Airtac SAIJ200 Adjustable Cylinder SAIJ200AX40-30S
The AirTAC Airtac SAIJ200 Adjustable Cylinder SAIJ200AX40-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 40mm 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 SAIJ200AX40-30S
The AirTAC SAIJ200X40-30-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty tasks, delivering a substantial 15080 N pull force at 0.5 MPa. It features a rear mechanical stopper that allows you to trim the nominal 40 mm stroke back by up to 30 mm, creating a precise 10 to 40 mm usable travel window for exact product changeovers. This model includes a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and uses PT tapered port threads.
Because the barrel is an extruded aluminum profile rather than a tie-rod design, it carries standard sensor grooves on both sides for direct mounting of CMSE reed and DMSE electronic switches. The rear adjuster acts solely as a travel stop to fine-tune the end position during commissioning; it is not a locking device and will not hold a load without live air pressure. For pneumatic load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX40-30S Is Used
Heavy Press Tuning
Dial in the 10-40 mm travel window during setup to precisely trim the pressing force on massive components without changing the cylinder.
Product Size Changeover
Quickly adjust the retract end-stop on a production line when switching between thick and thin product profiles.
High-Force Positioning
Leverage the 15080 N pull force to shift heavy assemblies into exact final positions using the fine rear stopper adjustment.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX40-30S the Right Cylinder?
Selecting this 200 mm bore model is appropriate when your application demands extreme thrust that exceeds the 9425 N pull force of the neighbouring 160 mm bore at 0.5 MPa. The adjustable stroke is ideal for machinery requiring frequent setup changes, allowing you to dial in the exact end-of-travel position without swapping cylinders or adding external stop blocks. When replacing an ISO 15552 cylinder, match the 200 mm bore, 40 mm stroke, 30 mm adjustment range, PT G3/4 port, and the -S magnet requirement.
Although the 40 mm stroke is short, the massive 40 mm rod diameter and M36x2 thread provide excellent resistance to side loads. For any application scaling up to 300 mm or longer strokes within this bore family, an external guide rail is strongly recommended to prevent rod bending.
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 SAIJ200AX40-30S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can reach a maximum of 3204 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the nominal 40 mm stroke by up to 30 mm, creating a usable travel window of 10 to 40 mm. This stopper only sets the end position; it does not lock the load without live air pressure.
