Moving Magnet Non-Comm DC Voice Coil Linear Actuator, NCM04-35-250-2LVE
This moving magnet actuator (NCM04-35-250-2LVE) comes supplied with an integrated vacuum compatible recirculating ball bushing linear bearing, which has been selected especially for the usage with this actuator. This actuator has been manufactured using low-outgassing materials as selected by NASA in order to make this actuator vacuum compatible.

Moving magnet actuators come standard with a linear bearing system. If you would like to see these actuators without a built-in bearing system please look at our moving coil models. Or if you would like to see how we have integrated our moving magnet voice coils into closed loop positioning stages please look at our voice coil positioning stages.

To determine your motion profile needs, use our linear motion calculator.
