About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-20
The AirTAC SAIJ32X195-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 175 to 195 mm, enabling precise end-position tuning during commissioning without external stops. Operating at 0.5 MPa, it delivers 402 N of push force and 345 N of pull force.
This variant incorporates a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and it supports a speed range of 30-800 mm/s. The rear adjuster acts purely as a travel stop for deceleration, meaning it cannot hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-20 Is Used
Machine Changeover
Dial in the 175-195 mm travel window during product size changes to set new end positions rapidly without replacing the cylinder.
End-Stop Calibration
Fine-tune the retract position during machine commissioning to perfect the physical stop location for delicate assembly tasks.
Variable Diverter
Adjust the stroke on the fly for diverter gates that must reposition slightly for different package sizes on a packaging line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-20 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N push force at 0.5 MPa; if you need less force, step down is not an option here as 32 is the smallest, but stepping up to a 40 mm bore provides 628 N. The adjustable 175-195 mm window is perfect for product changeovers where the exact end-of-stroke varies slightly, saving you from swapping cylinders. For an ISO 15552 replacement, match the 32 mm bore, 195 mm stroke, 20 mm adjustment, PT G1/8 port, and Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting. Since the stroke is under 300 mm, side-load stress on the 12 mm rod is moderate, though an external guide is still recommended for heavy lateral loads. If you need true load-holding without live 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 SAIJ32BX195-20 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N. The operational speed range is 30-800 mm/s.
The rear adjuster screw allows you to shorten the effective stroke by up to 20 mm, creating a 175-195 mm usable travel window. It acts as a mechanical stop to tune the end position, but it is not a lock and will not hold the load without live air pressure.
