About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX190-50S
The AirTAC SAIJ160X190-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 140 to 190 mm for precise end-position tuning. It features a SUS304 stainless steel rod and a magnetic piston for position sensing.
This model includes a -S magnet compatible with AirTAC CMSE reed and DMSE electronic sensors, fitting neatly into the dual sensor grooves on both sides of the profile. The rear stopper acts purely as a travel limit to dial in the 50 mm adjustment range during commissioning; it does not hold the load without live air. For load-holding requirements without pneumatic pressure, consider an external rod lock or the related SAIL lock cylinder.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ160BX190-50S Is Used
Product Changeover
Dial in the 140-190 mm travel window during format size changes on a packaging line without physically swapping the actuator.
Machine Setup
Fine-tune the retract end-position at commissioning to prevent mechanical crashes, relying on the 50 mm adjustment range rather than external hard stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX190-50S the Right Cylinder?
The adjustable 140-190 mm window is ideal for machine setups requiring frequent product changeovers, allowing you to fine-tune the retract position without swapping cylinders or adding external stops. Because the 190 mm stroke exceeds the 300 mm side-load threshold guideline for long strokes, ensure you use an external guide to support the load.
To match this ISO 15552 dimensionally interchangeable cylinder, specify a 160 mm bore, 190 mm nominal stroke, 50 mm adjustment, PT tapered ports, and the -S magnet option. Mounting choices are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Operating speed ranges from 30 to 500 mm/s.
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 SAIJ160BX190-50S FAQ
At 0.7 MPa, the push force increases to 14074 N.
The rear adjuster screw allows you to trim the effective stroke by up to 50 mm, creating a 140 to 190 mm usable travel window. It functions as a mechanical stop for end-position tuning and is not a lock, meaning the cylinder requires live air to hold its load.
