About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-50
The AirTAC SAIJ160X140-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel between 90 and 140 mm without adding external stops. Utilizing a robust 40 mm carbon steel rod and an M36x2 thread, this 160 mm bore unit generates 14074 N of push force at 0.7 MPa, making it ideal for heavy-duty positioning tasks. The extruded aluminum barrel incorporates sensor grooves on both sides for straightforward detection integration.
Unlike a fixed-stroke SAI, the rear adjustment screw on this model lets you dial in the retract end-position precisely during commissioning or product changeover. The adjuster functions strictly as a travel stop to set deceleration alongside the 50 mm air cushions, meaning it will not hold the load without live air pressure. For applications requiring position holding without continuous pneumatic supply, an external rod lock or AirTAC SAIL model is necessary.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-50 Is Used
Heavy Press Tuning
Dial in the exact 90 to 140 mm press stroke during machine setup to accommodate varying material thicknesses without changing the cylinder.
Product Changeover Stops
Quickly adjust the retract end-position on automated lines when switching to a new product size, saving retooling time.
Assembly Actuation
Provide up to 14074 N of push force at 0.7 MPa for heavy assembly operations, fine-tuning the travel end to prevent over-travel.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-50 the Right Cylinder?
Choose this 160 mm bore if you need heavy thrust that exceeds the 5497 N push force at 0.7 MPa provided by the 100 mm variant, but do not require the massive 21991 N output of the 200 mm cylinder. The adjustable 90-140 mm travel window is highly advantageous on fabrication lines where end-stops must be tweaked for varying product dimensions, eliminating the need to physically swap cylinders for minor length changes.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 140 mm stroke, 50 mm adjustment range, PT tapered port thread, and standard carbon steel rod. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is under 300 mm, side-load stress is manageable, but you should still guide the load externally to prevent binding. Note that the rear stopper is not a lock; use a BSAI clamp-lock cylinder for failsafe load holding.
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 SAIJ160X140-50 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder generates 14074 N of push force and 9425 N of pull force. It can deliver a maximum of 18095 N push at 0.9 MPa.
The rear adjuster screw allows you to shorten the nominal 140 mm stroke by up to 50 mm, creating a usable travel window of 90 to 140 mm. This stopper sets the end position but does not lock the load without live air pressure.
