About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-30S
The AirTAC SAIJ200X170-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 21991 N at 0.7 MPa, making it suitable for heavy-duty operations. The integrated -S magnet enables position detection using AirTAC CMSE reed or DMSE electronic solid-state sensors housed within the dual-side extruded aluminum barrel grooves.
By turning the rear adjusting screw, you can shorten the effective travel by up to 30 mm, creating a precise 140-170 mm usable stroke window. This allows you to fine-tune the retract end position during commissioning without adding external stops. The rod is constructed from SUS420J2 stainless steel (code A) for enhanced durability, and fluid supply is routed through PT tapered ports.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-30S Is Used
Heavy Press Tuning
Dial in the exact 140-170 mm retract position on heavy stamping or press machinery during setup, ensuring perfect contact without mechanical spacer changes.
Product Size Changeover
Quickly adapt large-scale automated production lines to different product dimensions by adjusting the stroke end-point on the fly rather than replacing cylinders.
Variable End-Stop Positioning
Achieve precise lower-end positioning for heavy material handling, using the 30 mm adjustment window to compensate for mechanical tolerance stack-up.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-30S the Right Cylinder?
Choose this 200 mm bore cylinder when an 80 mm bore (delivering 3518 N push force at 0.7 MPa) is insufficient for your heavy load requirements. The adjustable stroke is ideal for applications requiring variable end-stops or frequent product changeovers, saving the effort of swapping out a fixed-stroke SAI cylinder. At a 170 mm stroke, the 40 mm rod and M36x2 thread provide robust support, though any application approaching or exceeding 300 mm of travel should incorporate an external guide to manage side loading.
Remember that the rear adjuster functions strictly as a travel stop and the air cushion only manages deceleration; neither will hold a load without continuous live air. For load-holding requirements without pneumatic pressure, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external rod lock. This SAIJ model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ200AX170-30S FAQ
At 0.5 MPa it generates 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N, with a maximum push force of 28274 N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that lets you trim the nominal 170 mm stroke back by up to 30 mm, providing an effective and finely tunable travel window of 140 to 170 mm. It is a stop only, not a lock, and does not hold the load without live air pressure.
