TECH TALK: Bimba PA Series NFPA Pneumatic Actuator


PA Series actuators are ideal for everyday pneumatic linear motion applications where versatility and modularity are valued. It’s an effective solution for a variety of industries such as:

  • Packaging
  • Food Processing
  • Material Handling
  • Industrial Automation Equipment

Unlike our existing NFPA series cylinders, the design includes an extruded aluminum body and die cast end caps, making the PA Series a lightweight, modern alternative to conventional tie rod actuators. These unique design features allow for easy cleaning and increased flexibility for mounting switches.

The PA is limited to five bore sizes, ranging from 1.50” to 4.00” with a maximum operating PSI of 250.

Sleeve nut construction and several bolt-on mounting options reduce complexity and increase flexibility for quick and easy installation.

PA Series actuators are equipped with an Auto Cushioning System. This uniquely designed internal air cushion auto-adapts to changing loads and conditions. This means cushion needle adjustment is not required, simplifying installation and setup, offering a fit-and-forget solution. Auto Cushioning is standard on the PA Series, which sets it apart from the TA and FM Series, which both have optional adjustable or fixed cushions.

Also included as an option is the Ecology Piston Seal. The Ecology Seal is an engineered piston seal designed to absorb energy and reduce vibration in high speed applications. When used in conjunction with the Auto Cushion, the Ecology Piston Seal enhances conventional cushioning technology to improve end of stroke deceleration and energy absorption.
