Lower Cost Moving Magnet Designs

Typically an H2W Moving Magnet Actuator has precision bushings and shaft which cause the moving magnet design to be cost prohibitive. However not every customer requires a bushing with high tolerance precision, and thus H2W has the ability to modify the linear bearing systems of our voice coil designs to accommodate a lower cost bushing and shaft. The pictured actuator has a custom shaft and...
