About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-20S
The AirTAC SAIJ160X115-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering substantial thrust for heavy-duty motion tasks. Outfitted with a carbon steel rod and a PT tapered port, it generates 14074N of push force and 9425N of pull force at 0.7 MPa. The integrated -S magnet enables position sensing across the barrel using AirTAC CMSE reed or DMSE solid-state switches.
This specific SKU features a 115 mm nominal stroke paired with a 20 mm adjustment range, creating a usable travel window between 95 and 115 mm. The rear stopper screw allows you to fine-tune the retract end position at commissioning without physically swapping the cylinder or fabricating external stops. The adjuster strictly functions as a travel stop to set deceleration and end limits, meaning it will not hold a load safely without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-20S Is Used
Product Changeover
Dial in the 95-115 mm travel window during packaging line format changes to accommodate varying carton sizes without replacing hardware.
Press End-Tuning
Fine-tune the retract stop position precisely during machine commissioning to perfect heavy-duty pressing operations.
Heavy Material Handling
Leverage the 14074N push force to move substantial pallets or components, using the rear stopper to set exact motion limits.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-20S the Right Cylinder?
Select this 160 mm bore model when an application requires upward of 9425N of pull force at 0.7 MPa, or step down to the 125 mm bore if your load only requires 5734N to optimize air consumption. An adjustable stroke is chosen over a fixed-stroke SAI cylinder when machinery requires variable end-stops for product changeovers or precise end-position tuning during setup. Because the stroke is 115 mm, external guiding is not inherently mandated, but the robust 40 mm rod and M36x2 thread handle high side-load stresses effectively.
For load-holding applications without continuous compressed air, remember that neither the rear adjuster nor the dual-end air cushions act as a lock or brake. You must integrate an external pilot-operated check valve or select a related AirTAC series like SAIL or BSAI for secure clamping. This SAIJ model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ160X115-20S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a push force of 14074N and a pull force of 9425N. At 0.9 MPa, the push force increases to 18095N.
The SAIJ160X115-20-S has a 115 mm nominal stroke with a 20 mm rear adjuster, providing an effective travel window of 95 to 115 mm. You turn the rear screw to shorten the stroke within this range for exact end-position tuning without adding external stops.
