Airtac Adjustable Cylinder SAIJ32 SAIJ32AX60-20
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX60-20 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 60mm 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 SAIJ32AX60-20
The AirTAC SAIJ32X60-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to trim the nominal 60 mm stroke back by up to 20 mm. This yields a usable travel window of 40 to 60 mm for precise end-position tuning at commissioning. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa. The piston rod is constructed from SUS420J2 stainless steel, offering improved corrosion resistance compared to standard carbon steel.
The rear adjuster acts purely as a mechanical stop to set the retract distance and works alongside the variable air cushions at both ends. It does not lock the load or hold position without continuous live air pressure. The extruded aluminum barrel features sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches, though this specific SKU is not magnet-equipped. Mounting options are limited to the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX60-20 Is Used
Machine Changeover
Dial in the 40 to 60 mm retract stop during product-size changeovers without adding external shims or swapping cylinders.
Component Seating
Fine-tune the end position during commissioning to softly seat delicate components using the 27 mm cushion and rear stopper.
Adjustable End Stop
Set a precise variable end-stop for light-duty 402 N push operations where a fixed 60 mm stroke would be too rigid.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX60-20 the Right Cylinder?
Choose this 32 mm bore when an application requires 402 N of push force at 0.5 MPa but demands on-the-fly end-stop adjustments rather than a fixed 60 mm stroke. If your setup needs less force, dropping down to a smaller bore changes the footprint entirely. If you require higher force, stepping up to a 40 mm bore provides 628 N of push at 0.5 MPa. The adjustable travel window is perfect for product-size changeovers on a line without swapping the cylinder.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 60 mm nominal stroke, 20 mm adjustment range, PT tapered port threads, and the SUS420J2 (code A) rod material. Because the stroke is only 60 mm, side loading is minimal, but always guide any external load to prevent rod binding. For applications that must hold a position without live air, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is not a lock.
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 SAIJ32AX60-20 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjusting screw lets you shorten the effective travel from the 60 mm nominal stroke down to 40 mm. This mechanical stop sets the retract end position but does not lock or hold the load without live air pressure.
