OTC DAIHEN 1PB500 – Robust 1-Axis Positioner for Medium to Heavy Workpieces

High-Torque Rotational Precision • Coordinated Synchro-Motion

The OTC DAIHEN 1PB500 is a high-performance 1-axis rotary positioner designed to handle medium to heavy-duty workpieces with exceptional rotational precision. Engineered to safely carry dynamic loads up to 500 kg, this positioner delivers highly fluid and synchronized movement for optimized robotic welding accessibility and joint alignment accuracy.

Key Features

• Large Payload Capacity: Rugged design supports medium-heavy industrial parts up to 500 kg.
• Controlled Rotation: Maintains smooth, controlled operation speeds of 120°/s (2.1 rad/s).
• High Torque Handling: Robust internal gearbox withstands rotational twisting forces up to 490 N·m.
• Precision Repeatability: Limits path tolerance to an ultra-tight ±0.1 mm within a 300 mm radius.
• Built-in Cable Routing: Features a hollow center shaft with an integrated 500 A heavy-duty welding terminal.
