(III) Easy Maintenance
- Effortless Friction Pad Replacement: The friction pads can be easily replaced without disassembling the clutch, significantly reducing maintenance costs and downtime, while boosting equipment maintenance efficiency.
(IV) Excellent Heat Dissipation Performance
- Ingenious Disc Arc Design: This design substantially enhances the product's heat dissipation capabilities, effectively lowering operational temperatures, prolonging product lifespan, and ensuring equipment stability during prolonged high-load operations.
(V) Quick Response
- Rapid Clutching and Braking: Boasting an impressive response time, it swiftly executes clutching and braking functions, catering to the demand for quick responses in various mechanical equipment, thereby elevating production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Equipped with multiple connection methods, it offers adaptability and perfect compatibility with a variety of equipment based on different site requirements.


III. Product Structure
The pneumatic clutch brake comprises the following key components:
- Clutch Body: This is mounted on the main shaft of the equipment, with a customizable center hole size to meet customer specifications (refer to the sample for size range), serving as the core component of the clutch.
- Clutch Ear Plate and Brake Ear Plate: Meticulously engineered for precision, these components attach to the flywheel and machine body via four robust pins, guaranteeing unwavering clutch and brake performance.
- Friction Pads (Blocks): Essential for seamless clutching and braking, these pads facilitate the smooth transmission and interruption of power, enhancing operational efficiency.
- Clutch Pins, Brake Pins, and Locking Plates: Expertly crafted to secure various components, with locking plates strategically embedded in pin grooves and affixed to the flywheel or machine body, ensuring axial stability.


IV. Working Principle
(I) Clutching Process
External compressed air flows into the clutch cylinder through the intake hole, activating the piston. This, in turn, engages the friction pads, clutch body, and flat key, enabling rotation of the driven part for flawless power transmission.

(II) Braking Process
Upon cessation of air supply, the piston retracts via spring action, engaging the friction pads, clutch body, and flat key for swift braking. This rapid response halts operations within 0.01 to 0.02 seconds, ensuring prompt stoppage.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Ensure hole tolerance at H7, with the hole center aligned parallel to the main shaft center for optimal pin installation accuracy and stability.

(II) Geometric Tolerance and Roughness Requirements
Geometric tolerance and roughness of central holes and keyways must adhere to national standards. The main shaft's precision alignment is crucial for enhanced product performance.

(III) Installation Sequence Suggestions
Choose your installation sequence wisely. Typically, begin with clutch and brake ear plates, pins, and locking plates, followed by the clutch brake body for streamlined assembly.

(IV) Installation Notes for Square Pins
Square pins are designed to counteract installation size discrepancies and thermal deformation due to clutch heat. Ensure their flat surfaces remain perpendicular to the ear plate's radial direction.

(V) Sealing Requirements for Axial Air Intake
For axial air intake systems, install sealing caps at both ends of the clutch to prevent gas escape and maintain system integrity.

(VI) Check after Installation
Post-installation, confirm that the clutch and brake ends move unimpeded, safeguarding the clutch and brake's reliable operation.

VI. Product Maintenance - Ensuring peak performance
(I) Expert Maintenance Recommendations
At Shandong Tenord Machinery Equipment Co., Ltd., each Kb1000 Pneumatic Clutch Brake is meticulously inspected before delivery. To ensure continued excellence and functionality, customers must refrain from unauthorized disassembly as it may lead to damage, for which we cannot be liable. In the unlikely event that you encounter any quality issues, please notify us promptly. We are committed to resolving any matters with utmost urgency and efficiency.

(II) Seamless Friction Pad Replacement Method
The friction pads in our Kb1000 Pneumatic Clutch Brake are vital consumable components. Over time and extensive use, replacement becomes necessary when signs of significant wear appear. Fortunately, replacing the friction pads is a hassle-free process that requires no disassembly of the ear plates or the clutch itself. Follow the detailed guidelines below for a smooth replacement experience:
- Replacement without Air Supply: Begin by loosening the clutch ear plate. Remove the bolts and nuts securing the friction pads. Swap in new friction pads, ensuring a snug fit, and then securely tighten the bolts and nuts.
- Replacement with Air Supply: Loosen the brake ear plate and follow the aforementioned steps to efficiently replace the friction pads.

(III) Optimal Timing for Friction Pad Replacement
- For machinery such as presses, if the equipment falls short of its rated capacity, inspect the friction pads for potential replacement.
- Should the wear of the friction pads exceed half their original thickness, it is crucial for customers to proceed with a timely replacement to maintain operational integrity.

VII. Product Selection - Making the Right Choice
Choosing the correct clutch for your equipment is essential for operational efficiency and durability.
- Consequences of Improper Selection: A clutch that is too small won't fulfill the rated capacity, while an oversized one not only raises equipment costs but also risks overheating. This can accelerate the wear of friction pads and hasten the deterioration of sealing rings.
- Selection Suggestions: For the best results, customers are encouraged to refer to our company's catalogs or consult directly with our expert technicians. We are ready to offer professional advice and tailored solutions to meet your specific needs.

VIII. Safety Precautions - Prioritizing Protection
(I) Safeguards during High-speed Operation
Under no circumstances should the clutch be touched by hands or objects while rotating at high speeds, as this poses significant danger.

(II) High Temperature Caution
Direct contact with the clutch just after it ceases rotation must be avoided to prevent burns. Allow approximately thirty minutes for the clutch to cool to a safe, ambient temperature before any maintenance activities.

(III) Lateral Safety Measures
Standing beside a rotating clutch is hazardous due to the risk of flying debris. Employing a protective cover around the clutch is recommended during operation.

(IV) Precautions during Ventilation Processes
Avoid finger contact with the friction pads during ventilation or air-stop operations to prevent injury from pinching.

(V) Internal Structure Safety
Our clutch contains internal springs and should not be disassembled without professional expertise due to the risk of injury. Disassembly should only be undertaken by qualified personnel.
