About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX55-30
The AirTAC SAIJ160X55-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster, designed to precisely fine-tune end positions during commissioning. It provides a usable travel window of 25-55 mm, allowing you to dial back the nominal 55 mm stroke by up to 30 mm without adding external stops. In this bore size, it delivers a robust 10053 N pull force at 0.5 MPa and reaches speeds up to 30-500 mm/s.
This variant is built with an SUS420J2 stainless steel piston rod (code A) for enhanced durability against moisture and minor side loads. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed and DMSE electronic switches. It uses a PT tapered port thread and relies on standard variable air cushions at both ends to decelerate the load.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX55-30 Is Used
Machine Setup Tuning
Dial in the exact 25 to 55 mm stroke during initial commissioning to perfect pressing or clamping depth without machining custom spacers.
Product Changeover
Quickly adapt the cylinder's extended end-stop on a packaging line when switching to a different product thickness, saving setup time.
Short-Stroke Pressing
Leverage the 10053 N pull force for heavy-duty short-stroke forming operations where the exact bottom position must be micro-adjusted on the fly.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX55-30 the Right Cylinder?
Choose this 160 mm bore adjustable model when a process requires exact end-position tuning on a short-stroke, high-force actuator. If you need slightly less force, stepping down to the 125 mm bore yields 5734 N of pull at 0.5 MPa, whereas moving up to the 200 mm bore provides 15080 N. The rear adjuster screw acts purely as a mechanical stop to set the travel window; it is not a lock. If your application must hold a load securely without continuous live air pressure, select a SAIL air-released lock or BSAI clamp-lock cylinder instead. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR styles.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ160 Adjustable Cylinder SAIJ160AX55-30 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 30 mm. This creates a usable travel window of 25 to 55 mm, allowing you to set the exact retract position at commissioning without replacing the cylinder.
At a 0.5 MPa operating pressure, the SAIJ160X55-30 generates 10053 N of pull force and 14074 N of push force at 0.7 MPa, making it suitable for heavy-duty short-stroke tasks.
