10-Inch Swivel Bearing for Kidney and D-Shaped Lazy Susans

This Rev-A-Shelf 4BS aluminum swivel bearing is the pivot hardware for kidney-shaped and D-shaped lazy susan shelves, and it includes a built-in stop to control shelf rotation.

Key Features

10-inch diameter sized for standard kidney and D-shaped lazy susan shelf assemblies.
Built-in stop mechanism limits rotation so shelves stay oriented correctly inside the cabinet.
Aluminum construction keeps the bearing lightweight without sacrificing structural support.
4BS series compatibility designed specifically for kidney and D-shaped shelf formats, not full-circle susans.
Pack of 8 supplies enough bearings for a multi-shelf installation or a shop keeping hardware on hand.

Where the Stop Makes the Difference

Kidney and D-shaped lazy susan shelves are designed to swing out through the cabinet opening and then stop at a usable position. Without a bearing that limits rotation, those shelves can spin past the door opening and bind against the cabinet frame. The stop integrated into this bearing controls where the shelf halts, so the rotation path matches the cabinet door swing and the shelves land where they are meant to land. That makes this bearing the right choice for any kidney or D-shaped installation, and the wrong choice for a full-circle susan that is meant to spin freely.

Material and Build

The bearing is aluminum, which keeps the rotating mass low and resists the corrosion that can seize a steel bearing over time in a kitchen environment. At 10 inches in diameter, it fits the center-shaft location in a standard kidney or D-shaped shelf stack. The 4BS series is the Rev-A-Shelf line built around this specific shelf geometry, and this bearing is the hardware that makes the rotation work.

Who This Is For

Cabinet shops building or replacing kidney and D-shaped lazy susan assemblies will go through bearings in volume, and the pack of 8 supports that workflow without repeated reorders. Homeowners and contractors replacing a worn or failed bearing on an existing installation get enough hardware to address multiple shelves at once. If the cabinet uses full-circle shelves that spin without a rotation limit, the 4B series bearing without a stop is the correct choice for that application.

Common Questions

What is the difference between this bearing and the full-circle version?

This 4BS bearing includes a stop that limits rotation, which is required for kidney and D-shaped shelf layouts. Full-circle lazy susans rotate continuously and use a bearing without a stop. Using a stop bearing on a full-circle installation will restrict the spin, and using a non-stop bearing on a kidney or D-shaped shelf will let the shelf rotate past the door opening.

Does this bearing fit both kidney and D-shaped shelves?

Yes. The 4BS series is designed for both kidney-shaped and D-shaped lazy susan shelf formats. Both configurations use a rotation stop, and this bearing supports either.

How many bearings come in a pack?

This listing includes 8 bearings per pack.

Will this bearing work with steel shaft components?

The bearing itself is aluminum. Shaft and pole components are sold separately; confirm compatibility with the specific shaft or center pole in your installation before ordering.

The Right Bearing Keeps the Shelf in Place

Choose this 10-inch aluminum bearing when the job calls for a kidney or D-shaped lazy susan that stops at the door opening rather than spinning past it.
