Thin and light! Kaidon "Ultra-thin Ball Bearing"

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.

Kaidon ultra-thin bearings are making a big impact in missions in harsh space environments!

Kaidon ultra-thin bearings perform well even at an altitude of 400 km.

In a space environment, lightweight and space-saving designs are required, and precise movements are demanded under vacuum conditions and a wide temperature range, making it a very harsh environment for bearings to operate in. KAYDON's Reali-Slim has achieved smooth rotation in space for many projects, including the next-generation space environment work robot CAESAR. A stainless steel series suitable for space is also available in a wide range of sizes, up to 25 inches. Based on over 75 years of experience, we provide bearings that are optimal for the operating environment. **Benefits of Choosing KAYDON** - Minimizes the space occupied by bearings in equipment - Reduces the weight of the equipment - Allows for larger diameters of hollow shafts, enabling internal wiring - Prevents outgassing by changing bearing materials - Applicable to various environmental temperatures - High rigidity achieved by adjusting internal gaps - Bearing precision can also be adjusted **Examples of Adoption** - Satellites - Space stations - Space telescopes - Space probes - Space environment work robots, and more **You can download examples of the adoption of the space robot CAESAR from here.**
