CEROBEAR from Herzogenrath developed 50 bearing types for the Mars rover "Perseverance".
They have to withstand a six-month journey through space, extreme vibrations and temperature fluctuations: The demands on the components of the Mars rover "Perseverance" are extreme. Thanks to its many years of expertise in space applications, a North Rhine-Westphalian company has been able to meet precisely these demands: CEROBEAR from Herzogenrath near Aachen developed 50 bearing types exclusively for the Mars rover, which were installed in the rover's wheels, robot arm and sample acquisition system, among other things.
Now with a staff of 130 employees, CEROBEAR has been on the market since 1989 and, according to its own statements, is the leading manufacturer of all-ceramic and hybrid-ceramic rolling bearings as well as a pioneer in rolling bearing technology. The company was founded as a spin-off of the Fraunhofer Institute for Production Technology (Aachen). Since 2013, CEROBEAR has been part of the MinebeaMitsumi Aerospace NHBB/myonic Business Unit of the global MinebeaMitsumi Group.
