About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX40-10S
The AirTAC SAIJ200X40-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 30 to 40 mm for precise end-position tuning. Built with a robust 200 mm bore, it generates 15708 N of push force and 15080 N of pull force at 0.5 MPa, making it suitable for heavy-duty pressing and clamping. The extruded aluminum barrel features sensor grooves on both sides for flexible switch placement.
This variant includes a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and ships with a -S magnet for use with AirTAC CMSE reed and DMSE electronic sensors. The PT tapered port threads ensure a tight pneumatic seal, while the rear stopper allows up to 10 mm of stroke reduction without adding external stops.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX40-10S Is Used
Heavy-Duty Pressing
Delivers up to 15708 N of thrust at 0.5 MPa for assembling large components, with the 10 mm adjuster allowing precise control over the final 30-40 mm pressing depth.
Machine Setup Tuning
Fine-tune the end-stop position during initial commissioning or product changeover directly via the rear screw, avoiding the need to physically swap cylinders.
Industrial Clamping
Secures oversized workpieces securely using its 200 mm bore power, while the SUS420J2 stainless rod withstands harsh manufacturing environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX40-10S the Right Cylinder?
Choose this 200 mm bore cylinder when an application demands massive thrust, stepping up significantly from the 160 mm bore which provides 10053 N of push force at 0.5 MPa. The adjustable stroke is ideal for short-stroke pressing tasks where you need to dial in the exact 30-40 mm travel window during commissioning without swapping out the cylinder for a fixed-stroke SAI model. For ISO 15552 replacement matching, verify the 40 mm stroke, 10 mm adjustment, PT G3/4 port, and the -S magnet requirement.
Because the 40 mm stroke is well below the 300 mm threshold, side-loading on the 40 mm rod is minimal, though external guides are still recommended for heavy off-center loads. Remember that the rear adjuster functions strictly as a travel stop and does not hold the load without live air; for true load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ200AX40-10S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the 40 mm nominal stroke by up to 10 mm, creating a usable travel window of 30 to 40 mm. It only sets the travel end and does not lock the load without continuous air pressure.
