About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX155-100S
The AirTAC SAIJ200X155-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 155 mm nominal stroke by up to 100 mm. This yields a highly flexible 55-155 mm usable travel window, perfect for optimizing end-of-stroke positions during machine commissioning or product changeovers without swapping out the physical actuator. It delivers immense thrust, pushing 15708 N at 0.5 MPa and reaching 21991 N at 0.7 MPa.
This specific SKU features a SUS420J2 stainless steel rod for enhanced durability against environmental exposure, paired with PT tapered port threads (G3/4). The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) directly supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise position feedback. It operates at 30-500 mm/s and utilizes 50 mm variable air cushions at both ends to decelerate heavy loads smoothly.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX155-100S Is Used
Heavy Press Tuning
Dial in the exact 55 to 155 mm pressing distance during machine commissioning to accommodate different material thicknesses without replacing the cylinder.
Product Line Changeover
Quickly adjust the end-stop position on a multi-product assembly line by turning the rear screw, saving time during format changeovers.
Variable Positioning Stops
Set custom retract end-positions for heavy-duty sorting or diverting operations where the required stroke length varies between automated processes.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX155-100S the Right Cylinder?
Selecting this 200 mm bore actuator makes sense when your application demands exceptionally high force and adaptable travel. If your setup requires slightly less thrust, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa while maintaining the same ISO 15552 mounting interface. You would choose this adjustable-stroke SAIJ over a fixed-stroke SAI when you need on-the-fly end-position tuning to accommodate varying product sizes without adding external mechanical stops.
When ordering, confirm the 200 mm bore, 155 mm nominal stroke, 100 mm adjustment range, PT G3/4 port, and the -S magnet option. Because the nominal stroke is 155 mm, you do not need external side-load guides, though the robust 40 mm rod and M36x2 thread handle substantial forces. Remember that the rear adjuster and air cushions only set the travel end and decelerate the load; they do not hold the load without live air. For fail-safe load holding without pneumatic pressure, consider the AirTAC SAIL lock or BSAI clamp-lock series instead. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.
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 SAIJ200AX155-100S FAQ
The rear adjuster screw acts as an external stopper that lets you shorten the effective stroke by up to 100 mm. This creates a usable travel window of 55 to 155 mm, allowing you to fine-tune the retract end-position at commissioning without changing the cylinder or adding external stops.
At 0.5 MPa operating pressure, it provides a push force of 15708 N and a pull force of 15080 N. If you increase the pressure to 0.7 MPa, the push force reaches 21991 N.
