About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX110-50S
The AirTAC SAIJ160X110-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust performance for heavy-duty applications. The -50 adjustment code creates a usable travel window between 60 and 110mm, allowing precise end-position tuning without swapping out the entire cylinder. This unit includes a SUS304 stainless steel rod (option B) for superior corrosion resistance and carries the -S magnet option for seamless integration with AirTAC CMSE reed and DMSE electronic sensors.
Unlike a fixed-stroke SAI cylinder, this model uses an external rear stopper screw to trim the effective stroke by up to 50mm during commissioning. The adjuster functions strictly as a travel stop to set the end position, not as a lock, meaning it cannot hold a load without live air pressure. For true load-holding requirements, an external pilot-operated check valve or an AirTAC SAIL cylinder should be specified instead. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ160BX110-50S Is Used
Variable End-Stop Machining
Dial in the exact 60-110mm travel window during machine changeovers to accommodate different part lengths without physically replacing the actuator.
Product Size Changeovers
Quickly adjust the retract position on packaging lines to handle varying box sizes, using the 50mm rear stopper screw to fine-tune the end point.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX110-50S the Right Cylinder?
The adjustable stroke is chosen over a fixed SAI when machine setup requires fine-tuning the retract position without adding external stops.
Because this is a large-bore cylinder with a 110mm nominal stroke, the 40mm rod diameter and M36x2 rod thread provide substantial rigidity, though long unsupported strokes still require an external guide. This SAIJ160X110-50-S is dimensionally interchangeable per ISO 15552. When replacing a cylinder, match the 160mm bore, 110mm stroke, 50mm adjustment, PT tapered port thread, SUS304 rod material, and the -S magnet option. Operating speed ranges from 30-500 mm/s.

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 SAIJ160BX110-50S FAQ
The rear adjuster screw acts as a mechanical stop that lets you trim the effective stroke by up to 50mm, creating a usable travel window between 60 and 110mm. It sets the end position but does not lock the load without live air pressure.
At the maximum 1.0 MPa pressure, it delivers up to 2050 kgf.
