About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX425-30S
The AirTAC SAIJ32X425-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 395-425 mm usable travel window by allowing you to trim the 425 mm nominal stroke back by up to 30 mm. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa. The extruded aluminum barrel features sensor grooves on both sides for flexible switch placement.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance and uses PT tapered port threads. The rear adjuster acts strictly as a mechanical stop to fine-tune the end position during commissioning; it is not a lock and will not hold the load without live air pressure. For position holding without continuous air, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX425-30S Is Used
Variable End-Stop Tuning
Dial in the exact 395 to 425 mm travel distance during machine commissioning without swapping out the entire cylinder body.
Product Size Changeover
Quickly adapt the retract end-position on a packaging line when handling slightly different package dimensions on the fly.
Fixture Calibration
Use the 30 mm rear adjustment screw to fine-tune clamping distances on test fixtures, ensuring precise contact without external spacers.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX425-30S the Right Cylinder?
Choose this 32 mm bore model when your application requires 402 N of thrust at 0.5 MPa but might need slight end-position tuning without adding external stops. If your process demands higher clamping power, stepping up to the 40 mm bore yields 628 N of push force. An adjustable stroke is preferred over a fixed SAI cylinder when you need precise variable end-stops for product changeovers. To replace an ISO 15552 cylinder, match the 32 mm bore, 425 mm stroke, 30 mm adjustment, PT port, and -S magnet. Because the stroke is 425 mm, ensure adequate external guiding to prevent side-loading damage to the rod and thread.
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 SAIJ32BX425-30S 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 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster allows you to shorten the 425 mm nominal stroke by up to 30 mm, creating a 395-425 mm travel window. The adjuster functions as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
