Fidget Spinner

A BEARING is the core component that enables the smooth and fast spinning action. WEIGHTS on each arm provide balance and inertia, allowing longer spin times. FRAME or body is usually made from plastic, metal, or ceramic for durability. CAPS are placed over the center bearing to provide a grip for fingers. SPACERS/O-RINGS may be used to adjust the balance or enhance the grip and spin feel. BEARING – 608RS stainless steel or ceramic, 22mm outer diameter WEIGHTS – Brass, steel, or aluminum, typically 5-15 grams per arm FRAME – ABS/PLA plastic or aluminum alloy, 70-90mm diameter CAPS – ABS/TPU plastic, ergonomic shape for grip, 15-20mm diameter SPACERS/O-RINGS – Silicone or rubber, varies by design for tuning spin
