Product Description

D4-cylinder-neodymium-magnet (2)

Rod / Bar magnets have a classic cylindrical design. Their diameter is generally smaller than their height, or the same diameter and height. We can produce strong neodymium cylinder magnets of different heights and diameters, which achieve very high adhesive forces even at small sizes.

Cylinder Neodymium Magnet Advantages

NdFeB-material

1.Material

Sintered NdFeB permanent magnets are smelted by an airflow mill and have a high coercive force and high magnetic energy, with a maximum magnetic energy product (BHmax) more than 10 times higher than a Ferrite magnet.

2.World's most precise tolerance

±0.01mm~±0.05mm or as per customers' request.

3.Coating / Plating

Our nickel-plated magnets are triple-plated with layers of nickel, copper, and nickel again. This triple coating makes our magnets much more durable than the more common single nickel-plated magnets.
Other options for coating are Zn, Epoxy, Silver, Gold, and Chemical nickel-plating.

4.Magnetic Direction: Axial

Axially magnetized cylindrical magnets have their maximum pull force at the ends of the magnet. Diametrically magnetized cylindrical magnets have their maximum pull force at the curved surface of the magnet.
