The problem this part solves
A ring is not a disc with a hole guessed later. ID, OD, thickness and pole pattern have to be set before pressing.
Where it is used
- Magnetic couplings
- Speakers and acoustics
- Rotary sensors
- Motor and pump assemblies
How to inquire
Send quantity, grade, coating, magnetization direction and a drawing or marked photo. If you are matching a sample, include the measured diameter or block size. Custom lots are quoted against the 10–15 day window published on the original product pages. N35 stock sizes, when available, ship sooner.
Questions buyers actually ask
Can you magnetize multipole?
Yes. Multipole rings need a custom fixture and extra lead time. Say how many poles and which face.
Bonded or sintered?
This page is sintered NdFeB. Bonded rings are a different process — ask if you need complex net shapes.
