About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-100
The AirTAC SAIJ160X140-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the 140 mm nominal travel down to a highly flexible 40-140 mm usable window. This wide adjustment range allows operators to dial in exact end positions during commissioning or product changeovers without swapping out the cylinder or adding external mechanical stops. It delivers substantial thrust, generating 10053 N of push force and 9425 N of pull force at a 0.5 MPa operating pressure.
Built with a robust 40 mm carbon steel rod and M36x2 rod thread, this large-bore unit handles heavy loads and greater side loads than smaller bores. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic sensors if position feedback is later required. The rear stopper acts purely as a travel end deceleration device, meaning the cylinder cannot hold a load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-100 Is Used
Product Changeovers
Rapidly reconfigure the 40-140 mm stroke window on packaging lines without disassembling pneumatic stations when switching to a new product format.
Heavy Press Fitting
Apply up to 10053 N of push force at 0.5 MPa for assembling large components, using the rear adjuster to set precise pressing depth limits.
Adjustable End Stops
Provide variable physical end positions for heavy material handling, allowing the 40 mm cushion length to decelerate loads safely at the adjusted endpoint.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-100 the Right Cylinder?
Choose this 160 mm bore when an application requires the 10053 N push force at 0.5 MPa, stepping up from the 125 mm bore which provides 6136 N. The massive 100 mm adjustment range is ideal for machinery that processes varying product sizes, allowing the end-stop to be reconfigured rapidly on the fly. For load-holding requirements without continuous air pressure, this cylinder is insufficient as the adjuster is only a stop; consider the SAIL series with an air-released lock or the BSAI clamp-lock cylinder instead.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 140 mm stroke, 100 mm adjustment range, PT tapered port threads, and standard carbon steel rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR brackets. Because the 140 mm stroke is relatively short for this large bore, side-loading is less pronounced than on longer strokes, but an external guide is still recommended for heavy off-center loads.

- ✓ 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 SAIJ160X140-100 FAQ
At a 0.5 MPa operating pressure, this 160 mm bore cylinder provides a push force of 10053 N and a pull force of 9425 N. At the maximum 1.0 MPa pressure, it achieves a push force of 18095 N.
The SAIJ160X140-100 features a rear adjusting screw that allows you to shorten the effective stroke by up to 100 mm. This creates a usable travel window of 40 to 140 mm, enabling fine-tuning of the end position at commissioning without replacing the cylinder.
