About the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX180-30
The AirTAC SAIJ50X180-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 150-180mm usable travel window from its 180mm nominal stroke. Delivering 982N of push force at 0.5MPa, it handles mid-range automation tasks efficiently. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE and DMSE switches.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The rear adjuster acts purely as a mechanical stop to dial in the end position during commissioning without adding external stops. It is not a locking device, so load-holding without live air requires a SAIL or BSAI cylinder.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX180-30 Is Used
Variable End-Stop Tuning
Dial in the exact 150 to 180mm travel distance during machine setup without swapping cylinders or adding external stopper blocks.
Product Changeover Lines
Quickly adjust the retract end-position to accommodate varying package sizes on a single conveyor handling system.
Corrosive Environments
Leverage the SUS304 stainless steel rod for reliable mid-force clamping in washdown or chemical exposure areas.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX180-30 the Right Cylinder?
Choose this 50mm bore when 40mm (628N at 0.5MPa) is insufficient but 63mm (1559N) is oversized. The 30mm adjustment range is ideal for product changeovers where exact end-of-stroke positioning varies. For strokes of 180mm, the 16mm rod and M12x1.25 thread handle moderate side loads, though longer unsupported strokes still need an external guide. To match this ISO 15552 cylinder, specify 50mm bore, 180mm stroke, 30mm adjustment, PT G1/4 ports, and the SUS304 (B) rod option.
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 SAIJ50 Adjustable Cylinder SAIJ50BX180-30 FAQ
It provides 982N push and 825N pull force at 0.5MPa, reaching 1374N push at 0.7MPa. The operational speed range is 30-800mm/s.
The rear adjuster screw lets you shorten the effective travel from 180mm down to 150mm. It functions as a travel stop for fine-tuning, not a lock, so it will not hold a load without live air pressure.
