Spin Testing Systems

Evaluate the strength, resistance to fatigue, and burst acceleration resistance of materials by subjecting them to centrifugal force through rotation of the component

BTI Spinner Machine

Balance Technology Spin Testing Equipment

Spin test systems are used to test the strength and durability of rotating components by subjecting them to centrifugal force. These test stands are specifically designed for the development, production, and quality assurance of a variety of items, including electric vehicle components, such as EV rotors. Our spin test systems can be customized to meet desired product specifications.


High Speed Part Chuck

The component to be spun is held during the spin process by a spring-loaded, pneumatically released part chuck.


Rotor Load & Lift Mechanism

A custom radial bearing is mounted to a servo-electric actuator that raises the loaded component into the spin processing position.


Sound & Safety Enclosure

Each spinner comes equipped with a fixed enclosure mounted at the base, encasing the entire machine. Rear service doors allow access for maintenance and are safety interlocked. A pneumatically actuated vertical access door allows for part loading and unloading by a robot or operator.
