Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-50S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-50S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 110mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-50S
The AirTAC SAIJ100X110-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 7068N of push force at 0.9 MPa and features a 60-110mm usable travel window, allowing you to dial back the 110mm nominal stroke by up to 50mm during machine commissioning. The SUS420J2 stainless steel rod provides excellent corrosion resistance, while the integrated -S magnet enables position feedback via CMSE reed and DMSE electronic sensors.
This adjustable-stroke model uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. The rear adjuster acts purely as a travel stop to fine-tune end positions without requiring external stops or cylinder swaps, but it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI cylinder series.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-50S Is Used
Machine Setup Changeover
Fine-tune the 60-110mm travel window during product changeovers to adapt end positions without physically swapping the cylinder or adding external mechanical stops.
Variable End-Stop Positioning
Adjust the retraction end-point on the fly for conveyor diverters or sorting gates that must handle varying package sizes on the same line.
Heavy-Duty Clamping
Leverage the 7068N push force at 0.9 MPa to secure heavy workpieces, using the 50mm adjustment to dial in the exact clamping depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-50S the Right Cylinder?
Choose this 100mm bore cylinder when your application requires substantial thrust, such as the 7068N push force at 0.9 MPa, combined with precise end-position tuning. If you need less force, stepping down to a 63mm bore yields 2805N push force at 0.9 MPa, whereas moving up to a 125mm bore provides 11045N. The PT tapered port threads ensure a tight, reliable pneumatic seal. Because the nominal stroke is 110mm, an external guide is recommended to manage side loads and prevent premature wear on the M20x1.5 rod thread.
When replacing an ISO 15552 cylinder, match the 100mm bore, 110mm nominal stroke, 50mm adjustment range, PT port threads, and the -S magnet requirement. The SAIJ is preferred over a fixed-stroke SAI when you need variable end stops to accommodate product-size changes on a line. Remember that the rear screw stopper and air cushion only decelerate the travel end; they do not function as a mechanical brake or lock.
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 SAIJ100AX110-50S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 50mm, creating a usable travel window of 60-110mm from the 110mm nominal stroke. This allows fine end-position tuning at commissioning without swapping the cylinder.
At 0.9 MPa, it provides 7068N of push force and 6631N of pull force. At 0.5 MPa, the push force is 3927N. The cylinder operates at speeds between 30 and 800 mm/s.
