About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX55-10S
The AirTAC SAIJ160X55-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position at commissioning. With a 55 mm nominal stroke and a 10 mm adjustment range, it provides a usable travel window of 45 to 55 mm without requiring external stops.
Equipped with a SUS304 stainless steel rod and a PT tapered port, this model delivers robust performance, offering a pull force of 9425 N at 0.5 MPa and reaching 18095 N at 0.9 MPa. The integrated magnet (-S) supports position sensing via AirTAC CMSE reed and DMSE electronic switches mounted in the dual-side sensor grooves.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX55-10S Is Used
Machine Setup Tuning
Dial in the exact 45 to 55 mm end position during commissioning without swapping cylinders or adding external mechanical stops.
Product Changeover
Quickly adjust the travel window on packaging lines when product sizes change, using the 10 mm rear stopper for rapid setup.
End-Position Calibration
Fine-tune the retract stroke on heavy machinery, leveraging the 18095 N push force at 0.9 MPa for precise heavy-duty positioning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX55-10S the Right Cylinder?
Choose this 160 mm bore when you need variable end-stops for product changeovers, stepping up from a 125 mm bore that yields 5734 N pull at 0.5 MPa. The 40 mm rod and M36x2 thread handle high side loads well, but for this 55 mm stroke, the load is safely contained. To match an ISO 15552 replacement, specify bore, 55 mm stroke, PT G3/4 port, and the -S magnet.
Remember that the rear adjuster acts only as a travel stop to set deceleration, not as a lock. The SAIJ does not hold loads without live air pressure; for secure load-holding without continuous air, use an external rod lock, or select the SAIL or BSAI 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.
