About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX190-75S
The AirTAC SAIJ160X190-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end-position without adding external stops. It provides a usable travel window of 115 to 190 mm, giving you a 75 mm adjustment range to dial in during machine commissioning or product changeovers. It delivers substantial thrust, pushing with 14074 N at 0.7 MPa and pulling with 9425 N at 0.5 MPa.
This unit includes a SUS304 stainless steel rod (option B) for superior corrosion resistance and uses PT tapered port threads with a G3/4 connection. The extruded aluminum barrel includes sensor grooves on both sides, and because this is an -S magnet model, it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise end-of-stroke detection. The rear adjuster acts purely as a travel stop and deceleration point, meaning it does not hold the load without live air pressure.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX190-75S Is Used
Product Changeover
Dial in the 115-190 mm travel window during format changes on packaging lines, using the rear adjuster to set new retract positions without swapping hardware.
Machine Commissioning
Use the 75 mm adjustment range during initial setup to perfectly time the retract stroke with other machine axes, preventing mechanical crashes before final lock-down.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX190-75S the Right Cylinder?
The rear adjustment screw is ideal for setups requiring frequent product-size changeovers, eliminating the need to swap out a fixed-stroke SAI cylinder. For load-holding applications without live air pressure, this cylinder is not a lock; you should instead specify an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 190 mm nominal stroke, 75 mm adjustment range, G3/4 PT ports, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the 190 mm stroke approaches the mid-range of travel, ensure your mounting configuration handles side loads properly, utilizing external guides if the load is unsupported.
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 SAIJ160BX190-75S FAQ
The rear adjuster screw lets you shorten the 190 mm nominal stroke by up to 75 mm, creating a usable travel window of 115 to 190 mm. This allows precise end-position tuning at the retract end without replacing the cylinder.
