(I) Application Fields
Our clutch brake excels across diverse sectors, including forging, printing, textile, welding, and shipbuilding. It garners exceptional acclaim in metal processing, paper machinery, woodworking machinery, and fiber machinery sectors.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Light Weight: This design prioritizes minimal axial size and light weight, with low inherent rotational inertia. Such characteristics effectively reduce equipment volume and weight while enhancing performance, thereby boosting operational efficiency.
(II) Safe and Reliable
- Asbestos-free Friction Material: Our friction materials are entirely free from asbestos, negating its health risks. This aligns with modern environmental and safety standards, ensuring a safer, more reliable user experience.
(III) Easy Maintenance
- Simple Friction Pad Replacement: Enjoy hassle-free friction pad replacement without disassembling the clutch, significantly cutting down on maintenance costs and time, elevating maintenance efficiency, and reducing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: Our unique disc arc design significantly enhances heat dissipation, effectively lowering operating temperatures, extending product life, and maintaining equipment stability under prolonged high-load conditions.
(V) Quick Response
- Fast Clutching and Braking: Experience rapid response and swift clutching and braking functions, fulfilling mechanical equipment's fast-response needs and boosting production efficiency.
(VI) Diverse Connection Methods
- Flexible Connection Options: Equipped with versatile connection methods, our clutch brake can adapt to various site requirements, offering strong adaptability and seamless compatibility with diverse equipment.


III. Product Structure
The pneumatic clutch brake is composed of key components, including:
- Clutch Body: This core component, mounted on the equipment's main shaft, features a customizable center hole size to meet customer specifications (refer to size range in the sample), forming the heart of the clutch.
- Clutch Ear Plate and Brake Ear Plate: Ingeniously connected to the flywheel and machine body of the equipment through four precision-engineered pins, this design ensures the seamless and stable operation of both the clutch and brake, offering reliability in every press.
- Friction Pads (Blocks): These essential components are the heart of the clutching and braking processes, skillfully facilitating the transmission and interruption of power with precision and efficiency.
- Clutch Pins, Brake Pins, and Locking Plates: Meticulously utilized for the secure connection and fixation of various components. The locking plates, in particular, are expertly embedded within pin grooves and fastened to the flywheel or machine body via screws, firmly preventing any axial movement of the pins and ensuring steadfast operation.


IV. Working Principle
(I) Clutching Process
External compressed air elegantly enters the clutch cylinder through the intake hole, propelling the piston to initiate movement. By means of the friction pads, clutch body, and flat key, the driven part is effectively rotated, achieving clutch engagement and facilitating smooth power transmission.

(II) Braking Process
Upon halting the air supply, the piston, driven by the spring's force, moves in reverse. Through the friction pads, clutch body, and flat key, the driven part is efficiently braked with exceptional speed. The braking process is executed in a mere 0.01 - 0.02 seconds, guaranteeing rapid cessation of equipment operation.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
The precision hole tolerance for the installation of the four pins is H7, ensuring that the hole center is meticulously parallel to the main shaft center. This specification guarantees the installation precision and stability of the pins, ensuring impeccable equipment performance.

(II) Geometric Tolerance and Roughness Requirements
The geometric tolerance and roughness of the center hole and keyway are strictly aligned with national standards. Additionally, the geometric tolerance and roughness of the customer's main shaft must meet the requisite criteria to enhance product performance and integrity.

(III) Installation Sequence Suggestions
Customers have the flexibility to select the installation sequence that best suits their situation. Generally, it is advisable to begin with the installation of the clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body for optimal setup.

(IV) Installation Notes for Square Pins
Square pins are strategically employed to counter installation size discrepancies between two pins and the thermal deformation of plates caused by clutch heating. It is crucial to ensure that the two flat surfaces of the square pin are aligned parallel to the radial direction of the ear plate for precise assembly.

(V) Sealing Requirements for Axial Air Intake
For axial air intake scenarios, it is imperative to install sealing caps at both ends of the clutch to effectively prevent any potential gas leakage, maintaining the integrity of the system.

(VI) Check after Installation
Post-installation, it is essential to verify that the clutch end and brake end have the freedom of movement. This ensures the smooth and normal operation of the clutch and brake systems, delivering exceptional performance.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
At Shandong Tenord Machinery Equipment Co., Ltd., every clutch is crafted to perfection, subjected to rigorous quality checks before reaching you. Our policy strictly prohibits private disassembly of the clutch as it may lead to irreversible damage, releasing us from any resulting liability. Should you encounter any quality concerns, promptly reach out to us, and we'll address them with utmost urgency.

(II) Friction Pad Replacement Method
The friction pads are critical yet consumable components of your machine. Over time, extensive use leads to wear and tear, signaling the need for replacement. Fortunately, replacing these pads is a breeze with our intuitive design—no need to disassemble clutch or ear plates. Here's how simple it is:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Remove the bolts and nuts securing the worn friction pads, replace them with fresh ones, and fasten everything securely.
- Replacement with Air Supply: Loosen the brake ear plate and follow the same straightforward steps to ensure your machine runs perfectly.

(III) Timing for Friction Pad Replacement
- For machines like presses, if they aren't achieving their full potential, inspect the friction pads—they might need replacing.
- Should the wear on your friction pads surpass 50% of their original state, immediate replacement is advised to maintain optimal performance.

VII. Product Selection
Selecting the right clutch is pivotal to maximizing your equipment's potential and longevity.
- Consequences of Improper Selection: A clutch that's too small will underperform; one too large will not only inflate costs but also risk overheating, speeding up pad wear and seal degradation.
- Selection Suggestions: Consult our comprehensive company catalog or engage with our expert technicians. They're ready to provide you with tailored advice to suit your specific needs.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
When in high-speed operation, keep hands and objects away from the clutch to ensure safety and prevent any mishaps.

(II) Protection from High Temperature
Refrain from touching the clutch immediately post-operation to avoid burns. Allow a cooling period of approximately 30 minutes before maintenance.

(III) Side Protection
Never position yourself next to a spinning clutch. A robust protective cover is essential to guard against debris or accidents.

(IV) Attention during Ventilation Operation
During air-related processes, keep fingers clear of the friction pads to prevent injury.

(V) Safety of Internal Structure
The clutch contains internal springs and should not be disassembled casually to avoid harm. Professional intervention is required for any necessary disassembly.
