About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX155-30
The AirTAC SAIJ100X155-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 155 mm stroke that can be fine-tuned down by up to 30 mm, yielding a precise 125-155 mm usable travel window. Delivering 5497 N of push force at 0.7 MPa, it is built with a SUS420J2 stainless steel rod for enhanced corrosion resistance.
This model uses PT tapered port threads (G1/2) and operates at speeds of 30-800 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, allowing for direct mounting of CMSE reed or DMSE electronic switches if a magnet is added later. The rear adjuster acts purely as a mechanical stop to set the retraction end position during commissioning, not as a lock to hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX155-30 Is Used
Product Changeovers
Dial in the 125-155 mm travel window during format size changes on a packaging line, avoiding the need to physically swap out the entire actuator.
End-Stop Tuning
Fine-tune the retraction end position at machine commissioning to achieve exact seating of heavy 100 mm bore components without adding external stop blocks.
Assembly Pressing
Leverage the 5497 N push force at 0.7 MPa to seat bearings or parts, using the rear screw to precisely limit the pressing depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX155-30 the Right Cylinder?
Choose this 100 mm bore when an application requires substantial thrust, such as 5497 N push force at 0.7 MPa, but demands on-the-fly end-position tuning without swapping cylinders. If you need less force, stepping down to an 80 mm bore yields 3518 N at 0.7 MPa. The 30 mm adjustment window is ideal for product changeovers on a packaging line, replacing the need to bolt on external stops. For exact ISO 15552 dimensional interchangeability, match the 100 mm bore, 155 mm stroke, PT port thread, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Since the 155 mm stroke is relatively short, side-loading is minimal, but always guide the load externally for rigid stability. Remember that the adjuster only decelerates the travel end; for true load-holding without air pressure, use an external rod lock or a SAIL pneumatic lock cylinder.
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 SAIJ100AX155-30 FAQ
At a standard operating pressure of 0.7 MPa, this 100 mm bore cylinder provides 5497 N of push force and 5158 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm from the nominal 155 mm, creating a 125-155 mm travel window. It acts as a mechanical stop to set the end position and does not lock the load in place without continuous air pressure.
