(I) Application Fields
Our product is extensively utilized in sectors like forging, printing, textile, welding, and shipbuilding, earning accolades particularly in metal processing, paper machinery, woodworking, and fiber machinery industries.

II. Product Advantages
(I) Compact Structure
- Featuring a Small Axial Size and Lightweight Design: The compact axial dimensions and reduced weight, alongside minimal inherent rotational inertia, significantly diminish the equipment's overall size and weight, while ensuring optimal performance, thereby enhancing operational efficiency.
(II) Safe and Reliable
- Asbestos-Free Friction Material: Employing friction material devoid of asbestos components, mitigating any health risks associated with asbestos, while complying with contemporary environmental and safety standards to deliver a safer, more dependable user experience.
(III) Easy Maintenance
- Simplified Friction Pad Replacement: With an easy friction pad replacement procedure that doesn't necessitate clutch disassembly, maintenance costs and downtime are greatly reduced, enhancing equipment maintenance efficacy and minimizing operational interruptions.
(IV) Excellent Heat Dissipation Performance
- Ingenious Disc Arc Design: This distinctive disc arc design markedly boosts the product's heat dissipation capabilities, effectively controlling operational temperatures, extending product longevity, and securing the equipment's stability during prolonged high-load conditions.
(V) Quick Response
- Swift Clutching and Braking: This product offers rapid response capabilities, swiftly executing clutching and braking actions, addressing the diverse mechanical equipment demands for quick reactions, thereby enhancing production efficiency.
(VI) Diverse Connection Methods
- Versatile Connection Options: Furnished with multiple connection alternatives, it provides flexible adaptation to varied site requirements, demonstrating robust adaptability and perfect compatibility with diverse equipment.


III. Product Structure
The pneumatic clutch brake comprises the following essential components:
- Clutch Body: Mounted on the equipment's main shaft, with a customizable center hole size to meet customer specifications (refer to the sample for size range), and serving as the clutch's pivotal component.
- Clutch Ear Plate and Brake Ear Plate: Expertly attached to the flywheel and machine body with four robust pins, these components ensure the seamless and stable operation of both the clutch and brake systems, guaranteeing reliability.
- Friction Pads (Blocks): These essential elements play a pivotal role in the engagement and disengagement process, skillfully managing the transmission and interruption of power with precision.
- Clutch Pins, Brake Pins, and Locking Plates: Ingeniously designed for secure connection and fixation of various parts. The locking plates are meticulously embedded in pin grooves and firmly secured to the flywheel or machine body with screws, effectively preventing axial movement of the pins.


IV. Working Principle
(I) Clutching Process
External compressed air is introduced into the clutch cylinder via the intake hole, propelling the piston into motion. Through the ingenious design of the friction pads, clutch body, and flat key, the driven component is set into rotation, facilitating seamless clutch engagement and power transmission.

(II) Braking Process
Upon cessation of the air supply, the piston is compelled to move inversely by the spring's force, and through the friction pads, clutch body, and flat key, the driven part is swiftly braked. The braking response is exceptionally rapid, taking only 0.01 - 0.02 seconds, ensuring the equipment halts promptly and effectively.

V. Installation Requirements
(I) Hole Diameter and Parallelism Requirements
Install precision is paramount, with the hole tolerance for the four pins specified at H7, and parallelism of the hole center to the main shaft center is crucial for ensuring the stability and accuracy of pin installation.

(II) Geometric Tolerance and Roughness Requirements
Strict adherence to national standards for geometric tolerance and roughness is mandatory for the center hole and keyway. The customer's main shaft must also meet these crucial specifications to enhance product performance.

(III) Installation Sequence Suggestions
Flexibility in installation sequence allows adaptation to different scenarios. Generally, it is recommended to first install the clutch and brake ear plates, pins, and locking plates, before proceeding with the clutch brake body for optimal setup.

(IV) Installation Notes for Square Pins
Square pins are specifically employed to correct installation size discrepancies of two pins and counteract plate deformation from clutch heating. Ensure that the two flat surfaces of the square pin remain parallel to the radial direction of the ear plate for optimal performance.

(V) Sealing Requirements for Axial Air Intake
For axial air intake systems, it is crucial to affix sealing caps at both ends of the clutch to effectively prevent any gas leakage, ensuring smooth operation.

(VI) Check after Installation
Upon completing installation, verify that the clutch end and brake end move with ease, confirming the normal and efficient operation of the clutch and brake systems.

VI. Product Maintenance
(I) Professional Maintenance Suggestions
Every clutch marketed by Shandong Tenord Machinery Equipment Co., Ltd. undergoes meticulous quality checks. Customers are advised against unauthorized disassembly of the clutch. Any damage from such disassembly will void our responsibility. Kindly report any quality issues promptly, and we pledge swift resolution.

(II) Friction Pad Replacement Method
As integral consumables, the friction pads of our Versatile Clutch Brake Punching Machine should be replaced when extensively used and visibly worn. Our friction pad replacement process is streamlined, requiring no removal of the ear plates or clutch. Here's how it's done:
- Replacement without Air Supply: Simply loosen the clutch ear plate, remove the bolts and nuts securing the pads, replace with new ones, and firmly tighten the bolts and nuts back in place.
- Replacement with Air Supply: Loosen the brake ear plate, mirror the above steps, and install new friction pads efficiently.

(III) Timing for Friction Pad Replacement
- On machinery like presses, if the equipment fails to achieve rated capacity, inspect the friction pads promptly for replacement necessity.
- Should the friction pad wear exceed half of their original thickness, it's imperative to replace them without delay.

VII. Product Selection
Selecting the correct clutch is paramount for optimal functionality and performance of your equipment.
- Consequences of Improper Selection: An undersized clutch won't meet capacity needs, while an oversized one escalates costs and risks overheating, causing premature wear and seal ring degradation.
- Selection Suggestions: Our comprehensive samples are available to aid your decision, or consult our knowledgeable technicians for expert guidance tailored to your needs.

VIII. Safety Precautions
(I) Protection during High-Speed Rotation
To ensure safety, refrain from contacting the clutch or approaching with objects while it is spinning at high velocity.

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

(III) Side Protection
For your safety, never position yourself beside the rotating clutch. To protect against potential hazards, a safety cover is strongly recommended during use.

(IV) Attention during Ventilation Operation
During ventilation or air-stopping procedures, avoid finger contact with friction pads to prevent injury.

(V) Safety of Internal Structure
The clutch contains internal springs; do not attempt unauthorized disassembly to avoid potential harm. Professional handling is required for any disassembly.
