Long Rare Earth Neodymium Ring Magnet Manufacturers
Product Description
Material: Sintered NdFeB
Size: OD1/4 - ID1/8x1"
Pole Orientation: Axially magnetized
Coating: Ni+Cu+Ni
Grade: N45
Tolerance: +/-0.05mm
Applications: This neodymium magnet ring is perfect for industrial applications and personal applications
This slim ring neodymium magnet measures 1/4" in diameter and 1" in length and features a 1/8" hole through the length of the magnet. It is made of the grade N45 neodymium magnet alloy under ISO 9001 quality control systems, they are plated in a nickel-copper-nickel coating for a shiny corrosion resistant finish.
Electric Motors and Generators: These are the most common applications. The ring rare earth magnets are fixed inside the outer casing (stator) or onto the inner rotor of brushless DC motors and AC synchronous motors.
Magnetic Couplings: Used to transmit torque through a physical barrier without direct contact, creating a hermetic seal.
Magnetic Bearings and Levitation: Provide passive, contact-less support for rotating shafts, reducing friction and wear.
Sensors and Encoders: Used to create a strong, alternating magnetic field that rotary or linear sensors can detect to measure position, speed, and direction.
Warning Tips
Handle with Care: Neodymium magnets are powerful and can chip or shatter if mishandled.
Pacemaker Safety: Keep these magnets at a safe distance from pacemakers and similar medical devices.
Not a Toy: Keep these magnets out of reach of children.
Disposal: Dispose of damaged magnets responsibly to avoid safety hazards.
