Professional Permanent Magnetic Couplings for Motor and Pump Applications
Custom Halbach Array Magnetic Couplings with High Torque Transmission
Engineered permanent magnetic couplings featuring Halbach array magnetic circuit design and high-performance magnets, delivering reliable torque transmission and leak-free operation for motor pump and industrial applications.
Product Overview
Permanent magnetic couplings are advanced non-contact power transmission devices designed for applications requiring reliable sealing, anti-vibration, and low-noise operation. Constructed with ferrite neodymium or samarium cobalt magnets arranged in Halbach arrays, they provide high flux density up to 1.4T and residual induction ≥1.2T. With customizable pull force and nickel plating surface treatment, these couplings offer stable performance across a wide operating temperature range from 80°C to 350°C.

Frequently Asked Questions
Order Information Requirements
We will help you with your order. Usually we ask for the following information:
- Product material, size, grade, surface coating, quantities required. If available, provide a sketch or drawing with dimensions and tolerances
- Delivered magnetized or unmagnetized? Magnetization direction?
- Information on intended application and usage
Can you do OEM and ODM?
OEM and ODM are acceptable. Please inform us of your requirements for reference.
What about the sample lead time and charge?
For OEM or ODM projects, it typically takes 1-2 weeks to calculate charges. For available or in-stock items, samples are shipped within 5-10 days. Final charges depend on your confirmation of the project draft.
How can I place an order?
You can contact us by email with your order details or place orders online.
What's the order procedure?
First, we discuss order and production details via email. Then we issue a Proforma Invoice for your confirmation. Full payment or deposit is required before production begins. Production typically takes 15-25 days for non-stock items. Before completion, we coordinate shipment details and balance payment. After payment settlement, we prepare your shipment.
How can I pay you?
After confirming our PI, we request payment via T/T (HSBC bank), PayPal, or Western Union. L/C, D/A, and D/P are also available.
Can we visit your factory?
Factory visits are highly appreciated. We will send an invitation once your schedule is confirmed.
