Swivel Bearing For a 12-Inch Lazy Susan Build

This Triangle Manufacturing 12C swivel bearing is a 12-inch round steel plate in a zinc finish, built to serve as the rotating foundation of a lazy susan shelf or tray assembly in a cabinet or pantry.

Key Features

• 12-inch diameter supports a full-size lazy susan shelf or tray without overhanging a standard base cabinet interior.
• Steel construction with zinc finish holds up to the regular load and rotation cycles of an in-cabinet turntable.
• 5/16-inch height profile keeps the bearing low so it adds minimal lift between the shelf and the cabinet floor.
• Round plate design mounts flat and distributes load evenly across the bearing surface.
• Designed for lazy susan hardware applications as a direct-fit component in new builds and replacements alike.

What This Bearing Does in a Lazy Susan Assembly

A swivel bearing is the mechanical core of any lazy susan: it sits between the cabinet floor and the rotating shelf, allowing the shelf to spin freely while carrying the weight of whatever is stored on it. The 12-inch round format suits a mid-size lazy susan shelf used in a base corner cabinet, a pantry, or a standalone turntable tray. At 5/16 inch tall, the bearing sits nearly flush, so it does not create a noticeable step between the cabinet floor and the bottom shelf surface. The zinc-finished steel holds its shape under repeated load cycles without the corrosion risk of bare steel in an enclosed cabinet environment.

Material and Build

The bearing plate is steel, finished in zinc. Zinc plating protects the steel surface and gives the hardware a clean, neutral appearance that works whether the bearing will be visible from the side or fully hidden beneath a shelf. The round form factor and flat profile make it straightforward to position and fasten during assembly. The 12-inch diameter is the nominal outer dimension of the plate itself, so confirm that your shelf diameter and cabinet opening can accommodate the full footprint before finalizing your layout.

Who Reaches for This Bearing

Cabinet shops building corner base units with lazy susan shelves will use this bearing as a standard component in volume builds. Custom furniture makers constructing freestanding turntable trays or rotating display platforms will find the 12-inch size a useful mid-range option. Homeowners replacing a worn or damaged bearing in an existing lazy susan can use this as a direct swap if the original plate was a 12-inch round. It is a single-bearing component, so mounting hardware requirements depend on the shelf and cabinet configuration being built.
