About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-20S
The AirTAC SAIJ100X110-20-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 90 to 110 mm, allowing you to dial back the nominal 110 mm stroke by up to 20 mm during commissioning. Delivering a robust 7068 N of push force at 0.9 MPa, it is built for demanding positioning tasks.
This specific SKU ships with a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and because this unit includes a magnet (-S), it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches. It uses the standard SAIJ mounting set, omitting FB, CA, CB, and CR brackets.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-20S Is Used
End-Position Tuning
Dial in the exact 90 to 110 mm travel limit during machine setup to perfect product seating without machining new hard stops.
Product Changeover
Quickly adapt the cylinder stroke on packaging lines when switching to different sized cartons, using the 20 mm adjustment to accommodate new formats.
Heavy Assembly Press
Leverage the 7068 N push force at 0.9 MPa to seat heavy components, relying on the rear stopper to prevent over-travel damage.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-20S the Right Cylinder?
Choose this 100 mm bore cylinder when a 63 mm bore (providing 2805 N push at 0.9 MPa) is insufficient for your load, but you want to avoid the larger 160 mm class. The adjustable 90-110 mm travel window is ideal for product changeovers or fine-tuning end positions without adding external stops. The 25 mm rod and M20x1.5 rod thread handle high side loads well, but any stroke over 300 mm would still require an external guide.
For ISO 15552 dimensional interchangeability, match these exact specifications: 100 mm bore, 110 mm nominal stroke, 20 mm adjustment range, PT G1/2 ports, and a magnet for position sensing. Remember that the rear adjuster is a travel stop, not a lock; this plain SAIJ cylinder will not hold a load without live air pressure. For fail-safe load holding, consider the SAIL or BSAI series instead.
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 SAIJ100AX110-20S FAQ
At an operating pressure of 0.9 MPa, this 100 mm bore cylinder provides 7068 N of push force and 5497 N of pull force. It reaches a maximum of 801 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the 110 mm nominal stroke down to 90 mm. This allows fine-tuning of the end position at commissioning without swapping the cylinder, though it does not lock the load without live air.
