AFC90 Series – Single Axis Linear Motor Stage
The Akribis AFC90 Series is a compact, high-precision direct drive linear module featuring dual self-lubricating linear guides, integrated encoder feedback and travel lengths up to 500 mm. It offers repeatability down to ±0.5 μm and is suitable for precision positioning, optical alignment and high-speed automation applications.
AFC90 Series Single-Axis Linear Motor Stage
The AFC90 Series is a compact, high-precision single-axis positioning stage designed around direct drive linear motor technology. It integrates a linear motor, dual linear guides, high-resolution optical encoder feedback and a rigid aluminium housing into a complete motion module.
By removing mechanical transmission components such as ball screws, belts and couplings, the direct drive system provides smooth motion, rapid response and precise positioning without backlash. This also reduces mechanical wear and helps minimise maintenance requirements in demanding automation systems.
The AFC90 Series delivers continuous force ratings from 20 N to 34 N and peak force ratings from 55 N to 91 N. Encoder resolution is available down to 0.05 μm, with repeatability down to ±0.5 μm for travel lengths up to 50 mm and ±1 μm for longer travel configurations. Stroke lengths of up to 500 mm are available.
Dual self-lubricating linear guides provide stable and accurate linear motion while supporting long-term industrial operation. The compact construction and flexible installation arrangement make the stage suitable for machines where space, positioning accuracy and dynamic performance are important.
The AFC90 can be installed as an individual single-axis stage or combined with another module to create a compact XY positioning system.
