About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX45-10
The AirTAC SAIJ32X45-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 10 mm. This creates a precise 35-45 mm usable stroke window, enabling exact end-position tuning at commissioning without adding bulky external stops. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, making it suitable for compact, lower-force motion tasks.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance and uses PT tapered port threading. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear adjuster acts strictly as a mechanical travel stop for deceleration and positioning; it does not hold the load without live air pressure, so a SAIL or BSAI lock variant is needed for true load-holding.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX45-10 Is Used
Machine Setup Tuning
Dial in the exact 35-45 mm end-position during commissioning to perfect a new assembly station's stopping point without swapping hardware.
Product Changeover
Quickly adjust the travel stop on a packaging line when switching to a slightly different product size, saving setup time.
Variable End-Stop Calibration
Fine-tune the retract position on a testing fixture to accommodate dimensional variations in incoming components.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX45-10 the Right Cylinder?
Choose this 32 mm bore if your application requires around 402 N of push force at 0.5 MPa. If you need less force, stepping down to a smaller bore changes the thrust output, while stepping up to a 40 mm bore increases push force to 628 N. The adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers, offering more flexibility than a fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 45 mm stroke, 10 mm adjustment range, PT port thread, and basic mounting interface. Because the stroke is under 300 mm, side-load stress is minimized, though the 12 mm rod and M10x1.25 thread still require an external guide for heavy lateral loads. This model does not include a magnet (-S), so it requires external sensing if position feedback is needed.
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 SAIJ32BX45-10 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 pressure of 1.0 MPa, it can deliver up to 82 kgf.
The rear adjuster screw lets you shorten the nominal 45 mm stroke by up to 10 mm, providing a usable travel window of 35 to 45 mm. This mechanical stop fine-tunes the end position but does not lock the load without live air pressure.
