A magnetic gear is a power transmission device that uses the principles of magnetic attraction and repulsion to transmit torque between rotating components without physical contact. This eliminates the need for physical teeth, making it an alternative to traditional mechanical gears. 
Key Features:
  • Contactless Operation: Unlike mechanical gears, magnetic gears transfer torque through magnetic forces, meaning there is no physical contact between the gears themselves. This offers advantages like reduced friction, wear, and noise.
  • Torque Transmission: By arranging magnets on the gears, a magnetic field is created. As the input gear rotates, its magnetic field interacts with the output gear's magnetic field, causing it to rotate as well, transferring torque.
  • Gear Ratio: Similar to mechanical gears, magnetic gears can provide a specific gear ratio, changing the speed and torque between the input and output shafts. This is achieved by adjusting the number and arrangement of magnets on each gear.
  • Overload Protection: A key advantage of magnetic gears is their inherent overload protection. If the torque exceeds a certain limit, the magnetic coupling can slip, preventing damage to the system.
  • Clean and Quiet Operation: The absence of physical contact also means magnetic gears are quieter and require no lubrication, making them suitable for environments where cleanliness and low noise levels are important. 
In essence, a magnetic gear provides the function of a traditional gear but utilizes magnetic forces for contactless power transmission, resulting in benefits like reduced maintenance, noise, and wear, and inherent overload protection. 

Magnetic Couplings and Gears

  • 1. General Return Policy:

    • Timeframe: You can return stock magnets for a refund within a specified period (e.g., 30 days) from the date of purchase or receipt.
    • Condition: Magnets must be in new and resalable condition, with all original packaging and components. Damaged or used magnets may not be eligible for return.
    • Authorization: You need to obtain a Return Merchandise Authorization (RMA) number before returning any products. 

    2. Exclusions:

    • Custom Orders: Custom-made or marked magnets are generally not eligible for return unless they fail to meet the original specifications.
    • Damaged due to mishandling: Returns may not be accepted for magnets that have been damaged due to improper handling. 

    3. Refunds:

    • Method: Refunds are typically issued to the original payment method.
    • Deductions: Shipping and handling charges are generally non-refundable.
    • Restocking Fees: A restocking fee may apply, especially for items that are not in pristine condition or require reconditioning. 

    4. Faulty or Damaged Products:

    • Defective upon arrival: If you receive a faulty or damaged product due to a manufacturing defect, the supplier may offer a replacement or refund after inspection. 

    5. Process:

    • Contact Customer Service: Contact the supplier to request a return and obtain an RMA number.
    • Securely Package: Package the magnets carefully to prevent damage during return shipping, preferably in the original packaging.
    • Clearly Mark: Ensure the RMA number is clearly marked on the outside of the package. 

  • Basic Shipping Policy

    • Processing Time: Orders are typically processed and shipped within 1-2 business days, excluding weekends and holidays.
    • Shipping Methods: Various shipping options are available, including both domestic and international shipping. FedEx, UPS, and USPS are primarily used.
      • Domestic: Standard ground shipping (e.g., FedEx Ground) and expedited options like 2-Day or Next-Day delivery may be available.
      • International: Shipping for international customers is available using air freight for smaller items and ocean shipping for larger quantities.
    • Shipping Costs: Shipping costs are determined by shipment weight, destination, and shipping method. Costs will be displayed during checkout.
    • Shipping Magnets Safely: Special considerations are taken when shipping magnets to ensure their safe and secure transportation. This may include:
      • Packaging: Magnets are packaged carefully, often with alternating polarities to reduce the magnetic field.
      • Shielding: For powerful magnets, special shielding (like steel-lined boxes) may be used to minimize the magnetic field outside the package, especially for air shipments.
      • Air Shipment Restrictions: Magnets shipped by air must adhere to specific regulations (e.g., FAA and IATA) regarding magnetic field strength at certain distances.
      • Labeling: Packages containing magnets may require special labeling, such as "Magnetized Material," especially for air shipments or if the magnetic field strength exceeds certain limits.
    • International Shipping:
      • Regulations: International shipments, particularly by air, are subject to regulations set by the International Air Transport Association (IATA).
      • Documentation: Proper documentation, including a shipper's declaration for dangerous goods, may be required for air shipments.
      • Prohibited Items: Certain magnets or magnetic materials may be prohibited from air transportation if their magnetic field strength is too high.
    • Delivery Estimates: Estimated delivery times vary depending on the shipping method and destination.
