FY2018

Japan Powder Metallurgy Association New Product Award / New Design Category
Sintered oil-impregnated bearings with an inner diameter tolerance of 1μm

Porite received this award for its ability to achieve an inner diameter tolerance of 1μm with standard sizing alone, and the fact that this kind of high precision can be achieved with costs 30% lower than conventional rotational sizing.
This has enabled usage in high precision motors that have exacting demands for characteristics in terms of noise, and it is anticipated that the powder metallurgy product market will expand henceforth as ball bearings and fluid dynamic bearings are replaced.
