Bearings On Mission To Mars
02 November 2012
The Curiosity rover that landed on Mars in early August features the largest, most advanced scientific payload of any Mars mission yet and, as in previous missions, Kaydon Reali-Slim thin section bearings were selected for a range of tasks.

These components have a proven track record for saving space and weight without compromising performance. In the UK and wider Europe, Kaydon’s sole UK representative R. A. Rodriguez, regularly supplies Reali-Slim bearings to the aerospace and defence sectors for a variety of mission critical applications.
The five pairs of duplexed bearings specified for Curiosity operate in two important areas: a mechanism for preparing rock material samples for analysis and supporting the steering actuators for the rover’s wheels.
One pair of Reali-Slim bearings is in the Collection and Handling for In-Situ Rock Analysis (CHIMRA) system, one of a number of devices mounted on a turret at the end of the robotic arm.
