About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-50S
The AirTAC SAIJ160X900-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 850 to 900 mm. Built for heavy-duty tasks, it generates 14074 N of push force at 0.7 MPa. The barrel features an extruded aluminum profile with sensor grooves on both sides, distinguishing it from traditional tie-rod constructions.
This specific SKU features a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes a magnet (-S) for CMSE reed or DMSE electronic solid-state sensors. The rear stopper screw lets you dial in the exact end position during commissioning without adding external stops. Note that this adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-50S Is Used
Heavy Press Tuning
Fine-tune the 850-900 mm retract end-stop precisely during machine commissioning to accommodate different material thicknesses in large forming presses.
Product Changeover
Quickly adjust the stroke window by up to 50 mm on packaging lines when switching to larger product sizes, avoiding the need to physically swap out the entire cylinder.
Long-Stroke Positioning
Utilize the robust 14074 N push force and SUS304 rod to move heavy pallets or fixtures over a 900 mm travel distance while integrating DMSE solid-state sensors for precise end detection.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-50S the Right Cylinder?
Selecting this 160 mm bore cylinder makes sense when your application requires substantial thrust, such as 14074 N push at 0.7 MPa, but might need a smaller footprint if the load is lighter; stepping down to a 125 mm bore yields 8590 N push at 0.7 MPa. The adjustable stroke is ideal for product changeovers, allowing you to fine-tune the retract position on the fly instead of swapping out a fixed-stroke SAI cylinder. For exact ISO 15552 replacement matching, verify the 900 mm stroke, 50 mm adjustment range, PT tapered ports, and the -S magnet option.
Because this model features a 900 mm stroke, the 40 mm diameter rod and M36x2 thread will still experience leverage forces under load. An external guide mechanism is highly recommended to prevent excessive side-loading and premature seal wear over such a long travel distance. If your process requires the load to be held mechanically without continuous air pressure, consider the SAIL lock or BSAI clamp-lock variants instead of relying on the rear adjuster.
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 SAIJ160BX900-50S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N. The maximum push force is 18095 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 50 mm, creating a usable travel window of 850 to 900 mm. This stopper sets the end position but does not lock the load without live air pressure.
