About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-75
The AirTAC SAIJ100X160-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 160 mm stroke that can be dialed back by up to 75 mm, creating an 85-160 mm usable travel window for precise end-position tuning at commissioning. It delivers a robust 3927 N push force at 0.5 MPa, making it well-suited for heavy-duty handling.
This variant features an SUS420J2 stainless steel rod (code A) for enhanced 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 sensors. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-75 Is Used
Machine Setup & Changeover
Dial in the 85-160 mm travel window during product line changeovers to set new retract positions without swapping cylinders or bolting on external stops.
Variable End-Stop Positioning
Ideal for assembly stations requiring precise end-position tuning at commissioning, using the 75 mm rear adjustment screw to fine-tune the stroke.
Heavy-Duty Handling
Leverages the 100 mm bore's 3927 N push force at 0.5 MPa to move substantial loads while allowing on-the-fly stroke adjustments for varying product sizes.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-75 the Right Cylinder?
Select this 100 mm bore cylinder when an application demands high thrust—up to 3927 N at 0.5 MPa or 7068 N at 0.9 MPa—along with variable end-stops. If you need less force, a 80 mm bore provides 2513 N at 0.5 MPa; for heavier loads, a 125 mm bore offers 6133 N. Choose this adjustable-stroke SAIJ over a fixed SAI when you need to fine-tune the retract position during machine setup or product changeover without adding external stops. Because the 160 mm stroke is under 300 mm, side-load risks are moderate, but the 25 mm rod and M20x1.5 thread still handle lateral stress well.
Remember that the rear adjuster acts only as a travel stop and the air cushions only manage deceleration; neither holds the load without live air pressure. For position holding without continuous air, consider an AirTAC SAIL pneumatic lock, BSAI clamp-lock, or an external pilot-operated check valve. This cylinder is dimensionally interchangeable per ISO 15552.

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 SAIJ100AX160-75 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster acts as a mechanical stop that lets you shorten the 160 mm nominal stroke by up to 75 mm, providing an 85-160 mm usable travel window. It is a travel stop, not a lock, and does not hold the load without live air pressure.
