SUPER COLLIDER is a steel-core purpose-built for grip and control, designed around R188 fidget-spinner bearings. It gives you a more controlled way to support and work with a bearing during maintenance, inspection, and reassembly without turning a small job into a fight with loose parts and improvised tools.
Built for R188
Designed around the standard R188 bearing format commonly used in fidget spinners.
Controlled Bearing Maintenance
Keeps the bearing supported and properly positioned while you work, giving you more control over delicate bearing components.
