About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-20
The AirTAC SAIJ200X170-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. By turning the external stopper screw, you can fine-tune the effective travel down by 20 mm, creating a precise 150-170 mm usable stroke window. This allows exact end-position calibration during commissioning or product changeover without swapping the barrel or adding external stops. It delivers a substantial 15708 N push force at 0.5 MPa and reaches 28274 N at 0.9 MPa.
This heavy-duty unit features a 40 mm diameter piston rod with an M36x2 thread, paired with 50 mm of adjustable pneumatic cushioning at both ends to absorb high kinetic energy. The rod is constructed from SUS420J2 stainless steel (material code A) for enhanced durability against lateral stress, and the barrel is an extruded aluminum profile with sensor grooves on both sides. It operates at speeds of 30-500 mm/s and uses PT tapered port threads.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-20 Is Used
Heavy Press Calibration
Dial in the exact 150-170 mm end-stop during press setup to accommodate different material thicknesses without changing the cylinder.
Product Changeover
Quickly adjust the retract position on automated lines when switching to a new product size, saving hours of mechanical reconfiguration.
Large Assembly Alignment
Fine-tune the end of stroke for heavy-duty alignment tasks, ensuring components seat perfectly without over-traveling.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-20 the Right Cylinder?
Choose this 200 mm bore when your application requires maximum thrust—stepping down to a 160 mm bore yields 10053 N at 0.5 MPa, which may be insufficient for heavy moving masses. The adjustable stroke is ideal when a fixed SAI cylinder cannot accommodate minor variations in end-stop positioning. Because the stroke is 170 mm, external guides are recommended to manage side loads, as even the 40 mm rod and M36x2 thread have limits under high inertia.
When specifying a replacement, match the 200 mm bore, 170 mm stroke, 20 mm adjustment range, PT G3/4 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2—omitting FB, CA, CB, CR). This model has no -S magnet, so it will not work with CMSE or DMSE sensors. Note that the rear adjuster and air cushions act only as travel stops and deceleration; they do not hold the load without live air. For true pneumatic locking, consider the SAIL or BSAI series.
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 SAIJ200AX170-20 FAQ
At 0.5 MPa it provides 15708 N of push force and 15080 N of pull force. At 0.9 MPa, the push force increases to 28274 N.
The rear adjuster screw lets you shorten the 170 mm nominal stroke by up to 20 mm, giving an adjustable travel window of 150-170 mm. This stopper only sets the travel end and does not lock the load without continuous air pressure.
