LGS25 Stage Linear Guide Stage, 25mm height
The LGS25 is a compact screw-driven linear stage with a 25 mm low-profile design for reliable, configurable positioning in space-constrained systems. Available in lead screw or ball screw configurations, it supports flexible customization with multiple lead pitches, motor mounts, and encoder options.
Built with rigid linear guides and a lightweight aluminum base, the LGS25 delivers smooth, repeatable motion for automation, inspection, and precision positioning applications.
