About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X850-40S
The AirTAC SAIJ32X850-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 810 to 850 mm, allowing you to dial back the nominal 850 mm stroke by up to 40 mm during machine commissioning. This bore size generates 563 N of push force at 0.7 MPa.
Equipped with a standard carbon steel rod and a -S magnet, it integrates seamlessly with AirTAC CMSE reed and DMSE electronic sensors housed within the dual-side barrel grooves. The rear stopper acts purely as a travel end-deceleration device, so you must maintain live air pressure to hold a load. For true locking requirements, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X850-40S Is Used
Product Changeovers
Dial in the exact 810 to 850 mm travel window during line format changes without physically swapping out the cylinder.
Commissioning Calibration
Fine-tune the retract end-position by up to 40 mm at machine setup to perfectly align tooling without external stoppers.
Variable End Stops
Adjust the stroke on the fly for multi-format packaging lines that require slightly different travel distances per product.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X850-40S the Right Cylinder?
Choose this 32 mm bore when your application requires 563 N of thrust at 0.7 MPa and precise end-position tuning without adding external stops. If your setup demands less force, stepping down to a 20 mm bore yields 188 N of push at 0.5 MPa. This adjustable model is preferred over a fixed-stroke SAI cylinder when you need a variable end-stop to accommodate product changeovers or minor mechanical drift.
When ordering, specify the 850 mm stroke, 40 mm adjustment range, PT tapered port threads, and the -S magnet option. Because the 850 mm stroke is long relative to the 12 mm rod diameter, it is highly susceptible to side-loading; always use an external guide rail to prevent rod deflection and premature seal wear.
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 SAIJ32X850-40S FAQ
At an operating pressure of 0.7 MPa, this 32 mm bore cylinder produces 563 N of push force and 483 N of pull force. It can deliver up to 80 kgf at its maximum 1.0 MPa pressure rating.
The rear adjuster screw allows you to shorten the effective travel from 850 mm down to 810 mm. This creates a 40 mm adjustable window for fine-tuning the end position without replacing the cylinder.
