About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-100S
The AirTAC SAIJ200X230-100-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, featuring a robust 200 mm bore and a PT tapered port. Equipped with a rear mechanical adjuster, it provides a usable travel window of 130 to 230 mm, allowing precise end-position tuning without swapping hardware. As a single-rod actuator, it delivers 15708 N of push force and 15080 N of pull force at 0.5 MPa, scaling up to a maximum of 3204 kgf at 1.0 MPa.
This variant includes an integrated magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors, which seat cleanly into the dual-side sensor grooves on the extruded aluminum barrel. The piston rod is constructed from SUS420J2 stainless steel (code A), offering elevated corrosion resistance compared to standard carbon steel. It supports a controlled operating speed of 30-500 mm/s and relies on 50 mm variable air cushions at both ends to decelerate massive loads smoothly.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-100S Is Used
Heavy Machinery Changeover
Adjust the 130-230 mm travel window on the fly to accommodate different large-scale press dies or workpiece lengths without replacing the actuator.
Variable End-Stop Positioning
Dial in the exact retraction point during machine commissioning using the rear screw, preventing the need to machine custom external spacers for heavy jigs.
High-Force Assembly Stations
Leverage the 3204 kgf maximum thrust to seat large bearings or heavy components, tuning the stroke end-point to prevent over-travel and part damage.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-100S the Right Cylinder?
Selecting this 200 mm bore actuator makes sense when your application demands extreme thrust that smaller bores cannot provide, such as replacing a 160 mm cylinder that only yields 10053 N push force at 0.5 MPa. The 100 mm adjustment range is ideal for production lines running mixed product sizes, as operators can dial in the exact stroke end-point during changeovers rather than installing fixed stops or entirely new cylinders. For any stroke at or above 300 mm, an external guide is mandatory to prevent excessive side-loading, but even at this 230 mm travel, ensuring proper load alignment protects the M36x2 rod thread.
When specifying a replacement, verify the 200 mm bore, 230 mm nominal stroke, PT port thread, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, explicitly omitting FB, CA, CB, and CR brackets. Remember that the rear adjuster and air cushions act only as travel stops and deceleration devices; they do not hold the load without live air. For true pneumatic locking without pressure, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ200AX230-100S FAQ
At a 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 rated pressure of 1.0 MPa, it delivers a peak push force equivalent to 3204 kgf.
The rear adjuster acts as an external stopper that allows you to shorten the effective stroke by up to 100 mm, creating a usable travel window of 130 to 230 mm from the factory 230 mm nominal stroke. It is a travel stop only and does not lock the load without continuous air pressure.
