About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX160-75
The AirTAC SAIJ200X160-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a substantial 15708N push and 15080N pull at 0.5 MPa, utilizing a robust 40mm piston rod. The integrated rear stopper allows you to fine-tune the effective travel down from the 160mm nominal stroke, creating a usable window of 85 to 160mm to perfectly dial in end positions during commissioning.
This heavy-duty actuator features a SUS420J2 stainless steel rod for superior corrosion resistance and uses PT tapered port threads on the G3/8 connections. Unlike fixed-stroke actuators, this adjustable model eliminates the need to swap cylinders when product sizes change. The extruded aluminum barrel includes sensor grooves on both sides, ready for electronic DMSE or reed CMSE switches if a magnet is specified later. The rear adjuster functions strictly as a travel stop and deceleration point, not a lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX160-75 Is Used
Heavy Press Changeover
Dial in the 85 to 160mm travel window during heavy press setups, accommodating different material thicknesses without physically swapping the actuator.
Variable End-Stop Positioning
Use the rear stopper screw to establish precise retraction limits on large assembly lines, tweaking the final end-position at machine commissioning.
Large Format Material Handling
Leverage the 15708N push force at 0.5 MPa to move heavy pallets or large structural components, adjusting the stroke to suit varying product dimensions.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX160-75 the Right Cylinder?
Select this 200mm bore when your application requires extreme thrust that smaller bores cannot provide, such as shifting from a 160mm bore that yields 10053N push at 0.5 MPa to this model's 15708N. The 75mm adjustment range is ideal for machinery requiring frequent product changeovers, allowing operators to set variable end stops without adding external physical stops. Because the stroke is 160mm, which is below the 300mm side-load threshold, you have more flexibility in mounting, though the heavy 40mm rod further resists minor deflection. If your process requires the load to be held mechanically without live air pressure, this cylinder's adjuster will not suffice; you must specify a SAIL pneumatic lock or BSAI clamp-lock cylinder instead.
To replace an ISO 15552 cylinder with this SAIJ model, verify the 200mm bore, 160mm nominal stroke, 75mm adjustment range, PT threaded G3/8 ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this adjustable series.

- ✓ 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 SAIJ200AX160-75 FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder generates a push force of 15708N and a pull force of 15080N. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 160mm nominal stroke by up to 75mm, providing a usable travel window of 85 to 160mm. It only sets the travel end and does not lock or hold the load without continuous air pressure.
