Product Overview
If you need a ring-shaped magnet that delivers both strength and flexibility, our rare earth ring neodymium magnets are made for you. These rings use premium NdFeB material to give you high magnetic force in a hollow form - great for motors, rotary sensors, magnetic couplings, and other applications where a bore or internal diameter is part of the design.
We understand manufacturing needs - you can pick your inner/outer diameters, thickness, coating, and magnetization direction. And when you run production, we've got your back with bulk supply and consistent quality.
Key Specifications
- Material: NdFeB (sintered, rare-earth type)
- Shape: Ring / Hollow disc
- Sizes: Fully customizable - inner diameter, outer diameter, thickness as you need
- Tolerances: ±0.1 mm standard (tighter if needed)
- Coating: Ni-Cu-Ni is standard; other finishing options available (epoxy, zinc, etc.)
- Magnetization Direction: Radial (through thickness), axial, multi-pole, or as per your design
- Working Temperature: up to ~80-100°C (higher-temp grades can be offered)
- Certifications: ISO9001, RoHS, SGS - your quality assurance check
Why These Ring Magnets Matter for B2B Buyers
- Design Compatibility: If your application needs a ring shape (shaft going through, hollow center), these magnets integrate neatly.
- Strong Yet Lightweight: Ring form lets you reduce material while keeping magnetic performance.
- Consistency in Bulk Orders: Dimensional accuracy and magnetic strength are kept tight, batch after batch.
- Durability: Coating and quality process reduce the risk of corrosion or chipping in use.
- Cost-Efficiency: Ordering rings in quantity spreads tooling / production cost, saving per unit cost for you.
Typical Applications
- Rotary motors and generators where ring magnets mount on shafts
- Encoder and sensor rings, magnetic coupling devices
- Magnetic bearings and rotating assemblies
- Magnetic separators or filters where fluid or material passes through center hole
- Speaker designs and audio assemblies that use ring magnets
Ordering & Customization Process
- Tell us your inner / outer diameter and thickness
- Specify magnetization direction (radial, axial, etc.)
- Choose coating & grade suited for your operating environment
- We can send you samples if needed for verification
- Bulk orders go through with full QC, ready for export packaging
Quality & Trust
We test each batch of ring magnets for pull strength, dimensional precision, coating integrity, and magnetic consistency. We log batch details so you can trace material and test results. This is what industrial customers expect, and we make sure you get it.
