About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-50S
The AirTAC SAIJ160X140-50-S is a double-acting ISO 15552 profile cylinder featuring a single rod and an integrated rear stroke adjuster. It delivers robust performance with a 10053N push force at 0.5 MPa and a 14063N pull at the same pressure. Equipped with a standard magnet (-S), the extruded aluminum barrel integrates sensor grooves on both sides, ready to accept CMSE reed or DMSE solid-state switches for precise position verification.
This specific SKU provides a 90-140 mm usable travel window, allowing you to dial back the nominal 140 mm stroke by up to 50 mm. The rear adjustment screw acts purely as a mechanical stop to fine-tune the retract end position during commissioning without adding external stops. It is important to note that this adjuster is not a locking device; the cylinder cannot hold a load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-50S Is Used
Product Changeover
Dial in the 90-140 mm retract distance during format changes without physically swapping the cylinder or adding external stopper blocks.
Heavy Press Setup
Leverage the 10053N push force for pressing operations while fine-tuning the end stop to accommodate varying material thicknesses.
Machine Commissioning
Trim the travel by up to 50 mm during initial machine setup to perfectly time the motion sequence and prevent mechanical interference.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-50S the Right Cylinder?
Choose this 160 mm bore variant when your application requires heavy thrust (up to 10053N push at 0.5 MPa) alongside flexible end-position tuning. If your setup needs less force, stepping down to a 125 mm bore yields 6136N push, while moving up to a 200 mm bore provides 15708N. The adjustable 90-140 mm window is ideal for product changeovers on a line, letting you reset the retract distance on the fly instead of swapping out a fixed-stroke SAI cylinder.
For an exact ISO 15552 replacement match, ensure you specify the 160 mm bore, 140 mm stroke, 50 mm adjustment range, PT tapered ports, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. Because the 140 mm stroke is relatively short for this large bore, side-load risks are minimal, but an external guide is still recommended for heavy lateral loads. For true load-holding without live air, consider the SAIL or BSAI series instead.

- ✓ 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 SAIJ160X140-50S FAQ
The rear adjuster screw lets you mechanically shorten the effective travel from 140 mm down to as little as 90 mm. It functions as a physical stop for end-position tuning and does not lock the load in place when air is removed.
At 0.5 MPa, it generates a push force of 10053N and a pull force of 14063N. If operated at 0.7 MPa, the push force increases to 14074N.
