(III) Easy Maintenance
- Simple Friction Pad Replacement: The friction pads are designed for easy replacement without disassembling the clutch, significantly cutting down maintenance costs and time, boosting maintenance efficiency, and minimizing equipment downtime.
(IV) Excellent Heat Dissipation Performance
- Unique Disc Arc Design: The innovative disc arc design substantially enhances the product's heat dissipation capacity, effectively lowering operational temperatures, prolonging the product's lifespan, and ensuring equipment stability during prolonged high-load operations.
(V) Quick Response
- Fast Clutching and Braking: With an incredibly fast response time, it swiftly performs clutching and braking functions, catering to various mechanical equipment's demands for quick response, thereby elevating production efficiency.
(VI) Diverse Connection Methods
- Flexible Connection Options: Equipped with a range of connection methods, it allows for adaptable selection tailored to different site requirements, providing robust adaptability and the capacity to seamlessly match diverse equipment.


III. Product Structure
The pneumatic clutch brake is primarily composed of several key components:
- Clutch Body: Securely mounted on the equipment's main shaft, its center hole size is customizable according to client specifications (size range available in the sample), serving as the clutch's core component.
- Clutch Ear Plate and Brake Ear Plate: These critical components are expertly connected to the flywheel and machine body using four precision-engineered pins. This connection ensures the clutch and brake operate with unwavering stability, delivering seamless performance every time.
- Friction Pads (Blocks): These vital elements are at the heart of the clutching and braking process, masterfully enabling both the transmission and interruption of power with exceptional efficiency.
- Clutch Pins, Brake Pins, and Locking Plates: These components are indispensable for connecting and securing various elements. Expertly designed, the locking plates are embedded within pin grooves and fastened to the flywheel or machine body with screws, effectively preventing any axial movement of the pins.


IV. Working Principle
(I) Clutching Process
In the clutching process, external compressed air enters the clutch cylinder via the intake hole, propelling the piston into motion. This action, through the friction pads, clutch body, and flat key, rotates the driven part, achieving clutch engagement and facilitating power transmission.

(II) Braking Process
The braking process is initiated when the air supply ceases, causing the piston to move in reverse under spring action. This motion, through the friction pads, clutch body, and flat key, swiftly brakes the driven part within an astonishing 0.01 - 0.02 seconds, ensuring rapid and efficient equipment stoppage.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
For optimal installation, the hole tolerance for the four pins must adhere to H7 standards, with the hole center precisely parallel to the main shaft center. This precision guarantees the installation accuracy and stability of the pins.

(II) Geometric Tolerance and Roughness Requirements
The geometric tolerance and roughness of both the center hole and keyway must be in strict compliance with national standards. Similarly, the customer's main shaft should adhere to corresponding requirements, enhancing the product's overall performance.

(III) Installation Sequence Suggestions
Customers have the flexibility to determine their installation sequence based on specific circumstances. Typically, the installation of clutch and brake ear plates, pins, and locking plates precedes the installation of the clutch brake body.

(IV) Installation Notes for Square Pins
Square pins are ingeniously designed to mitigate installation size errors between two pins and counteract plate thermal deformation due to clutch heating. Ensure 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 an axial air intake system, it is crucial to install sealing caps at both ends of the clutch to prevent any gas leakage, ensuring airtight performance.

(VI) Check after Installation
Post-installation, it is essential to verify that both the clutch end and brake end move freely, guaranteeing the smooth and efficient operation of the clutch and brake system.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Here at Shandong Tenord Machinery Equipment Co., Ltd., we pride ourselves on delivering clutches of impeccable quality. Each Kb2700 Air Clutch has passed rigorous standards before reaching you. Please refrain from any personal disassembly as this voids any responsibility for mishaps on our part. Experience any hitches? Promptly alert us to ensure swift resolution of any quality issues.

(II) Friction Pad Replacement Method
The friction pads are designed as consumables, with their lifespan tied to the duration and intensity of machine usage. Once wear is evident, prompt replacement is essential. Fortunately, our user-friendly design enables straightforward friction pad replacement, eliminating the need to dismantle ear plates or the clutch. Follow these simplified steps:
- Replacement without Air Supply: Begin by easing the clutch ear plate. Next, detach the bolts and nuts holding the friction pads in place. Swiftly replace them with new ones before re-securing the bolts and nuts tightly.
- Replacement with Air Supply: Gently loosen the brake ear plate and mirror the aforementioned steps to fit new friction pads seamlessly.

(III) Timing for Friction Pad Replacement
- When using equipment like presses, a decline in reaching rated capacity signals the need to evaluate and possibly replace the friction pads.
- It's imperative to replace friction pads when their wear surpasses 50% of a new pad's thickness, safeguarding machine efficiency and longevity.

VII. Product Selection
Choosing the right clutch is paramount to the seamless operation of your equipment. Our commitment extends to assisting in selecting the perfect fit.
- Consequences of Improper Selection: A clutch undersized can't achieve rated capacity, while an oversized one incurs unnecessary costs and risks overheating, prematurely wearing friction pads, and hastening seal ring degradation.
- Selection Suggestions: Trust in our expertise by exploring our comprehensive sample range or consulting with our adept technicians for tailored selection advice.

VIII. Safety Precautions
(I) Protection during High-speed Rotation
Safety is paramount. Under no circumstances should the rotating clutch be touched, whether by hand or object, to prevent hazardous accidents.

(II) Protection from High Temperature
Hands off! After the clutch halts, allow a half-hour period for cooling before any maintenance to avoid burns. Safety first, always.

(III) Side Protection
Never stand in the trajectory of a rotating clutch. Protective covers are a must to guard against errant flying objects. Prioritize your safety.

(IV) Attention during Ventilation Operation
During ventilation or when halting air supply, ensure fingers are well clear of friction pads to prevent accidental pinching.

(V) Safety of Internal Structure
The clutch's internal springs are precisely configured. Disassembly should be strictly undertaken by professionals to prevent injury. Trust our expertise.
