About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX950-50S
The AirTAC SAIJ160X950-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 900 to 950 mm, letting you dial back the retract position by up to 50 mm during setup. Built with a 40 mm SUS420J2 stainless steel rod and a PT tapered G3/4 port, it generates 18095 N of push force at 0.9 MPa.
This model includes a magnet for CMSE and DMSE sensors, which slot into the extruded aluminum barrel grooves on both sides. The adjustable stopper acts purely as a travel end-limit and works with the variable air cushions to decelerate the load, but it does not lock the piston without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX950-50S Is Used
Heavy Press Tuning
Dial in the exact 900-950 mm end position for large pressing assemblies without machining new hard stops.
Automated Line Changeover
Adjust the retract distance on the fly during product size transitions to accommodate different workpiece lengths.
Large Material Handling
Move heavy loads with up to 18095 N of thrust while using the rear screw to fine-tune the stopping point.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX950-50S the Right Cylinder?
Choose this 160 mm bore when your application requires heavy thrust between 14074 N at 0.7 MPa and 18095 N at 0.9 MPa. If you need less force, stepping down to a 125 mm bore yields 8590 N at 0.7 MPa, while a 200 mm bore offers 21991 N at 0.7 MPa. The 50 mm adjustment range is ideal for fine-tuning the end position on long-stroke machinery without adding external stops or swapping out a fixed-stroke SAI cylinder.
Because the 950 mm stroke is long and unsupported, you must use an external guide to prevent excessive side-loading on the rod. For position holding without continuous air pressure, this cylinder is insufficient; you should select an SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead. It uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
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 SAIJ160AX950-50S FAQ
At 0.9 MPa, this 160 mm bore cylinder generates a push force of 18095 N and a pull force of 9425 N. It can achieve a maximum force of 2050 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the 950 mm nominal stroke by up to 50 mm, providing an effective travel window of 900 to 950 mm. This allows precise end-position tuning at commissioning without replacing the cylinder.
