About the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX195-100S
The AirTAC SAIJ125X195-100-S is a double-acting ISO 15552 profile cylinder engineered for high-force tasks, delivering 6136 N of push force at 0.5 MPa. It features a rear mechanical adjuster that permits you to trim the effective stroke, creating a 95-195 mm usable travel window for precise end-position tuning without swapping hardware.
This variant incorporates a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a magnet (-S) for direct compatibility with CMSE reed and DMSE electronic sensors. Operating at 30-500 mm/s, it utilizes PT tapered port threads (G1/2) and relies on a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX195-100S Is Used
Product Changeovers
Leverage the 95-195 mm travel window to rapidly reconfigure end-stops for varying package sizes on a production line without changing the cylinder.
High-Force Positioning
Utilize the 6136 N push force at 0.5 MPa to move heavy pallets or workpieces into exact alignment before a machining operation.
Commissioning Calibration
Fine-tune the retracted end-position during machine setup to absorb mechanical tolerances and achieve precise multi-axis coordination.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX195-100S the Right Cylinder?
Select this 125 mm bore when an 80 mm bore (2513 N push at 0.5 MPa) lacks sufficient thrust, but a 160 mm bore (10053 N) would be excessive. The 100 mm adjustment range is ideal for product changeovers on packaging lines, allowing operators to dial in the 95-195 mm travel window during commissioning rather than machining external stops.
For ISO 15552 replacement matching, verify the 125 mm bore, 195 mm stroke, 100 mm adjuster, PT port thread, and -S magnet requirement. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for pilot-operated load holding, consider an external rod lock or the AirTAC SAIL series. Since the stroke is under 300 mm, side-load stress is moderate, but external guides are still recommended for heavy lateral loads.
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 SAIJ125 Adjustable Cylinder SAIJ125AX195-100S FAQ
At 0.5 MPa operating pressure, this 125 mm bore cylinder provides 6136 N of push force and 5734 N of pull force. At 0.7 MPa, the push force increases to 8590 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the nominal 195 mm stroke by up to 100 mm. This creates a usable travel window of 95-195 mm, but it does not lock the load without continuous air pressure.
