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