(I) Application Fields
A staple in industries like forging, printing, textile, welding, and shipbuilding, the KB Series has earned accolades particularly in metal processing, paper processing, woodworking, and fiber machinery sectors for its superior performance.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Light Weight: The minimized axial dimensions and lightweight design significantly reduce the equipment's overall volume and weight, optimizing operational efficiency and performance.
(II) Safe and Reliable
- Asbestos-free Friction Material: Designed with health and safety in mind, the asbestos-free friction material meets modern environmental standards, ensuring a safer user experience.
(III) Easy Maintenance
- Simple Friction Pad Replacement: Effortlessly replace friction pads without dismantling the clutch, saving time and costs, enhancing maintenance efficiency, and minimizing downtime.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: The innovative disc arc design maximizes heat dissipation, lowering operational temperatures, prolonging product life, and maintaining equipment stability during extended high-load operations.
(V) Quick Response
- Fast Clutching and Braking: Rapid response speed ensures swift clutching and braking, catering to the demands of various mechanical equipment and boosting production efficiency.
(VI) Diverse Connection Methods
- Flexible Connection Options: With multiple adaptable connection methods, the product easily aligns with different site requirements, showcasing its versatility and perfect compatibility with various equipment.


III. Product Structure
The pneumatic clutch brake is meticulously constructed from the following components:
- Clutch Body: Mounted on the equipment's main shaft, the center hole size is customizable (refer to the sample size range). It serves as the clutch's pivotal component.
- Clutch Ear Plate and Brake Ear Plate: Securely connected to the flywheel and machine body via four pins, these plates ensure the stable operation of both the clutch and brake.
- Friction Pads (Blocks): These indispensable components are pivotal in the clutching and braking process, expertly facilitating the transmission and interruption of power, ensuring seamless operation.
- Clutch Pins, Brake Pins, and Locking Plates: Essential for the secure connection and fixation of various components. Notably, the locking plates are strategically embedded in the pin grooves and are firmly affixed to the flywheel or machine body with screws, effectively preventing any axial movement of the pins.


IV. Working Principle
(I) Clutching Process
External compressed air enters the clutch cylinder through the intake hole, activating the piston to move. Through the interplay of friction pads, clutch body, and flat key, the driven part rotates, facilitating clutch engagement and enabling seamless power transmission.

(II) Braking Process
Upon ceasing the air supply, the piston retracts under the spring's force. This action, through the friction pads, clutch body, and flat key, swiftly brakes the driven part. With an impressive braking time of just 0.01 - 0.02 seconds, the equipment ensures rapid stopping capabilities.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
The installation holes for the four pins should adhere to an H7 tolerance, with the hole center precisely parallel to the main shaft center, ensuring installation accuracy and pin stability.

(II) Geometric Tolerance and Roughness Requirements
The geometric tolerance and roughness of both the center hole and keyway must strictly conform to national standards. Similarly, the customer's main shaft should meet these requirements to enhance product performance.

(III) Installation Sequence Suggestions
Customers are encouraged to select the installation sequence based on specific needs. Generally, it is advisable to initially install the clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body installation.

(IV) Installation Notes for Square Pins
Square pins are utilized to correct installation size errors of two pins and counteract the plate's thermal deformation due to 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.

(V) Sealing Requirements for Axial Air Intake
For axial air intake configurations, sealing caps must be installed at both ends of the clutch to prevent any gas leakage, ensuring optimal performance.

(VI) Check after Installation
Post-installation, it is essential that the clutch end and brake end move freely to guarantee the clutch and brake's smooth and normal operation.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every clutch sold by Shandong Tenord Machinery Equipment Co., Ltd. is rigorously tested to ensure top-tier performance. Customers must refrain from unauthorized disassembly to prevent potential damage; such actions negate our responsibility for repairs. Should you encounter any quality concerns, kindly notify us promptly for swift resolution.

(II) Friction Pad Replacement Method
Given that friction pads are consumable elements, they necessitate replacement after prolonged use and significant wear. Our design simplifies the replacement process—no need to detach the ear plates or clutch itself. Follow these straightforward steps for seamless maintenance:
- Replacement without Air Supply: Carefully loosen the clutch ear plate, then remove the bolts and nuts securing the friction pads. Replace them with new pads and secure tightly.
- Replacement with Air Supply: Begin by loosening the brake ear plate and follow the same procedure to swap in new friction pads.

(III) Timing for Friction Pad Replacement
- For devices like presses, if operation falls below rated capacity, inspect the friction pads as a potential cause for replacement.
- When the wear on friction pads surpasses 50% of their original state, it is imperative for customers to initiate a timely replacement.

VII. Product Selection
Selecting the right clutch is vital for optimal equipment function. A well-chosen clutch ensures efficient performance and longevity.
- Consequences of Improper Selection: A clutch that is too small will fail to deliver required capacity, while an oversized clutch inflates costs, risks overheating, and accelerates wear on friction pads and seals.
- Selection Suggestions: Browse our catalog or connect with our expert technicians for tailored advice. We are dedicated to guiding you toward the ideal selection to suit your needs.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
Never touch the clutch or introduce objects near it during high-speed rotation to prevent serious hazards.

(II) Protection from High Temperature
Avoid direct contact with the clutch immediately post-operation to prevent burns. Wait approximately 30 minutes for the temperature to drop to room level before conducting any maintenance.

(III) Side Protection
Standing beside a rotating clutch poses significant risk. Always install a protective cover to safeguard against potential projectile injuries.

(IV) Attention during Ventilation Operation
Refrain from touching friction pads with fingers during air supply or cessation processes to prevent pinching injuries.

(V) Safety of Internal Structure
The internal spring mechanism of the clutch demands professional handling—avoid unsanctioned disassembly to prevent injury. Professional assistance is necessary for any required internal access.
