Cartesian Robot Rail Block

Repeated high-cycle movement in industrial environments leads to bearing fatigue, rail indentation, and eventual motion degradation. The contact surfaces inside Frigate’s rail blocks undergo cryogenic treatment followed by precision superfinishing, achieving Ra values below 0.1 µm. This reduces rolling resistance and minimizes Hertzian stress concentration on the bearing elements. The load zones are designed for uniform contact stress distribution, preventing localized wear and extending the fatigue life beyond 40 million linear meters under rated load conditions. 

Accessing linear rail blocks for maintenance within enclosed gantry configurations typically requires partial disassembly, resulting in extended downtime. Frigate’s design integrates a top-loaded service channel with lateral clamping, allowing block extraction and replacement without disturbing adjacent system components. Positioning repeatability is preserved through V-groove mechanical referencing, eliminating the need for recalibration after service. This feature enables predictive maintenance workflows where blocks can be cycled out during scheduled stops without affecting machine alignment.
