About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-40S
The AirTAC SAIJ200X260-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 28274N at 0.9 MPa. An external adjusting screw lets you shorten the effective travel, providing a usable window of 220-260 mm for this 260 mm nominal stroke. This built-in adjustability allows fine end-position tuning at commissioning without swapping the cylinder or adding external stops.
This large-bore unit features a 40 mm SUS420J2 stainless steel rod and PT tapered port threads. It includes a magnet for position sensing with AirTAC CMSE reed and DMSE electronic switches. The extruded aluminum barrel carries sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-40S Is Used
Heavy Press Tuning
Dial in the exact 220-260 mm travel window for heavy stamping or pressing tasks during machine setup without changing hardware.
Product Changeover
Adjust the retract end-stop rapidly on a production line when switching between product sizes that require massive pushing force.
Large Assembly Positioning
Fine-tune the end position of heavy assemblies during commissioning, relying on the 28274N thrust at 0.9 MPa for secure movement.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-40S the Right Cylinder?
Choose this 200 mm bore when your application requires extreme force, stepping up from a 160 mm bore that yields 18095N push at 0.9 MPa. The adjustable stroke is ideal for product changeovers on a line where the exact end-stop varies, replacing the need for a fixed-stroke SAI cylinder. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For secure load-holding, consider an SAIL air-released lock, a BSAI clamp-lock, or an external rod lock.
For an exact ISO 15552 replacement match, specify a 200 mm bore, 260 mm stroke, 40 mm adjustment, PT port threads, and the -S magnet option. Because the stroke is 260 mm, ensure your setup manages side loads—while the 40 mm rod handles high stress, long unsupported strokes still require an external guide.
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 SAIJ200AX260-40S FAQ
At 0.9 MPa operating pressure, this 200 mm bore cylinder provides a push force of 28274N and a pull force of 15080N. It can deliver a maximum force of 3204 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the 260 mm nominal stroke by up to 40 mm, creating a usable travel window of 220-260 mm. This stopper only sets the travel end and does not lock the load without live air pressure.
