About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX125-100S
The AirTAC SAIJ200X125-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering immense thrust up to 15708N at 0.5 MPa and a maximum of 3204 kgf at 1.0 MPa. Featuring a robust 40mm carbon steel rod and M36x2 thread, it handles heavy loads effectively. The built-in -S magnet enables precise position detection using CMSE reed or DMSE electronic solid-state sensors mounted in the dual-side barrel grooves.
This model provides a usable travel window of 25-125mm, allowing you to dial back the nominal 125mm stroke by up to 100mm during commissioning. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position without adding external stops. Remember it is not a lock; for load-holding without live air pressure, consider SAIL or BSAI variants.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX125-100S Is Used
Heavy Press Tuning
Dial in the exact 25-125mm end-stop on heavy stamping presses during setup, avoiding costly mechanical shims.
Product Changeover
Quickly adapt the retract distance for varying large product sizes on an assembly line without swapping cylinders.
Large Fixture Clamping
Secure massive components by fine-tuning the clamping travel window to compensate for material thickness variations.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX125-100S the Right Cylinder?
Choose this 200mm bore when 160mm (9425N pull at 0.5MPa) is insufficient for your heaviest pushing tasks. The adjustable 25-125mm window is ideal for product changeovers on large presses, preventing cylinder swaps. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB/CA/CB/CR. The PT tapered port and SUS420J2 rod are standard here. Because the stroke is 125mm, external side-load guides are recommended.
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 SAIJ200AX125-100S FAQ
At 0.5 MPa it provides 15708N push and 15080N pull force. At the maximum 1.0 MPa operating pressure, it delivers up to 3204 kgf.
The rear adjuster lets you mechanically shorten the 125mm stroke down to 25mm, creating a 25-125mm travel window. It functions as a stop, not a lock.
