Overview
DINGS' DSLM Series in NEMA Size 17 (42 mm) is a compact linear module offering high linear speed and precise positioning. The module uses a spline slide rail as the linear guide, supports strokes up to 900 mm, features a Teflon coating for extended service life, and employs a fixed half-nut drive for a stable structure.
