Rotary bearings

Slewing ring bearings are a type of ball or roller bearing. They are large bearings that allow rotation between various components in large structural systems, also known as turntable bearings.
Turntable bearings can be equipped with mounting holes for easy attachment to a flat surface. This feature adds versatility in situations that require precise positioning without compromising other important aspects.
Slewing ring bearings are often chosen for their ability to withstand static loads. They can withstand axial and radial static loads and even overturning moments.
