About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-40
The AirTAC SAIJ160X230-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 190 to 230 mm, allowing you to dial back the nominal stroke by up to 40 mm during commissioning. Delivering 10053 N of push force at 0.5 MPa, this 160 mm bore unit handles heavy loads with precision.
This configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread. The extruded aluminum barrel incorporates sensor grooves on both sides, though this specific SKU lacks a piston magnet and cannot host CMSE or DMSE switches. It uses the standard SAIJ mounting set, omitting FB, CA, CB, and CR brackets.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-40 Is Used
Variable End-Stop Machining
Dial in the exact 190-230 mm clamping depth on machining fixtures without swapping cylinders or reworking the machine bed.
Product Changeover
Quickly adjust the rear stop for different product sizes on a high-force assembly line, cutting changeover time significantly.
Heavy Assembly Press
Leverage the 10053 N push force at 0.5 MPa for heavy pressing operations while fine-tuning the bottoming position.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-40 the Right Cylinder?
Choose this 160 mm bore cylinder when an application requires substantial thrust, such as 10053 N at 0.5 MPa, but demands fine-tuning of the end position without adding external stops. If your process requires less force, stepping down to a 125 mm bore yields 6136 N at 0.5 MPa. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for true position holding, consider the SAIL or BSAI locking cylinders.
This SAIJ160X230-40 is dimensionally interchangeable per ISO 15552, featuring a PT port, SUS304 rod, and a 40 mm adjustment range. With a 230 mm stroke, the 40 mm diameter rod and M36x2 thread provide excellent rigidity, but long unsupported loads still require an external guide to prevent side-load damage.
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 SAIJ160BX230-40 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 40 mm, creating a usable travel window of 190 to 230 mm. It functions as a mechanical stop to fine-tune the end position and does not lock the load.
At 0.5 MPa operating pressure, it provides 10053 N of push force and 9425 N of pull force. At 0.7 MPa, the push force increases to 14074 N.
