About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-50
The AirTAC SAIJ160X350-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 300-350 mm usable travel window by trimming the 350 mm nominal stroke up to 50 mm, delivering 10053 N of push force at 0.5 MPa. This heavy-duty actuator uses a SUS304 stainless steel rod and a PT tapered G3/4 port to handle demanding industrial environments.
The integrated rear stopper allows precise end-position tuning during commissioning without adding external stops. It supports a narrower mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU lacks the magnet for CMSE or DMSE switches.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-50 Is Used
Heavy Press Tuning
Dial in the exact 300-350 mm end position for heavy pressing or forming operations during initial machine setup without swapping actuators.
Product Changeovers
Adapt a high-thrust conveyor diverter or stopper block on the fly when packaging dimensions change, utilizing the 50 mm adjustment window.
Variable End Stops
Replace rigid hard stops with a controlled pneumatic stopper to fine-tune the retraction point on large material handling equipment.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-50 the Right Cylinder?
Select this 160 mm bore actuator when an application requires substantial force—10053 N push at 0.5 MPa—combined with a variable end-stop. If a project demands less thrust, stepping down to a 125 mm bore yields 6136 N; if more power is needed, a 200 mm bore provides 15708 N. The adjustable stroke is ideal for product-size changeovers on a line, whereas a fixed SAI cylinder suits fixed-pitch machinery. Because the 350 mm stroke is substantial, an external guide is recommended to manage side loads.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 160 mm bore, 350 mm stroke, 50 mm adjustment, PT G3/4 port, and the SUS304 rod material. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for pilot-operated load holding, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ160BX350-50 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that trims the effective travel. For this 350 mm stroke model, you can fine-tune the usable retraction window down to 300 mm without changing the cylinder or adding external stops.
