Radially Oriented NdFeB Ring Magnets
Radially oriented neodymium iron boron (NdFeB) ring magnets are state-of-the-art ring magnets with diverse magnetization patterns in radial direction. In general, they provide high performance and cost-effective alternatives to arc/segment magnets. According to different production processes, radially oriented NdFeB ring magnets include sintered NdFeB ring magnets, bonded NdFeB ring magnets and hot-pressed NdFeB ring magnets.
single pole radially ring magnet
multi-pole radially ring magnet (straight)
multi-pole radially ring magnet (skew)
Features of Radially Oriented NdFeB Ring Magnets
1. High dimensional accuracy,
2. Optional magnetization patterns including single pole, straight multi-pole and skew multi-pole types,
3. A single ring magnet makes assembly and installation easy and low cost,
4. Simple and stable structure guarantees excellent dynamic balance performance, and
5. Uniform magnetic properties and magnetization waves distribution contribute to low motor noise and smooth torque output.
Although radially oriented NdFeB ring magnets have the above advantages, they need a pressing mold and a magnetizing fixture for production including samples preparation. A set of these custom tools costs 1,000 to 7,000 USD depending on custom magnet’s specifications, so the cost of product development is relatively high in the early stage.
Applications of Radially Oriented NdFeB Ring Magnets
1. Servo motors,
2. Spindle motors,
3. Magnetic couplings,
4. Electrical power steering motors, and
5. DC motors, etc.
I am looking for Radially Oriented Single Pole Magnet.
Please let me know if you have about 48 mm OD and 10 mm thick magnet. magnet . We will use it inside the tube,therefore please provide a strong magnet.
I request you to quote for 10 No.

I need 2 spindle magnetic rings for a mini wood lathe. One of my magnets is broken and won’t allow electrical signal to be sent from the switch to in turn start the spindle. lathe is a 3/4HP variable speed.
Using calipers I determined the ring to be 3mm thick; 6mm wide with an OD of 35mm & ID = 29mm. Is this something you can supply?
Hi Jim,
Thanks for the inquiry. Our sales colleague will contact you soon.

I would like to get a sample pack from you that would have two single pole radial oriented ring magnets one of the magnets needs to fit inside the other and there poles must repel each other in other words the outside diameter of the inner magnet needs to repel the inside diameter of the outer magnet, thanks for your consideration
Good afternoon
I need 8 axial ring magnets and 4 radial ring single pole magnets If possible in N52 if not, please inform me the options. Dimensions must be 40 OD / 20 ID / 8 t. thanks for your informations and help.
Good afternoon,
We are in need of permanent magnets with the following specs.
Axiall B field=0.5T with less than 2% variation over a length of 80mm
The magnet should have ID greater 100mm and OD should be about 250mm.
Please send us the quotation and design at the following email id:
I need a single pole radial neodymium ring magnet with an ID of 127mm and an OD of 177.8mm and a thickness of 20mm, I would like it to be nickle platted. I also need it to be strong.
Hi Matthew, this ring magnet D177.8xD127x20mm needs a custom mold. For one custom radial ring magnet only, its cost is too high, it is not recommended. We have an available size of single pole radial neodymium ring magnet, D70xD58x30mm, N40H grade, nickel plated. If you need this, do not hesitate to contact us.
