About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX550-30S
The AirTAC SAIJ160X550-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 520 to 550 mm. Delivering a substantial 18095 N pull force at 0.9 MPa, this 160 mm bore unit handles heavy-duty positioning. It features a SUS304 stainless steel piston rod for superior corrosion resistance and includes a magnet for solid-state DMSE or reed CMSE sensor integration.
Unlike a fixed-stroke SAI, the external rear stopper allows you to fine-tune the retract end-position at commissioning without adding external stops. The PT tapered ports and integrated variable air cushions manage deceleration, but remember the adjuster is a travel stop, not a lock; for load-holding without live air, consider an SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX550-30S Is Used
Heavy Press Tuning
Dial in the exact 520-550 mm retract distance during machine setup to accommodate varying material thicknesses without physical hardware changes.
Product Changeover Stops
Adjust the end-stop on the fly for different package sizes on a heavy-duty packaging line, utilizing the 30 mm trim range.
Large Assembly Positioning
Move substantial jigs with 18095 N of pull force at 0.9 MPa, relying on the rear screw to set the final precise resting position.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX550-30S the Right Cylinder?
Choose this 160 mm bore when your application requires high force, as it provides 9425 N pull at 0.5 MPa. If you need less force, stepping down to a 100 mm bore yields 3681 N pull at 0.5 MPa. The adjustable stroke is selected for machine changeover flexibility, allowing up to 30 mm of end-trim without swapping cylinders. Since the 550 mm stroke is long, the 40 mm rod diameter requires an external guide to prevent excessive side-load damage.
For a true ISO 15552 dimensional replacement, match the 160 mm bore, 550 mm stroke, 30 mm adjustment, PT ports, and the -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets found on some other series.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ160BX550-30S FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder generates 18095 N of pull force and 28274 N of push force. At 0.5 MPa, it provides 9425 N pull and 10053 N push.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from 550 mm down to 520 mm. It is a travel-limiting stop for end-position tuning, not a lock, and it will not hold the load without continuous air pressure.
