About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-75
The AirTAC SAIJ160X145-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel anywhere within a 70-145 mm window. Built with a robust 160 mm bore and a carbon steel piston rod, it delivers substantial thrust, generating 14074 N of push force at 0.7 MPa and up to 18095 N at 0.9 MPa. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback.
This adjustable variant uses a PT tapered G3/4 port and relies on variable air cushions at both ends to manage deceleration across its 30-500 mm/s operating speed range. The external rear stopper is strictly a travel-end adjuster, meaning it sets the precise end position during commissioning without acting as a load-holding brake or lock.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-75 Is Used
Heavy Press End-Tuning
Dial in the exact 70-145 mm travel window during heavy press commissioning to accommodate varying material thicknesses without external stops.
Product Size Changeover
Rapidly adjust the rear stopper on automated assembly lines when switching between different product sizes, minimizing machine downtime.
Variable Position Clamping
Provide adjustable clamping depth for heavy-duty fabrication tasks where the final position must be finely tuned to the workpiece.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X145-75 the Right Cylinder?
Choose this 160 mm bore when your application requires heavy thrust that exceeds the 10053 N push force of the smaller 125 mm variant at 0.7 MPa, but you do not need the maximum 15708 N push capacity of the 200 mm series. The 75 mm adjustment range is ideal for production lines running mixed product sizes, allowing you to dial in the exact end-stop without swapping cylinders or adding external mechanical stops.
If your process demands fail-safe load holding without live air pressure, a standard SAIJ will not suffice since the adjuster and cushions cannot hold a load; you should instead look at the SAIL or BSAI locking cylinder series. This SAIJ160X145-75 model features a PT tapered G3/4 port, a 50 mm cushion length, and utilizes the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) with no CA, CB, or CR brackets available.
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 SAIJ160X145-75 FAQ
At a standard 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 10053 N of push force.
The rear external adjuster screw allows you to shorten the nominal 145 mm stroke by up to 75 mm, creating a usable travel window of 70 to 145 mm. This stopper only sets the end position and does not lock the load without live air pressure.
