About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX125-100
The AirTAC SAIJ32X125-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 125 mm travel by up to 100 mm. This creates a wide 25-125 mm usable stroke window, letting you fine-tune the retract end-position at commissioning without swapping out the barrel or adding external stops. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This variant uses a SUS304 stainless steel rod (option B) for superior corrosion resistance and ships with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE solid-state switches. Remember that the rear adjuster acts only as a mechanical travel stop to set deceleration; it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX125-100 Is Used
Machine Setup & Commissioning
Dial in the exact retract position from 25 to 125 mm during initial startup, eliminating the need for custom spacers or shims to achieve the perfect end-stop.
Product Size Changeover
Quickly adapt the cylinder travel on packaging lines when switching to a different product size, using the rear screw to modify the stroke without changing the cylinder.
Variable End-Stop Positioning
Set precise mechanical limits for lower-force assembly tasks, relying on the 402 N push capacity and the 100 mm adjustment window to meet changing dimensional requirements.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX125-100 the Right Cylinder?
Choose this 32 mm bore when your application needs 402 N of push force at 0.5 MPa, which is a step down from the 50 mm bore that provides 982 N. An adjustable stroke is ideal for product changeovers on a line where the exact end-stop varies, whereas a fixed SAI cylinder locks you into one dimension. For load-holding without continuous air pressure, this plain cylinder will not suffice; you would need to look at the SAIL or BSAI locking series instead.
This SAIJ32X125-100 configuration includes a 125 mm stroke, 100 mm adjustment range, PT port threads, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because it omits FB, CA, CB, and CR mounts, verify your frame interface matches this subset. The 12 mm rod and M10x1.25 thread handle moderate side loads, but any long unsupported travel still requires an external guide.

- ✓ 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 Adjustable Cylinder SAIJ32 SAIJ32BX125-100 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It operates at a speed range of 30-800 mm/s and uses a 12 mm diameter rod with an M10x1.25 thread.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel back from the 125 mm nominal stroke down to as little as 25 mm. This provides a 25-125 mm adjustable window for fine-tuning the end position at commissioning, but it does not lock or hold the load without live air pressure.
