OTC DAIHEN A2PB Series Horizontal Rotary Servo Positioner System
The OTC DAIHEN A2PB Series (A2PB252-E, A2PB502-E, A2PB1002-E) represents industrial durability in horizontal rotary positioning. These vertical-axis turn-tables are engineered to index workpieces rapidly between operator loading stations and robotic welding zones, or to perform synchronized continuous rotation during arc welding. Featuring zero-backlash reduction gears and direct AC servo drive integration, the A2PB series delivers an outstanding Tool Center Point repeatability of ±0.05 mm (measured at R=250 mm). It serves as the standard foundational building block for automated dual-station welding cells in automotive parts, motorcycle frames, and hydraulic cylinder manufacturing.

🔧 Engineering & Operational Guide
- Table Flatness & Fixturing: Ensure that custom holding fixtures bolted to the A2PB rotary table surface are machined flat. Uneven fixture mounting bolts can distort the table surface and induce stress on the internal spindle bearings.
- Emergency Stop Braking: The internal electromagnetic brake is designed to hold position when power is removed. Do not use emergency stop braking repeatedly during high-speed rotation of max-payload fixtures, as this accelerates brake disc wear.
- Cable Commutator (Slip Ring): If your holding fixture requires pneumatic clamping or electrical sensor signals on the rotating table, install an OTC rotary joint (slip ring) through the hollow center shaft to prevent hose tangling.
