About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-50S
The AirTAC SAIJ32X170-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel anywhere between 120 and 170 mm. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered G1/8 ports.
Because this configuration includes a magnet (-S), it directly supports AirTAC CMSE reed and DMSE solid-state sensors housed within the dual-side sensor grooves. The rear adjuster functions strictly as a mechanical stop for product changeovers, meaning it will not hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-50S Is Used
Machine Changeover
Dial in the 120-170 mm travel window during product size transitions to set new end stops without physically swapping the cylinder.
End-Position Tuning
Use the rear screw to fine-tune the retract position during initial setup, absorbing mechanical tolerances on the assembly line.
Corrosive Environments
Leverage the SUS304 stainless steel rod and 402 N thrust for reliable actuation in washdown or chemical exposure areas.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-50S the Right Cylinder?
Choose this adjustable model over a fixed-stroke SAI when you need variable end-position tuning at commissioning without adding external stops. If you need higher thrust, stepping up to a 40 mm bore yields 628 N at 0.5 MPa. For exact ISO 15552 replacement matching, verify the 32 mm bore, 170 mm nominal stroke, 50 mm adjustment range, PT port thread, and the -S magnet option.
With a 170 mm stroke, the 12 mm rod and M10x1.25 thread handle moderate side loads, but an external guide is recommended for heavy lateral forces. Note that the mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. If your application requires true load-holding without continuous air, consider the SAIL or BSAI series instead.
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 SAIJ32BX170-50S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 170 mm stroke by up to 50 mm, providing an effective travel window of 120 to 170 mm. It does not lock the load without live air pressure.
It provides 402 N of push force and 345 N of pull force at 0.5 MPa. At the maximum operating pressure of 1.0 MPa, it can deliver up to 82 kgf of thrust.
