Belmont Copper Triangle Spinner

One of our lighter 313inc spinner. A triangle machined lace design in beautiful copper. It houses a standard 3/16 inch R188 bearing that is a pressed fit with our polyurethane ring retention system. The ring sits in a precision groove cut to hold a bearing in place allowing for the changing of the spinner bearing in a simple and clean way. There is no adhesive used as adhesives may damage a bearing itself. We designed our retention system for the convenience of effortless bearing changes while keeping the balance and concentricity of the spinner and bearing itself. * Solid Copper triangle spinner with the new copper Malere button - 3.5oz (99g)* 1.97 inches ( 50mm) long x 1.25 inches (32mm) wide x .75 inches (19mm) thick with Malere buttons in place.* Stainless steel standard R188 Hybrid Ceramic - Si3N4 (1/2 inch (13mm) outer bore X 1/4 inch (6mm) inner bore x 3/16 inch (4.7mm) thick. 10 ball precision bearing* This model is not tumbled or bead blasted.
