The Mars rover used Kaidon ultra-thin ball bearings!
Kaidon ultra-thin bearings contribute to miniaturization and space-saving of products.
In the space environment, in addition to the need for weight reduction and space-saving, bearings are subjected to extremely harsh conditions due to the requirements for precise movement in a vacuum and across a wide temperature range. Kaydon's ultra-thin ball bearings have enabled smooth rotation in space for many projects, including the Mars rover "Perseverance." 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 usage environment. **Benefits of Choosing Kaydon** - Minimizes the space occupied by bearings in equipment - Reduces the weight of equipment - Allows for larger diameters of hollow shafts, enabling internal wiring - Reduces outgassing by changing bearing materials - Applicable to various environmental temperatures - Increases rigidity by adjusting internal gaps - Allows for selection of bearing precision **Examples of Applications** - Satellites - Space stations - Space telescopes - Mars rovers - Robotics for space environments, and more **You can download the case study of the Mars rover "Perseverance" from here.**
