Timken bearings return to Mars

Written by: Timken | Published:

Timken bearings landed on Mars last month as NASA landed its largest rover to date, Curiosity. Timken bearings support critical functions onboard the robot such as instruments including a spectrum analyser that requires advanced motion control and a miniature pump.

The centre hub of Curiosity's carousel system rotates on Timken bearings, positioning sample cups. In addition, the vacuum pump, the size of a "D" cell battery, supports the analytical equipment utilising two miniature Timken bearings with an outer diameter of just 0.25 inches.
