Steel 7" D Swivel Bearing with Stop, Rev-A-Shelf, 4SBS-7-1

Steel Construction and a Built-In Stop for Controlled Rotation

This Rev-A-Shelf 7-inch steel swivel bearing is the motion hardware at the center of a lazy susan assembly, designed for kidney or D-shaped shelves that need rotation limited by a built-in stop.

Key Features

• 7-inch diameter steel bearing provides a compact footprint suited to smaller lazy susan assemblies.
• Built-in stop mechanism limits shelf rotation to prevent overtravel and keep the shelf aligned with the cabinet opening.
• Steel construction delivers solid load support at the center shaft of the assembly.
• Designed for kidney and D-shaped shelves where controlled arc rotation is required rather than full 360-degree spin.
• Rev-A-Shelf replacement and accessory part integrates with compatible Rev-A-Shelf lazy susan systems.

Where the Stop Makes the Difference

A full-circle lazy susan spins freely and stops wherever it lands. A kidney or D-shaped shelf is a different animal: it has a cutout that needs to line up with the cabinet face opening so items can be loaded and removed without catching on the frame. The stop on this bearing is what enforces that alignment. At the limit of rotation, the shelf parks in the correct position rather than drifting past it. For a lazy susan in a blind corner or a two-shelf pie-cut cabinet, that repeatable stop position is what makes the unit usable in daily practice.

Steel at the Core

The bearing is steel, which puts a durable material at the pivot point where the full weight of a loaded shelf set transfers through the center of the assembly. Steel holds its shape under repeated loading in a way that softer materials may not over years of use. At 7 inches in diameter, this bearing is sized for the smaller lazy susan configurations rather than the larger 10-inch hardware used in bigger cabinet openings.

Who Reaches for This Part

This bearing is the right call for a cabinet shop building a new lazy susan unit around kidney or D-shaped shelves, for a homeowner replacing a worn or failed bearing in an existing assembly, or for a contractor sourcing the hardware component of a custom corner cabinet build. It is also the correct choice when an existing system uses a stop-style bearing and the replacement needs to match that function. If the application calls for free 360-degree rotation without a stop, the no-stop version of this bearing is the appropriate pick instead.

Common Questions

The Right Bearing Keeps the Shelf Where It Belongs

When a lazy susan needs to stop in the same position every time, this 7-inch steel bearing with its built-in stop is the component that makes it happen, in a new build or as a direct replacement.
