Neodymium Pot Magnet Round Cup Magnet with Countersunk Hole Industrial Holding Magnetic Base

Counterbore pot magnets are one of the most practical structural magnetic components for modern industrial installation. The integrated sink hole design allows direct screw locking, completely simplifying the traditional magnet installation process that requires adhesive, brackets or welding. The flush mounting structure ensures no protruding parts, keeping equipment surface flat and avoiding mechanical interference during operation.

Built with high-strength sintered NdFeB core and thickened steel cup shell, these pot magnets form a closed magnetic circuit structure. This design concentrates almost all magnetic flux on the working adsorption surface, providing far stronger and more stable holding force than bare magnets of the same volume. The outer steel shell also effectively protects the internal brittle magnet core from cracking, collision and abrasion, greatly improving overall durability.

All counterbore holes are precisely machined to match standard flat-head screws, ensuring smooth assembly and tight locking. Even under long-term high-frequency vibration, reciprocating movement and heavy load adsorption, the magnets maintain stable positioning without offset or falling off. Standard nickel plating provides excellent anti-rust, anti-oxidation and wear resistance for long-term workshop and production line use. Optional epoxy waterproof coating and high-temperature resistant grades adapt to humid, outdoor and high-heat industrial working conditions.

We provide complete magnet grade options including conventional N35-N52 room-temperature grades and SH/EH high-temperature resistant grades. A full range of standard specifications are in stock for fast delivery. Customized overall size, sink hole aperture, thickness and surface treatment are all available to meet personalized mechanical design requirements.

Widely applied in CNC fixture positioning, automation equipment base fixing, workshop tool holders, mechanical testing instruments, advertising bracket installation, mold auxiliary positioning and industrial assembly scenarios. Both small sample trial orders and large-batch bulk wholesale are supported with strict quality inspection to ensure stable batch consistency.
