About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX130-30S
The AirTAC SAIJ32X130-30-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 130 mm stroke that can be fine-tuned backward by up to 30 mm, yielding a practical 100-130 mm travel window for precise positioning. Delivering 345 N of pull force at 0.5 MPa, it fits light-duty tasks perfectly.
This variant is equipped with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for use with CMSE reed and DMSE electronic sensors. It uses tapered PT ports sized G1/8 and relies on a 27 mm air cushion at both ends to decelerate the load. The rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX130-30S Is Used
Machine Changeover
Dial in the 100-130 mm travel window during product size transitions to set new end stops rapidly without changing the cylinder.
Precision Setup
Fine-tune the retract position at commissioning using the rear screw, perfect for aligning delicate 32 mm bore assemblies.
Light-Duty Positioning
Leverage the 345 N pull force and SUS304 rod for controlled movement in food-grade or washdown manufacturing environments.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX130-30S the Right Cylinder?
Choose this 32 mm bore when an application requires exact end-position tuning during commissioning or product changeover without swapping hardware. If you need greater thrust, stepping up to a 40 mm bore increases the pull force to 528 N at 0.5 MPa. For fixed travel without the adjustment screw, the standard SAI series is the alternative. Because this is a 130 mm stroke, side-loading is moderate, but always ensure proper external guidance for long unsupported rods.
To match this ISO 15552 replacement exactly, verify the 32 mm bore, 130 mm nominal stroke, 30 mm adjustment range, PT G1/8 ports, and the -S magnet option. Remember that the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR. If your process requires holding a load without continuous air, consider the SAIL or BSAI locking cylinders instead.

- ✓ 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 SAIJ32BX130-30S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. The maximum operating pressure is 1.0 MPa.
The rear adjuster screw allows you to shorten the effective stroke from the nominal 130 mm down to 100 mm. This stopper only sets the travel end and does not lock the load without live air.
