About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX600-20S
The AirTAC SAIJ32X600-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 580-600 mm usable travel window by dialing back the 600 mm nominal stroke up to 20 mm. Delivering 563 N of push force at 0.7 MPa, it is built with a SUS304 stainless steel rod (code B) and includes a magnet for position sensing.
The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed and DMSE electronic switches. Fitted with PT tapered port threads (G1/8), this 32 mm bore unit uses a 12 mm rod and M10x1.25 rod thread. The rear adjuster acts purely as a travel stop for end-position tuning, not a load lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX600-20S Is Used
Machine Changeover
Dial in the 580-600 mm end-stop during product size changes without swapping the cylinder or adding external stopper blocks.
Variable End-Stop Positioning
Fine-tune the retract stroke up to 20 mm at commissioning to perfectly align pusher plates on a packaging line.
Stainless Rod Actuation
Leverage the SUS304 rod and 402 N push force at 0.5 MPa for light-duty testing fixtures requiring precise travel limits.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX600-20S the Right Cylinder?
Select this 32 mm bore cylinder when you need a 580-600 mm stroke range and fine end-position tuning without adding external stops. If your application requires less force, dropping to a 25 mm bore reduces thrust, whereas stepping up to a 40 mm bore yields 879 N push at 0.7 MPa. For machine changeovers, the adjustable stopper allows quick end-position shifts versus a fixed-stroke SAI cylinder.
Because the 600 mm stroke creates a long unsupported rod, an external guide is recommended to prevent side-load wear. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. This standard profile cylinder does not hold loads without live air; for dead-drop protection, use an external rod lock, SAIL, or BSAI clamp-lock cylinder.

- ✓ 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 SAIJ32BX600-20S FAQ
The rear adjuster lets you shorten the 600 mm nominal stroke by up to 20 mm, providing a 580-600 mm usable travel window. The adjuster acts as a mechanical stop to fine-tune the end position and does not lock the load.
At 0.7 MPa operating pressure, the SAIJ32X600-20-S provides 563 N of push force and 345 N of pull force at 0.5 MPa. The maximum thrust is 82 kgf at 1.0 MPa.
