About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-20
The AirTAC SAIJ160X140-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down to a 120-140 mm window. Equipped with a 40 mm carbon steel rod and M36x2 thread, it delivers a robust 14074 N of push force at 0.7 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible positioning of CMSE or DMSE switches.
This model uses PT tapered port threads and provides variable air cushioning at both ends to manage deceleration. The rear stopper mechanism lets you dial in the exact end position during commissioning without adding external stops, though it acts only as a travel stop and will not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-20 Is Used
Heavy Press Tuning
Dial in the exact 120-140 mm end position for heavy pressing tasks during initial machine commissioning without swapping cylinders.
Product Changeover
Quickly adjust the rear stopper to accommodate minor variations in product dimensions on a high-force assembly line.
Variable End Stops
Set precise retract positions for heavy material handling equipment using the integrated 20 mm adjustment range.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-20 the Right Cylinder?
Select this 160 mm bore cylinder when your application requires 14074 N push force at 0.7 MPa and precise end-position tuning within a 120-140 mm travel window. If your force requirements are lower, stepping down to the 125 mm bore yields 8590 N push at 0.7 MPa. Choose this adjustable SAIJ variant over a fixed-stroke SAI when you need variable end-stops for product changeovers. For load-holding without continuous air pressure, consider the SAIL or BSAI series, as this adjuster is not a lock. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ160X140-20 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 140 mm nominal stroke by up to 20 mm, resulting in a usable travel window of 120-140 mm for fine-tuning.
