About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX185-100S
The AirTAC SAIJ32X185-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position during commissioning. With a nominal 185 mm stroke and a 100 mm adjustment range, the usable travel window spans 85 to 185 mm, letting you dial in the exact retract distance without swapping hardware. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, operating at speeds between 30 and 800 mm/s.
This variant is built with a SUS304 stainless steel rod for corrosion resistance and includes a magnet for position sensing. The extruded aluminum barrel features sensor grooves on both sides, supporting AirTAC CMSE reed switches and DMSE electronic sensors. The rear adjuster acts purely as a mechanical stop to set the travel end and does not lock the load; for load-holding without live air pressure, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX185-100S Is Used
Machine Setup Calibration
Fine-tune the retract distance on packaging equipment during initial commissioning, adjusting the 85-185 mm travel window to achieve precise product indexing without hardware changes.
Product Changeover
Quickly adapt end-stops on a conveyor line when switching between different package sizes, utilizing the 100 mm adjustment range to accommodate varying product dimensions.
Variable End-Stop Positioning
Set exact clamping positions on small assembly fixtures where the 402 N push force is sufficient, relying on the rear stopper to establish the final position accurately.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX185-100S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa, stepping up from a smaller unit or down from a 40 mm bore that provides 628 N. The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, replacing the need for fixed-stroke SAI cylinders and external stops. Because this model features a PT tapered port thread and a 12 mm rod with an M10x1.25 thread, it handles basic loads but still requires an external guide if side loads are present.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 185 mm nominal stroke, 100 mm adjustment, PT port, and -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Since the stroke is under 300 mm, side-load concerns are minimal, but the 12 mm rod diameter still necessitates careful alignment to prevent 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 SAIJ32BX185-100S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers 82 kgf.
The rear adjuster screw allows you to shorten the effective stroke from its 185 mm nominal length by up to 100 mm, creating an adjustable travel window of 85 to 185 mm. The adjuster functions as a mechanical stop and does not hold the load without live air pressure.
