About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-40S
The AirTAC SAIJ200X90-40-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, delivering 15708N of thrust at 0.5MPa. A rear adjusting screw allows you to shorten the nominal 90mm stroke by up to 40mm, creating a precise 50-90mm usable travel window for on-the-fly positioning. This model features a SUS420J2 stainless steel rod, PT tapered ports, and a built-in magnet for position sensing.
Because the rear adjuster acts strictly as a mechanical stop, it decelerates the travel end alongside the 50mm air cushions but does not hold the load without live air pressure. For true load-holding without continuous air, an external rod lock or the AirTAC SAIL pneumatic lock series is required. The extruded aluminum barrel includes sensor grooves on both sides, compatible with CMSE reed and DMSE electronic switches.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-40S Is Used
Heavy Press Tuning
Dial in the exact 50-90mm end position during heavy press setup without changing cylinders, ensuring perfect contact force for oversized material forming.
Product Changeover
Quickly adjust the stroke window up to 40mm on automated packaging lines when switching to different product sizes, minimizing downtime.
Large Assembly Jigs
Leverage the 15708N thrust and stainless steel rod in harsh automotive jigs, using the rear stopper to set precise retraction limits for multi-stage assembly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-40S the Right Cylinder?
Choose this 200mm bore cylinder when your application requires massive push force up to 15708N at 0.5MPa (or 21991N at 0.7MPa), and stepping down to a 160mm bore would drop your output to 10053N. The 40mm adjustment range is ideal for fine-tuning the end position during machine commissioning or product changeovers, eliminating the need to swap out a fixed-stroke SAI cylinder or bolt on external stops. It shares the exact ISO 15552 mounting interface, accepting Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, but omits FB, CA, CB, and CR options.
When ordering, confirm the 200mm bore, 90mm stroke, 40mm adjustment, PT port thread, and the -S magnet option. Although the 90mm stroke is relatively short, the massive 40mm rod diameter and M36x2 thread handle high side loads well, though any long unsupported travel still necessitates an external guide to prevent binding.
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 SAIJ200AX90-40S FAQ
At 0.5MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At 0.7MPa, the push force increases to 21991N.
The rear adjuster screw allows you to mechanically shorten the 90mm nominal stroke by up to 40mm, creating a usable travel window of 50-90mm. It acts as a travel stop and does not lock the load without live air pressure.
