For those troubled by distortion and unusual noises in housing holes! We solve this with precise inner diameter tolerance processing, preventing bearing play and achieving smooth rotation.

Do you have any of these concerns? - Excessive load on bearings due to inner diameter deformation after press-fitting, causing abnormal noise. - Geometric tolerances (coaxiality, perpendicularity) of cast iron housings not being met, leading to shorter bearing life. - Chucking distortion occurring during machining of thin-walled sections, resulting in high scrap rates due to exceeding dimensional tolerances. Kyowa Seiki's "Cast Iron Bearing Holder Precision Machining Contract Service" fundamentally resolves these issues. ◇ High-precision inner diameter machining that achieves roundness and coaxiality ◇ By employing jigs and machining approaches that consider clamping distortion and deformation from machining heat in cast iron materials, we reliably maintain fine inner diameter tolerances. ◇ Precision lathe technology that prevents deformation even in thin-walled sections ◇ Our unique clamping technology and NC lathe machining significantly reduce defect rates, even for thin-walled shapes. ◇ Reduction of total costs through the utilization of black skin surfaces ◇ We propose blank designs that leave black skin on the outer circumference and non-precision surfaces. This shortens the cutting process while providing high quality at low prices. *For more details, please download the catalog or feel free to contact us.
