Steel 10" D Swivel Bearing for Full Circle Lazy Susans No Stop, Rev-A-Shelf, 4SB-10-1

Steel Construction and Full-Circle Rotation, No Stop Required

This Rev-A-Shelf 4SB-10-1 is a 10-inch steel swivel bearing designed for full circle lazy Susan shelves, providing continuous 360-degree rotation without a built-in stopping point.

Key Features

• 10-inch diameter steel bearing delivers the structural rigidity needed for loaded full circle lazy Susan shelves.
• Full-circle, no-stop design allows continuous rotation in either direction without a rotation limit.
• Steel construction gives this bearing more resistance to flex under load than aluminum alternatives.
• Rev-A-Shelf 4SB series fits into replacement and new-build lazy Susan applications where this bearing size and material are specified.
• Sold individually so you can replace a single bearing or source exactly the quantity a multi-shelf build requires.

Where Continuous Rotation Is the Right Call

A no-stop bearing suits full circle lazy Susan configurations where shelves need to spin freely in either direction without hitting a limiting point mid-turn. That makes it the right choice for a corner cabinet where the shelves rotate through the full opening and back, and where the installer or the cabinet design itself controls the range of travel rather than a built-in detent. It also fits replacement jobs where the original bearing had no stop and the goal is a like-for-like swap that restores smooth rotation.

Steel Where Rigidity Matters

The 4SB series in steel handles the same rotation function as its aluminum counterparts but with a material that resists flex more effectively when shelves carry consistent weight across the full diameter. A 10-inch bearing centers under the shelf and distributes the load across a wider contact area than a 7-inch bearing would. Steel also holds its shape better over time in applications where the shelf is loaded and unloaded repeatedly. The trade-off is added weight relative to aluminum, which is worth considering in a lightweight build but is rarely a concern in a standard base cabinet corner unit.

Specifying the Right Bearing for the Build

Cabinet shops building new corner units and contractors replacing worn hardware in existing kitchens both reach for this bearing when the spec calls for steel, a 10-inch diameter, a full circle shelf, and continuous rotation. It fits new builds where the shelf design does not require a rotation stop, and it is a direct replacement for any existing 4SB-10 installation. If the application requires a stopping point at a set rotation, this bearing is not the right fit; step to the 4SBS-10-1 with the built-in stop instead. For a smaller shelf diameter, the 4SB-7-1 covers the same no-stop, full-circle function in a 7-inch size.

Common Questions

The Right Bearing Keeps the Shelf Moving Cleanly

Choose this 10-inch steel swivel bearing when a full circle lazy Susan calls for continuous rotation, a larger diameter, and the added rigidity of steel construction.
