Achieved a cross-sectional dimension of just 4.76mm. Increased design flexibility due to space-saving and lightweight features.
Kaidon’s "Ultra-Thin Ball Bearings" feature a small cross-sectional dimension, achieving space-saving and lightweight design, which enhances design flexibility. The inner diameters range from 25.4 to 1016 mm, with a wide lineup of cross-sectional dimensions from 4.76 to 25.4 mm. There are four-point contact types, angular contact types, and deep groove types, suitable for use in special environments. 【Features】 - As a specialized manufacturer, we have established a mass production system that can accommodate short delivery times. - Being ball bearings, they achieve stable low torque and high rotational accuracy. - Custom solutions are available for general industrial applications, aerospace and defense applications, semiconductor manufacturing equipment, medical devices, etc. - In addition to standard bearing steel, materials for corrosion-resistant applications are also available (such as SUS440C stainless steel and EnduraCoat). - We have a proven track record of providing hybrid types using ceramic balls for vacuum environments, such as those for semiconductor manufacturing equipment. - The four-point contact type, which can handle combined loads with a single bearing, achieves further space-saving and lightweight design by replacing combination bearings with angular contact types. *For applications requiring even thinner cross-sections, please consider the "Ultra Slim" series.
