Precision Sintered Tube NdFeB Magnets
Industrial-grade Rare Earth Tube Neodymium Magnets for precise magnetic circuits and high-efficiency motor applications.
Engineered for Dimensional Perfection
Our Tube NdFeB Magnets (also known as ring or hollow cylindrical magnets) provide a concentrated magnetic field within a streamlined profile, ideal for high-tech sensors and linear actuators.
Superior Magnetic Grade
Available from N35 to N52,M,H,SH,UH. Our sintering process ensures high remanence (Br) and excellent coercive force (Hcj).
Extreme Precision
Outer and inner diameter tolerances as tight as ±0.05mm, essential for high-speed rotors and magnetic couplings.
Tailored Magnetization
Choose from Axial, Diametrical, or Multi-pole magnetization to suit your specific magnetic circuit design.
Reliability for Demanding Environments
From magnetic fluid treatment to high-performance BLDC motors, our tube magnets are built to last.
