About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX125-75
The AirTAC SAIJ160X125-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 125 mm travel by up to 75 mm. This yields a highly flexible 50-125 mm usable stroke window, perfect for dialing in exact end positions during machine commissioning without swapping out the entire actuator.
This configuration features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific unit lacks a magnet for CMSE or DMSE switches. The rear screw functions purely as a travel stop to set deceleration, not as a lock, meaning it will not hold a load without live air pressure.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX125-75 Is Used
Heavy Press Tuning
Fine-tune the exact bottoming position of a heavy press during setup. The 50-125 mm travel window allows operators to adjust crush depth without machining new spacers.
Product Changeover Stops
Act as an adjustable end-stop on a conveyor handling varying pallet sizes. The 75 mm adjustment range lets operators quickly reconfigure the line for different product lengths.
Variable Stroke Ejection
Control the ejection stroke of heavy parts from a mold. The rear stopper can be dialed back to prevent ejecting parts too far when running shorter batches.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX125-75 the Right Cylinder?
Choose this 160 mm bore actuator when an application demands heavy thrust up to 10053 N at 0.5 MPa combined with variable end-stop positioning. The adjustable stroke is ideal for product-size changeovers on a line, whereas a fixed-stroke SAI cylinder is better suited for dedicated, single-purpose stations.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 125 mm nominal stroke, 75 mm adjustment range, PT port threads, and SUS304 rod material. Note that SAIJ supports a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. Because the nominal stroke is 125 mm, side-load is minimal, but the heavy 40 mm rod and M36x2 thread handle robust loads effectively.
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 SAIJ160BX125-75 FAQ
At a maximum 1.0 MPa, it can deliver up to 2050 kgf.
The rear adjuster acts as an external stopper, allowing you to shorten the effective stroke from its 125 mm nominal length down to as little as 50 mm. It sets the travel end and deceleration point but does not lock the load without live air pressure.
