About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-100S
The AirTAC SAIJ32X500-100-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 400-500 mm usable travel window by allowing you to dial back the nominal 500 mm stroke by up to 100 mm. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
Built for demanding environments, this variant uses a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance. It includes a magnet for position sensing, compatible with AirTAC CMSE reed and DMSE electronic switches mounted into the dual-side sensor grooves. The standard variable air cushions at both ends decelerate the piston, but the rear adjuster acts only as a travel stop, not a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-100S Is Used
Machine Changeovers
Dial in the exact end-stop during product size or format changes on a packaging line without replacing hardware.
End-Position Tuning
Fine-tune the retract stroke at commissioning to perfect seating against varying workpiece tolerances.
Adjustable Datum Setup
Establish a variable datum point on automated test fixtures where the effective travel needs on-site adjustment.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-100S the Right Cylinder?
Choose this adjustable-stroke model when your machine setup requires fine end-position tuning during commissioning or product changeovers without swapping out the entire cylinder or adding external stops. If your application needs less force, stepping down is not an option in the SAIJ range, but if you need higher thrust, the 40 mm bore offers 628 N at 0.5 MPa.
Because the 500 mm stroke is relatively long for a 32 mm bore, the 12 mm rod and M10x1.25 thread provide a sturdy interface, but an external guide is highly recommended to prevent excessive side-loading and rod deflection. For drop-in compatibility, match the 32 mm bore, 500 mm nominal stroke, 100 mm adjustment range, PT tapered port threads, and the -S magnet requirement. If you need true load-holding without live air pressure, consider the SAIL or BSAI series instead of relying on this adjuster.
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 SAIJ32AX500-100S 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 the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw lets you shorten the effective travel from the nominal 500 mm down to 400 mm. This creates a 400-500 mm adjustable window, allowing you to set the exact end-position at commissioning without adding external stops.
