Products/Services for Bear Linear Actuator

  • Linear Actuators-Image
    Linear Actuators - (728 companies)
    Electric linear actuators have an output rod that provides linear motion via a motor driven ball screw, lead screw or ACME screw assembly. The actuator's load is attached to the end of a screw or rod and is often unsupported. Linear actuators...
