About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-30
The AirTAC SAIJ160X145-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 115 to 145 mm without adding external stops. It delivers substantial thrust, pushing 14074N at 0.7 MPa and 18095N at 0.9 MPa, making it suitable for heavy-duty positioning tasks. The standard carbon steel rod and PT tapered port threads ensure robust mechanical and pneumatic connections.
Unlike a fixed-stroke SAI cylinder, this model uses an integrated rear stopper screw to dial in the exact retract position during commissioning or product changeover. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches, though this specific SKU is configured without a magnet. Remember that the adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-30 Is Used
Heavy Press Tuning
Dial in the exact 115 to 145 mm retract position during heavy press commissioning to accommodate material thickness variations without swapping cylinders.
Product Changeover
Quickly adjust the end-stop on automated assembly lines when switching to a new product size, using the 30 mm trim range to set new dwell positions.
Robotic Material Handling
Provides 14074N of push force at 0.7 MPa for moving heavy pallets or components, with a variable stroke to fine-tune the handoff distance.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-30 the Right Cylinder?
Choose this 160 mm bore cylinder when your application requires high force—such as the 10053N push force available at 0.5 MPa—and a variable end-stop within a 115-145 mm travel window. If your setup needs less thrust, stepping down to a 100 mm bore provides 3927N at 0.5 MPa, whereas moving up to a 200 mm bore yields 15708N at 0.5 MPa. Because the stroke is 145 mm, no external guide is strictly required for side-load support, but the 40 mm rod diameter handles greater bending stresses than smaller bores.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 145 mm stroke, 30 mm adjustment range, PT port threads, and carbon steel rod material. This model supports the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. If your process requires true load-holding without continuous air pressure, consider the SAIL air-released lock or BSAI clamp-lock cylinders instead of relying on the rear adjuster.

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 SAIJ160X145-30 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 30 mm. This creates a usable travel window of 115 to 145 mm, enabling precise end-position tuning at commissioning without adding external stops.
At an operating pressure of 0.5 MPa, this 160 mm bore cylinder provides 10053N of push force and 9425N of pull force. At 0.9 MPa, the push force increases to 18095N.
