About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX95-50S
The AirTAC SAIJ200X95-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 45-95 mm. Built to deliver immense thrust, it generates 15708 N of push force and 15080 N of pull force at 0.5 MPa. This makes it highly suitable for heavy-duty operations requiring substantial power and precise end-position tuning.
This specific SKU features a SUS420J2 stainless steel rod (option A) and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the G3/4 port ensures high airflow capacity for rapid actuation.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX95-50S Is Used
Heavy Press Tuning
Dial in the exact 45-95 mm pressing distance for heavy assembly operations without needing external mechanical stops.
Machine Changeover
Quickly adjust the retract end-position during product size transitions on large automated production lines.
High-Force Positioning
Leverage the 15708 N push force to shift heavy pallets or molds, fine-tuning the travel limit at commissioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX95-50S the Right Cylinder?
Selecting this 200 mm bore over a smaller neighbor, like the 160 mm bore that yields 10053 N push at 0.5 MPa, is driven by the need for maximum thrust in large-scale machinery. The adjustable 50 mm stroke is ideal for applications requiring variable end stops or fine-tuning during machine commissioning, avoiding the need to physically swap out a fixed-stroke SAI cylinder. To replace this unit, match the 200 mm bore, 95 mm stroke, 50 mm adjustment, PT port thread, and the -S magnet requirement.
Because the nominal stroke is relatively short at 95 mm, external side-load guides are less critical here than with longer strokes. However, remember that the rear adjuster acts solely as a travel stop and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series.
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 SAIJ200 Adjustable Cylinder SAIJ200AX95-50S FAQ
At 0.5 MPa, it provides 15708 N push force and 15080 N pull force. The operating speed range is 30-500 mm/s, and it uses a G3/4 port.
The rear adjuster allows you to shorten the effective travel by up to 50 mm, creating a usable stroke window of 45-95 mm. It functions as a mechanical stop and does not lock the load without air pressure.
