(VI) Diverse Connection Methods
- Versatile Connection Options: With multiple connection methods available, it offers flexibility to suit various site requirements, showcasing robust adaptability and perfect compatibility with a wide array of equipment.


III. Product Structure
The pneumatic clutch brake is ingeniously crafted from the following key components:
- Clutch Body: Mounted on the primary shaft of the equipment, its center hole size is customizable to meet specific customer requirements (refer to sample for size range), serving as the heart of the clutch mechanism.
- Clutch Ear Plate and Brake Ear Plate: Meticulously connected to the flywheel and machine body of the equipment through four sturdy pins, guaranteeing the unwavering stability and flawless operation of both the clutch and brake mechanisms.
- Friction Pads (Blocks): Serve as the pivotal elements in the intricate clutching and braking processes, enabling seamless transmission and precise interruption of power, ensuring optimal performance at all times.
- Clutch Pins, Brake Pins and Locking Plates: Essential for securing and uniting various components. The locking plates are strategically embedded in pin grooves, firmly secured 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 dynamically enters the clutch cylinder through the intake hole, propelling the piston into motion. Through the combined action of friction pads, clutch body, and flat key, the driven part is set into rotation, achieving clutch engagement and ensuring the seamless transmission of power.

(II) Braking Process
Upon cessation of air supply, the piston is compelled to move oppositely by the force of the spring. This action, via friction pads, clutch body, and flat key, rapidly brakes the driven part. With an astonishing braking time of merely 0.01 - 0.02 seconds, the equipment ensures a swift and efficient stop.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
The hole tolerance for the installation of the four pins must be H7, ensuring that the hole center aligns perfectly parallel with the main shaft center. This precision is crucial for the accurate and stable installation of the pins.

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

(III) Installation Sequence Suggestions
Customers are encouraged to select the installation sequence based on their specific scenarios. Typically, it is advisable to install the clutch and brake ear plates, followed by the pins and locking plates, before proceeding with the clutch brake body installation.

(IV) Installation Notes for Square Pins
Square pins play a crucial role in eliminating the installation size discrepancies between two pins and the plate thermal deformation due to clutch heating. Ensure that the two flat surfaces of the square pin maintain parallelism with the radial direction of the ear plate for optimal performance.

(V) Sealing Requirements for Axial Air Intake
For axial air intake systems, it is imperative to install sealing caps at both ends of the clutch. This precautionary measure effectively prevents any potential gas leakage, safeguarding the integrity of the system.

(VI) Check after Installation
Upon completing installation, ensure that the clutch end and brake end can move without resistance. This verification step is crucial for confirming the smooth and efficient operation of the clutch and brake systems.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Each Kb1200 Pneumatic Clutch offered by Shandong Tenord Machinery Equipment Co., Ltd. is meticulously inspected to ensure premium quality. Customers are advised against unauthorized disassembly, as this can lead to damage for which the company cannot be held accountable. Should you encounter any quality issues, please contact us promptly, and we will address them with utmost priority.

(II) Friction Pad Replacement Method
The friction pads of the Kb1200 Pneumatic Clutch are designed as consumable components and require replacement after extensive use or when noticeably worn. Our friction pad replacement process is straightforward and does not necessitate disassembling either the ear plates or the clutch. The detailed method is as follows:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Proceed to remove the bolts and nuts securing the worn friction pads, replace them with new ones, and ensure a secure fit by tightening the bolts and nuts.
- Replacement with Air Supply: Simply loosen the brake ear plate and follow the same procedure as above to efficiently replace the friction pads.

(III) Timing for Friction Pad Replacement
- For machinery such as presses, when the equipment fails to achieve its rated capacity, it is advisable to assess whether the friction pads are due for replacement.
- When friction pad wear exceeds 50% of their original thickness, it is imperative to replace them promptly to maintain optimal performance.

VII. Product Selection
Choosing the right Kb1200 Pneumatic Clutch for your equipment is of paramount importance to ensure functionality and efficiency.
- Consequences of Improper Selection: Opting for a clutch that is too small results in underperformance, while an excessively large clutch unnecessarily escalates costs and risks overheating, leading to accelerated wear and tear of friction pads and premature seal ring aging.
- Selection Suggestions: Customers are encouraged to refer to our detailed company samples or consult directly with our skilled technicians. We are committed to offering expert advice tailored to your specific needs.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
To prevent potential hazards, avoid any contact with the clutch, whether by hand or with objects, when it is rotating at high speeds.

(II) Protection from High Temperature
To prevent burns, refrain from touching the clutch immediately after it ceases rotation. Allow at least 30 minutes for the unit to cool to ambient temperature before performing any maintenance.

(III) Side Protection
Standing beside a rotating clutch poses risks due to possible debris ejection. Always use a protective cover during operation to enhance safety.

(IV) Attention during Ventilation Operation
During ventilation and air cessation procedures, avoid touching the friction pads with your fingers to prevent injury from pinching.

(V) Safety of Internal Structure
The internal springs of the clutch require professional handling. Unauthorized disassembly is discouraged to avoid injury. Ensure that any necessary disassembly is performed by trained professionals only.
