Shifting gears: simplify your design with slewing ring

A slewing ring bearing has rolling elements designed to create a reactive moment within the bearing’s dimensions envelope, to oppose applied (overturning) moment load. This makes it practical to use one bearing instead of two, reducing the height required for an appliion and often improving performance.
