About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX375-50S
The AirTAC SAIJ32X375-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a 402N push force at 0.5 MPa and provides a usable travel window of 325 to 375 mm, letting you dial back the nominal 375 mm stroke by up to 50 mm during commissioning. The extruded aluminum barrel includes sensor grooves on both sides, and the -S magnet supports CMSE reed and DMSE electronic solid-state switches for exact position feedback.
This model uses a SUS304 stainless steel rod for corrosion resistance and a PT tapered port thread. The rear adjuster acts purely as a mechanical stop to fine-tune the end position without adding external stops, while the shared mounting interface uses the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX375-50S Is Used
Variable End-Stop Tuning
Dial the stroke back by up to 50 mm to set exact 325-375 mm travel limits during machine commissioning without external stopper blocks.
Product Size Changeover
Quickly adjust the retract position on packaging lines when handling different product lengths, saving downtime on manual refits.
Stainless Rod Actuation
Leverage the SUS304 rod and 402N force for light-duty positioning tasks in environments where standard carbon steel rods might face corrosion.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX375-50S the Right Cylinder?
Choose this 32 mm bore when you need 402N push force at 0.5 MPa (or 724N at 0.9 MPa) and a variable end-stop for product changeovers; step up to a 40 mm bore if your application requires 628N at 0.5 MPa. An adjustable stroke is preferred over a fixed SAI cylinder when you need to fine-tune travel during machine setup rather than swapping physical cylinders.
For an ISO 15552 replacement, match the 32 mm bore, 375 mm stroke, 50 mm adjustment, PT port, and -S magnet. Because the stroke is 375 mm, the 12 mm rod and M10x1.25 thread need an external guide to prevent side-load damage. The rear adjuster and air cushions decelerate the load but do not hold it without live air; for true load-holding, use a SAIL lock or BSAI clamp-lock cylinder.
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 Adjustable Cylinder SAIJ32 SAIJ32BX375-50S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402N of push force and 345N of pull force. At 0.9 MPa, the push force increases to 724N.
The rear adjuster screw lets you mechanically shorten the effective travel from the 375 mm nominal stroke down to 325 mm. It functions as a travel stop for end-position tuning and does not lock the load without live air pressure.
