About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX125-10S
The AirTAC SAIJ160X125-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling precise end-position tuning without external stops. It features a SUS304 stainless steel rod and an integrated magnet for position sensing. With a 125 mm nominal stroke, the external adjusting screw provides a 10 mm trim range, yielding a usable travel window of 115-125 mm for exact commissioning refinement.
Belonging to the 160 mm bore class, this pneumatic actuator generates 10053 N of pull force at 0.5 MPa and operates at speeds of 30-500 mm/s. It includes variable air cushions at both ends to manage deceleration, though the adjuster acts only as a travel stop and does not hold the load without live air pressure. The extruded aluminum barrel incorporates sensor grooves on both sides, compatible with CMSE reed and DMSE electronic switches.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|

| 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 SAIJ160BX125-10S Is Used
Machine Setup & Changeover
Dial in the 115-125 mm travel window during product size transitions on a packaging line without physically swapping out the actuator.
Precision End-Stop Tuning
Use the rear adjusting screw to fine-tune the retracted end position during commissioning, eliminating the need to bolt on external mechanical stops.
Heavy-Duty Positioning
Leverage the 10053 N pull force to move heavy tooling or materials, relying on the SUS304 rod for corrosion resistance in demanding industrial environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX125-10S the Right Cylinder?
Selecting this 160 mm bore actuator makes sense when your application requires the 10053 N pull force at 0.5 MPa, stepping up from a 125 mm bore that offers 5734 N. The adjustable stroke is chosen over a fixed SAI cylinder when you need fine end-position tuning during machine setup or product changeover, allowing you to dial in the 115-125 mm travel window precisely. For load-holding without continuous air pressure, this adjuster will not function as a lock, so you should explore an SAIL or BSAI series cylinder instead.
As an ISO 15552 replacement, match the 160 mm bore, 125 mm stroke, 10 mm adjustment, PT tapered port threads, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Because this model features a robust 40 mm rod and M36x2 thread, it handles high side loads well, though any long unsupported stroke still necessitates an external guide.
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 SAIJ160BX125-10S FAQ
The rear adjuster screw allows you to shorten the 125 mm nominal stroke by up to 10 mm, creating a usable travel window of 115-125 mm to fine-tune the retract end position at commissioning.
