About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-40
The AirTAC SAIJ100X150-40 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a substantial 7068N thrust at 0.9 MPa while allowing you to dial back the effective travel within a 110-150 mm usable window. This built-in adjustability lets you fine-tune the retract end position at commissioning without adding bulky external stops.
Built with a SUS420J2 stainless steel rod, it handles lateral stresses better than standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Mounting options span Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR variants found on some standard lines.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-40 Is Used
Machine Setup & Changeover
Fine-tune the 110-150 mm travel window during product changeovers to accommodate different part sizes without physically replacing the actuator.
Variable End-Stop Positioning
Dial in the exact retract end-position at machine commissioning, using the rear screw to trim up to 40 mm off the nominal stroke for precise alignment.
Heavy-Duty Clamping
Leverage the 7068N push force at 0.9 MPa to secure heavy workpieces, using the adjustable stop to set the exact clamping depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-40 the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (delivering 4523N push at 0.9 MPa) cannot provide enough force for your load. The 40 mm adjustment range is ideal for production lines running mixed product sizes, allowing rapid end-stop changes without swapping the cylinder. Since the stroke is 150 mm, side-load risks are minimal, but an external guide is still recommended for heavy off-center loads.
The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure. For load-holding during air loss, select the SAIL (air-released lock) or BSAI (clamp-lock) series instead. To match this ISO 15552 interchangeable cylinder, specify the 100 mm bore, 150 mm stroke, 40 mm adjustment, PT tapered ports, and your required mounting style.
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 SAIJ100AX150-40 FAQ
A rear external stopper screw lets you mechanically shorten the effective stroke by up to 40 mm. This creates a 110-150 mm usable travel window, allowing you to set the exact retract end-position at commissioning without altering the cylinder's fixed mounting.
At 0.9 MPa operating pressure, the 100 mm bore provides 7068N of push force and 5497N of pull force. It can deliver a maximum of 801 kgf at 1.0 MPa.
