About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX950-10
The AirTAC SAIJ200X950-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the retract end-position by up to 10 mm. This yields a usable travel window of 940-950 mm, providing exact end-stop calibration during commissioning without adding external stops. It delivers immense thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa, making it suitable for heavy-duty industrial handling.
This SKU features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and utilizes PT tapered G3/4 porting. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic sensors if a magnet is added later. The rear adjuster acts purely as a mechanical stop to set deceleration, not as a load lock, so live air must be maintained to hold position.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX950-10 Is Used
Heavy Press Tuning
Dial in the exact 940-950mm end-stop during heavy press commissioning to ensure precise contact force without swapping cylinders.
Product Line Changeover
Adjust the rear stopper by up to 10mm to accommodate slight length variations when switching product sizes on the line.
Large Assembly End-Stop
Use the adjustable retract position to fine-tune large part seating in automated assembly machinery without external shims.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX950-10 the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires massive force, outputting 15708 N of push force at 0.5 MPa, and you need precise 940-950 mm travel tuning. If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa, saving space and air consumption. An adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder.
Because the 950 mm stroke is exceptionally long, the 40 mm rod diameter requires an external guide to prevent excessive side-loading and rod deflection. The SAIJ mounting set is restricted to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. To replace an ISO 15552 cylinder, match the 200 mm bore, 950 mm stroke, 10 mm adjustment, PT G3/4 port, and desired mounting hardware. Note that this cylinder does not hold loads without live air; for true load-holding, consider the SAIL or BSAI series.

- ✓ 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 SAIJ200AX950-10 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.9 MPa, the push force increases to 28274 N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from 950 mm down to 940 mm. It sets the end position but does not lock the load without live air.
