Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-50
The AirTAC Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 230mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-50
The AirTAC SAIJ200X230-50 is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, engineered to deliver massive thrust in heavy-duty pneumatics. Operating at 0.5 MPa, it provides 15708N push and 15080N pull force, scaling up to a maximum 3204 kgf at 1.0 MPa. The built-in rear adjusting screw allows you to fine-tune the effective stroke, creating a usable travel window between 180 and 230 mm without requiring external stops.
This model features a 40 mm SUS420J2 stainless steel piston rod and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed and DMSE electronic switches. Because the rear adjuster acts purely as a mechanical stop and does not lock the load, you must maintain live air pressure to hold position, or specify a SAIL or BSAI series cylinder for true load-holding capability.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-50 Is Used
Heavy Press Tuning
Dial in the exact 180-230 mm end-stop during machine commissioning to accommodate varying material thicknesses without swapping cylinders.
Automated Assembly Changeover
Quickly adjust the retract end-position on the fly when switching between different product sizes on a high-force assembly line.
Large Fixture Positioning
Set precise travel limits for massive pneumatic clamps and fixtures, relying on the 40 mm rod to handle high side-loading during setup.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-50 the Right Cylinder?
Select this 200 mm bore unit when an application requires extreme force and precise end-position calibration during commissioning or product changeover. If you need less thrust, stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053N, whereas the 200 mm bore provides maximum holding power. The 50 mm adjustment range is ideal for dialing in exact travel on large machinery, avoiding the need to physically swap out a fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 230 mm stroke, 50 mm adjustment range, G3/4 port, and PT thread type. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, explicitly omitting FB, CA, CB, and CR brackets. For any stroke over 300 mm, an external guide is recommended to manage side loads, though this 230 mm travel is well within the 1500 mm standard limit. Operating speed is capped at 30-500 mm/s for this large bore.

- ✓ 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 SAIJ200AX230-50 FAQ
At a standard 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708N of push force and 15080N of pull force. At its maximum rated pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 230 mm stroke by up to 50 mm, providing an effective travel window of 180 to 230 mm. It only sets the travel end and deceleration; it does not lock the load without live air pressure.
