Widely acclaimed across a spectrum of industries such as forging, printing, textile, welding, and shipbuilding, the KB Series stands out. It garners exceptional praise in sectors like metal and paper processing machinery, woodworking machinery, and fiber machinery.

II. Product Advantages
(I) Compact Structure
- Innovative Design: Featuring a small axial size and lightweight construction, the KB Series boasts low inherent rotational inertia. This effectively minimizes the equipment's overall size and weight without compromising performance, significantly enhancing operational efficiency.
(II) Safe and Reliable
- Asbestos-free Friction Material: Our friction material is meticulously engineered to be free from asbestos, eliminating potential health risks and aligning with modern safety and environmental standards, ensuring a safe and reliable user experience.
(III) Easy Maintenance
- Effortless Friction Pad Replacement: Designed for convenience, our friction pads can be replaced effortlessly without disassembling the clutch. This innovation dramatically reduces maintenance costs and time, enhances maintenance efficiency, and minimizes equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Advanced Disc Arc Design: The ingeniously crafted disc arc design significantly bolsters heat dissipation capabilities, lowering operational temperatures, prolonging product lifespan, and ensuring equipment stability even during prolonged high-load operations.
(V) Quick Response
- Rapid Operation: With lightning-fast clutching and braking capabilities, our clutch brakes deliver swift responses to meet the demands of various mechanical equipment, thereby boosting production efficiency.
(VI) Diverse Connection Methods
- Versatile Connectivity: Boasting multiple connection options, this product provides flexibility to adapt to diverse site requirements, ensuring a perfect match with various equipment.


III. Product Structure
The robust construction of the pneumatic clutch brake is composed of several key components:
- Clutch Body: The heart of the system, installed on the main shaft of the equipment. Its center hole size can be customized to meet specific customer requirements, with size ranges available in our detailed sample guide.
- Clutch Ear Plate and Brake Ear Plate: Ingeniously designed to connect seamlessly to the flywheel and machine body through four precisely placed pins, these components ensure the unwavering stability and smooth operation of the clutch and brake, providing a reliable and efficient performance.
- Friction Pads (Blocks): These critical components are pivotal in the seamless clutching and braking process, enabling precise power transmission and interruption, ensuring the machinery operates with unparalleled efficiency.
- Clutch Pins, Brake Pins and Locking Plates: Designed for robust connection and secure fixation of components, with locking plates meticulously embedded within pin grooves. They are firmly anchored to the flywheel or machine body using screws, effectively preventing any axial pin movement and ensuring dependable performance.


IV. Working Principle
(I) Clutching Process
When external compressed air gracefully enters the clutch cylinder through the intake hole, it propels the piston into action. This dynamic process, facilitated by friction pads, clutch body, and flat key, rotates the driven part, seamlessly engaging the clutch to transmit power efficiently.

(II) Braking Process
Upon halting the air supply, the piston deftly reverses under spring action. This swift transition, aided by friction pads, clutch body, and flat key, ensures the rapid braking of the driven part. In a mere 0.01 - 0.02 seconds, the equipment halts promptly, guaranteeing exceptional safety and control.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
To achieve optimal installation precision and stability, the hole tolerance for the four pins should adhere to H7 standards. Additionally, the hole centers must align parallelly with the main shaft center, ensuring impeccable accuracy.

(II) Geometric Tolerance and Roughness Requirements
Adhering strictly to national standards, the geometric tolerance and roughness of the center hole and keyway are crucial. Ensuring the customer's main shaft meets these precise standards enhances performance and reliability.

(III) Installation Sequence Suggestions
Customers have the flexibility to customize the installation sequence based on their unique circumstances. Typically, it is recommended to first install the clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body for seamless integration.

(IV) Installation Notes for Square Pins
Square pins are strategically used to address installation size discrepancies and mitigate plate thermal deformation from clutch heating. Ensure the two flat surfaces of the square pin remain parallel to the radial direction of the ear plate for optimal performance.

(V) Sealing Requirements for Axial Air Intake
For axial air intake configurations, it is imperative to install sealing caps at both ends of the clutch. This prevents any potential gas leakage, preserving the integrity and functionality of the system.

(VI) Check after Installation
Post-installation, it is essential to verify that both the clutch end and brake end operate freely. This ensures the clutch and brake function optimally, maintaining the machine's high performance and reliability.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every clutch that leaves Shandong Tenord Machinery Equipment Co., Ltd. has been meticulously inspected for quality and performance. We strongly advise against any unauthorized disassembly of the clutch, as it may void responsibility for subsequent damages. Should you encounter any quality issues, please notify us promptly for a swift resolution.

(II) Friction Pad Replacement Method
Friction pads, as integral yet consumable parts of the machine, require timely replacement when wear becomes apparent from extended use. At Shandong Tenord, we've crafted the friction pad replacement process to be hassle-free, eliminating the need for detaching ear plates or the clutch itself. Follow these straightforward steps to ensure continued operational excellence:
- Replacement without Air Supply: Simply loosen the clutch's ear plate, remove the securing bolts and nuts, replace with fresh friction pads, and ensure all bolts and nuts are securely tightened.
- Replacement with Air Supply: Begin by loosening the brake ear plate, and proceed with the steps outlined above to install new friction pads.

(III) Timing for Friction Pad Replacement
- For any equipment like presses, assess the need for friction pad replacement when the machine underperforms and fails to meet its rated capacity.
- When the wear on friction pads surpasses fifty percent of their original state, it is imperative for users to replace them promptly to maintain optimal functionality.

VII. Product Selection
Selecting the perfect clutch for your machinery is pivotal, as this component is the heartbeat of operational efficiency.
- Consequences of Improper Selection: Opting for a clutch that is undersized could lead to underperformance, while an oversized clutch may drive up costs and contribute to overheating, hastening wear on friction pads and aging of sealing rings.
- Selection Suggestions: Refer to our comprehensive company product samples or consult directly with our seasoned technicians to receive tailored selection advice, ensuring the most suitable choice for your equipment.

VIII. Safety Precautions
(I) Protection during High-Speed Rotation
To safeguard against potential hazards, it is imperative to refrain from touching the clutch or allowing objects to come into contact with it while it spins at high velocity.

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

(III) Side Protection
To prevent accidents from ejected objects, never stand beside a spinning clutch. Implementing a protective cover during operation is essential for safety.

(IV) Attention during Ventilation Operation
During the processes of venting and halting airflow, ensure fingers are kept away from friction pads to prevent injury.

(V) Safety of Internal Structure
The internal spring mechanism of the clutch is intricate and delicate. Refrain from unauthorized disassembly to avoid harm. Any necessary disassembly should be executed exclusively by qualified professionals.
