I purchased this from Monotaro in April for 1,798 yen, but I ultimately have no use for it, so I'm selling it. It can smoothly rotate items weighing up to 100kg. It features a quiet, high-load design. The top and bottom plates are crimped together, so they won't come loose or detach. Mounting Pitch (mm) (Top) 136 x 110 (Bottom) 144 x 144 Applications: Turntables, TV swivel bases, etc. TRUSCO Part Number: 384-7772 Material/Finish: Steel/Tri-valent chromate plating Height (mm): 12.5 Weight (g): 898 Inner Diameter (Φmm): 70 Uniform Load Capacity (kg): 100 Outer Diameter (Φmm): 160 Mounting Hole Diameter (Φmm): 8.1
