Overview
The ZOLIX RoS Series Industrial Linear Actuator is a high-performance, single-axis motorized translation stage engineered for precision motion control in industrial automation, optical alignment systems, and integrated laboratory instrumentation. Unlike piezoelectric or belt-driven stages, the RoS series employs a robust rolled ball screw transmission coupled with square-section linear guideways—delivering high rigidity, load-bearing stability, and deterministic kinematic behavior under continuous operation. Its mechanical architecture follows classical Couette-type sliding principles adapted for macro-scale linear displacement, where rotational input from a stepper or servo motor is converted into precise axial translation via controlled screw-nut engagement. Designed explicitly for OEM integration and modular system building, the RoS platform serves as a foundational motion component in applications requiring repeatable positioning across extended travel ranges—from compact optical breadboard setups to large-scale industrial inspection gantries.
Key Features
- Precision rolled ball screw drive with standardized leads (4 mm, 5 mm, or 10 mm), enabling optimized trade-offs between speed, resolution, and torque transmission
- Square-section linear rail system with configurable carriage layout (single or dual slider), ensuring low-friction guidance and high moment-load resistance
- Lightweight aluminum alloy housing with CNC-machined structural geometry—optimized for thermal stability and minimal inertia during acceleration/deceleration cycles
- Modular motor interface supporting NEMA 17/23 stepper motors or compatible servo units; quick-release mounting facilitates field maintenance and actuator retrofitting
- Factory-calibrated repeatability of ±0.02 mm (for models up to 600 mm travel) and ±0.05 mm (800–1000 mm variants), verified per ISO 230-2 Annex B methodology
- Integrated mechanical limit switches and optional home-sensor compatibility for deterministic homing in closed-loop control architectures
Sample Compatibility & Compliance
The RoS series is compatible with standard optical table mounting patterns (M6 threaded holes on 25 mm grid) and integrates seamlessly with TMC SC300-series motion controllers, third-party PLCs, and LabVIEW-based DAQ environments. All mechanical components comply with RoHS Directive 2011/65/EU and meet CE conformity requirements for machinery safety (EN ISO 12100). While not certified for cleanroom Class 100 operation, the stage’s sealed guideway design minimizes particle generation and supports use in ISO Class 8 environments typical of semiconductor metrology labs and laser processing workcells. No vacuum-rated variants are available; ambient operation only (5–40 °C, <80% RH non-condensing).
Software & Data Management
The RoS stage operates as a position-controlled peripheral and does not include embedded firmware or proprietary GUI software. It interfaces via standard step/direction TTL signals or analog ±10 V velocity commands, allowing full compatibility with industry-standard motion control ecosystems—including NI Motion, Galil DMC, and Beckhoff TwinCAT. When paired with the optional SC300 controller, users gain access to real-time trajectory profiling, multi-axis synchronization, and audit-trail-capable parameter logging aligned with GLP-compliant documentation practices. Firmware updates (if applicable to controller hardware) adhere to IEC 62443-3-3 security requirements for industrial control systems.
Applications
- Automated optical alignment in fiber coupling stations and free-space interferometer assembly
- Positioning module in AOI (automated optical inspection) systems for PCB and display panel testing
- Linear axis in custom-built spectroscopic sample scanners and monochromator slit drives
- Stage subsystem in laser material processing platforms requiring micron-level registration over 1 m travel
- OEM integration into biotech fluidic handling systems where programmable reagent dispensing trajectories are defined by absolute position referencing
FAQ
Is the RoS series suitable for vacuum environments?
No—this product is rated for ambient atmospheric operation only and lacks vacuum-compatible lubricants or outgassing-certified materials.
Can I use my existing stepper driver with the RoS stage?
Yes—the stage accepts standard 5 V TTL step/direction inputs and is electrically agnostic to driver brand or microstepping configuration.
What is the maximum recommended payload for dynamic operation at 500 mm/s?
For RoSxx-1000 models operating at top speed, the horizontal dynamic load limit is 10 kg; exceeding this may compromise repeatability and accelerate guideway wear.
Does ZOLIX provide SDKs or API libraries for custom software integration?
No native SDK is supplied; however, SC300 controller communication uses ASCII-based serial protocol documented in the publicly available SC300 Programmer’s Manual (Rev. 4.2+).
Are calibration certificates traceable to NIST or CNAS standards included?
Factory repeatability verification reports are provided with each unit, but formal metrological certification (e.g., ISO/IEC 17025) requires third-party calibration service engagement.
