About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX150-50S
The AirTAC SAIJ200X150-50-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty tasks, delivering 15708N of push force at 0.5MPa and 15080N of pull force. It features a robust 40mm piston rod made of SUS420J2 stainless steel, providing excellent resistance to corrosion and side-load wear. PT tapered ports (G3/4) ensure a tight pneumatic seal under high flow demands.
This model provides an adjustable travel window of 100-150mm via its rear stopper screw. You can dial back the nominal 150mm stroke by up to 50mm during commissioning to perfectly tune end positions without swapping out the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX150-50S Is Used
Heavy Press Changeover
Adjust the 100-150mm travel window on the fly to accommodate different material thicknesses during production line changeovers without replacing the actuator.
Heavy-Duty Positioning
Leverage 15708N of push force at 0.5MPa to move large molds or heavy assemblies, using the rear stopper to fine-tune the final resting position accurately.
Automated Clamp Tuning
Set the exact clamping distance during machine setup using the 50mm adjustment range, ensuring optimal pressure on varying workpiece sizes.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX150-50S the Right Cylinder?
Choose this SAIJ200X150-50-S variant when your application requires exact end-position tuning within a 100-150mm travel window and demands high thrust. If you need slightly less force, stepping down to a 160mm bore yields 10053N of push force at 0.5MPa, but the 200mm bore is necessary for heavy actuation up to 15708N. The adjustable stroke is ideal for product changeovers on a line where the exact retract distance varies, saving the cost of a fixed-stroke SAI cylinder.
Because the 150mm stroke is relatively short for this large bore, side-load risks are minimal, but the heavy mass still requires secure mounting from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider the SAIL or BSAI series instead. This cylinder is dimensionally interchangeable per ISO 15552.
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 SAIJ200AX150-50S FAQ
At 0.5MPa operating pressure, this 200mm bore cylinder generates 15708N of push force and 15080N of pull force. It can reach up to 21991N push force at 0.7MPa.
The rear adjuster screw allows you to shorten the nominal 150mm stroke by up to 50mm, providing a usable travel window of 100-150mm. It functions as a mechanical stop for end-position tuning and is not a lock, meaning it will not hold the load without continuous air pressure.
