Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-40
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 105mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-40
The AirTAC SAIJ160X105-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits you to dial back the nominal 105 mm travel by up to 40 mm. This yields a usable end-position window spanning 65 to 105 mm, enabling precise machine setup without swapping hardware. Built with a robust 40 mm carbon steel rod and M36x2 thread, it handles heavy loads with a push force of 10053 N at 0.5 MPa.
The extruded aluminum barrel incorporates sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. It carries PT tapered port threads and uses the standard SAIJ mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). The rear adjuster acts purely as a travel stop for end-position tuning, meaning it will not hold a load dynamically without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-40 Is Used
Press Tonnage Calibration
Dial in the exact 65 to 105 mm travel window during press setup to accommodate varying material thicknesses without repositioning the entire actuator.
Heavy Product Diversion
Adjust the retract stopper on the fly to handle different pallet widths on a high-thrust conveyor routing line.
Machine Changeover
Fine-tune the end-of-stroke position during product family changeovers to minimize setup downtime and avoid adding external mechanical stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-40 the Right Cylinder?
Select this 160 mm bore cylinder when an application requires high thrust—stepping up from a 125 mm bore yields a significant jump from 6136 N to 10053 N of push force at 0.5 MPa. An adjustable stroke is chosen here over a fixed SAI cylinder when you need variable end-stops to accommodate product size changeovers on a line. For load-holding without continuous air supply, this adjuster will not function as a lock; you must integrate an external rod lock or pilot-operated check valve, or select a BSAI clamp-lock variant.
When configuring your ISO 15552 replacement, verify the 160 mm bore, 105 mm nominal stroke, 40 mm adjustment range, PT port threads, and the required mounting bracket. Because the 105 mm stroke is relatively short, external side-load guides are less critical than on longer travels, but the heavy 40 mm rod still provides excellent resistance to deflection under offset loads.
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 SAIJ160X105-40 FAQ
At a 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. Maximum thrust reaches 2050 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 105 mm nominal stroke by up to 40 mm, creating a usable travel window of 65 to 105 mm. It is a travel stop, not a lock, so it cannot hold the load without live air pressure.
