(VI) Diverse Connection Methods
- Versatile Connection Options: It offers a variety of connection methods, adaptable to different site requirements, providing robust compatibility and a perfect match for a wide array of equipment.


III. Product Structure
The pneumatic clutch brake is primarily composed of the following components:
- Clutch Body: Mounted on the equipment's main shaft, with a customizable center hole size (refer to the sample for size range), serving as the clutch's pivotal component.
- Clutch Ear Plate and Brake Ear Plate: These crucial components are seamlessly connected to the flywheel and the machine body through the precision of four pins. This configuration ensures that the clutch and brake operate with unparalleled stability and reliability during every use.
- Friction Pads (Blocks): These essential elements are at the heart of the clutch and braking mechanism. They are pivotal in enabling the smooth transmission and precise interruption of power, providing seamless transitions during operations.
- Clutch Pins, Brake Pins, and Locking Plates: These components are indispensable in the secure connection and stabilization of various parts. The locking plates are meticulously embedded within pin grooves and fixed onto the flywheel or machine body with screws, effectively preventing any undesirable axial movement of the pins.


IV. Working Principle
(I) Clutching Process
When external compressed air flows into the clutch cylinder via the intake hole, it propels the piston into action. Through the dynamic interaction of friction pads, the clutch body, and flat key, the driven component rotates seamlessly, activating clutch engagement for efficient power transmission.

(II) Braking Process
Upon halting the air supply, the spring's force drives the piston in the reverse direction. This results in the friction pads, clutch body, and flat key initiating a swift braking action on the driven component, achieving a rapid stop in as little as 0.01 to 0.02 seconds, ensuring immediate cessation and safety.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
To ensure precision and stability, the hole tolerance for the installation of the four pins should conform to H7 standards. Additionally, the alignment of the hole center must be parallel to the main shaft center, which is crucial for maintaining the accuracy and stability of the installation.

(II) Geometric Tolerance and Roughness Requirements
Both the geometric tolerance and surface roughness of the center hole and keyway are required to strictly adhere to national standards. In parallel, the main shaft's geometric tolerance and roughness must also meet specified criteria to enhance the overall performance of the product.

(III) Installation Sequence Suggestions
Customers have the flexibility to adapt the installation sequence based on specific circumstances. Typically, it is advisable to begin with the clutch and brake ear plates, followed by the pins and locking plates, and finally proceed with the installation of the clutch brake body for optimal results.

(IV) Installation Notes for Square Pins
Square pins play a vital role in compensating for any installation size discrepancies between two pins and counteracting plate thermal deformation caused by clutch heating. It is crucial to ensure that the two flat surfaces of the square pin remain parallel to the radial direction of the ear plate.

(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 to effectively prevent any gas leakage, thereby maintaining the integrity of the system.

(VI) Check after Installation
A thorough check post-installation is essential. Both the clutch end and brake end must move without any hindrance, ensuring that the clutch and brake function smoothly and efficiently, safeguarding the equipment's performance.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every Kb3000 Pneumatic Clutch by Shandong Tenord Machinery Equipment Co., Ltd. has undergone rigorous quality checks. Customers must refrain from unauthorized disassembly, as this voids any liability on our part for resulting damages. Should any quality issue arise, promptly notify us so we can ensure a swift resolution.

(II) Friction Pad Replacement Method
Our friction pads, integral to the product, wear over time and require replacement for optimal performance. The ease of replacement is a hallmark of our design, eliminating the need to disassemble ear plates or the clutch. Below is the streamlined method:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Then, remove the bolts and nuts securing the worn-out friction pads, replace them with new ones, and proceed to tighten the bolts and nuts securely.
- Replacement with Air Supply: Simply loosen the brake ear plate and follow the aforementioned steps for a seamless new friction pad installation.

(III) Timing for Friction Pad Replacement
- For press and similar equipment, should the machine fail to achieve its rated capacity, evaluate whether the friction pads require replacement.
- When friction pads exhibit wear beyond half their original thickness, timely replacement is crucial to maintain performance.

VII. Product Selection
Selecting the right clutch is vital for the functionality of your equipment. Ensuring compatibility safeguards operation and efficiency.
- Consequences of Improper Selection: An undersized clutch fails to meet capacity, while an oversized one escalates costs and risks overheating, hastening wear on friction pads and seal ring aging.
- Selection Suggestions: Refer to our extensive product samples or consult our technical experts. We offer tailored advice for the ideal clutch choice tailored to your needs.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
Avoid contact with the clutch or objects when it is operating at high speeds to prevent injuries.

(II) Protection from High Temperature
Refrain from direct hand contact with the clutch immediately post-operation to prevent burns. Allow approximately 30 minutes for the clutch to cool to a safe temperature before maintenance.

(III) Side Protection
Standing beside the rotating clutch poses risks from airborne debris. Always ensure a protective cover is installed during operation.

(IV) Attention during Ventilation Operation
During air ventilation or shutdown, strictly avoid placing fingers on friction pads to prevent pinching injuries.

(V) Safety of Internal Structure
With internal springs present, the clutch should not be disassembled without professional expertise to avoid injury. Professional handling is required for any disassembly.
