About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-20S
The AirTAC SAIJ160X150-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers substantial thrust, providing 14074N of push force and 9425N of pull force at 0.7 MPa. Because this SKU carries a 20 mm adjustment code, you can fine-tune the effective travel window down from the 150 mm nominal stroke to any point within a 130-150 mm range during commissioning. This specific configuration includes a standard carbon steel piston rod and a magnetic ring for position sensing.
Instead of machining external stops or swapping out the entire barrel to achieve a precise end-position, the integrated rear screw lets you dial in the retract distance on the fly. The extruded aluminum profile features sensor grooves on both sides, allowing you to easily mount AirTAC CMSE reed or DMSE electronic solid-state switches. While the adjustable stopper and the variable air cushions at both ends handle end-of-stroke deceleration, remember that this mechanism acts only as a travel stop and does not hold the load without continuous live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-20S Is Used
Heavy Press Tuning
Dial in the exact 130-150 mm retract distance during press commissioning to accommodate different material thicknesses without adding external mechanical stops.
Tooling Changeover
Quickly adjust the end-position stop for automated machine setups when switching between product sizes on a heavy-duty fabrication line.
High-Force Positioning
Leverage the 14074N push force at 0.7 MPa to move heavy assemblies into place while using the rear screw to set the precise resting datum.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X150-20S the Right Cylinder?
Selecting this 160 mm bore model makes sense when your application requires heavy force that a 125 mm bore cannot provide, as the 160 steps up from 8590N to 14074N of push force at 0.7 MPa. Conversely, if you need even higher thrust, the 200 mm bore offers 21991N at the same pressure. The adjustable stroke is specifically beneficial for machine setups requiring variable end-stops or product-size changeovers, giving you the flexibility that a fixed-stroke SAI cylinder cannot. If your process demands true load-holding without live air, you would need to look at an external rod lock or a related SAIL pneumatic lock cylinder.
For an exact ISO 15552 dimensionally interchangeable replacement, match the 160 mm bore, 150 mm stroke, 20 mm adjustment, PT tapered port thread, and the -S magnet option. Mounting choices for this SAIJ series include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Although this 150 mm stroke is well within the 1500 mm maximum standard stroke for this bore, the substantial 40 mm rod diameter and M36x2 rod thread provide excellent structural rigidity and side-load resistance for heavy tooling.

- ✓ 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 SAIJ160X150-20S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a push force of 14074N and a pull force of 9425N. At its maximum rated pressure of 1.0 MPa, it can deliver up to 2050 kgf of thrust.
The rear adjuster screw allows you to shorten the nominal 150 mm stroke by up to 20 mm, creating a usable travel window of 130-150 mm. This stopper sets the retract end-position but does not lock or hold the load without continuous air pressure.
