About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX950-40S
The AirTAC SAIJ160X950-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 18095 N at 0.9 MPa. Its 950 mm nominal stroke incorporates a 40 mm adjustment range, yielding a precise 910-950 mm usable travel window for exact end-position tuning. This made-to-order configuration features a SUS420J2 stainless steel rod and a PT tapered port thread.
Because the rear screw acts purely as a mechanical stop to trim the retract distance, it does not lock the load without live air. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet pairs directly with AirTAC CMSE reed and DMSE electronic solid-state switches for immediate position feedback.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX950-40S Is Used
Heavy Press Tuning
Dial in the exact 910-950 mm end-stop during press setup to accommodate material thickness variations without changing the cylinder.
Large Product Changeover
Adjust the retract distance on the fly for different pallet sizes on a heavy-duty conveyor line, saving commissioning time.
Automated Assembly Stops
Set precise mechanical end-limits for large assembly jigs, relying on the 18095 N thrust to move substantial loads.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX950-40S the Right Cylinder?
Select this 160 mm bore when an application requires heavy thrust that exceeds the 11045 N pull of a 125 mm cylinder at 0.9 MPa, but does not demand the extreme 28274 N output of a 200 mm unit. The adjustable 910-950 mm window is ideal for product changeovers, letting you fine-tune the retract end-stop at commissioning without swapping hardware. For load-holding without continuous air pressure, this cylinder is insufficient; you must integrate an external pilot-operated check valve or select a SAIL or BSAI series lock cylinder.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 950 mm stroke, 40 mm adjustment, PT G3/4 port, and -S magnet. Mounting choices are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Given the 950 mm stroke, the 40 mm rod and M36x2 thread provide rigidity, but an external guide is mandatory to prevent excessive side-loading on the unsupported rod.
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 SAIJ160AX950-40S FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder provides 18095 N of push force and 14074 N of pull force. It operates efficiently in the 30-500 mm/s speed range.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 950 mm nominal stroke by up to 40 mm, creating a 910-950 mm travel window. It sets the end position but does not hold the load without live air pressure.
