Steel 10" D Swivel Bearing with Stop, Rev-A-Shelf, 4SBS-10-1

10-Inch Steel Swivel Bearing for Kidney and D-Shaped Lazy Susans That Need a Fixed Stop

This Rev-A-Shelf 4SBS-10-1 is a steel swivel bearing designed to support and rotate a 10-inch lazy susan shelf, with a built-in stop that limits rotation to a set arc rather than allowing continuous full-circle spin.

Key Features

• 10-inch diameter steel bearing provides the rotational support for a lazy susan shelf at the 10-inch footprint.
• Built-in stop mechanism limits travel so the shelf returns to and holds a defined position rather than spinning freely.
• Steel construction handles repeated loading and rotation without the flex of lighter bearing materials.
• 4SB series hardware integrates with other Rev-A-Shelf lazy susan components in the same series for consistent builds and retrofits.
• Intended for kidney and D-shaped shelf formats where a stop is required to orient the shelf opening correctly at the cabinet door.

Where the Stop Makes the Difference

A kidney or D-shaped lazy susan has a notched edge that is meant to align with the cabinet door opening so contents can be reached without obstruction. Without a stop, the shelf can rotate past that position and the notch ends up facing the cabinet wall, making the unit much harder to use. The stop in this bearing locks the travel arc so the shelf presents correctly every time the door is opened. That alignment is what separates a D-shaped susan from a full-circle unit, and it is also why a bearing with a stop is the right choice for this shelf format rather than a no-stop version from the same series.

Steel at the Core

The bearing is stamped and formed steel rather than aluminum or polymer, which gives it a stiffer rotational platform under load. Steel bears up better under a shelf stacked with canned goods or heavy pantry items, and it does not develop the gradual deflection that lighter materials can show over time in a frequently used corner cabinet. The 4SBS-10-1 belongs to the Rev-A-Shelf 4SB series, a line built specifically as lazy susan hardware, so replacement parts, shafts, and shelf supports in the same series are readily available when rebuilding or upgrading an existing installation.

Right Fit for Corner Cabinet Builds and Repairs

This bearing suits two common scenarios. The first is a new build where a cabinet shop or installer is constructing a kidney or D-shaped lazy susan from components and needs a 10-inch bearing with a stop at the core. The second is a repair or upgrade situation where an existing bearing has worn out or was specified incorrectly and needs to be swapped for the right unit. Confirm the shelf format before ordering: this bearing is for kidney and D-shaped shelves that require a stop. For a full-circle shelf that rotates without a stop, the 4SB-10-1 from the same series is the correct choice.

Common Questions

The Right Bearing Keeps the Susan Where It Belongs

Choose this 10-inch steel bearing with stop when the job calls for a kidney or D-shaped lazy susan that needs to align reliably at the cabinet opening, built tough enough to handle a working pantry corner cabinet over the long term.
