39 LB Holding Power Cup Magnet w/ Female Threaded Stud, Made of Neodymium Magnet | Strong Rare Earth Pot Magnets
This cup magnet provides a 39 LB holding power and features a #10-24 female threaded stud. This cup magnet is made of neodymium magnet which provides much stronger holding power than the cup magnets made of the ceramic magnets, specifically the holding power of this 25 mm cup magnet is equivalent to a 50 mm ceramic cup magnet RB50
The neodymium cup magnets are made of the super strong neodymium magnets encased inside the nickel plated steel cups. The neodymium magnets are bonded inside of the cups with adhesives. When the cup magnets are applied to the steel objects, the magnets, the steel cups and the steel objects form a closed magnetic circuit which triples the holding forces! At the same time, the steel cup also protects the magnets from breaking when they are used.
The cup magnets are also known as pot magnets, magnetic round bases or magnetic cup assemblies.
- Holding Force: 39 LB with a direct touch and direct pull
- Diameter: 25 mm ( 0.98" )
- Thickness: 6.25 mm ( 1/4" )
- Applications: Magnet fasteners for holding magnet, small lifting magnet, magnet Mounting, and much more
- Commercial use only. Keep it away from pacemakers and children.
The Holding Force of this cup magnet is tested per industrial standard, i.e. when the magnet directly contacts a 20 mm thick low carbon steel block with a clean and smooth surface and was pulled perpendicularly way from the contacting surface.
