Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-40
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 100mm 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 SAIJ32X100-40
The AirTAC SAIJ32X100-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 60-100mm usable travel window. Delivering 402N of push force at 0.5 MPa, it utilizes a 12mm carbon steel rod with an M10x1.25 thread and a PT G1/8 port. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This adjustable-stroke design allows you to fine-tune the retract end position during commissioning without adding external stops. The rear adjuster acts purely as a travel stop and works alongside the 27mm variable air cushions to decelerate the load; it does not hold the load without live air pressure. For position holding, consider a SAIL or BSAI variant.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-40 Is Used
Machine Changeover
Dial in the 60-100mm travel window during product size changes without swapping out the entire cylinder assembly.
End-Stop Calibration
Fine-tune the retract position at commissioning to prevent crashes, using the rear screw rather than external shims.
Variable Positioning
Adjust the effective stroke on the fly for automated test fixtures requiring flexible end-stop locations.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-40 the Right Cylinder?
Choose this 32mm bore when you need precise end-position tuning on the fly, stepping up from smaller compact units or down from a 40mm bore (which provides 628N push force at 0.5 MPa) if you need higher thrust. The SAIJ32X100-40 is ideal for applications requiring a variable end-stop rather than a fixed-stroke SAI cylinder. To match an ISO 15552 replacement, confirm the 100mm nominal stroke, 40mm adjustment range, PT G1/8 port, and your required mounting style from the available Basic, FA, LB, TC, FTC, TCM1, and TCM2 options. Since this unit lacks the -S magnet option, it does not support CMSE or DMSE sensors.
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 SAIJ32X100-40 FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At 0.7 MPa, the push force increases to 563N.
The rear adjuster allows you to shorten the 100mm nominal stroke by up to 40mm, creating a usable travel window of 60-100mm. The adjuster acts as a mechanical stop for end-position tuning and is not a locking device.
