About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-50S
The AirTAC SAIJ160X350-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window between 300 and 350 mm without adding external stops. Built with a robust 160 mm bore, it delivers substantial thrust, pushing 14074 N at 0.7 MPa and pulling 9425 N at the same pressure.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing with CMSE reed or DMSE electronic switches. The extruded aluminum barrel incorporates sensor grooves on both sides, and the PT tapered ports ensure a tight pneumatic connection for high-flow demands.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-50S Is Used
Heavy Press Tuning
Dial in the exact 300-350 mm end-of-stroke position during heavy press commissioning to accommodate varying material thicknesses without swapping cylinders.
Product Changeover Stops
Adjust the retract stopper on the fly to handle different package sizes on a high-thrust conveyor diverting line.
Large Assembly Jigs
Set precise end positions for large-scale assembly jigs where the 18095 N push force at 0.9 MPa is needed to seat heavy components.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-50S the Right Cylinder?
Choose this 160 mm bore when an application requires heavy thrust between the 100 mm bore (5497 N push at 0.7 MPa) and the massive 200 mm bore (21991 N push at 0.7 MPa). An adjustable stroke is selected over a fixed SAI when a machine requires end-position tuning during commissioning or product changeover. Note that the rear adjuster acts purely as a travel stop and does not lock the load; for fail-safe load holding without live air pressure, consider an SAIL or BSAI cylinder.
Because the 350 mm stroke is substantial, an external guide is recommended to prevent excessive side-loading on the SUS304 rod. For a direct ISO 15552 replacement match, verify the 160 mm bore, 350 mm stroke, 50 mm adjustment range, PT port thread, and the -S magnet requirement.
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 SAIJ160BX350-50S FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder generates 18095 N of push force and 16373 N of pull force. It can deliver a maximum push force of 10053 N even at a lower 0.5 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 350 mm stroke by up to 50 mm, creating a usable travel window of 300 to 350 mm. It is a travel stop for fine-tuning, not a lock, and does not hold the load without live air pressure.
