About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X185-75
The AirTAC SAIJ200X185-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 110-185 mm usable travel window from its 185 mm nominal stroke. Delivering a robust 15708 N push force at 0.5 MPa, it handles heavy-duty positioning with precision. The extruded aluminum barrel includes dual sensor grooves for flexible switch mounting.
This model uses a substantial 40 mm carbon steel rod with an M36x2 thread, paired with a G3/4 PT port to manage high airflow requirements. It supports the standard SAIJ mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2) while omitting FB, CA, CB, and CR brackets. The rear stopper allows exact end-position tuning at commissioning without adding external stops.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X185-75 Is Used
Variable End-Stop Positioning
Set precise 110-185 mm travel endpoints on heavy machinery to accommodate varying material thicknesses without mechanical rebuilds.
Machine Changeover Tuning
Dial in the rear adjuster during product line changeovers to instantly match new stroke requirements and reduce setup time.
Heavy Assembly Pressing
Leverage the 15708 N push force at 0.5 MPa for heavy-duty joining operations, using the adjustable stop to control the final press depth.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X185-75 the Right Cylinder?
Choose this 200 mm bore when the 160 mm bore (10053 N push at 0.5 MPa) is insufficient for your load. The 75 mm adjustment range is ideal for product-size changeovers, letting you dial in the exact 110-185 mm travel without swapping the cylinder. Because the rear adjuster acts only as a travel stop and the air cushions manage deceleration, neither will hold a load without live air pressure. For fail-safe load holding, consider an external pilot-operated check valve, or use AirTAC SAIL or BSAI cylinders. To match an ISO 15552 replacement, verify the 200 mm bore, 185 mm stroke, 75 mm adjustment, G3/4 PT port, and required mounting bracket.
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 SAIJ200X185-75 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. It can deliver up to 318 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that trims the 185 mm nominal stroke, providing an adjustable usable travel window of 110-185 mm. It sets the end position but does not lock the load without live air pressure.
