About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-50
The AirTAC SAIJ160X145-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 145 mm stroke that can be dialed back by up to 50 mm, yielding a usable travel window of 95 to 145 mm. This built-in adjuster allows operators to fine-tune the retract end position at commissioning without adding external stops or physically swapping the cylinder. Delivering a robust 14074 N of push force at 0.7 MPa, it is built for heavy-duty positioning.
The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting. It uses a substantial 40 mm carbon steel rod with an M36x2 thread, providing excellent rigidity and high side-load resistance. The cylinder operates at 30-500 mm/s, features variable air cushioning at both ends, and utilizes PT (tapered) G3/4 ports for high flow requirements.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-50 Is Used
Heavy Press Tuning
Dial in the exact 95-145 mm retract position during machine commissioning to accommodate varying material thicknesses without external stopper blocks.
Product Changeover
Quickly adjust the end-of-stroke stop on packaging or forming lines when switching to a different product size, minimizing downtime between runs.
Robotic Material Handling
Leverage the 14074 N push force at 0.7 MPa to move heavy workpieces, using the 40 mm rod to withstand high side loads during transfer.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-50 the Right Cylinder?
Choose this 160 mm bore cylinder when your application requires substantial force—stepping up from a 125 mm bore yields 8590 N push at 0.5 MPa, while stepping down to a 100 mm bore offers only 5497 N at 0.7 MPa. The 50 mm adjustment range is ideal for machinery that undergoes frequent product-size changeovers, allowing the end-stop to be tuned precisely on the machine without replacing the actuator. For any stroke of 300 mm or more, an external guide is recommended to prevent rod binding, though this 145 mm model is well within standard unsupported limits.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 145 mm stroke, 50 mm adjustment, PT G3/4 ports, and the mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that this standard SAIJ variant does not include a magnet (-S); position sensing requires adding an -S suffix for CMSE reed or DMSE electronic switches. Remember that the rear adjuster acts only as a travel stop and the air cushion provides deceleration—neither holds the load without live air pressure. For fail-safe load holding, consider an AirTAC SAIL (air-released lock) or BSAI (clamp-lock) cylinder.

- ✓ 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 SAIJ160X145-50 FAQ
It features a rear adjusting screw that acts as a mechanical stopper, allowing you to shorten the effective stroke by up to 50 mm. This creates a usable travel window of 95 to 145 mm, enabling fine-tuning of the end position at commissioning without replacing the cylinder.
At a 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. It can deliver a maximum push force of 18095 N at 0.9 MPa.
