About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX145-40
The AirTAC SAIJ100X145-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end position. It provides a usable travel window of 105 to 145 mm, enabling precise end-position tuning during commissioning without swapping out the entire unit. Built with a 25 mm piston rod and SUS420J2 stainless steel (code A), it delivers a robust 5497 N push force at 0.7 MPa.
This extruded aluminum barrel cylinder includes variable air cushions at both ends to decelerate the moving load smoothly. The rear adjuster acts strictly as a mechanical stop to set the travel limit and does not hold the load without live air pressure. It features PT tapered ports sized G1/2 and utilizes the standard SAIJ mounting set, including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX145-40 Is Used
Machine Changeover
Dial in the 105-145 mm travel window during product size changes to set new retract positions without physically replacing the cylinder.
End-Position Tuning
Fine-tune the final retract position at machine commissioning using the rear stopper to correct for mechanical tolerances.
High-Force Positioning
Leverage 5497 N of push force at 0.7 MPa to move heavy jigs while retaining the flexibility to trim the stroke by up to 40 mm.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX145-40 the Right Cylinder?
Choose this 100 mm bore adjustable-stroke cylinder when your application requires high thrust (5497 N at 0.7 MPa) alongside variable end-stop positioning. If your force requirements are lower, stepping down to an 80 mm bore yields 3518 N at 0.7 MPa, whereas moving up to a 125 mm bore provides 8590 N. The 40 mm adjustment range is ideal for product-size changeovers on a packaging line, removing the need to bolt on external stops.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 145 mm stroke, G1/2 PT ports, and the required mounting interface. Note that the SAIJ series omits FB, CA, CB, and CR mounts. For load-holding without continuous air pressure, select a SAIL (air-released lock) or BSAI (clamp-lock) cylinder, as this adjuster is not a brake. At 145 mm stroke, side-load is minimal, but always ensure adequate guiding for unsupported 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 SAIJ100AX145-40 FAQ
At an operating pressure of 0.7 MPa, this 100 mm bore cylinder generates 5497 N of push force and 3681 N of pull force. It can deliver up to 7068 N push force at 0.9 MPa.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the 145 mm nominal stroke by up to 40 mm. This creates a usable travel window of 105 to 145 mm, but it does not lock or hold the load without live air pressure.
