Generate air vortices without contact! Ceramic air dynamic bearings have less wear compared to metal ones, even when not in motion.
At Niimi Sangyo Co., Ltd., we offer contract processing of "high-precision clearance parts made of ceramics," such as air bearing and valveless piston pumps (piston/cylinder). Since it is an air bearing, there is no wear during operation due to non-contact, but there is a risk of wear when not in operation. With Niimi Sangyo's ceramic "air bearings," the wear resistance is superior compared to metals, which reduces the risk of wear. Additionally, one of the features is the ability to create grooves at the micron level. 【Main Features】 ■ Surface characteristics suitable for the intended use ■ Excellent wear resistance ■ Excellent heat resistance ■ Excellent chemical resistance *Please check the PDF for various ceramic parts available for download.
