About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-20
The AirTAC SAIJ100X160-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 140-160 mm usable travel window, letting you dial back the 160 mm nominal stroke by up to 20 mm. Delivering 3927 N of push force at 0.5 MPa, it handles heavy positioning tasks with precision.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and includes PT tapered ports. The extruded aluminum barrel integrates dual sensor grooves, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-20 Is Used
Machine Changeovers
Fine-tune the 140-160 mm travel window during product size transitions to set exact end positions without swapping cylinders.
Variable End-Stop Setup
Dial in the retract stop at machine commissioning to compensate for mechanical tolerances and achieve precise positioning.
Heavy Assembly Pressing
Leverage the 3927 N push force for robust clamping and pressing operations where exact stroke length must be adjusted on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-20 the Right Cylinder?
Choose this 100 mm bore when you need 3927 N push force at 0.5 MPa, stepping up from a 63 mm bore that provides 1559 N. The adjustable stroke is ideal for product changeovers, allowing you to fine-tune the retract end position without adding external stops. For fixed travel, a standard SAI cylinder is sufficient.
Because the nominal stroke is 160 mm, an external guide is recommended to manage side loads. The rear adjuster acts as a travel stop for end-position tuning, not a lock; it will not hold the load without live air. For true load-holding without pressure, consider 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.
Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-20 FAQ
The rear adjuster screw lets you trim the effective travel by up to 20 mm, creating a 140-160 mm usable window. It acts as a mechanical stop to fine-tune the retract position without changing the cylinder itself.
At 0.5 MPa operating pressure, it provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
