According to practical application, NdFeB (neodymium) cup/pot magnet can be equipped with various hooks, rings, and bolts. Neodymium pot magnets with bolts are also called neodymium ring bolt magnets. Big neodymium ring bolt cup/pot magnets are used as strong search magnets to get ferromagnetic objects from deep water, caves or anywhere you can't reach with your hands
Component and Material: neodymium countersunk ring magnets + A3 steel cup + ABS plastic ring or epoxy glue+ring bolts
Available Surface Treatment: Nickel, Zinc, spray colorful plastic
Standard Size: diameter-20mm, 25mm, 32mm,36mm,42mm,48mm,60mm,75mm
Magnetic Grade：N35, N38, N40, N42, N45,N48,N50,N52
Working Temp.: -40 to 80℃（for standard ones), the pot magnets for higher working temperature can be customized
Remind: Although the surface of the neodymium pot (cup) magnet with ring bolt has been anti-rust treated with electroplating, if it is not used and stored properly, it will still rust. Please store rare earth ring bolt pot magnets in a dry and room temperature environment, preferably in a sealed bag.
1. Rera earth pot magnet with ring bolt has super strong magnetic force, the max breakaway force of the D75mm pot magnets is up to 160kgs.
2. There is almost no magnetic force on the surfaces of the steel side because all magnetic lines of force of the countersunk magnet are concentrated on the working surface.
3. Each countersunk neodymium cup magnet is assembled with a strong eye bolt.
4. The inside countersunk neodymium magnets is made with Ni-Cu-Ni coated.
