Material: The rotary bearing is made of high-quality steel with a galvanized surface, providing durability, corrosion resistance, and long service life. It features a solid steel construction that rotates smoothly and quietly. 360-Degree Rotation: Designed for free rotation, the bearing contains multiple steel balls positioned between the upper and lower plates, enabling smooth 360-degree movement along a lubricated path to meet everyday needs. Design: Engineered for high wear resistance, the bearing includes full round raceway grooves that support load distribution. The turntable incorporates spacer elements to maintain ball separation, minimizing friction and ensuring smooth operation. Package Includes: 1 turntable (9.5 x 9.5 cm, 4 inches) with integrated steel balls. The unit is built to withstand heavy pressure and resists deformation. Supports a load capacity of up to 30 kg (66 lbs). The assembly uses a riveted internal and external structure to ensure long-term rotation and prevent ball detachment. Wide Application: Suitable for furniture assembly, this swivel bearing is ideal for use in stools, bar stools, chairs, and seating in marine environments. Also compatible with rotating shelves in corner cabinets, display stands, magazine racks, TV mounts, computer monitor stands, and other rotating platforms.
