Triangle Manufacturing 12" D Zinc Swivel Bearing, - 12D8316

Positive Stops at 0 and 90 Degrees, Built Into a 12-Inch Steel Bearing

This Triangle Manufacturing 12-inch swivel bearing is a zinc-plated steel rotating platform component for lazy Susan cabinet systems, with two built-in detents that lock rotation at 0 and 90 degrees.

Key Features

• Two-detent design registers the bearing at exactly 0 and 90 degrees so shelves return to a predictable aligned position.
• 12-inch diameter suits a standard round or kidney-shaped lazy Susan shelf assembly.
• Zinc-plated steel construction gives the bearing durable, corrosion-resistant performance inside a cabinet.
• Low-profile 5/16-inch height keeps the bearing slim and the shelf ride height close to the cabinet floor.
• Designed for lazy Susan hardware applications as a direct component in corner cabinet rotating systems.

Where the Detents Make the Difference

A free-spinning bearing lets a lazy Susan shelf stop anywhere, which means a loaded shelf can drift and leave items swinging past the cabinet opening. The two detents in this bearing click the rotation into place at 0 and 90 degrees, so the shelf faces the opening squarely when the user expects it to. That predictable stop point matters most in a corner base cabinet where the shelf path swings past a fixed opening, and where an uncontrolled stop leaves the shelf angled into the cabinet wall instead of aligned with the door.

Steel Construction with a Zinc Finish

The bearing body is steel with a zinc plating, a combination that handles the repeated rotational load of a loaded kitchen shelf without rusting out inside a base cabinet. At 5/16 inch tall, the bearing sits low between the cabinet floor and the shelf above it, which keeps the shelf height practical and avoids eating into usable storage depth. The round profile mounts cleanly to a flat surface, and the 12-inch diameter matches the standard shelf sizes used in most corner lazy Susan builds.

The Right Fit for Corner Cabinet Builds and Repairs

This bearing is a working component for cabinet shops building corner base cabinet units with rotating shelves, and for homeowners or contractors replacing a worn or free-spinning bearing in an existing lazy Susan. The detent positions suit the standard cabinet opening geometry where a shelf that stops at 0 or 90 degrees is aligned with the door rather than partially blocked by the cabinet face frame. It is an indoor cabinet part intended for dry storage environments.

Controlled Rotation for a More Predictable Lazy Susan

Choose this bearing when a free-spinning platform is not enough and a shelf that stops in the right place every time is what the cabinet needs.
