About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-100S
The AirTAC SAIJ200X175-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 15708N at 0.5 MPa. Its defining feature is the 100mm adjustment range, which creates a usable travel window of 75-175mm. This allows operators to dial in the exact retract end-position during commissioning without swapping out the entire actuator.
This unit features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and fluid supply is driven through a PT G3/4 tapered port.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-100S Is Used
Heavy Press Changeover
Use the 75-175mm travel window to quickly reset retract depths when swapping heavy press dies, avoiding the need to physically replace or shim actuators.
Variable End-Stop Tuning
Dial in the exact end-position during machine commissioning using the rear stopper screw, providing precise positioning for high-tonnage operations.
Large Part Forming
Leverage the 15708N push force at 0.5 MPa to form large metal or composite parts, adjusting the stroke window on the fly for different material thicknesses.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-100S the Right Cylinder?
Choose this 200mm bore actuator when an application demands extreme force, offering 15708N push and 15080N pull at 0.5 MPa. If the full 200mm capacity is unnecessary, stepping down to a 160mm bore yields 10053N of push force. The adjustable stroke is ideal for product-size changeovers on a line, acting as a built-in mechanical stop to fine-tune the retract distance. Remember that the rear adjuster only sets the travel end; it does not hold the load without live air. For true load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder.
When replacing an ISO 15552 cylinder, match the 200mm bore, 175mm nominal stroke, 100mm adjustment, PT G3/4 port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Because the stroke exceeds 300mm on larger variants, always support long strokes with an external guide to prevent side-loading, though this 175mm stroke is well within standard limits.
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 SAIJ200AX175-100S FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At 0.7 MPa, the push force increases to 21991N.
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back by up to 100mm. For this 175mm nominal stroke cylinder, it creates a usable travel window of 75-175mm, allowing you to fine-tune the end position without external stops.
