US8RT-05-0400A-O8-N-C-X-MR-GR THK Universal Series electric linear actuator (US8RT family)

This unit is a THK Universal Series electric linear actuator (US8RT family) — a robust ball-screw driven actuator designed for general purpose precision linear motion in industrial machinery.

🛠 Key Features

• Series: THK Universal Series Electric Actuator — part of THK’s general-purpose linear actuator lineup.

• Model Family: US8RT — size category around the 8 mm shaft/rail class (medium duty).

• Lead: 05 — 5 mm ball screw lead (fine lead for better control).

• Stroke: 0400A — 400 mm stroke between mechanical stoppers.

• Motor / With or Without: Likely with motor option prepared (O8 could indicate motor bracket option).

• Options:

  • N, C, X — internal configuration / mounting details (THK option codes).

  • MR — Motor right-wrap orientation.

  • GR — Gray end cap / housing color.

📊 Functional Highlights

• Compact, robust electric actuator with integrated ball screw and LM guide.

• High rigidity and speed: Suitable for precision linear motion with moderate loads.

• Motor wrap options (e.g., MR or ML) allow flexible cable routing and installation.

• Universal mounting styles — top base or under base mounting adaptability.

• Wide applicability — used in automated machinery, conveyors, indexing tables, and positioning systems.

Note: THK part codes for electric actuators encode a combination of lead, stroke, motor type, sensor options, mounting, and cover color. Without the full THK catalog for this exact combination, the above is a close match based on US8RT series configuration standards.
