About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-20
The AirTAC SAIJ32X260-20 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal stroke of 260 mm, but the integrated adjustment screw allows you to dial back the travel by up to 20 mm, creating a 240-260 mm usable window for precise end-position tuning at commissioning.
Delivering 402 N of push force at 0.5 MPa, this 32 mm bore unit features a 12 mm carbon steel rod with an SUS420J2 stainless steel option (code A) for improved corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, and the rear stopper acts purely as a travel deceleration point, not a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-20 Is Used
Machine Changeover
Fine-tune the 240-260 mm travel window during product size changeovers to set new end positions without adding external stops.
End-Position Tuning
Dial back the stroke by up to 20 mm during commissioning to perfect the mechanical timing without replacing the cylinder.
Assembly Line Setup
Use the rear adjuster to synchronize multiple 32 mm bore actuators across an automated assembly line for precise operational sync.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-20 the Right Cylinder?
Choose this SAIJ32X260-20 when your setup requires variable end-stops or machine changeover flexibility without swapping out the entire cylinder. If your application needs less force, stepping down is not an option from this size, but stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa for heavier demands. Since the 260 mm stroke is relatively long for a 32 mm bore, an external guide is recommended to prevent excessive side-loading on the 12 mm rod thread.
For an exact ISO 15552 replacement match, ensure you specify the 32 mm bore, 260 mm stroke, 20 mm adjustment range, PT tapered port thread, and the SUS420J2 (A) rod material. Remember that the rear adjuster only sets the travel end; it will not hold the load without live air pressure, so consider an SAIL or BSAI cylinder if true load-holding is required.
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 SAIJ32AX260-20 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.
The rear adjuster screw allows you to shorten the effective travel by up to 20 mm from the 260 mm nominal stroke, giving a usable 240-260 mm window to fine-tune the end position without changing the cylinder.
