About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX275-20
The AirTAC SAIJ200X275-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling precise end-position tuning without swapping out the unit. It provides a usable travel window of 255 to 275 mm, letting you dial in the exact retraction point during commissioning or product changeovers. Built to handle heavy loads, it delivers 18095 N of push force at 0.9 MPa.
This heavy-duty actuator features a robust 40 mm SUS420J2 stainless steel rod and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount CMSE reed or DMSE electronic switches directly. The rear adjustment screw acts purely as a travel stop for deceleration and is not a locking mechanism, meaning live air pressure is required to hold the load in place.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX275-20 Is Used
Heavy Press Tuning
Fine-tune the 255-275 mm travel window during setup to apply precise 18095 N clamping force on large metal components without external stops.
Product Size Changeover
Quickly adjust the retraction end-stop on packaging lines to accommodate varying box widths, using the 20 mm trim range to perfect the stroke.
Large Assembly Positioning
Position heavy industrial assemblies accurately by dialing in the rear screw, relying on the 40 mm SUS420J2 rod for robust durability.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX275-20 the Right Cylinder?
Selecting this 200 mm bore actuator is ideal when an application demands up to 18095 N of push force at 0.9 MPa and requires on-the-fly stroke trimming. If you need less force, stepping down to a 160 mm bore yields 14074 N at the same pressure, but the 200 mm profile is necessary for high-thrust operations. Because the 275 mm stroke exceeds the 300 mm threshold, you must use an external guide to support the load and prevent excessive side-loading on the 40 mm rod.
An adjustable stroke is chosen over a fixed SAI cylinder when machinery requires variable end-stops for different product sizes. For an exact ISO 15552 replacement, match the 200 mm bore, 275 mm stroke, 20 mm adjustment, PT ports, and SUS420J2 rod material. Note that if true load-holding without live air is needed, you should pivot to the SAIL or BSAI series, as the SAIJ adjuster cannot secure a load.

- ✓ 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 SAIJ200AX275-20 FAQ
At an operating pressure of 0.9 MPa, this 200 mm bore cylinder provides a push force of 18095 N and a pull force of 15080 N. It can achieve a maximum push force of 15708 N at 0.5 MPa.
The rear adjuster screw allows you to shorten the nominal 275 mm stroke by up to 20 mm, creating a usable travel window of 255 to 275 mm. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
