Airtac Adjustable Cylinder SAIJ32 SAIJ32BX75-40S
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX75-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 75mm 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 SAIJ32BX75-40S
The AirTAC SAIJ32X75-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 35-75 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it is equipped with a SUS304 stainless steel rod and a PT tapered port. The integrated magnet supports position sensing.
Instead of machining external stops during product changeovers, technicians can dial in the end position directly at the cylinder. The rear adjuster functions purely as a travel stop and relies on live air to maintain the load. For true load-holding without pressure, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX75-40S Is Used
Product Changeovers
Quickly fine-tune the 35-75 mm travel window during line format changes without swapping out the entire actuator.
End-Stop Calibration
Dial in the exact retraction point during machine commissioning to prevent overshoot and ensure precise part placement.
Adjustable Ejection
Vary the ejection distance on the fly for different product sizes using the rear adjustment screw.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX75-40S the Right Cylinder?
Select this 32 mm bore when you need precise end-position tuning within a 35-75 mm window, rather than ordering a fixed-stroke SAI cylinder. If your application requires greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. To replace an ISO 15552 cylinder, match the 75 mm stroke, 40 mm adjustment, PT port, and -S magnet.
This model operates at speeds of 30-800 mm/s and uses a 12 mm rod with an M10x1.25 thread. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
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 SAIJ32BX75-40S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 82 kgf.
The rear adjuster allows you to shorten the 75 mm nominal stroke by up to 40 mm, creating a usable travel window of 35-75 mm. The adjuster acts as a mechanical stop and does not lock the load without live air pressure.
