Triangle Manufacturing 4" D Zinc Swivel Bearing, - 4C

4-Inch Swivel Bearing for Lazy Susan Cabinet Builds and Repairs

This Triangle Manufacturing 4-inch zinc swivel bearing provides the rotating pivot point for a lazy susan shelf system, supporting smooth rotation in a compact steel footprint suited to smaller cabinet applications.

Key Features

• 4-inch diameter steel bearing delivers a solid swivel base sized for compact lazy susan installations.
• Zinc finish over steel construction resists corrosion and stands up to the demands of a working cabinet interior.
• 5/16-inch profile height keeps the bearing low so it adds minimal thickness between shelves and mounting surfaces.
• Square plate design provides four mounting points for a secure, stable attachment to the shelf or cabinet base.
• Compatible with lazy susan shelf hardware as a swivel component for new builds or as a replacement in an existing system.

Where This Bearing Fits the Job

A swivel bearing is the mechanical heart of any lazy susan: the fixed plate mounts to the cabinet floor or shelf board, the rotating plate turns with the shelf above it, and the load rides on the ball-bearing race between them. This 4-inch bearing is sized for smaller-diameter lazy susan shelves, the kind that fit a narrow corner base cabinet or a pantry unit where a full-size bearing plate would crowd the shelf. It also comes up as a direct replacement when an existing bearing wears out or fails, letting a shop or homeowner restore rotation without replacing the entire shelf assembly.

Steel Body, Zinc Finish, Low Profile

The bearing is built from steel and finished in zinc, a combination that gives the hardware the structural integrity to carry shelf loads without flexing while the zinc coating keeps surface corrosion at bay inside a cabinet environment. At 5/16 inch tall, the bearing stays out of the way between the shelf and whatever surface it mounts to. The square plate geometry puts a fastener point at each corner, distributing the load evenly and keeping the shelf from wobbling under rotation.

Who Reaches for This Bearing

Cabinet shops building corner or pantry units in smaller cabinet runs will use this bearing to set the rotation point on a 4-inch-diameter swivel assembly. Contractors replacing worn hardware on an existing lazy susan grab it as a direct swap. Homeowners doing a cabinet refresh can swap out a failing bearing without sourcing a full replacement kit. The compact size makes it the right call wherever a larger bearing would intrude on shelf clearance or the cabinet opening is tight.
