About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-50S
The AirTAC SAIJ100X160-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 110 to 160 mm usable travel window. Delivering 5497 N of push force at 0.7 MPa, it is built with a SUS304 stainless steel rod and includes a magnet for position sensing. The PT tapered ports and extruded aluminum barrel ensure robust pneumatic performance.
This adjustable-stroke design allows you to fine-tune the retract end position at commissioning without adding external stops. The rear screw acts purely as a travel stop and does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-50S Is Used
Product Changeovers
Dial in the 110 to 160 mm travel window during format changes on packaging lines without swapping out the entire actuator.
End-Stop Tuning
Fine-tune the retract position during machine commissioning to achieve precise seating of heavy 100 mm bore tooling.
Assembly Pressing
Leverage 5497 N of force at 0.7 MPa to press components securely while adjusting the stroke to accommodate varying part heights.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-50S the Right Cylinder?
Choose this 100 mm bore cylinder when an 80 mm bore (providing 3518 N push at 0.7 MPa) cannot meet your thrust requirements, but you want to avoid stepping up to a 125 mm size. The 50 mm adjustment range is ideal for product-size changeovers, letting you dial in the exact end-stop on the fly. To replace an ISO 15552 cylinder, match the 100 mm bore, 160 mm stroke, G1/2 port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). The integrated magnet supports AirTAC CMSE reed and DMSE electronic sensors. Since the stroke is under 300 mm, side-load risks are moderate, but external guides are still recommended for heavy lateral loads.
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 SAIJ100 Adjustable Cylinder SAIJ100BX160-50S FAQ
At 0.7 MPa operating pressure, this 100 mm bore cylinder provides 5497 N of push force and 5497 N of pull force. At 0.5 MPa, the push force is 3927 N.
The rear adjuster screw allows you to trim the effective stroke by up to 50 mm, creating a usable travel window of 110 to 160 mm. It functions as a mechanical stop and does not lock the load without continuous air pressure.
