About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX130-40S
The AirTAC SAIJ32X130-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 130 mm travel back by up to 40 mm, creating a precise 90-130 mm usable window for product changeovers. Delivering 402 N of push force at 0.5 MPa, it integrates a SUS304 stainless steel rod for corrosion resistance and includes a magnet for position sensing.
This adjustable-stop design eliminates the need to swap cylinders or bolt on external stops during fine end-position tuning. It features PT tapered port threads (G1/8), a 12 mm rod with an M10x1.25 thread, and variable air cushions at both ends. The extruded aluminum barrel carries sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX130-40S Is Used
Variable End-Stop Tuning
Dial in the exact 90-130 mm travel window during machine setup to accommodate varying material thicknesses without changing hardware.
Product Changeover
Quickly readjust the rear stopper on a packaging line when switching between different package sizes, minimizing downtime.
Sensor-Driven Positioning
Leverage the built-in magnet and dual sensor grooves to mount CMSE or DMSE switches for precise end-of-stroke confirmation.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX130-40S the Right Cylinder?
Choose this 32 mm bore when 402 N of thrust at 0.5 MPa is sufficient, stepping up to the 40 mm bore (628 N) if your payload increases. An adjustable stroke is selected over a fixed SAI cylinder when you need live commissioning fine-tuning or variable end-stops without mechanical rework. To match this ISO 15552 footprint, specify a 32 mm bore, 130 mm stroke, 40 mm adjustment, PT G1/8 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and the -S magnet option.
Because the stroke is 130 mm, side-load risks are minimal, but always ensure the M10 rod thread handles any angular misalignment. Remember that the rear adjuster is a travel stop, not a lock; the SAIJ does not hold loads without live air pressure, so for dead-end holding you should use a SAIL or BSAI 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 SAIJ32BX130-40S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder 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.
The rear adjuster acts as a mechanical stop that lets you shorten the 130 mm nominal stroke by up to 40 mm, providing a usable travel window of 90 to 130 mm. It only sets the travel end and does not lock the load without live air.
