Sakuma provides magnets for a wide array of industries and applications. Many of the products containing our magnets are used by millions of people every single day.

Our magnets utilize the light rare earth element Neodymium (NdFeB) in order to produce a good magnetic force. We ensure 0% heavy rare earth elements in our magnets, and we focus on producing magnets with China-free raw materials.

Our main supplier for magnets is Daido Electronics Company.

  • Heavy Rare Earth Element Free
  • Produced using China-free raw materials
  • Can help to achieve Carbon Reduction goals

Electric Power Steering (EPS)
