Screw spindle linear module DSLM

guidesingle-axis

Product Overview
DINGS' DSLM series in NEMA Size 23 (57 mm) is a linear slide module designed for high linear speed and precise positioning. The module uses a spline slide rail as the linear guide, enabling long travel up to 900 mm and controlled slider offset. The DSLM series features a Teflon coating for extended service life and a fixed half-nut drive structure for stable actuation.

Note
Because the DSLM module uses pure sliding friction, consult standard linear thrust force data and allow a selection margin of 1–2 kg to ensure reliable operation.
