About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX175-40
The AirTAC SAIJ32X175-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 135 to 175 mm, allowing you to dial in the exact retract position during commissioning without adding external stops. In the compact 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This variant features a SUS420J2 stainless steel piston rod for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX175-40 Is Used
Machine Changeover
Quickly adjust the 135-175 mm retract stop when switching between product sizes on a packaging line, eliminating the need to swap cylinders.
End-Position Tuning
Fine-tune the final position of a small pneumatic clamp during commissioning to ensure perfect alignment without external stopper blocks.
Assembly Stations
Dial in the exact travel distance for a pressing or seating operation, accommodating minor variations in part tolerances on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX175-40 the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when your application requires precise end-position tuning at setup or during product changeover, rather than relying on a fixed-stroke SAI. If your machine needs more clamping power, stepping up to the 40 mm bore increases the 0.5 MPa push force to 628 N. Conversely, the 32 mm bore is optimal where space is tight.
When matching this for an ISO 15552 replacement, verify the 175 mm stroke, 40 mm adjustment range, PT port, and the specific mounting accessory. Note that the rear adjuster acts only as a travel stop to set deceleration; it does not lock the load. For true load-holding without live air pressure, consider the SAIL or BSAI series instead.
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 SAIJ32AX175-40 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It operates at speeds ranging from 30 to 800 mm/s.
A rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 175 mm down to as little as 135 mm. It sets the travel end but does not hold the load without live air.
