(III) Easy Maintenance
- Hassle-Free Friction Pad Replacement: The straightforward process of replacing friction pads without disassembling the clutch significantly cuts down maintenance costs and time, boosting maintenance efficiency and minimizing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Innovative Disc Arc Design: Our unique disc arc design enhances the product's heat dissipation capabilities, drastically reducing operational temperatures. This not only extends the product's lifespan but also ensures consistent equipment stability during prolonged, high-load operations.
(V) Quick Response
- Rapid Clutch and Brake Functions: Possessing swift response capabilities, it efficiently executes clutching and braking actions, catering to various mechanical equipment's need for quick responsiveness, thereby elevating production efficiency.
(VI) Diverse Connection Methods
- Adaptable Connection Options: Featuring multiple connection methods, it offers flexible selections tailored to diverse site requirements, providing robust adaptability and seamless compatibility with an array 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 center hole size can be customized as per client needs (refer to sample for size range), serving as the clutch's pivotal component.
- Clutch Ear Plate and Brake Ear Plate: These vital components connect the flywheel and machine body securely via four robust pins, ensuring smooth and stable operation of both the clutch and the brake system, vital for optimal performance.
- Friction Pads (Blocks): Serving as the cornerstone in the clutching and braking operations, these critical elements facilitate seamless power transmission and interruption, essential for efficient machine functionality.
- Clutch Pins, Brake Pins and Locking Plates: These indispensable connectors and fixers are crucial for the stability and rigidity of various components. The locking plates nestle into pin grooves and are fastened onto the flywheel or machine body to steadfastly prevent axial pin movement.


IV. Working Principle
(I) Clutching Process
Upon introduction of external compressed air into the clutch cylinder via the intake hole, the piston is actuated, thrusting into motion. This action, through friction pads, clutch body, and flat key, prompts the driven part to rotate, achieving clutch engagement and enabling flawless power transmission.

(II) Braking Process
Ceasing the air supply activates a spring-induced piston movement in the opposite direction. This motion, via friction pads, clutch body, and flat key, expedites the braking of the driven part within an impressive 0.01 - 0.02 seconds, enabling rapid equipment cessation with unparalleled precision.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Precision is key: the hole tolerance for the four-pin installation should be H7, with the hole center perfectly parallel to the main shaft center. This precision guarantees the accuracy and stability required for optimal pin installation and system integrity.

(II) Geometric Tolerance and Roughness Requirements
Stringent adherence to national standards for geometric tolerance and roughness of the center hole and keyway is paramount. Additionally, ensuring the customer's main shaft meets corresponding criteria significantly enhances product performance.

(III) Installation Sequence Suggestions
Flexibility meets efficiency: customers can tailor the installation sequence to suit specific needs. Typically, commence with the installation of clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body, to ensure seamless assembly.

(IV) Installation Notes for Square Pins
Square pins play a pivotal role in offsetting installation size discrepancies of two pins and mitigating plate thermal deformation due to clutch heating. It is crucial that the two flat surfaces of the square pin align parallel to the ear plate's radial direction.

(V) Sealing Requirements for Axial Air Intake
For axial air intake systems, the installation of sealing caps at both ends of the clutch is essential to prevent any gas leakage, preserving system integrity and performance.

(VI) Check after Installation
Post-installation diligence: ensure that the clutch end and brake end move without constraint, a critical check to verify the normal functioning and reliability of the clutch and brake system.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every Kb2000 Pneumatic Brake, crafted by Shandong Tenord Machinery Equipment Co., Ltd., has passed stringent quality checks. Customers are advised not to dismantle the clutch on their own. Should any damage result from unauthorized disassembly, the company holds no liability. Promptly notify us of any quality issues, and our team will address them swiftly.

(II) Friction Pad Replacement Method
Our friction pads, while durable, are consumable components. After extended use, replace them when significantly worn. The procedure for replacing our friction pads is straightforward, requiring no removal of the ear plates or clutch. Follow these detailed steps to ensure seamless replacement:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Remove the bolts and nuts securing the worn friction pads, replace them with new ones, and securely tighten the bolts and nuts.
- Replacement with Air Supply: Loosen the brake ear plate and repeat the above procedure for a hassle-free swap with new friction pads.

(III) Timing for Friction Pad Replacement
- For machinery such as presses, assess the machine's capacity. If it falls short of the rated output, inspect the friction pads for potential replacement needs.
- When friction pad wear surpasses 50% of their original state, it is critical to replace them promptly.

VII. Product Selection
Selecting the right clutch for your equipment is essential to ensure optimal functionality.
- Consequences of Improper Selection: A clutch that's too small won't achieve rated capacity; an oversized clutch elevates costs, risks overheating, accelerates friction pad wear, and hastens sealing ring aging.
- Selection Suggestions: Choose confidently by consulting our comprehensive samples or contacting our technical experts. We offer expert guidance to ensure the ideal choice.

VIII. Safety Precautions
(I) Protection during High-Speed Rotation
Never touch the clutch with hands or any object while it rotates at high speed to prevent hazardous situations.

(II) Protection from High Temperature
Avoid direct contact with the clutch immediately post-rotation to prevent burns. Allow approximately half an hour for the clutch to cool to ambient temperature before commencing maintenance.

(III) Side Protection
Standing by the side of a rotating clutch is prohibited to avert accidents from ejected objects. Always ensure a protective cover is in place during operation.

(IV) Attention during Ventilation Operation
During air supply and stoppage transitions, do not touch the friction pads with fingers to avoid being caught.

(V) Safety of Internal Structure
The clutch contains internal springs. Unauthorized disassembly is dangerous and should be avoided. Only qualified professionals should perform any necessary disassembly.
