Osenc는 소형 원형 형상에서 신뢰할 수 있는 유지력이 필요한 엔지니어, 구매 담당자 및 제작자를 위해 네오디뮴 디스크 자석을 공급합니다.
N35~N56 등급과 다양한 코팅, 축 방향 또는 직경 방향 착자를 선택할 수 있으며 양산 전 샘플을 지원합니다.
네오디뮴 디스크 자석을 선정할 때 자석 등급은 출발점일 뿐입니다. 엔지니어링 용도에서는 최대 에너지적(BHmax), 잔류 자속 밀도(Br), 보자력(Hcj), 사용 온도 및 필요한 착자 방향이 핵심 값입니다.

*Pull force values are reference estimates under ideal test conditions (clean, flat steel, direct contact, straight pull). Real holding depends on steel type, surface condition, air gaps, coatings, and alignment.
Pull force is a useful comparison number—but it’s not a promise in every assembly. The same magnet can behave very differently depending on the magnetic circuit and mounting surface.
What reduces holding in real use:
Air gaps (paint, tape, coatings, uneven surfaces).
Rough or thin steel, small contact area, misalignment.
Side loads/shear loads vs straight pull.
Rust, debris, and repeated impacts.
Practical rule: For critical holds, design with a safety factor and test the magnet in your actual setup.
Sensors, rotating assemblies, or when you need the strongest field across the diameter rather than thickness.

Osenc offers multiple coatings so your disc magnets match real environments—not just lab conditions.
Up next: sizes & tolerances—because fit matters as much as force in many builds.”
Disc magnets are typically specified by diameter × thickness. Standard tolerance works for most holding and closure uses. For alignment, sensing, or assemblies with press fits, tighter tolerances reduce rework and improve consistency.
What to send for accurate quoting:
Most standard NdFeB disc magnets are suited for typical ambient conditions. If your assembly sees elevated heat, confirm operating temperature early—temperature affects magnetic performance and long-term stability.
팁: Tell us your max operating temperature and duty cycle, and we’ll recommend a suitable material option.
Now let’s make selection easier with real-world use cases by industry.
Neodymium disc magnets are used when a compact round magnet needs to deliver strong holding, sensing, or alignment force in limited space.
The adhesive magnet has double-sided tape on its back. You can stick those magnets to a variety of surfaces. And there can be different types of double-sided tapes, which are designed for various applications.
Next: why Osenc—quality checks, traceability, and how we reduce procurement risk.
Written by Ben (Osenc) — focused on selection guidance for neodymium disc magnets used in industrial and commercial builds.
Specs are confirmed during quoting (size, grade, coating, magnetisation, tolerance). For critical loads, we recommend application testing and appropriate safety factors.
“Next: packaging & shipping—how we prevent chipping and unwanted attraction in transit.”
Neodymium disc magnets can chip and attract unexpectedly if packed poorly. We package to reduce collision, protect coatings, and keep parts separated for safer handling.

예. Osenc는 최대 N56 등급. 의 디스크 자석을 공급할 수 있습니다. 공급 가능 여부와 리드 타임 확인을 위해 치수(D×T), 코팅 및 수량을 알려 주십시오.
에폭시 또는 플라스틱 코팅은 습기에 노출되는 환경에서 일반적으로 선택되며, Parylene은 정밀 제작에서 얇고 균일한 보호가 필요한 경우 선택할 수 있습니다.
축 방향 착자의 자극은 평면에, 직경 방향 착자의 자극은 측면에 형성됩니다. 적합한 방식은 필요한 자기장 방향에 따라 달라집니다.
예. 도면 또는 목표 치수, 자석 등급, 코팅, 공차 및 수량을 보내주십시오.
