Rack And Pinion Aluminum Single Acting Pneumatic Actuator

1 – Hard Anodized Barrel/ Body to Protect from Hazardous atmosphere & corrosion, which enhances the life of the actuator.

2 – Mounting Standard Pinion Top (As Per Namur Standard) The pinion (shaft) topis drilled and slotted for easy assembling of switches, positioners, and other accessories.

3 – Adjusting Bolt Adjusting Bolts for 0° – 90° ± 5% Over Travel.

4 – ISO – 5211 Standard Mounting for Valve (An International Standard) Double bottom drilling for the actuator to valve Assembling & centering. Designed for strength and easy mounting or interchangeability.

5 – ISO – 5211 Standard Pinion Bottom (An International Standard) Bottom of the pinion (Shaft) a female key, double square-hole for assembling on valves with square key stem and in line or turned to 45°. Designed for strength and sure-fix with stem.

6 – Sliding Skates The innovation for replaceable sliding skates, between Pistons (Racks) and the internal bore surface of the Actuator, just to avoid metal contact, which enhances the Actuator's life.

7 – Compact Design “aira” Actuators are designed as compact acting which offers high torque values. Internal sliding surface, machined and anodized for minimum friction and long life of the actuator

This single-acting pneumatic rotary actuator has one central skewed shaft (Pinion) and two spring-connected pistons with skew ends (Rack). When pressurized air enters in an actuator, the pistons move away from the central shaft, and the shaft gets rotational movement because shaft skews (Pinion) & piston skews (Rack) are connected. When the flow of pressurized air, the springs on the other side of the shaft send back pistons to their original position, and this time also Pinion gets rotational movement because of Racks.

In this one cycle of pistons’ movement, the shaft gets two rotational movements in only a one-time entrance of pneumatic air. So it is called a single-acting pneumatic rotary actuator.

Where to Use a Single-Acting Pneumatic Actuator?

This single-acting pneumatic actuator provides rotary motion and this product is available for 90° or 180° rotation. So it is useful to operate valves, automatic manufacturing, clamping work, etc. These pneumatic actuators allow hands-free operation so there is no requirement for the manual operator and work smoothly even in a hazardous environment. This is also useful for flammable conditions as it provides a spark-free action.
