Introduction
The HASF Solid series (HASF11, HASF14, HASF17, HASF20, HASF25) is a harmonic servo rotary actuator designed for precision torque transmission in compact assemblies. This integrated-flange version adds a disc-shaped flange for face-contact mounting and includes a Tamagawa multi-turn absolute encoder (single-turn 23-bit, multi-turn 16-bit). Rated torque ranges from 4 to 133 N·m depending on model and reduction ratio.

Key features

• Integrated disc-shaped flange for secure face-contact mounting and improved axial/radial support.
• Compatibility with Tamagawa multi-turn absolute encoder for accurate position feedback.
• Face-mount simplifies assembly by reducing shaft-alignment requirements and lowering calibration effort.
• Modular design: individual modules removable by loosening flange bolts to simplify maintenance and reduce downtime.

Technical specifications (key parameters)

• Series & models: HASF11, HASF14, HASF17, HASF20, HASF25.
• Rated torque: approx. 4–133 N·m (model & reduction dependent). Peak torque: up to ~217 N·m.
• Encoder: Tamagawa multi-turn absolute — single-turn 23-bit, multi-turn 16-bit.
• Typical reduction ratios: 51, 81, 101, 121, 161 (model dependent).
• Rated / max speed: model/ratio dependent (typ. rated up to ~69 RPM, max up to ~118 RPM).
• Mass (without/with brake): from ~1.17 kg / 1.36 kg (HASF11) to ~3.6 kg / 4.2 kg (HASF25).
• Hollow shaft diameters (examples): Ø9, Ø10, Ø13.5, Ø16.5, Ø17 mm according to model.

Applications

• Robotics and cobot joints requiring compact, high-precision torque transmission.
• Automated assembly, precision indexing tables and handling equipment.
• Machine tools, inspection systems and test rigs where face mounting is preferred or required.

Ordering & options

• Available with/without brake; multiple reduction ratios and hollow-shaft sizes per model.
• Electrical configuration reference example: AC-220V; motor electrical parameters and pole counts vary by model.
