Overview
The Bimba PT-098090-C1GM is a double-acting pneumatic rotary actuator part of the proven Pneu-Turn series. This compact rack-and-pinion design delivers consistent torque output and is widely used in valve control, damper drives, and automated positioning applications across food, beverage, packaging, and industrial automation systems.
Key Features
- Double-acting construction with single-shaft design for reliable bidirectional rotation
- Rack-and-pinion mechanism delivers smooth, repeatable 90° rotation
- Cushion ports (both sides) reduce shock and extend component life
- Anti-backlash rack minimizes positioning error and hysteresis
- Magnetic position sensing option available for feedback integration
- Stainless steel construction (304 cylinder body, 303 shaft) resists corrosion in washdown environments
