Triangle Manufacturing 3" D x 5/16" H Zinc Swivel Bearing, - 3C

Triangle Lazy Susan Swivel Bearing For Heavy Turntables

Triangle lazy susan swivel bearing is a 3 inch by 3 inch steel square bearing designed to support rotating shelves and platforms in kitchen and bath applications. The zinc coated construction resists rust, which helps the bearing maintain performance in typical indoor humidity around cabinets and storage areas. A weight capacity of up to 1,000 lb allows this bearing to support demanding loads, so larger lazy susan trays or heavy stored items can rotate without overloading the hardware. The bearing is only 5/16 inch thick, so it fits into tight vertical spaces inside cabinets where clearance is limited. It can be recessed into surfaces to reduce the exposed space to about 1/8 inch, helping keep the turntable profile low while still allowing free rotation. The bearing can also be inverted, giving flexibility in how the assembly is built depending on cabinet layout.

Key Swivel Bearing Details That Support Your Build

• The steel square swivel bearing is zinc coated for rust resistance, which helps maintain smooth turning in typical cabinet environments over extended use where moisture can be present.
• A weight capacity of up to 1,000 lb allows the bearing to handle substantial lazy susan loads, so large diameter trays and densely loaded shelves can rotate without stressing the rotating joint.
• The 3 inch by 3 inch square format gives a compact footprint, so the bearing can be integrated into smaller corners or tighter base cabinet spaces while still centering the rotating platform.
• At only 5/16 inch thick, the bearing works where vertical space is limited, helping keep shelf height practical while still providing a functional rotating base for stored items.
• The bearing can be recessed to reduce exposed thickness to about 1/8 inch, supporting low-profile turntable designs that align closely with surrounding cabinet surfaces.
• A 360 degree interlock prevents separation of moving parts, which keeps the bearing assembly captive during rotation and maintains alignment over the lifetime of the unit.

Installation And Fit Details For This Swivel Bearing

The 5/16 inch thick bearing body gives a predictable stack height in a lazy susan assembly, so the installer can plan shelf and door clearances around that dimension. Because the unit can be recessed to around 1/8 inch exposed thickness, builders can create turntables that sit closer to the cabinet floor or shelf, which helps keep stored goods at a convenient reach height. The ability to invert the bearing offers flexibility in where the fixed and rotating faces are oriented, which can simplify aligning the rotating tray with cabinet geometry. The 3 inch by 3 inch square format centers easily on typical round lazy susan trays, making layout straightforward when marking attachment points on wood or composite panels.

How This Triangle 3C Swivel Bearing Works In Use

Where This Lazy Susan Steel Square Swivel Bearing Fits

This lazy susan steel square swivel bearing is part of the Triangle Manufacturing range, positioned for kitchen and bath cabinet applications where a compact, strong rotating joint is needed. The 3 inch by 3 inch square size suits corner cabinets and other confined spaces where the bearing must sit within narrow framing while still centering a round or polygonal tray. With up to 1,000 lb weight capacity, it supports turntables that carry heavy cookware, small appliances, or dense pantry items, so the rotating shelf can serve both residential and shop storage roles. The zinc coated steel construction resists rust, which is useful in base cabinets near sinks or dishwashers where moisture exposure is common and corrosion resistance helps preserve smooth movement.

Design Details That Support Smooth, Repeatable Rotation

The large ball race is designed for maximum stability, so the rotating tray rides on a broad path of balls that spread load and help maintain level movement under heavier stacks of goods. Single piece construction, pre-assembled so there is no contact under load except through the rolling balls, reduces friction points, which supports smoother rotation and helps reduce wear at the interfaces. The 360 degree interlock keeps the bearing halves engaged for the lifetime of the unit, so the moving parts stay captured even when the turntable is heavily loaded or rotated repeatedly, which protects against separation during long-term service. The option to recess the bearing into the mating surfaces further stabilizes the assembly by locating the bearing within a pocket, helping control lateral shift and contributing to consistent tracking. Because the bearing can also be inverted, installers can select the orientation that best supports alignment of the tray surface with surrounding cabinetry, which assists in achieving even reveals and repeatable rotation without binding.

Common Questions About This Triangle Swivel Bearing

Select This Bearing For Demanding Lazy Susan Loads

This Triangle Manufacturing 3 inch by 3 inch zinc swivel bearing is built for lazy susan and similar turntable applications that demand high load capacity and stable movement. The combination of up to 1,000 lb rating, large ball race, and 360 degree interlock supports repeatable rotation where heavy contents must move smoothly. The 5/16 inch thickness, with the option to recess to about 1/8 inch exposed, helps fit this bearing into tight cabinet spaces while keeping tray height practical. For projects handled through Wurth Baer Supply that call for a compact, rust resistant rotating joint, this bearing provides a defined footprint and performance characteristics that align with heavy-duty lazy susan hardware needs.
