About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX850-50S
The AirTAC SAIJ160X850-50-S is a double-acting ISO 15552 profile cylinder featuring a rear mechanical adjuster that creates an 800-850mm usable travel window. Delivering massive thrust, it pushes 14074N at 0.7MPa and pulls 9425N. This bore uses a G3/4 port and a 50mm air cushion to manage heavy kinetic energy.
Equipped with a SUS420J2 stainless steel rod and an integrated magnet, it supports AirTAC CMSE reed and DMSE electronic sensors via dual-side barrel grooves. The rear stopper acts purely as a travel end-positioner, not a load lock, meaning live air pressure is required to hold the payload.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX850-50S Is Used
Heavy Press Tuning
Dial in the exact bottoming position of a large forming press within the 800-850mm window during setup, ensuring precise crimp depths without swapping cylinders.
Product Changeover Stops
Adjust the retract end stop on the fly when switching between large pallet sizes on a heavy-duty conveyor line, using the 50mm trim to accommodate different load lengths.
Long-Stroke Assembly
Drive large components over an 850mm travel path, using the rear screw to gently tune the final seating position and the 50mm cushion to decelerate heavy masses safely.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX850-50S the Right Cylinder?
Choose this 160mm bore when a 125mm cylinder (providing 8590N push at 0.7MPa) lacks the necessary force, but a 200mm bore would be excessive. The 50mm adjustment window is ideal for fine-tuning the end stop during machine commissioning without adding external stops. Because the 850mm stroke is long, an external guide is strongly recommended to prevent excessive side-loading on the 40mm rod.
For a direct ISO 15552 replacement match, ensure the 850mm stroke, 50mm adjuster, PT tapered ports, and -S magnet are specified. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. If true load-holding without live air is required, select the SAIL or BSAI series instead.
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 SAIJ160 Adjustable Cylinder SAIJ160AX850-50S FAQ
At 0.9 MPa operating pressure, this 160mm bore cylinder provides a push force of 18095N and a pull force of 15080N. At 0.5 MPa, the push force is 10053N.
The rear adjuster screw allows you to shorten the effective stroke by up to 50mm, creating an 800-850mm usable travel window. This stopper only sets the end position; it does not lock the load without live air pressure.
