What Are Neodymium Cylinder Magnets
Available Grades and Magnetic Performance
N35
Ideal for general applications: packaging, toys, fixtures, crafts and basic holding use where moderate magnetic force is sufficient.
N42
Suitable for electronics, small motors, sensors, mounting and daily industrial holding with standard requirements.
N45
Designed for applications needing higher force: loudspeakers, magnetic separators, automation components and professional fixtures.
N52
Best for high‑demand applications: precision motors, medical devices, high‑performance sensors and compact designs where strong magnetism is required in limited space.
Key Selection Notes
- Pull strength: increases from N35 to N52
- Temperature resistance: lower grades generally perform more stably under heat
- Cost: rises significantly with higher grades
- Brittleness: higher grades can be more fragile during assembly
- Environment: choose based on working temperature, installation stress and budget
Magnetization Directions
- Poles on the two circular faces
- Most common & cost-effective
- Easy to assemble and standardize
- Typical uses: holding, fastening, sensors, packaging
- Poles on the curved side surface
- Magnetic field across the diameter
- Used in rotors, encoders, small motors, positioning
- Poles radiate from center to outer surface
- For magnetic couplings, drive motors, synchronous rotation
- Requires specialized tooling and higher cost
- Matching magnetization direction avoids assembly failure
- Reduces machining and assembly risks
- Optimizes magnetic efficiency without over-specing
- Supports accurate CAD modeling and prototyping
Standard Sizes and Custom Dimensions
We offer popular standard cylinder neodymium magnets for fast lead times, and full custom solutions for non-standard size requirements.
If none of the above sizes fit your application, please provide your required diameter and length. We support full customization for any dimension, tolerance, grade, coating, and magnetization direction.
