About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X120-30S
The AirTAC SAIJ160X120-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 90 to 120 mm. It delivers substantial thrust, generating 14074 N of push force at 0.7 MPa, making it suitable for heavy-duty operations. The integrated magnet supports position sensing via AirTAC CMSE reed and DMSE electronic switches.
This model features a robust 40 mm carbon steel rod and a PT tapered port. Unlike fixed-stroke SAI variants, the rear stopper screw allows precise end-position tuning during commissioning without adding external stops. The adjuster acts solely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X120-30S Is Used
Heavy-Duty Press Fit
Dial in the exact 90 to 120 mm insertion depth during press-fit assembly to accommodate material tolerances without changing tooling.
Product Changeover
Quickly adjust the end stop for varying package sizes on a packaging line, utilizing the 30 mm trim range to handle different product dimensions.
Machine Setup
Fine-tune the rear stroke position during initial machine commissioning to perfectly align heavy workpieces before final locking.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X120-30S the Right Cylinder?
Choose this 160 mm bore when an application demands higher force than the 125 mm bore, which offers 8590 N push at 0.5 MPa, but does not require the extreme output of the 200 mm version. The adjustable 90-120 mm travel window is perfect for product-size changeovers on a line. For load-holding without continuous air pressure, consider the SAIL or BSAI series, as the SAIJ adjuster is not a locking mechanism. To match this ISO 15552 interchangeable cylinder, specify the 160 mm bore, 120 mm stroke, 30 mm adjustment, PT port, and the -S magnet 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 SAIJ160 Adjustable Cylinder SAIJ160X120-30S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a push force of 14074 N and a pull force of 9425 N. It can reach a maximum push force of 10053 N at 0.5 MPa.
The rear adjuster allows you to shorten the effective travel by up to 30 mm, creating a usable stroke window of 90 to 120 mm. This stopper sets the end position but does not lock the load without live air pressure.
