Linear Motion Slide – LM™
Dover Motion’s LM™ series linear slide is one of our most popular single axis positioning stages. It incorporates precision crossed roller ways resulting in a high load capacity (up to 175 kilograms) and stiffness as compared to ball way style bearings.
Description of the LM™ Linear Slide
The LM™ series linear slide incorporates a lead screw for high accuracy and low cost, and comes standard with a 200-count stepper motor. For higher resolution motion, an upgrade to a 400-step-per-revolution stepper motor or servo motor is available.
We also offer an optional rotary encoder to be mounted to the lead screw shaft and provide position feedback with 2000- or 4000-count resolution. The encoder feedback provides the controller with position information to avoid open loop stepping. A manual knob to move the stage when powered off comes standard on LM™ series linear slides, along with end of travel limit switches and D-sub style electrical connectors.
The LM™ series electric linear slide positioning stage has different metric and English lead screw pitch choices depending on application resolution and speed requirements.
Applications for Linear Slides
LM™ series linear slides are used in many applications where stepping or scanning of a part is required. Our customers are using LM™ series to move parts in laser machining equipment, or to scan the surface of magnetic media.
