Neodymium Cup Magnets
Description
Reviews
As a leading NdFeB pot magnet manufacturer in China, MAG SPRING offers high-performance Neodymium Cup Magnets (also known as Neodymium Cup Holding Magnets or Countersunk Pot Magnets). These powerful mounting magnets consist of a strong rare earth NdFeB magnet encased in a steel cup, providing exceptional holding force for secure mounting, lifting, fixing, and positioning in various industrial and commercial applications.
Product Overview
Neodymium Cup Magnets are composed of a high-performance sintered NdFeB magnet housed in a durable steel cup. The steel casing concentrates the magnetic force on the exposed face, greatly enhancing holding power while protecting the magnet and enabling easy installation via screws, bolts, or countersunk holes. They are ideal for mounting, lifting, holding, and fixing objects in construction, engineering, automotive, metalworking, warehouses, offices, and home environments.
At MAG SPRING, we provide customizable Neodymium Cup Magnets with various sizes, holding forces, coatings, and mounting options (including countersunk) to meet your precise requirements.
