Airtac Adjustable Cylinder SAIJ32 SAIJ32AX45-20S
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX45-20S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 45mm 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 SAIJ32AX45-20S
The AirTAC SAIJ32X45-20-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 25 to 45 mm usable travel window, allowing you to dial back the 45 mm nominal stroke by up to 20 mm during commissioning. Delivering 402 N of thrust and 345 N of pull force at 0.5 MPa, it fits compact actuation needs.
This variant includes a piston magnet for CMSE reed and DMSE electronic sensors, utilizing a PT tapered port and an SUS420J2 stainless steel rod. The extruded aluminum barrel omits tie-rods, and the rear adjuster acts purely as a travel stop, not a load lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX45-20S Is Used
Machine Setup Tuning
Dial in the exact 25 to 45 mm end-stop during commissioning to perfect a compact pick-and-place motion without swapping hardware.
Product Changeover
Quickly adjust the travel window on a packaging line when switching to a slightly shorter component format.
Variable End Stops
Use the rear stopper to set precise retraction limits for delicate clamping tasks requiring up to 402 N of force.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX45-20S the Right Cylinder?
Choose this 32 mm bore when you need precise end-position tuning without adding external stops; for higher force, stepping up to a 40 mm bore yields 628 N push at 0.5 MPa. The SAIJ32X45-20-S is selected over a fixed SAI when a variable end-stop is required for product changeovers.
It uses PT porting and the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, TCM2. Because the rear screw is only a stop, use SAIL or BSAI cylinders if you need to hold a load without live air pressure.
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 SAIJ32AX45-20S FAQ
The rear adjuster lets you shorten the 45 mm nominal stroke by up to 20 mm, creating a 25 to 45 mm usable travel window. It acts as a mechanical stop and does not hold the load without live air pressure.
Because it includes a piston magnet (-S), it works directly with AirTAC CMSE reed switches and DMSE electronic solid-state sensors mounted in the barrel's dual-side sensor grooves.
