About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX400-100S
The AirTAC SAIJ160X400-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 400 mm nominal stroke by up to 100 mm for a precise 300-400 mm usable travel window. It belongs to the 160 mm bore class, delivering substantial thrust with 10053 N pull force at 0.5 MPa and a maximum output of 2050 kgf at 1.0 MPa. This unit features a SUS304 stainless steel rod for corrosion resistance and includes a magnet for position sensing.
Because the adjustment mechanism acts purely as a mechanical stop at the retract end, it does not hold the load without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides, and the standard variable air cushions at both ends decelerate the heavy moving load. You can fine-tune the end position during commissioning without adding external stops or swapping the cylinder.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX400-100S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance within the 300-400 mm window during machine setup, allowing precise positioning of heavy fixtures without machining external stop blocks.
Product Size Changeover
Adapt automated lines to different product lengths by turning the rear adjuster, shifting the end position up to 100 mm to accommodate new part dimensions on the fly.
Heavy Load Deceleration
Rely on the 50 mm variable air cushions at both ends alongside the mechanical stop to safely bring high-inertia loads moving at 30-500 mm/s to a controlled halt.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX400-100S the Right Cylinder?
Choose this 160 mm bore cylinder when an application requires high force combined with a variable end-stop; for lower force needs, stepping down to the 125 mm bore yields 5734 N pull at 0.5 MPa. The SAIJ160X400-100-S is selected over a fixed SAI model when product changeovers require shifting the retract position within the 300-400 mm window. It uses a PT tapered port and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. Remember that the rear adjuster is a travel stop, not a lock; for fail-safe load holding without live air, use an external rod lock or point to the SAIL or BSAI series.
With a 400 mm stroke, the M36x2 rod and thread carry significant side-load capacity, but long unsupported strokes still require an external guide to prevent binding. The included magnet works directly with AirTAC CMSE reed and DMSE electronic sensors, and the unit is dimensionally interchangeable per ISO 15552.

- ✓ 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 SAIJ160BX400-100S FAQ
This 160 mm bore cylinder generates 10053 N pull force and 14074 N push force at 0.7 MPa. At the maximum operating pressure of 1.0 MPa, it achieves a peak output of 2050 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 400 mm nominal stroke by up to 100 mm, creating a 300-400 mm usable travel window. It only sets the end position and does not lock the load without live air pressure.
