About Linear Thrusters

Linear thrusters use double-acting pneumatic, hydraulic, or electrohydraulic cylinders mated to plates and shafts to provide cyclical linear motion. They are used in conveying, positioning and inspection systems. The integral stages of linear thrusters are mounted vertically or horizontally and include features such as position switches, end stops and cushions, and corrosion resistant coatings and treatments. There are several common drive configurations. ACME screws are square-topped and have a very specific thread geometry that directly contacts the nut and provides linear motion through direct sliding friction between the nut and lead screw. Ball screws are lead screw and ball nut combinations in which the balls in the nut circulate when in motion. Belt drives connect the motor to the actuator with a belt. By contrast, geared drives connect the motor to the actuator through a set of gears. Others specialized and proprietary drive configurations for linear thrusters are also available.

Products & Services Related to Linear Thrusters

Air Cylinders

Air cylinders are pneumatic linear actuators that are driven by a pressure differential in the cylinder's chambers. They may be single-acting (with a spring return) or double-acting.

Hydraulic Cylinders

Hydraulic cylinders are actuation devices that utilize pressurized hydraulic fluid to produce linear motion and force.

Linear Actuators

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.

Rodless Cylinders

Rodless cylinders are linear devices that use pressurized fluid to move a load within many power transfer operations.
