About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX600-20S
The AirTAC SAIJ200X600-20-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, delivering a substantial 15708N of push force at 0.5 MPa. It features a 600mm nominal stroke equipped with a rear adjuster screw, providing a precise 580-600mm usable travel window for fine-tuning the retract end position during commissioning. This eliminates the need to swap cylinders or bolt on external stops when dialing in the final position.
Built for demanding environments, this variant incorporates a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides, and the unit operates at 30-500 mm/s. It utilizes PT tapered G3/4 ports and includes adjustable air cushions at both ends to decelerate the massive 3204 kgf maximum load smoothly.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX600-20S Is Used
Heavy-Press Positioning
Fine-tune the 580-600mm travel window on large metal-forming presses to accommodate varying material thicknesses without mechanical rebuilds.
Pallet Diverting
Adjusts the retract stopper distance on heavy-duty conveyor sorters to handle different pallet sizes during production line changeovers.
Automated Assembly Setup
Dials in the exact end-of-stroke position for large component mating, allowing operators to trim up to 20mm of travel during initial machine commissioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX600-20S the Right Cylinder?
Selecting this 200mm bore model is appropriate when your application requires up to 15708N of thrust at 0.5 MPa (or 21991N at 0.7 MPa). If your force requirements are lower, stepping down to the 160mm bore yields 10053N at 0.5 MPa, whereas moving up is impossible as this is the largest standard SAIJ size. The 20mm rear stroke adjuster is chosen when you need variable end-stop positioning for product changeovers rather than a fixed-stroke SAI cylinder. Remember that the rear adjuster acts only as a travel stop and the air cushions only manage deceleration; neither will hold the load without live air pressure. For fail-safe load holding, consider the SAIL or BSAI series.
When configuring an ISO 15552 replacement, match these exact parameters: 200mm bore, 600mm stroke, 20mm adjustment range, PT G3/4 ports, and a magnet for sensors (-S). Because the stroke is 600mm, the 40mm diameter rod and M36x2 thread will carry significant side loads, but you must still use an external guide rail to prevent binding over this long unsupported travel. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR.
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 SAIJ200AX600-20S FAQ
At an operating pressure of 0.5 MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum pressure of 1.0 MPa, it delivers a maximum push force of 3204 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 20mm, creating a 580-600mm usable travel window. This stopper fine-tunes the end position at commissioning but does not lock or hold the load without continuous air pressure.
