YIDI MOTION, a manufacturer of linear motion components and positioning solutions, today introduced the EB double-shaft series screw drive linear module. Engineered as a compact, cost-effective positioning stage, the EB combines a C7 grade ball screw with dual parallel guide shafts to deliver ±0.03 mm repeat positioning accuracy in a space-saving aluminum extrusion platform.
Designed for Compact Automation
The EB module is built around two polished bearing steel guide shafts flanking a central precision ball screw. This dual-shaft architecture eliminates longitudinal clearance, providing smoother operation, higher stiffness, and greater load capacity than single-shaft alternatives. The unit ships with a black NEMA 23 (57 frame) stepper motor as standard, with three ball screw lead options — 1204, 1605, and 1610 — to match speed, thrust, and resolution requirements.
Key Features and Benefits
· C7 grade ball screw with flange nut, available in 1204, 1605, and 1610 configurations; dust-proof and rust-resistant for reliable long-term use.
· Dual-shaft linear guide design removes axial play for consistent, repeatable motion and higher effective load capacity.
· Bearing steel guide shafts and rigid aluminum extrusion housing ensure durable, quiet, and smooth travel up to 300 mm/s.
· Flexible mounting system: side-mounted M4 nuts can be positioned at any location along the extrusion, while bottom M6 movable nuts simplify limit switch installation.
· Easy to install and commission, with a manufacturer-backed warranty and fast shipping from YIDI MOTION.
