About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX45-40S
The AirTAC SAIJ200X45-40-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring exact end-position tuning. Equipped with a rear adjusting screw, it allows you to trim the nominal 45 mm stroke back by up to 40 mm, creating a highly versatile 5-45 mm usable travel window without swapping hardware. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa.
This specific configuration features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic solid-state sensors. Fluid is filtered air, operating pressure is 0.15-1.0 MPa, and it utilizes a G3/4 port. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX45-40S Is Used
Heavy Press Tuning
Dial in the exact 5-45 mm pressing depth during machine setup for heavy assembly tasks requiring up to 15708 N of force at 0.5 MPa.
Product Changeover
Quickly adjust the rear stopper to accommodate varying part sizes on a production line without physically replacing the cylinder.
Robotic End Effectors
Utilize the SUS420J2 stainless steel rod and integrated -S magnet for reliable position feedback in demanding industrial environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX45-40S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your application demands extreme force—such as the 15708 N push at 0.5 MPa—and requires fine-tuning the end-stop during commissioning or product changeover. If you need slightly less force, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa. The adjustable stroke is ideal for dialing in precise 5-45 mm movements, whereas a fixed SAI cylinder locks you into a single 45 mm dimension.
For an exact ISO 15552 replacement match, ensure your specifications align with a 200 mm bore, 45 mm nominal stroke, 40 mm adjustment range, PT tapered port threads, and the -S magnet option. Because the rear adjuster acts only as a travel stop and the air cushions manage deceleration, neither will hold a load without live air pressure; for positive load-holding, consider an external rod lock or the AirTAC SAIL/BSAI series. The 40 mm cushion stroke and robust 40 mm rod diameter handle significant side loads, though external guiding remains best practice for any off-center 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 SAIJ200 Adjustable Cylinder SAIJ200AX45-40S FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. The maximum thrust is 3204 kgf at 1.0 MPa. The operational speed range is 30-500 mm/s.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 45 mm nominal stroke by up to 40 mm. This creates a usable travel window of 5 to 45 mm. It only sets the end position and does not lock the load without continuous air pressure.
