About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-20
The AirTAC SAIJ32X700-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel by up to 20 mm. This creates a usable 680-700 mm travel window, letting you fine-tune the retract end-position at commissioning without swapping the cylinder or adding external stops. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, making it suited for lighter-duty work.
This variant uses a SUS420J2 stainless steel rod (code A) for corrosion resistance and features PT tapered port threads (G1/8). The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is built without a magnet. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-20 Is Used
Product Changeover
Dial in the 680-700 mm retract position on the fly when switching between product lengths on a packaging line, avoiding the need to swap cylinders or rework fixtures.
Variable End Stops
Set precise rejection distances for varying package sizes on a conveyor without adding bulky external hard stops at the end of the travel path.
Machine Setup
Fine-tune the final end-position during initial commissioning to perfectly time a 700 mm stroke cycle, compensating for minor mechanical tolerances.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-20 the Right Cylinder?
Choose this 32 mm bore model when your application requires a 700 mm stroke but needs precise end-position tuning within a 680-700 mm window during machine setup or product changeover. If your process demands higher thrust, stepping up to a 40 mm bore provides 628 N of push force at 0.5 MPa. Because the stroke is 700 mm, the 12 mm rod and M10x1.25 thread require external guidance to prevent excessive side-load damage on the unsupported rod.
Select an adjustable-stroke SAIJ over a fixed SAI when you need variable end-stops without mechanical rework. For drop-in ISO 15552 replacement, match the 32 mm bore, 700 mm stroke, 20 mm adjustment, PT G1/8 ports, SUS420J2 rod, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting set. Remember that the rear adjuster is a stop, not a lock; for true load-holding without live air, use an external rod lock or pilot-operated check valve.

- ✓ 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 SAIJ32AX700-20 FAQ
At an operating pressure of 0.5 MPa, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
The rear adjuster screw lets you shorten the effective stroke by up to 20 mm, providing a usable travel window of 680 to 700 mm. This mechanical stopper sets the retract end-position but does not lock or hold the load without continuous live air pressure.
