About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX130-50S
The AirTAC SAIJ200X130-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 21991N at 0.7 MPa. Its defining feature is the external adjusting screw that allows you to shorten the effective stroke by up to 50 mm, creating a precise 80-130 mm usable travel window without changing the cylinder itself. This makes it ideal for high-force applications requiring exact end-position tuning during commissioning.
This model features a SUS420J2 stainless steel rod (code A) for improved corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the G3/4 port ensures adequate airflow for its 30-500 mm/s operating speed range.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX130-50S Is Used
Heavy Press Tuning
Dial in the exact 80-130 mm retract position during heavy press setup, allowing precise end-stop tuning without machining new spacers.
Product Changeover
Adapt to different product sizes on a high-force assembly line by adjusting the rear stopper up to 50 mm during format changeovers.
Sensor Integration
Leverage the built-in magnet with DMSE electronic sensors to confirm the adjusted end-position in automated heavy-duty equipment.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX130-50S the Right Cylinder?
Choose this 200 mm bore cylinder when you need extreme force that smaller bores cannot provide, such as replacing a 160 mm bore that only yields 14074N push at 0.7 MPa. The adjustable 80-130 mm travel window is perfect for product changeovers on heavy machinery, allowing you to fine-tune the retract end-stop on the fly rather than swapping out a fixed-stroke SAI cylinder or adding external stops. For any stroke at or above 300 mm, you would normally need an external guide to prevent side-loading, but this shorter 130 mm stroke is well-supported by the robust 40 mm rod and M36x2 thread.
When specifying a replacement, ensure you match the 200 mm bore, 130 mm nominal stroke, 50 mm adjustment range, PT tapered port threads, and the -S magnet requirement. Remember that the rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ200AX130-50S FAQ
At 0.7 MPa operating pressure, this 200 mm bore cylinder provides 21991N of push force and 21991N of pull force. At 0.5 MPa, it delivers 15708N push and 15080N pull.
The rear adjusting screw acts as a mechanical stop that lets you trim the nominal 130 mm stroke back by up to 50 mm, resulting in a usable travel window of 80-130 mm. It only sets the end position and does not lock the load without live air pressure.
