MSA Magnetics rare earth pot magnet, 16mm diameter

The MSA B Series is a range of rare earth pot magnets with a straight hole. There are 10 sizes, from 16mm to 88mm in diameter, with attraction from 4kg to 180kg.

A pot magnet is a magnet set in a steel shell, so that it holds on its open flat face. The range is neodymium magnets. The B Series has a straight centre hole, so the magnet can be fixed with a screw or bolt through the hole. It has the two hole diameters (D1 and D2) for each size and does not name a screw size. It has attraction in kilograms and dead weight in grams for every size.

Key specifications

Choosing the right option

Choose the size on the attraction figure and the space you have: attraction rises with diameter, from 4kg at 16mm to 180kg at 88mm. Holding force falls on thin, rough, painted or curved steel and the figure makes no allowance for that, so keep a margin and test on your own steel. It has attraction, not a safe working load: do not use a pot magnet to lift or suspend a load where a fall could cause injury. Rare earth magnets are strong and brittle: handle them with care, keep them clear of pacemakers and electronic media, and do not let two magnets snap together.
