The "magnetic fluid seal" is a seal that uses magnetic fluid, which has the characteristic of being attracted to magnets. By fixing the magnetic fluid around the rotating shaft with a magnet and creating a fluid O-ring, a clean seal without solid sliding has become possible. It is used as a vacuum seal and dust seal in semiconductor manufacturing equipment, liquid crystal panel manufacturing equipment, and solar panel manufacturing equipment. 【Features】 ■ Seal using magnetic fluid ■ Clean seal without solid sliding is possible ■ Achieves vacuum level of 10^-9 Pa and heat resistance of 220°C (for semiconductor manufacturing equipment) *For more details, please refer to the PDF document or feel free to contact us.
