Pneumatic Rotary Actuators for Industrial Automation

Available Motion Types and Actuator Families

• Single-rack rotary actuators – Standard 90°, 180°, and adjustable rotations for general-purpose motion.
• Dual-rack rotary actuators – Higher torque, balanced loading, and reduced lash for demanding loads.
• Multi-position rotary actuators – Three or more discrete rotary positions with hard stops.
• Indexing / stepping actuators – Accurate, repeatable incremental rotation for assembly, inspection, or test stations.
• High-speed pick-and-place actuators – Lightweight, fast-cycling units for rapid transfer and small-part handling.

Key Considerations When Specifying a Rotary Actuator

When we help select an actuator, we typically look at:

• Required rotation angle(s) and tolerance
• Available air pressure and torque requirements
• Inertia of the driven load and desired speed
• Stop method and energy absorption / cushioning
• Shaft style, keying, and mounting interface
• Environmental conditions and contamination
• Expected cycle rate and service life targets
• Maintenance, rebuild, and downtime constraints

Why OEMs and Integrators Choose Rotomation

• Tight mechanical tolerances for precise, repeatable shaft motion
• Configurable actuators and custom specials for unique applications
• Rugged, rebuildable designs with available replacement parts
• US-based engineering support and manufacturing in Daytona Beach, FL
• Long-term product continuity with ongoing design improvements
