About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-10S
The AirTAC SAIJ200X175-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 175 mm stroke by up to 10 mm. This creates a precise 165 to 175 mm usable travel window for fine-tuning end positions at commissioning without adding external stops. As the largest bore in the series, it delivers immense thrust, pushing with 15708 N and pulling with 15080 N at a 0.5 MPa operating pressure.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The -S suffix indicates an integrated magnet for position sensing, designed to work seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches mounted into the dual-side sensor grooves on the extruded aluminum barrel. Fluid ports are PT tapered thread type (G3/4), and the cylinder achieves a maximum energy absorption of 50 mm via its adjustable air cushions at both ends.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-10S Is Used
Variable End-Stop Tuning
Dial in the exact 165 to 175 mm travel distance during machine commissioning to accommodate varying product sizes without physically swapping out the cylinder.
Heavy Pressing Operations
Leverage the 15708 N push force at 0.5 MPa for heavy-duty pressing, forming, or clamping tasks where precise contact position is critical.
Product Changeover Setup
Quickly adjust the retract end-position by up to 10 mm during production line changeovers, reducing downtime and eliminating the need for external mechanical stopper blocks.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-10S the Right Cylinder?
Choose this 200 mm bore when your application demands the highest force class in the SAIJ range, delivering 15708 N of push force at 0.5 MPa. If your load requirement drops, stepping down to a 160 mm bore yields 10053 N of push force, while moving up is not possible as this is the maximum size. The adjustable stroke is selected over a fixed SAI cylinder when machine setups require variable end-stops or product-size changeovers demand exact end-position tuning without physically swapping the cylinder.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 175 mm stroke, 10 mm adjustment range, PT G3/4 port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. Because the stroke is 175 mm, side-load risks are moderate, but long unsupported loads should still use an external guide. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For dead-load holding, consider SAIL or BSAI series cylinders.
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 SAIJ200AX175-10S FAQ
At a 0.5 MPa operating pressure, the 200 mm bore provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it achieves a push force of 28274 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 10 mm from the nominal 175 mm, providing a usable travel window of 165 to 175 mm. This stopper only sets the travel end and does not lock or hold the load without continuous air pressure.
