Airtac Adjustable Cylinder SAIJ32 SAIJ32BX80-40S
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX80-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 80mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX80-40S
The AirTAC SAIJ32X80-40-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 80mm stroke that can be dialed back by up to 40mm, giving you a precise 40-80mm usable travel window for exact end-position tuning during commissioning. In this configuration, the piston rod is SUS304 stainless steel (code B), and the PT tapered port threads match the standard G1/8 interface.
Delivering 402N of push force at 0.5 MPa (345N pull), this 32mm bore unit uses a 12mm rod and M10x1.25 thread. The extruded aluminum barrel includes sensor grooves on both sides, and because this SKU includes a magnet (-S), it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches for position feedback. The rear adjuster acts purely as a mechanical stop to set the travel end and does not lock or hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX80-40S Is Used
Machine Changeover
Dial in the 40-80mm travel window during product size changes on a packaging line, fine-tuning the retract end position without installing external mechanical stops.
End-Position Trimming
Precisely set the retract stroke limit during initial commissioning to compensate for mechanical tolerances or sensor flag placement on a fixture.
Variable End Stops
Use the rear adjuster screw to alter the effective stroke for testing different gripping depths or clamping forces on a workholding station.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX80-40S the Right Cylinder?
Choose this 32mm bore adjustable cylinder when your machine setup requires variable end stops or frequent product changeovers, allowing you to trim the stroke from 80mm down to 40mm without swapping the cylinder or adding external stops. If your application requires greater thrust, stepping up to the 40mm bore neighbor yields 628N of push force at 0.5 MPa. Conversely, if you need a fixed travel without the adjuster, the standard SAI series is a simpler alternative.
When replacing an ISO 15552 cylinder, match the 32mm bore, 80mm stroke, 40mm adjustment range, PT port thread, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR. For any load-holding requirements without continuous air pressure, note that this cylinder's rear stop and air cushions do not function as a brake; instead, consider the SAIL (air-released lock) or BSAI (clamp-lock) series.

- ✓ 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 SAIJ32BX80-40S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 40mm. This gives the 80mm nominal stroke a usable travel window of 40-80mm, allowing fine-tuning of the retract end position at commissioning. It is a travel stop, not a lock, and cannot hold the load without live air pressure.
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At 0.7 MPa, the push force increases to 563N.
