Physical Characteristics & Weight Efficiency

The CDRBS series offers a significantly reduced footprint and mass compared to conventional rotary actuators, facilitating faster movement and reduced inertia in robotic arms and pick-and-place systems.

Weight Reduction: Achieve up to 48% reduction in weight compared to previous designs (e.g., Size 20 weight reduced from 222g to 115g).
Total Length Reduction: Compact body design reduces overall length by up to 44% in select models.
Standard Weights (g):
- ø10: 39g | ø15: 62g | ø20: 115g | ø30: 216g | ø40: 380g,.

Mounting and Integration

Interchangeability: Mounting hole patterns and shaft dimensions are maintained for backwards compatibility with existing industrial standards.
Standard Shaft: Equipped with a single-shaft configuration.
Sensor Compatibility: Specifically designed for use with D-M9 series auto-switches (2-wire D-M9B or 3-wire NPN D-M9N) for precise position feedback,.
Angle Tolerances:
- 90°: +4° / 0° (sizes 20, 30, 40),.
- 180°: +4° / 0° (sizes 20, 30, 40),.
- 270°: +4° / 0° (sizes 20, 30, 40).

Operational Safety Notes

Low-Speed Control: Operation slower than 0.5s/90° may result in stick-slip phenomena; always operate within the specified speed range for consistent performance,.
Size 10 Start-up: For Bore Size 10 to reach maximum speed (0.03s/90°), a minimum operating pressure of 0.35 MPa is required
