Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-100S
The AirTAC Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 170mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-100S
The AirTAC SAIJ200X170-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 70-170 mm from the 170 mm nominal stroke. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa, making it suited for heavy-duty positioning. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed and DMSE electronic switches.
This variant uses a SUS420J2 stainless steel rod for improved corrosion resistance and pairs with PT tapered port threads. The rear adjustment screw acts purely as a mechanical stop to fine-tune the retract end position during commissioning; it does not lock the load without live air pressure. For load-holding without continuous air, an external rod lock or the SAIL series is required.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-100S Is Used
Heavy Machinery Changeover
Dial in the 70-170 mm travel window during heavy equipment product transitions without replacing the entire cylinder assembly.
Large Press Positioning
Fine-tune the retract end-stop on large metal presses where 15708 N of thrust is required to seat heavy components accurately.
Bulk Material Diversion
Adjust the actuation distance on heavy-duty conveyor diverter arms to handle varying pallet sizes on the fly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-100S the Right Cylinder?
Choose this 200 mm bore cylinder when 160 mm bore output (10053 N push at 0.5 MPa) is insufficient for moving heavy fixtures. The 100 mm adjustment range is ideal for lines requiring frequent product-size changeovers, allowing you to shift the end stop without swapping cylinders or adding external spacers. Unlike a fixed-stroke SAI cylinder, this model dials in the exact end position at commissioning.
When replacing an ISO 15552 cylinder, match the 170 mm stroke, 100 mm adjustment, G3/4 port, and mounting interface. The SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts. Because the stroke is 170 mm, side-load risk is moderate, but for any application approaching 300 mm or more, an external guide is strongly recommended to protect the 40 mm rod. Operating speed is 30-500 mm/s.
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 SAIJ200AX170-100S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. The maximum thrust is 3204 kgf at 1.0 MPa.
The rear adjuster allows you to shorten the effective travel by up to 100 mm, creating a 70-170 mm usable window. It functions as a mechanical stop to set the end position and is not a lock.
