OTC DAIHEN 1-Axis positioner

OTC Daihen 1-Axis positioners (250 – 1,000 kg payload) add synchronized rotational motion for improved robot welding reach, precision, and cable routing.

Product Specification

External Rotating Axis OTC DAIHEN® Positioners

WHAT ARE 1-AXIS POSITIONERS?

Coordinated Synchro-Motion • Full Robot Integration

The OTC Daihen 1-Axis Positioner (Headstock / Tilt-Turn) systems operate as an external rotating axis that can be fully synchronized with your welding robot. They drastically improve joint accessibility and welding precision by dynamically rotating the workpiece to the optimal position during the active production cycle.

Key Models & Technical Specifications

Model	Payload Capacity	Rotational Speed	Allowable Torque	Position Repeatability	Dead Weight
1PB250	250 kg	150°/s (2.6 rad/s)	206 N·m	±0.1 mm @ R=300 mm	110 kg
1PB500	500 kg	120°/s (2.1 rad/s)	490 N·m	±0.1 mm @ R=300 mm	170 kg
1PB1000	1,000 kg	72°/s (1.3 rad/s)	1,078 N·m	±0.1 mm @ R=300 mm	220 kg

Note: Position repeatability is calculated and verified at a standard continuous radius (R) of 300 mm from the rotation center.

Common Features

• Integrated 500 A welding terminal: Safely routes high-current welding grounding cables directly through the center faceplate.
• Tapping points on housing: Provides highly versatile and adaptive structural mounting options for varied fixtures.
• Center-hole cable routing: Hollow shaft construction ensures completely clean, obstruction-free pneumatic and electric wire routing.
• Controlled via robot pendant: Governed natively via the primary robot teach pendant, enabling absolute multi-axis Synchro-Motion control.

Target Applications

• Highly optimized for heavy welded sub-assemblies including structural frames, pressure tanks, automotive components, and complex industrial metalwork.
• Utilizes tilt-turn motion models to provide superior torch clearance and a consistently optimal downhill welding orientation.

Why Choose OTC Positioners?

✓ Maximizes the active working envelope and physical reach of the robotic manipulator.
✓ Enhances workplace safety and operational ergonomics by heavily reducing manual component manipulation.
