About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-50S
The AirTAC SAIJ160X800-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 10053N of push force at 0.5 MPa. Its 800mm nominal stroke can be dialed back by up to 50mm, creating a precise 750-800mm usable travel window for fine-tuning end positions during machine commissioning. This model features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and PT tapered ports.
Because the adjuster acts purely as a mechanical stop and does not lock the load, live air is required to maintain position; for true load-holding without air pressure, consider the SAIL or BSAI series. An integrated magnet (-S) enables position sensing with CMSE reed or DMSE electronic switches mounted in the dual-side sensor grooves.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-50S Is Used
Variable End-Stop Tuning
Dial in the exact 750-800mm end position during machine setup without swapping cylinders or adding external mechanical stops.
Product Size Changeover
Quickly adjust the rear stopper by up to 50mm to accommodate different product lengths on the same production line.
Long-Stroke Material Handling
Move heavy loads along an 800mm path using 10053N of thrust, relying on the adjuster to fine-tune the transfer endpoint.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-50S the Right Cylinder?
Choose this 160mm bore when an 80mm bore provides insufficient thrust (80mm yields 2513N push at 0.5 MPa) or when stepping down from a 200mm bore (15708N) to optimize air consumption. The adjustable 750-800mm travel window is ideal for product changeovers, whereas a fixed-stroke SAI cylinder is better suited for static, repetitive motions. When replacing an ISO 15552 cylinder, match the 160mm bore, 800mm stroke, 50mm adjustment, PT ports, and -S magnet.
With an 800mm stroke, the 40mm rod diameter and M36x2 thread provide robust support, but the extended length means an external guide is strongly recommended to prevent excessive side-loading on the rod seals.
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 SAIJ160AX800-50S FAQ
At 0.5 MPa operating pressure, this 160mm bore cylinder provides 10053N of push force and 9425N of pull force. It can reach a maximum push force of 18095N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that shortens the effective travel. For this 800mm stroke model, you can trim the stroke back by up to 50mm, creating a usable travel window of 750-800mm to fine-tune the end position without replacing the cylinder.
