body.

(IV) Installation Notes for Square Pins
Square pins play a critical role in mitigating installation size discrepancies and thermal deformation. Ensure that the two flat surfaces of each square pin are aligned parallel to the radial orientation of the ear plate.

(V) Sealing Requirements for Axial Air Intake
For axial air intake configurations, it's imperative to install sealing caps at both clutch ends to effectively prevent gas leakage.

(VI) Check after Installation
Post-installation, verify that both the clutch end and brake end can move unimpeded, ensuring the clutch and brake operate smoothly and efficiently.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every clutch from Shandong Tenord Machinery Equipment Co., Ltd. undergoes rigorous quality checks to guarantee excellence. Customers are cautioned against unauthorized disassembly of the clutch, as any resultant damages will not be covered under our responsibility. Should you encounter any quality concerns, promptly inform us so we can address and resolve the issue swiftly.

(II) Friction Pad Replacement Method
The friction pads, essential yet consumable components, require timely replacement after extensive machine use when noticeable wear occurs. Replacing these pads in our products is straightforward and doesn't necessitate dismantling the ear plates or clutch. Follow these specific methods for a seamless replacement experience:
- Replacement without Air Supply: Begin by loosening the clutch ear plate, then proceed to remove the bolts and nuts that secure the friction pads. Replace the worn pads with new ones, ensuring to tighten all bolts and nuts securely.
- Replacement with Air Supply: Loosen the brake ear plate, then repeat the aforementioned steps to efficiently replace the worn friction pads with new ones.

(III) Timing for Friction Pad Replacement
- For equipment like presses, if the machine's performance doesn't meet the rated capacity, evaluate the condition of the friction pads to determine if replacement is necessary.
- When the friction pads exhibit wear exceeding half their original thickness, it is crucial for customers to undertake timely replacement to maintain optimum performance.

VII. Product Selection
Selecting the right clutch is vital for the effective operation of your equipment. Ensure an appropriate fit to achieve maximum performance.
- Consequences of Improper Selection: An undersized clutch fails to meet capacity demands, while an oversized clutch unnecessarily escalates equipment costs and can lead to overheating, accelerated pad wear, and quicker seal ring aging.
- Selection Suggestions: Customers are encouraged to refer to our company's samples or consult our specialized technicians for tailored advice. We are committed to providing expert guidance for optimal clutch selection.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
During high-speed rotation, avoid contact with the clutch using hands or objects to prevent potential hazards.

(II) Protection from High Temperature
Avoid direct hand contact with the clutch immediately post-rotation to prevent burns. A half-hour cooling period is advised before any maintenance, allowing the clutch to return to room temperature.

(III) Side Protection
Standing at the side of a rotating clutch is prohibited to prevent accidents from flying debris. A protective cover should be installed for enhanced safety during operation.

(IV) Attention during Ventilation Operation
During the ventilation and air-stopping process, keep fingers away from friction pads to avoid injury from pinching.

(V) Safety of Internal Structure
Our clutches contain internal springs, necessitating professional handling for any disassembly to prevent injury. Unauthorized disassembly is strictly discouraged.
