About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX25-10
The AirTAC SAIJ200X25-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa, making it suited for heavy-duty pressing. The integrated adjusting stopper allows you to fine-tune the effective travel within a 15-25 mm window, providing exact end-position control without requiring external stops.
This unit features a robust 40 mm piston rod with an M36x2 thread, engineered to withstand substantial side loads. It incorporates an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, and the pneumatic system operates efficiently at speeds of 30-500 mm/s.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX25-10 Is Used
Heavy-Duty Short-Stroke Pressing
Applies up to 28274 N of push force at 0.9 MPa for high-load stamping or forming tasks, using the 10 mm adjuster to set the exact bottoming depth.
Precision Clamp Positioning
Dials in the 15-25 mm travel window during machine setup to compensate for fixture tolerances, ensuring a workpiece is held securely without over-travel.
Rigid End-Stop Calibration
Replaces external mechanical stops on heavy machinery by utilizing the built-in rear screw, allowing operators to quickly modify the retract end-position during product changeovers.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX25-10 the Right Cylinder?
Select this 200 mm bore cylinder when an application demands extreme force within a very short distance, as stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa. The 10 mm adjustment range is ideal for dialing in precise clamp positions or compensating for mechanical tolerance during machine commissioning, a flexibility a fixed-stroke SAI cannot offer. To match this cylinder for an ISO 15552 replacement, specify the 200 mm bore, 25 mm stroke, PT tapered port threads, and the desired mounting set.
Mounting options for the SAIJ series include Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR configurations. Remember that the rear adjuster functions strictly as a travel stop and does not hold the load without continuous air pressure; for true load-holding, consider an external rod lock or the AirTAC SAIL series.

- ✓ 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 SAIJ200AX25-10 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 its maximum 1.0 MPa pressure, it can deliver up to 3204 kgf of push force.
The rear adjuster acts as a mechanical stop that trims the nominal 25 mm stroke by up to 10 mm, creating a 15-25 mm usable travel window. It only sets the end-position and does not lock the load without live air pressure.
