About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-100
The AirTAC SAIJ160X950-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers massive thrust, providing 18095N of push force at 0.9 MPa, making it suited for heavy-duty automation. The built-in rear stopper allows you to fine-tune the effective travel anywhere within an 850-950 mm window without swapping the physical cylinder.
This variant is configured with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Because the nominal stroke is 950 mm, an external guide rail is strongly recommended to prevent excessive side loading on the piston rod during extended travel.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-100 Is Used
Heavy Fixture Positioning
Provides the immense force needed to shift heavy machining fixtures, with a 100 mm adjustment window to accommodate varying part envelopes.
Pallet Changeover Systems
Allows operators to quickly reconfigure the end-stop position for different pallet sizes on a transfer line without changing the cylinder hardware.
Large Assembly Presses
Delivers reliable linear motion for large-scale assembly stations, fine-tuning the travel distance during setup to guarantee perfect component mating.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-100 the Right Cylinder?
Choose this 160 mm bore when an 80 mm bore (providing 4523N push at 0.9 MPa) cannot generate enough force for your heaviest fixtures. The 100 mm adjustment range is ideal for production lines running multiple product sizes, letting you dial in the exact end-of-stroke position during commissioning rather than machining custom external stops. Remember that the rear adjuster functions only as a travel stop; it does not hold the load without live air pressure. For fail-safe load holding, consider an external pilot-operated check valve or the SAIL series.
To replace an ISO 15552 cylinder, match the 160 mm bore, 950 mm stroke, 100 mm adjustment, PT port thread, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). This unit omits the FB, CA, CB, and CR mounts. No magnet is specified, so position detection requires external sensors.
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 SAIJ160BX950-100 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder generates 18095N of push force and 14074N of pull force. It can operate up to a maximum pressure of 1.0 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the 950 mm nominal stroke down to 850 mm. This creates a 100 mm usable window for fine-tuning end positions during commissioning without adding external stops.
