About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX125-10
The AirTAC SAIJ160X125-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end position during commissioning. It features a 160 mm bore and provides a usable travel window of 115-125 mm, letting you trim the nominal 125 mm stroke back by up to 10 mm without adding external stops.
Designed for heavy-duty applications, it operates at speeds of 30-500 mm/s and includes variable air cushions at both ends to decelerate massive loads smoothly. The extruded aluminum barrel integrates sensor grooves on both sides, and while this specific SKU lacks a magnet, adding one enables compatibility with AirTAC CMSE reed and DMSE electronic sensors. The rear adjuster functions strictly as a travel stop to set the retract position, not as a lock to hold the 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 SAIJ160BX125-10 Is Used
Heavy Press Tuning
Dial in the exact 115-125 mm retract position during machine setup to accommodate different material thicknesses without replacing the actuator.
Corrosive Forming
Utilize the SUS304 stainless steel rod in humid or washdown forming environments where a standard carbon steel rod would degrade.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX125-10 the Right Cylinder?
If your application needs less force, stepping down to a 125 mm bore yields 6136 N, but the 160 mm class is necessary for heavier payloads. The adjustable 10 mm window is ideal for product changeovers where exact retract distances vary slightly, saving the cost of swapping a fixed-stroke SAI cylinder. Remember that the rear screw and air cushions only define the travel end; for load-holding without live air, consider an AirTAC SAIL or BSAI cylinder.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 125 mm stroke, and 10 mm adjustment range. This unit features a PT tapered port thread and a SUS304 stainless steel rod. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 125 mm stroke is relatively short for this large bore, side-load stress is minimal, but external guides are still recommended for heavy off-center loads.
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 SAIJ160BX125-10 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from the nominal 125 mm down to 115 mm. This creates a 115-125 mm travel window for fine-tuning the retract end position at commissioning without needing external stops.
