About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX55-10
The AirTAC SAIJ200X55-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty operations. It yields 15708N of push force and 15080N of pull force at 0.5 MPa. The integrated adjustment screw provides a usable travel window of 45-55mm, allowing you to dial in the exact end position during commissioning without adding external stops.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses PT tapered port threads with a G3/4 connection. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning electronic DMSE or reed CMSE switches cannot be used without modification.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX55-10 Is Used
Heavy Press Tuning
Dial in the exact 45-55mm pressing depth during commissioning to prevent over-travel on high-force stamping tasks.
Product Changeover
Quickly adjust the end-stop by up to 10mm when switching between heavy product variants on the line without swapping cylinders.
Rigid Positioning
Leverage the 40mm SUS420J2 stainless rod and massive 15708N thrust to move and position heavy assemblies accurately.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX55-10 the Right Cylinder?
Selecting this 200mm bore cylinder is appropriate when your application requires extreme force, as stepping down to a 160mm bore reduces the 0.5 MPa push force to 10053N. The 10mm adjustable stroke is ideal for applications needing precise end-position tuning at machine setup, offering flexibility that a fixed-stroke SAI cylinder cannot provide. Because the 55mm stroke is short, side-load concerns are minimal, but the massive 40mm rod and M36x2 thread handle substantial loads.
Remember that the rear adjuster functions strictly as a travel stop, not a lock; the SAIJ200X55-10 cannot hold a load without continuous live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead. This model is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ200AX55-10 FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can achieve a maximum push force of 28274N at 1.0 MPa.
The rear adjuster screw allows you to shorten the 55mm nominal stroke by up to 10mm, providing an effective travel window of 45-55mm. It acts as a mechanical stop for end-position tuning and is not a locking device.
