About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-100
The AirTAC SAIJ100X160-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits precise end-position tuning. It provides a usable travel window of 60 to 160 mm, allowing you to dial back the nominal 160 mm stroke by up to 100 mm without adding external stops. In the 100 mm bore class, it delivers a robust 7068 N of push force at 0.9 MPa operating pressure.
This unit is configured with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic solid-state switches. The rear adjustment screw acts purely as a travel stop for deceleration and positioning, meaning it will not hold a load dynamically without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-100 Is Used
Product Changeover
Quickly adapt the retract stroke distance when switching between different sized parts on a single production line without physically swapping cylinders.
End-Position Tuning
Fine-tune the 60 to 160 mm travel window during machine commissioning to achieve exact mechanical stops without adding external spacers.
High-Force Positioning
Leverage the 7068 N push force to move heavy jigs into precise final positions while retaining the ability to back off the stop by up to 100 mm.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-100 the Right Cylinder?
Choose this 100 mm bore cylinder when an application requires high thrust (up to 7068 N at 0.9 MPa) alongside substantial on-machine travel flexibility. If you need less force, stepping down to an 80 mm bore yields 4523 N at 0.9 MPa, whereas moving up to a 125 mm bore provides 11045 N. The SAIJ series is selected over a fixed-stroke SAI cylinder when you need to fine-tune the retract end during commissioning or accommodate frequent product-size changeovers.
For a drop-in ISO 15552 replacement, match the 100 mm bore, 160 mm nominal stroke, 100 mm adjustment range, PT port threads, and SUS304 (B) rod material. Note that SAIJ supports a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the 160 mm stroke is below the 300 mm threshold, side-load concerns are minimal, but the 25 mm rod diameter still handles standard loads effectively. To hold a load without continuous air, use an external rod lock or select the SAIL or BSAI series instead.

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 SAIJ100BX160-100 FAQ
This 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force at 0.5 MPa. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw allows you to shorten the effective travel from the 160 mm nominal stroke down to as little as 60 mm. It functions as a mechanical stop to set the deceleration point and does not lock or hold the load without live air pressure.
