About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX600-30
The AirTAC SAIJ200X600-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits a usable travel window of 570 to 600 mm. Built with a robust 40 mm SUS420J2 stainless steel rod and a heavy-duty M36x2 thread, it handles massive loads up to 28274N at 0.9 MPa. This profile barrel design integrates sensor grooves on three sides for flexible switch placement.
A PT tapered port ensures a tight pneumatic seal, while the rear adjuster allows precise end-position tuning at commissioning without adding external stops. The adjuster acts solely as a travel stop and does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX600-30 Is Used
Heavy Press Tuning
Dial in the exact 570-600 mm end position for large metal forming or pressing tasks without installing bulky external mechanical stops.
Product Changeover
Quickly adapt a long-stroke automated line to accommodate different large-scale product dimensions by adjusting the rear stopper.
Automated Assembly
Execute heavy-duty component placement and seating operations that require both high force and precise end-position calibration.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX600-30 the Right Cylinder?
Select this 200 mm bore when 0.9 MPa thrust requirements exceed the 18095N limit of the 160 mm bore, provided your layout can accommodate the larger ISO 15552 footprint and heavier G3/4 porting. The 30 mm adjustment range is ideal for fine-tuning the retract end during machine setup or product changeover, avoiding the need to physically swap a fixed-stroke SAI cylinder.
Because the 600 mm stroke is substantial, the large 40 mm rod provides excellent resistance to side loads, yet an external guide rail is still strongly recommended to prevent premature wear. Mounting options are restricted to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that this SKU omits the -S magnet; adding one enables AirTAC CMSE reed and DMSE solid-state sensors.
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 SAIJ200AX600-30 FAQ
At an operating pressure of 0.9 MPa, this 200 mm bore cylinder generates a push force of 28274N and a pull force of 15080N.
The rear adjuster acts as an external stopper that lets you shorten the effective travel from 600 mm down to 570 mm. It is a travel stop, not a lock, so live air pressure is still required to hold the load.
