Round With Straight Hole Ring Standard N35 Strong NdFeB Magnets

N35 Neodymium Ring Magnet - Straight‑Hole Design for Industrial‑Grade Assemblies

Our neodymium ring magnet in Grade N35 features a straight‑through hole and is optimized for manufacturing and engineering applications. Built from high‑grade NdFeB material and finished with a durable Ni‑Cu‑Ni layer, this ring magnet offers dependable performance in assemblies demanding consistent magnetic force and fit‑up precision.

 

 

• Material: NdFeB (Neodymium‑Iron‑Boron)
• Grade: N35 (or higher on request) 
• Shape: Ring (round with straight hole)
• Dimensions: Outer Diameter × Inner Diameter × Thickness - customizable to project needs 
• Tolerance: ± 0.1 mm standard 
• Coating: Nickel plated (Ni–Cu–Ni) for corrosion resistance 
• Magnetization direction: Axial (parallel to height) 
• Working temperature: Up to ~80 °C 
• Certifications: ISO9001, TS16949, RoHS, SGS available

• Precision fit for assemblies: The straight‑hole design simplifies mechanical mounting, ideal for devices where a fastener or shaft must pass through the magnet.
• Tailored sizing for OEM runs: As a trusted rare‑earth ring magnet supplier, we offer custom OD/ID/thickness configurations so you can drop the part directly into your tooling without major modification.
• Reliable production scale: Whether you're ordering a few hundred units for prototype or thousands for series production, we support bulk N35 neodymium ring magnets with consistent quality and documentation.
• Robust finish for harsh environments: The Ni–Cu–Ni coating adds corrosion resistance and aesthetic consistency, suitable for automotive, electronics, and industrial equipment applications.

 

 

• Electric motors and generators where ring geometry with internal shaft is required.
• Magnetic couplings and bearings using ring magnets for torque transfer.
• Sensor mounts, loudspeaker drivers and precision assemblies leveraging the ring hole for alignment.
• Industrial fixtures, mounting hubs or rotating assemblies where space and magnetic force both matter.

1. Send your required outer diameter, inner diameter, thickness, grade, coating and quantity.
2. Receive a sample part for evaluation-fit, pull strength, coating inspection, magnetization direction.
3. Upon approval, we can run a pilot production run and provide inspection summary.
4. Full‑scale order processed with batch testing, shipping documentation, and lead times aligned with your production schedule.

Every lot is inspected for dimensional accuracy, coating integrity, and magnetic performance such as pull force and flux density. We provide certification as required to meet OEM audit or supplier qualification standards.
