About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX95-40
The AirTAC SAIJ200X95-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 95 mm stroke that can be dialed back by up to 40 mm, yielding a usable travel window of 55 to 95 mm for precise end-position tuning during commissioning. In this configuration, the 200 mm bore generates 15708 N of push force and 15080 N of pull force at 0.5 MPa, making it suited for moving heavy industrial loads.
This unit features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance compared to standard carbon steel. It uses PT tapered port threads and operates without a magnet. The extruded aluminum barrel includes sensor grooves on both sides, allowing for flexible mounting of CMSE reed or DMSE solid-state switches if a magnet is specified later. The rear adjuster acts solely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX95-40 Is Used
Heavy Press Fine-Tuning
Dial in the exact 55 to 95 mm end-of-stroke position during machine setup to accommodate varying material thicknesses without changing the cylinder.
Product Changeover Stops
Adjust the retract stopper on the fly when switching a production line to a different package size, saving downtime on external stop hardware.
High-Force Positioning
Leverage the 15708 N push force at 0.5 MPa to move heavy pallets or industrial fixtures, using the rear screw to set the exact resting position.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX95-40 the Right Cylinder?
Choose this 200 mm bore cylinder when an application demands up to 15708 N of push force at 0.5 MPa combined with on-the-fly stroke trimming. The 40 mm adjustment window is ideal for product changeovers on a line, preventing the need to physically swap cylinders or bolt on external stops. If an application requires less force, stepping down to a 160 mm bore provides 10053 N of push force at 0.5 MPa while maintaining the ISO 15552 mounting footprint.
For load-holding requirements without continuous live air pressure, note that this SAIJ model's rear adjuster functions only as a travel stop, not a lock. A plain SAIJ cylinder will not hold its position unpowered; for true fail-safe load holding, consider the SAIL air-released lock or BSAI clamp-lock cylinder variants. When replacing an ISO 15552 cylinder, verify the 200 mm bore, 95 mm stroke, 40 mm adjustment, PT port thread, and the required mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).

- ✓ 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 SAIJ200AX95-40 FAQ
At a 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the effective travel from its 95 mm nominal stroke down to 55 mm, creating a 55 to 95 mm usable window. The adjuster sets the retract end-position but does not lock or hold the load without live air pressure.
