High-precision ceramic sliding bearings *Integrated production from granulation to processing
Do you have concerns about issues such as specified surface roughness, clearance accuracy, cylindricity accuracy, or dimensional accuracy being poor?
We have developed high-precision, high-durability ceramic sliding bearings by applying the molding technology and ultra-precision processing techniques cultivated in the manufacturing of watch bearing stones. Due to their high reliability, we have received numerous inquiries and are supplying them to the market. Our unique precision inner diameter grinding technology and cylindrical grinding technology achieve a level of precision and surface roughness that surpasses that of metal bearings, contributing to high wear resistance, excellent quietness, and extended lifespan. Additionally, ceramics excel in wear resistance, which reduces the generation of wear particles, and their high rigidity prevents deformation even when subjected to impacts such as drops. Leveraging our advanced production technology, we deliver mass-produced, consistently high-quality bearings. ■ Features Our near-net shaping, honed through the manufacturing of watch bearing stones, minimizes unnecessary material input and excessive waste from grinding, contributing to the SDGs. We use zirconia material with a thermal expansion coefficient close to that of SUS materials commonly used for shafts. ■ Molding and precision processing technologies developed in the manufacturing of watch bearing stones ■ Achieving superior inner diameter precision and surface roughness compared to metal using precision inner diameter grinding technology ■ Contributing to noise reduction and extended lifespan due to high wear resistance ■ Reducing the generation of wear particles due to excellent wear resistance ■ High rigidity prevents deformation even when subjected to impacts such as drops.
