About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-20S
The AirTAC SAIJ32X75-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 20 mm. This creates a usable 55-75 mm stroke window, letting you dial in the exact end position during commissioning without adding external stops. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This SKU ships configured with a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides, and the built-in magnet (-S) is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches for precise position feedback.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-20S Is Used
Machine Changeover
Dial in the 55-75 mm stroke window during product size changes to set new end positions rapidly without swapping the cylinder.
End-Stop Tuning
Fine-tune the retract position at commissioning using the rear adjuster, eliminating the need to bolt on custom external mechanical stops.
Assembly Positioning
Provides 402 N of push force at 0.5 MPa for clamping parts, with the 20 mm adjustment absorbing minor variations in workpiece dimensions.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX75-20S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa; stepping up to a 40 mm bore increases that to 628 N, while dropping to a smaller size limits your thrust. An adjustable-stroke cylinder is selected over a fixed-stroke SAI when you need variable end-stops for product changeovers or fine-tuning at machine setup. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure; for true load-holding without supply pressure, consider the SAIL or BSAI series. To match this ISO 15552 cylinder for a replacement, verify the 32 mm bore, 75 mm stroke, 20 mm adjustment, PT port thread, and the -S magnet requirement.
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 SAIJ32AX75-20S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. If operating at 0.7 MPa, the push force increases to 563 N.
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 75 mm stroke by up to 20 mm, providing a usable travel window of 55-75 mm. It sets the end position but does not lock or hold the load without live air pressure.
