About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX30-20
The AirTAC SAIJ32X30-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster, engineered for applications requiring exact end-position tuning. By turning the external stopper screw, you can trim the nominal 30 mm stroke back by up to 20 mm, creating a highly precise 10 to 30 mm usable travel window without adding external stops. Delivering 402 N of push force at 0.5 MPa, it handles light-duty positioning with repeatable accuracy.
This variant is built with a SUS304 stainless steel piston rod for superior corrosion resistance and includes a PT tapered port thread. The extruded aluminum barrel integrates sensor grooves on both sides, allowing you to directly mount CMSE reed or DMSE electronic solid-state switches if position feedback is later required. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR brackets to streamline setup.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX30-20 Is Used
Machine Setup Calibration
Fine-tune the 10 to 30 mm travel window during initial machine commissioning to perfectly set the contact pressure on delicate components.
Product Size Changeover
Quickly adjust the retract end-stop by up to 20 mm when switching between slightly different product heights on a packaging line.
Light-Duty Positioning
Leverage the 402 N push force and SUS304 rod for precise, corrosion-resistant component placement in small assembly fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX30-20 the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when you need to dial in a specific end-of-stroke position during commissioning or product changeover, rather than committing to a fixed-stroke SAI variant. If your process demands higher clamping force, stepping up to a 40 mm bore increases thrust to 628 N at 0.5 MPa. Remember that the rear adjuster acts only as a mechanical stop and the air cushions manage deceleration; neither will hold a load unpressurized. For load-holding without live air, select a SAIL pneumatic lock or BSAI clamp-lock cylinder.
When matching ISO 15552 replacements, verify the 32 mm bore, 30 mm nominal stroke, 20 mm adjustment range, PT G1/8 port, and the required mounting bracket. Because the 12 mm rod diameter is relatively small, ensure your load is guided to prevent side-load wear, even on short 30 mm strokes.

- ✓ 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 SAIJ32BX30-20 FAQ
It features a rear stopper screw that lets you mechanically shorten the 30 mm nominal stroke by up to 20 mm, providing a usable travel window of 10 to 30 mm for precise end-position tuning.
At a standard 0.5 MPa operating pressure, the SAIJ32X30-20 provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
