This Rev-A-Shelf 4SB Series swivel bearing gives a kidney or D-shaped lazy susan shelf a controlled rotation path, stopping shelf travel at the right point so the unit does not over-rotate inside the cabinet.
A lazy susan without a stop can spin past its intended position, pulling a loaded shelf into the cabinet wall or misaligning it with the door opening. The built-in stop on this bearing sets a defined endpoint so the shelf lands in the right place each time. That matters most on kidney and D-shaped shelves, where the cutout has to line up with the cabinet frame for the shelf to clear properly. Pair this bearing with a matching shelf set to build a corner cabinet that operates cleanly from day one.
The bearing is stamped and formed steel, chosen for its load tolerance and resistance to deformation under the weight of a stocked shelf. At 10 inches in diameter, it spans the center post connection with enough surface area to distribute the shelf load evenly across the rotation point. The 4SB Series fits the standard hub geometry used across Rev-A-Shelf's kidney and D-shaped shelf lines, so sourcing a replacement or completing a new build from familiar components is straightforward.
The 10-count pack suits a cabinet shop building out a run of corner cabinets, a contractor outfitting multiple kitchens, or a remodeler who wants spares on hand without placing a second order mid-job. Homeowners replacing a worn or missing bearing on an existing lazy susan will also find the quantity useful for a bathroom vanity or a pantry corner unit. This bearing is for indoor cabinet installations; it is not rated for exterior or high-moisture environments.
This bearing is designed for kidney and D-shaped lazy susan shelves where the stop function is needed to align the cutout with the cabinet opening. Full-circle shelves that rotate freely without a stop use a different bearing in the 4SB Series.
Kidney and D-shaped shelves have a cutout that must align with the cabinet door opening for the shelf to clear the frame. A stop limits rotation so the shelf returns to that aligned position rather than spinning past it and jamming against the cabinet wall.
Both. The bearing works as a direct replacement for a worn or damaged swivel on an existing Rev-A-Shelf kidney or D-shaped unit, and it is also the correct component for new cabinet builds using the 4SB Series hardware.
Each pack contains 10 steel swivel bearings with stop, all the same size and specification.
Specify this bearing when the build calls for a kidney or D-shaped shelf that needs a defined stop, and stock the 10-count pack to keep the job moving without waiting on a reorder.
