Linear Motion – DC Voice Coil Actuator Features Bearing System

Linear Motion - Voice Coil Motors with Bearings

Santa Clarita, CA –This linear motion moving coil voice coil actuator has a built-in bearing system in a compact package. Previously, customers’ would be required to either implement a bearing system through a stage, or make an accommodation on the envelope by trying to integrate a Moving Magnet Design. H2W has released NCC Actuators that are available from stock with strokes up to 5.2 inches, and longer strokes are available upon request. Although Voice Coil Actuators are traditionally shorter strokes, H2W now offers longer stroke actuators from stock. The moving coil style actuator is provided with supplied internal bushings and a hardened steel shaft.
