Multiple Sizes Optional: Our heavy-duty aluminum alloy rotary bearing is available in multiple sizes: 4 inch and 6 inch. It features a thickened design that enhances load-bearing capacity. All detailed dimensions are shown. Race Ball Bearing Path for Smooth Rotation: The orderly row of bearing balls ensures smooth rotation for lazy susans. It includes non-slip rubber feet. The rubber feet can be removed, and the turntable can be secured with screws using the provided through-holes and pre-drilled holes. Wide Applications: Ideal for cake decoration, TV monitor stands, electronic repair, sculpture displays, catering services, food presentation, and more. Product Information: Bearings use rolling elements to maintain separation between moving parts, reducing rotational friction and supporting radial and axial loads. Sealed bearings are oil lubricated. Premium Materials and High Performance: Made from heavy-duty aluminum alloy, this product is strong, durable, and corrosion resistant, offering superior performance compared to standard plastic lazy susan bearings. It is compatible with top materials such as wood, glass, and marble to suit various styles.
