(VI) Diverse Connection Methods
- Flexible Connection Options: It offers a variety of connection methods, allowing for flexible selections based on different site requirements, showcasing strong adaptability and perfect compatibility with diverse equipment.


III. Product Structure
The pneumatic clutch brake is primarily composed of the following components:
- Clutch Body: Mounted on the equipment's main shaft, the central hole size can be tailored to customer specifications (refer to the sample for size range). It serves as the clutch's core component.
- Clutch Ear Plate and Brake Ear Plate: These crucial components are seamlessly connected to the flywheel and machine body of your equipment through four robust pins. This ensures a harmonious and stable operation of both the clutch and brake mechanisms, showcasing reliability in every motion.
- Friction Pads (Blocks): These vital elements are at the heart of the clutching and braking processes, expertly managing the transmission and interruption of power with precision and efficiency, ensuring smooth operational transitions.
- Clutch Pins, Brake Pins and Locking Plates: Integral for secure connectivity and stability, these components are meticulously designed. The locking plates are embedded in the pin grooves and firmly fixed via screws to the flywheel or machine body, effectively preventing any axial movement and maintaining perfect alignment.


IV. Working Principle
(I) Clutching Process
When external compressed air enters the clutch cylinder through the intake hole, it propels the piston forward. This movement, through friction pads, the clutch body, and a flat key, rotates the driven part to achieve clutch engagement, seamlessly transmitting power with remarkable efficiency.

(II) Braking Process
Upon halting the air supply, the piston is driven in the opposite direction by the spring's force. This action, facilitated by the friction pads, clutch body, and flat key, swiftly brakes the driven part. A phenomenal braking time of just 0.01 - 0.02 seconds ensures prompt and efficient stopping, enhancing operational safety.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
The installation of the four pins demands a precise hole tolerance of H7, with the hole center perfectly parallel to the main shaft center. This precision guarantees the impeccable accuracy and stability needed for optimal pin installation.

(II) Geometric Tolerance and Roughness Requirements
The geometric tolerance and roughness for the center hole and keyway are stringently aligned with national standards. It is imperative that the geometric tolerance and roughness of the customer's main shaft adhere to these standards to enhance the product's performance and longevity.

(III) Installation Sequence Suggestions
Customers are encouraged to adapt the installation sequence according to specific scenarios. Generally, it is recommended to first install the clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body, ensuring a streamlined and effective setup.

(IV) Installation Notes for Square Pins
Square pins are ingeniously utilized to counteract any installation size discrepancies between two pins, as well as to address any thermal deformation of the plate caused by clutch heating. It is vital that the two flat surfaces of the square pin remain parallel to the radial direction of the ear plate to maintain structural integrity.

(V) Sealing Requirements for Axial Air Intake
For axial air intake scenarios, it is essential to install sealing caps at both ends of the clutch to effectively prevent any potential gas leakage, thereby ensuring the system's airtight integrity and operational reliability.

(VI) Check after Installation
Post-installation, it is crucial to verify that the clutch end and brake end move freely. This ensures the components are functioning correctly, allowing for the smooth and uninterrupted operation of both the clutch and brake systems.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each clutch sold by Shandong Tenord Machinery Equipment Co., Ltd. has undergone rigorous quality checks. For your safety and to maintain the integrity of your Kb200 Pneumatic Clutch Brake, please refrain from disassembling it privately. Unauthorized disassembly may void any warranties or liabilities on our part. In the event you encounter any quality issues, please alert us promptly, and we are committed to addressing your concerns swiftly and efficiently.

(II) Friction Pad Replacement Method
The friction pads are crucial yet consumable components of your Kb200 Pneumatic Clutch Brake and should be replaced when signs of wear become apparent after extensive use. Fortunately, the replacement process is straightforward and does not require the removal of the ear plates or the clutch itself. Specific replacement methods are as follows:
- Replacement without Air Supply: Begin by loosening the clutch ear plate, then proceed to remove the bolts and nuts that secure the friction pads. Insert new friction pads, ensuring they are correctly placed, and tighten the bolts and nuts securely.
- Replacement with Air Supply: Loosen the brake ear plate and perform the same steps for friction pad replacement, ensuring the new pads are properly secured.

(III) Timing for Friction Pad Replacement
- For equipment such as presses, if the machine struggles to achieve its rated capacity, it is advisable to inspect and potentially replace the friction pads.
- When the wear level of your friction pads surpasses half of their original thickness, it is essential to replace them promptly to maintain optimal performance.

VII. Product Selection
Selecting the right clutch is vital as it serves as a pivotal component of your machinery.
- Consequences of Improper Selection: An undersized clutch may fail to meet your equipment's rated capacity, whereas an oversized clutch can unnecessarily inflate costs and lead to overheating, expedited wear on friction pads, and accelerated aging of sealing rings.
- Selection Suggestions: You are encouraged to reference our comprehensive company samples or reach out to our skilled technicians for expert consultation. We are eager to provide you with tailored, professional selection advice.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
For your safety, avoid any contact with the clutch or inserting objects while it is in high-speed rotation as this can pose serious hazards.

(II) Protection from High Temperature
It is crucial not to touch the clutch with bare hands immediately after it ceases rotation, as residual heat can cause burns. Allow the clutch to cool for approximately half an hour, reaching room temperature before conducting any maintenance.

(III) Side Protection
Do not stand on the side of the clutch while it is spinning to prevent accidents from potential debris. Always use a protective cover for added safety during clutch operation.

(IV) Attention during Ventilation Operation
During the process of ventilating or halting air supply, avoid contacting the friction pads with fingers to prevent any risk of pinching injuries.

(V) Safety of Internal Structure
Our clutches are equipped with internal springs. To prevent injury, do not attempt disassembly unless performed by professionals. Should disassembly be necessary, it is imperative to consult with a qualified technician.
