About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-100S
The AirTAC SAIJ160X140-100-S is a double-acting ISO 15552 profile cylinder featuring a substantial 160 mm bore and a 140 mm nominal stroke. Equipped with a rear mechanical adjuster, it provides a massive 100 mm tuning range, allowing the effective travel to be dialed back to a minimum of 40 mm. This creates a highly versatile 40-140 mm usable window for fine-tuning end positions during machine commissioning. In this -S configuration, the extruded aluminum barrel integrates a magnet for position sensing, operating seamlessly with AirTAC CMSE reed and DMSE solid-state switches.
Delivering immense thrust, this bore size pushes 18095 N at 0.9 MPa and pulls 9425 N at 0.5 MPa. The carbon steel piston rod features an M36x2 thread, paired with 50 mm variable air cushions at both ends to manage heavy kinetic energy. Fluid must be filtered air (40 um), operating within a 0.15-1.0 MPa pressure range and a -20 to +70 C temperature band. The PT tapered port threads ensure a robust, leak-resistant connection in high-flow pneumatic circuits.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-100S Is Used
Heavy Press Fit Tuning
Dial in the exact 40-140 mm insertion depth for heavy-duty press fits during machine setup, preventing tooling damage without machining custom spacers.
Variable Product Changeover
Rapidly adapt the retract end-stop on a packaging line handling different large-format product sizes, utilizing the full 100 mm adjustment range.
Prototyping End-Stop Setup
Experiment with different stroke lengths during equipment R&D to find the optimal kinematic motion profile before finalizing a fixed-stroke SAI design.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-100S the Right Cylinder?
Choose this adjustable-stroke model when your application demands precise end-position tuning without the need to physically swap cylinders or add external stopper blocks. The 100 mm adjustment window is ideal for prototyping or production lines running mixed product sizes, where the retract end-stop frequently changes. If your force requirements are lower, stepping down to a 125 mm bore yields 11045 N of push force at 0.9 MPa, whereas moving up to a 200 mm bore provides 28274 N. The integrated magnet (-S) allows for drop-in electronic position feedback via DMSE sensors.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with ISO 15552 cylinders from other manufacturers, utilizing a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). While the 140 mm stroke is relatively short, the heavy 160 mm bore rod handles high side loads well, though any long unsupported tooling should still use an external guide. Remember that the rear adjuster is strictly a travel stop, not a locking device; the SAIJ cannot hold loads without live air pressure. For fail-safe load holding, consider the AirTAC SAIL or BSAI series.
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 SAIJ160X140-100S FAQ
At 0.9 MPa, this 160 mm bore cylinder provides a push force of 18095 N and a pull force of 9425 N. At the maximum operating pressure of 1.0 MPa, it achieves a push force of 2050 kgf.
The rear adjuster acts as a mechanical stop that trims the retract stroke. With a 140 mm nominal stroke and a 100 mm adjustment range, you can fine-tune the effective travel anywhere from 40 mm to 140 mm without altering the cylinder's physical mounting.
