Features

The Series 8000 is driven by a high-starting torque motor connected to a drive screw through gearing. When the motor rotates the drive screw, the mating drive nut and attached extension rod move axially. The gear-driven position limit switch interrupts power to the motor upon completion of stroke. If during actuator travel some external obstacle prevents the extension rod from moving, the thrust limit switch will interrupt power to the motor.

The 8400 and 8500 Series Actuators contain an additional spring assembly to protect the actuator drive components from shock loads. When compressed, the inherent spring load will provide automatic compensation for wear, temperature change, or material compression.
