Satellite Bearings

Satellite bearings are high precision, high reliability products that support onboard systems such as reaction wheels, flywheels that are used for attitude control in the X, Y, and Z axes and that rotate by very small degrees.

Reaction wheel bearings must withstand vibrations and spin reliably for years in the vacuum of space, and with only small amounts of lubricating oils.

Gimbal Bearings

Gimbal bearings are precision components that help position engines for maximum thrust. They are used with gimbals, devices that consist of at least two rings attached to each other axially at 90 degrees.

Gimbal bearings are designed to provide low torque and high stiffness. Types include radial, angular, four-point, and double angular. The ring material provides corrosion resistance.

Built for Space

Our bearings for spacecraft and satellites meet ABEC 1F, 3F, 5F, or 7F precision levels. Like other types of space bearings, they feature a stainless steel construction and support lubrication for specific applications.

Schatz space bearings can resist corrosion and are designed to withstand violent shaking and sustained acceleration forces.
