About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X40-30S
The AirTAC SAIJ32X40-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 32mm bore, a 40mm nominal stroke, and a PT tapered port. The integrated -S magnet enables position sensing with AirTAC CMSE reed or DMSE electronic switches. By turning the rear screw, you achieve a usable travel window of 10-40mm, allowing precise end-position tuning without swapping hardware.
Delivering 402N of push force and 345N of pull force at 0.5MPa, this compact unit handles light-duty positioning. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Remember that the rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure; for dead-air locking, consider an SAIL or BSAI variant.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X40-30S Is Used
Product Changeover
Quickly dial in the 10-40mm travel window when switching between part sizes on a packaging line, using the rear screw to set new retract endpoints instantly.
Sensor Calibration
Leverage the -S magnet with DMSE electronic switches to verify exact positions while fine-tuning the stroke stop during initial machine commissioning.
Compact Clamping
Apply 402N of clamping force in tight assemblies where the 32mm profile footprint is required, adjusting the stroke to accommodate varying material thicknesses.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X40-30S the Right Cylinder?
Choose this 32mm bore when your application requires the smallest standard ISO 15552 footprint with 402N thrust at 0.5MPa. If your setup demands over 600N of push force, step up to the 40mm bore, which yields 628N. The 30mm adjustment range is ideal for dialing in exact end stops during machine commissioning or product changeovers, avoiding the need to fabricate external spacers. Unlike a fixed-stroke SAI cylinder, this adjustable model lets you trim the retract distance on the fly.
To match this exact replacement, specify: 32mm bore, 40mm nominal stroke, 30mm adjustment range, PT port threads, and the -S magnet option. Mounting is limited to the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. Because the 40mm stroke is short, side-load risks are minimal, but always ensure the M10x1.25 rod thread is aligned to prevent binding.

- ✓ 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 SAIJ32X40-30S FAQ
At 0.5MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At the maximum 1.0MPa pressure, it can deliver up to 82kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 40mm nominal stroke down to a minimum of 10mm. This creates a 10-40mm usable travel window for fine-tuning without replacing the cylinder.
