Lead Screw Linear Actuator Assemblies – Captive & Non-Captive

Lead Screw Linear Actuator Assemblies – Captive & Non-Captive

Lead screw linear actuator assemblies from PBC Linear are engineered to deliver high torque, precision positioning, and long service life across a wide range of motion control applications. Designed for reliability and performance, these actuators are available in both captive and non-captive configurations, giving engineers flexibility to optimize system layout and footprint. The non-captive design is ideal for space-saving applications, allowing for a more compact overall assembly while maintaining high thrust output and positioning accuracy. Captive configurations provide traditional integrated motion control for straightforward installation and dependable performance.

Each actuator incorporates angular contact bearings within the motor housing to fully support the lead screw. Larger, preloaded bearings increase thrust capacity, improve durability, minimize runout, and eliminate axial play—ensuring consistent precision and repeatability over time. Optional Smart Motor Technology delivers up to 50% more torque, significantly reducing cycle times and improving overall machine efficiency.
