  • Product Detail
  • Technical Specifications
Permanent magnets encased with pot shape steel shells are named cup magnets or pot magnets.According to different magnetic materials,cup (pot) magnets are divied into pot neodymium magnet,pot alnico magnet,pot ferrite magnet.Their magnetic strength and prices will be relatively large differences.

Pot /cup neodymium magnet with screwed bush is magnetic assembly which has an externally threaded stem for mounting and known as strong mounting magnet.Thanks to the scientific magnetic circuit design,the screwed bush neodymium pot magnets have the characteristics of small volume and strong magnetic force,easy to install and flexible to use.
