Steel balls and precision products manufacturer
with the world’s leading spherical surface processing technology

Smooth and accurate rotation is only achieved by creating a ball that is as close as possible to a perfect sphere. Such high precision
rotation can be applied to fields from home appliances to space science and technology. We aim to create perfectly spherical precision balls in
a diverse range of materials for various uses, and develop precision machinery that enables smooth motion.
