This is a cylindrical ceramic ferrite magnet with a hole in the center, radial 4-pole magnetization, surface magnetic strength of about 1200 gauss, mainly used in various miniature pumps, brushless direct current pumps, cooling pumps, etc., we have a lot of specifications have stock, low price.

The following sizes are commonly used for the pump (more customers have demand):

D12.4 x d5.5 x 25/ Radial external magnetize 4 poles

D13 x d4.7 x 27/ Radial external magnetization 4 poles

D16 x d5 x 25/ Radial charge 2 pole /Y30

D16 x d5 x 20/ Radial charge 2 pole /Y35

D16 x d5.2 x 25/ Radial 2 pole /Y30


Because this magnet is generally used with glue or adhesive to install it with plastic or steel parts, the size of the magnet should match the part, and the size of the magnet is generally determined by the size of the part. If you have other size need, you can contact us and provide your requirment, we can custom the magnet for you!
