About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX425-10S
The AirTAC SAIJ160X425-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 14074 N push force at 0.7 MPa and features a SUS304 stainless steel rod. The built-in magnet enables position sensing with CMSE reed and DMSE electronic switches. By turning the external rear screw, you can trim the effective travel, creating a 415-425 mm usable stroke window for fine-tuning the retract end position.
This adjustable stopper allows precise end-position tuning during commissioning without swapping the cylinder or adding external stops. The adjuster and the variable air cushions at both ends only decelerate and set the travel end; neither holds the load without live air. For load-holding without pressure, consider the SAIL or BSAI series. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX425-10S Is Used
Variable End-Stop Tuning
Dial in the exact 415-425 mm retract position during machine commissioning to perfect product ejection without machining external spacers.
Product-Size Changeover
Quickly adapt a packaging line to different carton lengths by adjusting the rear screw up to 10 mm, avoiding full cylinder swaps.
Heavy-Duty Positioning
Leverage the 14074 N push force at 0.7 MPa to move heavy pallets, using the rear stopper to fine-tune the final resting point.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX425-10S the Right Cylinder?
Choose this 160 mm bore when your application requires substantial thrust, such as 14074 N at 0.7 MPa, stepping up from a 125 mm bore that yields 8590 N at the same pressure. The adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers, whereas a fixed SAI cylinder locks you into a single dimension. Because the total stroke is 425 mm, an external guide is recommended to prevent side-loading on the 40 mm rod.
To replace this cylinder with an ISO 15552 equivalent, match the 160 mm bore, 425 mm stroke, 10 mm adjustment range, PT tapered ports, and the -S magnet. Remember that the rear adjuster acts purely as a travel stop, not a lock, so always maintain live air for position holding.
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 SAIJ160BX425-10S FAQ
At a 0.7 MPa operating pressure, this 160 mm bore cylinder generates a push force of 14074 N and a pull force of 9425 N. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the 425 mm nominal stroke by up to 10 mm, providing a usable travel window of 415-425 mm. This stopper sets the end position but does not lock the load without live air pressure.
