Technical Information

Product Details

High-precision ACME lead screw linear module. Compact, cost-effective linear motion stage for light-duty automation, medical positioning, and lab equipment. Custom strokes available.

The ACME lead screw linear module is a compact, cost-effective linear positioning stage designed for smooth, precise linear motion in light-to-medium duty automation systems. Featuring a high-grade precision ACME trapezoidal lead screw integrated with an extruded aluminum base and smooth linear guide rails, this module provides high mechanical rigidity and reliable positioning performance.

Engineered with self-locking capabilities and anti-backlash nut options, this ACME linear actuator stage eliminates back-driving under vertical loads, making it an ideal choice for medical diagnostics, laboratory automation, and precision adjustment mechanisms.

Key Features & Advantages

Self-Locking Safety: Trapezoidal ACME screw profile prevents back-driving under static loads without needing extra power brakes.
Cost-Effective Precision: Delivers high positioning accuracy and smooth travel at an economical price point for volume machinery.
Compact Extruded Aluminum Profile: Lightweight yet durable structure optimizes machine space and simplifies multi-axis mounting.
Quiet & Smooth Operation: Self-lubricating nut options ensure whisper-quiet motion with minimal maintenance required.
