About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-30S
The AirTAC SAIJ32X650-30-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 650 mm stroke that can be fine-tuned backward by up to 30 mm, creating a usable travel window of 620 to 650 mm. This specific configuration includes a SUS420J2 stainless steel rod, PT tapered ports, and an integrated magnet for position sensing.
Operating at 0.5 MPa, the 32 mm bore yields 402 N of push thrust and 345 N of pull thrust. The extruded aluminum barrel incorporates sensor grooves on both sides, supporting CMSE reed and DMSE electronic switches. The rear adjuster functions purely as a mechanical stop to set the end position and does not lock the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-30S Is Used
Machine Changeover
Dial in the exact 620 to 650 mm end-stop during product size transitions without replacing the cylinder or adding external mechanical stops.
Variable End Positioning
Adjust the retract stroke by up to 30 mm to fine-tune where a part is released onto a conveyor at commissioning.
Sensor-Driven Assembly
Utilize the integrated magnet with DMSE electronic sensors to confirm actuation within the adjusted travel window on an assembly line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-30S the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your machine setup requires precise end-position tuning during commissioning or product changeover, avoiding the need to swap out a fixed-stroke SAI cylinder or bolt on external stops. If your application requires greater thrust, stepping up to the 40 mm bore provides 628 N of push force at 0.5 MPa. For an exact ISO 15552 replacement, match the 32 mm bore, 650 mm stroke, 30 mm adjustment, PT port thread, and the -S magnet requirement.
Because this model features a 650 mm stroke, which is well over 300 mm, the 12 mm diameter rod and M10x1.25 rod thread will be subjected to higher side loads if the load is unsupported. An external guide mechanism is strongly recommended to prevent rod binding and premature seal wear. Remember that the rear adjuster is a travel stop, not a brake; for load-holding without live air pressure, consider an SAIL or BSAI series cylinder.
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 SAIJ32AX650-30S FAQ
The rear adjuster screw acts as a mechanical stop that allows you to shorten the effective stroke by up to 30 mm. This gives the 650 mm nominal stroke a usable travel window of 620 to 650 mm, which is set during commissioning. The adjuster is a stop, not a lock, and does not hold the load without live air pressure.
At a standard operating pressure of 0.5 MPa, the SAIJ32X650-30-S generates 402 N of push force and 345 N of pull force. At the maximum operating pressure of 1.0 MPa, the push force reaches 82 kgf.
