About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-50
The AirTAC SAIJ100X110-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 3927N of push force at 0.5 MPa. It features a 25mm SUS420J2 stainless steel rod (material option A) and a PT tapered port thread. The -50 adjustment code allows you to dial back the 110mm nominal stroke by up to 50mm, creating a precise 60-110mm usable travel window for exact end-position tuning.
Because the rear adjuster acts purely as a mechanical stop, it will not hold a load without live air pressure; for true position holding, a SAIL or BSAI series cylinder is required. This model uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-50 Is Used
Machine Changeover
Dial in the 60-110mm travel window during product size transitions without swapping the cylinder or adding external stops.
Variable End-Stop Positioning
Fine-tune the retract position on a conveyor sorting line to accommodate different package dimensions on the fly.
Commissioning Stroke Tuning
Use the 50mm rear adjustment screw to precisely set the end-of-stroke position during initial machine setup and calibration.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-50 the Right Cylinder?
Choose this 100mm bore when the 80mm bore (providing 2513N push at 0.5 MPa) is insufficient for your load, or step down if the 80mm offers enough force. The SAIJ100X110-50 is selected over a fixed SAI cylinder when a variable end-stop is needed for product changeovers or commissioning fine-tuning. Ensure your setup matches the PT port thread, 50mm adjustment range, and ISO 15552 mounting interface. Since the nominal stroke is 110mm, a side-load guide is not strictly required, but the robust 25mm rod handles higher off-axis loads better than smaller bores.
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 SAIJ100AX110-50 FAQ
At 0.5 MPa operating pressure, the 100mm bore provides 3927N of push force and 3681N of pull force. At 0.9 MPa, the push force increases to 7068N.
The rear adjuster screw trims the 110mm nominal stroke by up to 50mm, giving an effective adjustable travel range of 60-110mm. The adjuster acts as a travel stop and does not lock the load without continuous air pressure.
