Technical Specifications
Linear Actuator
A brand of SCREWTECH Automation
The KKR series integrates ball screw and linear guide, with rail widths 40–130 mm
Precision repeatability ±0.003 mm, max speed 1480 mm/s, offering a modular linear drive solution with fast installation, high rigidity, and compact size.
Core Features
Modular Design · Fast Installation
The U-rail integrates ball screw and linear guide, eliminating the tedious selection of separate guides and drives and greatly shortening assembly time.
Precision ±0.003 mm · High-Accuracy Drive
A high-precision ball screw drives the actuator, achieving ±0.003 mm repeatability for the high-accuracy needs of semiconductor and optical-inspection equipment.
U-Shaped Rail · Equal Load in 4 Directions
Gothic 45° four-point contact with FEA-optimized U-rail cross-section delivers equal load in all four directions and an optimal rigidity-to-weight ratio.
Six Sizes · Full-Scene Coverage
Six rail widths from 40 to 130 mm, leads 1–25 mm, strokes 100–1511 mm, with standard and light-load sliders, for light to heavy loads.
