About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX600-40S
The AirTAC SAIJ160X600-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 10053N push force at 0.5 MPa and features a 600mm nominal stroke that can be fine-tuned down by up to 40mm, yielding a precise 560-600mm usable travel window. This built-in adjustability allows operators to dial in exact end positions during commissioning without adding external stops.
This specific SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the PT tapered port threads match the G3/4 porting standard for this bore size. Air cushions at both ends decelerate the heavy 40mm rod, though the adjuster acts only as a travel stop, not a load lock.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX600-40S Is Used
Large Press Fine-Tuning
Dial in the exact 560-600mm end-of-stroke position during heavy press commissioning without swapping out the entire cylinder or fabricating external shims.
Product Size Changeover
Quickly adjust the retract stop by up to 40mm on a packaging line to accommodate different product lengths, minimizing downtime between production runs.
Heavy Material Handling
Leverage the 10053N push force and SUS304 rod to move heavy assemblies in washdown environments, relying on the rear stop to set precise indexing distances.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX600-40S the Right Cylinder?
Selecting this 160mm bore cylinder makes sense when your application requires the 10053N thrust at 0.5 MPa (or up to 18095N at 0.9 MPa) but demands on-the-fly end-position tuning. If you need less force, stepping down to a 125mm bore yields 6136N; if you need more, a 200mm bore provides 15708N. Because the 600mm stroke is substantial, an external guide is strongly recommended to manage side loading on the extended rod. The SUS304 rod material is specified here for environments where moisture or corrosion is a concern.
Choose the SAIJ adjustable design over a fixed SAI cylinder when machine setups involve product changeovers or variable end-stops. To replace an ISO 15552 cylinder, match the 160mm bore, 600mm stroke, 40mm adjustment, G3/4 PT ports, and the -S magnet. Remember that the rear adjuster only sets the travel limit; for load-holding without live air pressure, you must use an external rod lock, a pilot-operated check valve, or switch to an AirTAC SAIL or BSAI series cylinder.

- ✓ 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 SAIJ160BX600-40S FAQ
At 0.5 MPa operating pressure, this 160mm bore cylinder provides 10053N of push force and 9425N of pull force. At 0.9 MPa, the push force increases to 18095N.
The rear adjuster acts as a mechanical stop that allows you to shorten the 600mm nominal stroke by up to 40mm, providing a usable travel window of 560-600mm. It sets the end position but does not lock the load without live air pressure.
