Carries axial load from both directions, radial load and tilting moments in a single row — the four point contact raceway geometry lets one unit do the work of two opposed bearings. Supplied without gear teeth, so rotation is driven externally rather than through a pinion. Height is 56.0 mm and net mass 32.0 kg, a figure to plan for when handling the ring during fitting. Radial internal clearance is Standard_SL. Running behaviour depends on flat, rigid mounting faces: a slewing ring draws its stiffness from the structure it is bolted to, and distortion of the seats passes straight into the raceway. Suited to slow rotary or oscillating motion with the load introduced through the bolt circle.
