What is a Stepped Magnets Disc Cylinder NdFeB?

A Stepped Magnets Disc Cylinder NdFeB is a high-performance permanent magnet product with a stepped structural shape design and neodymium iron boron (NdFeB) as its core magnetic material. It integrates the structural characteristics of disc magnets and cylindrical magnets, and through a “stepped terrace structure” achieves precise positioning installation, high magnetic attraction output, and enhanced structural stability. It is widely used in industrial equipment, automation systems, precision machinery, and new energy fields.

Structural definition and shape characteristics

The core structural features of Stepped Magnets Disc Cylinder NdFeBs include: stepped shape design (terrace structure), disc + cylinder combined structure, multi-diameter segmented structure, positioning step structure, precision-machined shape, and central axis symmetry structure.This structure enables automatic positioning during installation, prevents offset and rotation, and improves assembly accuracy and system stability.

Material core: performance advantages of neodymium magnets

Stepped Magnets Disc Cylinder NdFeBs use high-performance NdFeB magnetic material, featuring: high magnetic energy product, strong magnetic force output, high magnetic flux density, small size with strong magnetic force, high power density, and excellent magnetic stability.

Magnetic performance indicators (example ranges):

The stepped structure is not only a shape design but also has functional value: precise embedding into mounting holes, anti-drop structural support, improved assembly stability, enhanced shear resistance, increased structural load-bearing capacity, optimized magnetic circuit distribution, and improved magnetic field concentration.Compared with ordinary cylindrical magnets or disc magnets, the stepped structure has greater advantages in structural stability and magnetic force utilization efficiency.

Typical application scenarios

Stepped Magnets Disc Cylinder NdFeBs are widely used in: servo motor systems, motor rotor assemblies, sensor structures, encoder systems, magnetic positioning systems, automation equipment, industrial robots, new energy vehicle components, precision instrument equipment, and medical device components.

To improve durability, Stepped Magnets Disc Cylinder NdFeBs usually adopt: nickel plating (Ni-Cu-Ni), zinc plating, epoxy resin coating, phosphating treatment, anti-corrosion coatings, and anti-oxidation treatment, to adapt to application requirements in humid, high-temperature, and corrosive environments.

This type of magnet product usually supports: size customization, step height customization, diameter combination customization, magnetic performance grade customization, surface coating customization, and magnetization method customization (axial/radial).

Processing accuracy can reach ±0.02 mm, making it suitable for high-precision assembly systems.

Advantages compared with ordinary disc/cylindrical magnets

Stepped Magnets Disc Cylinder NdFeBs are not only a magnet form, but also a structural engineering magnet solution.Through stepped structural design, they highly integrate magnetic performance output, structural stability, and assembly precision, meeting the comprehensive needs of modern industrial equipment for high-performance magnets: “strong magnetic force + precise positioning + high reliability.”

With the development of high-end equipment manufacturing, new energy vehicles, and intelligent manufacturing, Stepped Magnets Disc Cylinder NdFeBs are gradually moving from “custom magnet products” toward “standardized industrial magnet components,” becoming an important part of high-end magnetic component systems.
