Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-50S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-50S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 900mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-50S
The AirTAC SAIJ160X900-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 900 mm nominal travel by up to 50 mm for a usable window of 850-900 mm. It delivers robust thrust, pushing 14074 N and pulling 9425 N at 0.7 MPa, making it suitable for moving heavy loads. This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for direct mounting of CMSE reed or DMSE electronic sensors along the dual-side barrel grooves.
Because the 900 mm stroke approaches the maximum standard travel for this bore, the external rear stopper provides critical fine end-position tuning during commissioning without adding external stops. The adjuster acts purely as a travel stop and, alongside the standard air cushions, does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-50S Is Used
Large Assembly Presses
Dial in the 850-900 mm travel during setup to ensure perfect pressing depth on heavy components without physically swapping the cylinder.
Product Size Changeovers
Quickly adjust the retract stop on a packaging line to accommodate varying pallet heights, maintaining precise end-positioning across runs.
Heavy Material Handling
Fine-tune the end-of-stroke position on large automated material transfer lines, leveraging the 14074 N push force to move substantial weights.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-50S the Right Cylinder?
Choose this 160 mm bore when the 100 mm bore (pushing 5497 N at 0.7 MPa) cannot move your payload, or step down if the 80 mm bore (pushing 3518 N at 0.7 MPa) suffices. An adjustable stroke is selected over a fixed SAI cylinder when a machine requires variable end-stops for product changeovers or precise commissioning tuning.
When matching an ISO 15552 replacement, verify the 160 mm bore, 900 mm stroke, 50 mm adjustment range, PT tapered port thread, and the -S magnet option. Given the 900 mm stroke, the 40 mm rod diameter and M36x2 thread handle substantial loads, but an external guide is strongly recommended to prevent side-loading damage on long unsupported travels.
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 SAIJ160AX900-50S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N. It can deliver a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the 900 mm nominal stroke by up to 50 mm, creating a usable travel window of 850-900 mm. It functions as a travel stop for end-position tuning, not a lock, and does not hold the load without live air pressure.
