Rolling life properties of aqua-bearing

摘要

Bearings often operate under various corrosive conditions in equipment for semiconductor manufacturing, food processing, chemical plants, and other applications. Under such conditions, the performance and corrosion resistance of conventional bearings, such as those made of plastic or stainless steel, have not been sufficient enough to satisfy market requirements. NSK, however, has met the demands of the marketplace with its newly developed Aqua-Bearing. NSK's Aqua-Bearing is a newly developed special fluorine plastic rolling bearing for highly corrosive environments. This product exhibits excellent life properties and proves highly resistant to corrosion at the same levels expected of ceramic bearings. Rolling life of the new Aqua-Bearing is 2.5 to 6 times longer than that of conventional polyethylene and AISI440C bearings in water, water spray and dry environments. In addition, this newly developed Aqua-Bearing has a higher load capacity than that of polyethylene bearings.
