The drive system of the Mars Robot Curiosity is a very light but stable and strong thin bearing designed and manufactured by Japanese experts.
Due to the precise material , raceway design and space-proven tribology, the life of these roller bearings far exceeds the life expectancy , a previously planned two-year rover. This proves the high capabilities and outstanding know-how of Japanese manufacturers. Nachi bearings operate reliably in harsh space conditions, including temperatures between -120°C and 0°C.
These roller bearings can operate for an extremely long period of time. Thanks to their sophisticated design and high quality of the raceway surfaces, they guide the shaft with the highest concentricity very smooth, smooth and reduce friction. Due to various lubrication methods and design types (with or without protective cover and respective seals), Nachi's rolling bearings can be used in various applications such as machine tools, construction and special machinery, mining equipment, cranes, compressors, ships, roads Waiting for and railway cars.
Optimised types are available, for example very anti-vibration spherical roller bearings for special applications under extreme conditions.
As an alternative, in addition to the standard-model, high-precision ball bearing with minimal clearance, there are matched bearings, and bearing units with bearing housings.
Nachi's experts have mastered the entire production line from crude steel to manufacturing, heat treatment and assembly. So they can guarantee the highest quality.
