(I) Application Fields
The KB Series is celebrated for its wide application across industries like forging, printing, textiles, welding, and shipbuilding. It garners accolades particularly in metal processing, paper machinery, woodworking, and fiber machinery sectors, delivering unparalleled performance.

II. Product Advantages
(I) Compact Structure
- Small Axial Size and Light Weight: Engineered with a compact axial size and lightweight build, the design minimizes inherent rotational inertia. This reduction optimizes the equipment's overall volume and weight without compromising on performance, thus enhancing operational efficiency significantly.
(II) Safe and Reliable
- Asbestos - free Friction Material: Utilizing a friction material devoid of asbestos, this design eliminates potential health risks associated with asbestos exposure. It aligns with contemporary environmental and safety standards, offering users a secure and dependable experience.
(III) Easy Maintenance
- Simple Friction Pad Replacement: The friction pads can be replaced effortlessly without the need to dismantle the clutch, drastically reducing maintenance time and costs. This improvement enhances maintenance efficiency and minimizes downtime for your equipment.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: The innovative disc arc design significantly boosts heat dissipation capacity, effectively lowering operational temperatures. This enhancement prolongs the product's service life and ensures stability during prolonged high-load operations.
(V) Quick Response
- Fast Clutching and Braking: With rapid response capabilities, the product delivers swift clutching and braking functions. This meets the fast-paced demands of various mechanical equipment, elevating production efficiency.
(VI) Diverse Connection Methods
- Flexible Connection Options: Offering multiple connection methods, the product adapts flexibly to diverse site requirements, showcasing its versatility and compatibility with a wide range of equipment.


III. Product Structure
The pneumatic clutch brake is composed of the following essential components:
- Clutch Body: Mounted on the equipment's main shaft, the clutch body's center hole size is customizable per customer specifications (refer to sample size range). It stands as the clutch's core element, crucial to its performance.
- Clutch Ear Plate and Brake Ear Plate: Seamlessly connected to the flywheel and machine body of the equipment respectively through four sturdy pins, these components ensure the unwavering stability and smooth operation of the clutch and brake mechanisms.
- Friction Pads (Blocks): These essential components are pivotal in the clutching and braking process, skillfully managing the transmission and interruption of power effectively and efficiently.
- Clutch Pins, Brake Pins, and Locking Plates: Designed for precision, these elements connect and securely fix various components. Locking plates, nestled neatly into the pin grooves, are fastened onto the flywheel or machine body with robust screws to prevent any unwanted axial movement of the pins.


IV. Working Principle
(I) Clutching Process
External compressed air elegantly enters the clutch cylinder via the intake hole, propelling the piston into action. This energy is transferred through the friction pads, clutch body, and flat key, causing the driven part to rotate. This seamless clutch engagement allows for uninterrupted power transmission.

(II) Braking Process
Upon halting the air supply, the piston gracefully shifts in the reverse direction, driven by the spring. Engaging the friction pads, clutch body, and flat key, the driven part is promptly braked. Remarkably, the braking time is a swift 0.01 - 0.02 seconds, ensuring an immediate and efficient stop of the equipment.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Ensure that the hole tolerance for installing the four pins is H7. The hole center must be perfectly parallel to the main shaft center, guaranteeing installation accuracy and unwavering stability of the pins.

(II) Geometric Tolerance and Roughness Requirements
Adhering to stringent national standards, the geometric tolerance and roughness of the center hole and keyway are crucial. Likewise, the customer's main shaft must meet these demanding requirements to significantly enhance product performance.

(III) Installation Sequence Suggestions
Customers have the flexibility to select their preferred installation sequence. Typically, begin with the installation of 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
Square pins are ingeniously designed to compensate for installation size errors of two pins and any thermal deformation of the plate due to clutch heating. Ensure that the two flat surfaces of the square pin are precisely parallel to the radial direction of the ear plate.

(V) Sealing Requirements for Axial Air Intake
For axial air intake configurations, it is paramount to install sealing caps at both ends of the clutch, effectively preventing any gas leakage.

(VI) Check after Installation
Post-installation, verify that the clutch end and brake end move with ease, ensuring the flawless operation of the clutch and brake systems.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every clutch from Shandong Tenord Machinery Equipment Co., Ltd. is rigorously tested to ensure excellence. Customers are advised not to disassemble the clutch on their own, as any damage from such actions will void our responsibility. Encounter any quality issues? Simply notify us promptly, and we will address them efficiently.

(II) Friction Pad Replacement Method
As time moves on and machine usage grows, our friction pads—simple to replace without ear plate or clutch disassembly—may need refreshing. Follow these easy steps to renew your equipment's efficiency without a hitch:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Next, remove the bolts and nuts securing the friction pads, refresh them with new ones, and then securely tighten those bolts and nuts.
- Replacement with Air Supply: Loosen the brake ear plate and adhere to the previous instructions to effectively replace the friction pads.

(III) Timing for Friction Pad Replacement
- For equipment like presses, if the machine's performance dips below its rated capacity, it's time to inspect the friction pads for potential replacement.
- Once the wear surpasses half of the new friction pad's thickness, promptly replace them to maintain optimal function.

VII. Product Selection
Selecting the perfect clutch for your equipment is paramount. Ensure you choose wisely:
- Consequences of Improper Selection: A clutch too small fails to meet rated capacity, whereas an oversized one escalates equipment costs and may lead to overheating, hastening friction pad wear and sealing ring aging.
- Selection Suggestions: Rely on our comprehensive company samples or consult our expert technicians. We are ready to offer tailored professional advice to guide your selection.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
To prevent accidents, never touch the clutch or approach it with objects while it spins at high speeds.

(II) Protection from High Temperature
Avoid direct contact with the clutch immediately after use to prevent burns—wait approximately 30 minutes post-rotation for the temperature to normalize before performing any maintenance.

(III) Side Protection
Standing beside a rotating clutch is dangerous due to potential flying debris. Always ensure a protective cover is in place during operation.

(IV) Attention during Ventilation Operation
During ventilation or air-stopping, refrain from touching the friction pads with your fingers to avoid injury.

(V) Safety of Internal Structure
Our clutches contain internal springs. Unauthorized disassembly can lead to injury; instead, let professionals handle required disassembly safely.
