SAK Series Electric Actuator (KK Module / Steel Base Precision Module)



The SAK Series KK Module (Steel Base Precision Module) delivers exceptional structural rigidity, high-precision positioning, and space-saving modular integration for demanding single-axis and multi-axis industrial automation systems.

Designed with a highly integrated U-shaped steel base that unifies the precision ball screw drive and linear guide track into a single compact structure, the SAK Series eliminates multi-component alignment complexities while maximizing spatial efficiency. Developed using Finite Element Analysis (FEA) for structural optimization, the high-rigidity steel channel provides maximum resistance against bending and torsional deformation under heavy dynamic forces. Featuring a 45-degree Gothic arch contact groove design, the module achieves equal load capacity in all four directions (radial, reverse-radial, and lateral). Available in multiple standardized frame sizes (SAK50, SAK60, SAK86, SAK100), it serves as an ideal motion platform for automated optical inspection (AOI), semiconductor positioning, PCB assembly, medical diagnostics, and high-precision Cartesian robotic systems.

Key Features & Advantages

  • Integrated U-Shaped Steel Base: Combines the linear guide track and structural chassis into a single steel profile, significantly reducing cross-sectional height and overall footprint.
  • 4-Way Equal Load Geometry: 45-degree Gothic arch groove contact arrangement ensures uniform load-bearing capacity across radial, reverse-radial, and lateral orientations.
  • FEA-Optimized High Rigidity: Engineered via Finite Element Analysis to deliver maximum structural stiffness with optimized total weight.
  • Precision Ball Screw Drive: Delivers superior micro-positioning accuracy, low axial play, and smooth motion transmission.
  • Modular Installation Efficiency: Replaces traditional multi-part linear guide and screw assemblies to simplify machine design, speed up installation, and lower maintenance overhead.

The SAK Series Electric Actuator provides an adaptable, cost-effective motion control solution for production engineers and builders seeking uncompromised accuracy and long-term reliability.
