About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X280-100S
The AirTAC SAIJ160X280-100-S is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated rear stroke adjuster. It provides a nominal 280 mm stroke that can be fine-tuned backward by up to 100 mm, creating a usable travel window of 180 to 280 mm. Delivering 10053 N of push force at 0.5 MPa, it handles heavy-duty positioning with precision.
This SKU includes a carbon steel piston rod and PT tapered port threads. The extruded aluminum barrel incorporates sensor grooves on both sides for direct mounting of CMSE reed and DMSE electronic switches. The rear adjuster functions strictly as a travel stop for commissioning end-position tuning and does not lock the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X280-100S Is Used
Heavy Press Tuning
Dial in the exact 180 to 280 mm retract position during heavy press commissioning to accommodate varying material thicknesses without swapping cylinders.
Product Changeover
Adjust the rear stopper up to 100 mm on packaging lines to quickly shift end positions when running different product sizes.
Automated Assembly
Leverage 10053 N of thrust at 0.5 MPa for robust assembly operations while fine-tuning the stroke end-point to match fixture tolerances.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X280-100S the Right Cylinder?
Select this 160 mm bore cylinder when an application requires substantial thrust—10053 N push and 9425 N pull at 0.5 MPa—along with variable end-stop positioning. If your process requires less force, stepping down to the 125 mm bore yields 6136 N push, while moving up to the 200 mm bore provides 15708 N. Choose the adjustable SAIJ format over a fixed-stroke SAI when you need to dial in the exact retract position during machine setup or product changeover without adding external stops.
For an exact ISO 15552 replacement match, verify the 160 mm bore, 280 mm stroke, 100 mm adjustment range, PT port thread, and the -S magnet option. Note that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the stroke exceeds 300 mm thresholds in some setups, ensure you use an external guide to manage side loads on the 40 mm rod. For load-holding without live air, use a SAIL or BSAI cylinder instead of relying on the adjuster.
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 SAIJ160X280-100S FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 2050 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke from 280 mm down to 180 mm. It is used for fine-tuning end positions at commissioning and is not a lock; the cylinder requires live air to hold its position.
