Product Description

Small Pot Magnet wth Cylindrical Borehole Ø 16 X 5.2 mm, Neodymium Cup Magnets with Borehole, NdFeB Holding Magnet with Cylindrical Hole, NdFeB Through Hole Pot Magnets China Supplier

Small Pot Magnet with Cylindrical Borehole Ø 16 X 5.2 mm Part No.HS-NB16 by HSMAG Features :

Material: Housing steel and Magnetic core sintered neodymium ring magnet.
Version: Housing, galvanized. Magnet, Ni coated or Zn coated
Note: Shallow flat pot magnets with cylindrical hole. These magnets are pressed or glued into the receiving holes.
Hairline cracks in the magnetic material are unavoidable for technical reasons in the D=16 version. They do not impair the attracting function of the magnets in any way.
Temperature range: max. 80°C.

The holding surface is polished. In order to fully take advantage of the holding force specified, allow a protrusion of approx. 1.5 mm above the installation surface when installing the magnetic system or enlarge the mounting borehole around the holding surface of the magnetic system by 3-4 mm. A socket made of a non-magnetizable material (AI, Ms, Ku) is also favourable. If only a direct installation in steel is possible, a holding force reserve of 30 percent should be taken into account when selecting the size of the magnetic system. You may shorten the system by the dimension KM without reducing the holding force. Tolerances: D ± 0.1 mm, L ± 0.2 mm.

1) The holding forces have been determined on a polished plate made of steel (S235JR according to DIN 10 025) with a thickness of 10 mm by pulling the magnet vertically from the surface (1kg≈10N). A deviation of -10 % (max.) in the stated values is possible in exceptional cases. In general, the value will be exceeded. Small cracks in the magnetic material do not affect the holding force.

NdFeB Hole Pot Magnets are best for small sized magnetic products with maximum pull strength (ideally when in direct contact with ferromagnetic e.g. mild steel surfaces). The actual pull force achieved is dependent on the surface that is being clamped onto (material type, thickness, flatness, friction levels, etc), its quality (e.g. rust free), its size (thickness plus total surface area), etc.

We offer Pot Magnets in a silver (chrome, zinc or nickel) finish, a white paint finish, a red paint finish, black rubber coated finish and ferritic stainless steel finish, etc.
