About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX220-10
The AirTAC SAIJ32X220-10 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 10 mm. This creates a precise 210-220 mm usable travel window, enabling fine end-position tuning at commissioning without swapping out the barrel or adding external stops. Delivering 402 N of push force at 0.5 MPa, it is built with an SUS420J2 stainless steel rod and uses PT tapered port threading.
The adjuster functions strictly as a mechanical stop and works alongside the variable air cushions at both ends to decelerate the piston. It does not lock the load without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides, and because no magnet is specified, position sensing via CMSE or DMSE switches is not enabled out of the box.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX220-10 Is Used
Machine Setup & Changeover
Dial in the exact 210-220 mm end position during line changeovers without disassembling the cylinder or adding external shims.
Variable End Stops
Fine-tune the retract position on the fly to accommodate minor variations in part dimensions during light assembly tasks.
Component Alignment
Adjust the travel limit precisely during commissioning to perfectly seat delicate components without overtravel.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX220-10 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa, but you need exact end-position flexibility during machine setup or product changeover. If your process demands higher force, stepping up to the 40 mm bore yields 628 N at the same pressure. Conversely, if you need less force, a smaller bore would be required. The rear adjuster lets you set variable end stops on the fly, a distinct advantage over a fixed-stroke SAI cylinder.
When specifying a replacement, match the 32 mm bore, 220 mm nominal stroke, 10 mm adjustment code, PT port thread, and SUS420J2 (A) rod material. Note that the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. Because the stroke is 220 mm, ensure your setup manages side loads with an external guide if the rod is unsupported.
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 SAIJ32AX220-10 FAQ
At an operating pressure of 0.5 MPa, 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 adjuster screw acts as a mechanical stop that lets you shorten the 220 mm nominal stroke by up to 10 mm. This provides a usable travel window of 210-220 mm, though it only decelerates the load and does not hold it without live air pressure.
