About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX115-50S
The AirTAC SAIJ32X115-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 115 mm travel back by up to 50 mm, creating a highly flexible 65 to 115 mm usable stroke window.
This variant includes an -S magnet for position sensing via CMSE reed or DMSE electronic switches fitted into the dual-side sensor grooves. It features a SUS420J2 stainless steel rod for improved corrosion resistance and uses PT tapered port threads (G1/8). The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position and does not hold the load without live air pressure.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX115-50S Is Used
Variable End-Stop Tuning
Dial in the exact retract distance between 65 and 115 mm during commissioning to perfectly match new product sizes without changing the cylinder.
Machine Changeover Setup
Quickly reconfigure the stroke window on packaging or sorting lines, using the rear stopper to adapt end positions for different material lengths.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX115-50S the Right Cylinder?
The 50 mm adjustment range is ideal for machine setups requiring variable end-stops during product changeovers, eliminating the need to physically swap out a fixed-stroke SAI cylinder for each new job.
Because the rear screw simply dials in the travel end, it cannot lock the load pneumatically; for true drop-prevention without live air, consider an AirTAC SAIL or BSAI series. For ISO 15552 dimensional interchangeability, match the 32 mm bore, 115 mm stroke, 50 mm adjustment, PT G1/8 ports, and -S magnet. As with any stroke exceeding 100 mm, ensure adequate external guiding to protect the 12 mm rod from excessive side-loading.
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 SAIJ32AX115-50S FAQ
The rear adjuster screw lets you shorten the nominal 115 mm stroke by up to 50 mm, providing a usable travel window of 65 to 115 mm. It acts as a travel stop and does not function as a lock to hold the load without air pressure.
