Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X55-30S
The AirTAC Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X55-30S is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 55mm stroke, 1/8" air ports and adjustable end cushioning. Its hard-anodized aluminum-profile barrel is shorter than an ISO 15552 cylinder of the same bore, and it shares SC-series mounting accessories.

About the Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X55-30S
The AirTAC SAUJ32X55-30S is a double-acting single-rod profile cylinder with an external stop screw. You can trim the extend stroke by up to 30mm on-site, giving a usable working stroke of 25 to 55mm. It uses a 1/8 inch port and a 12mm rod with an M10x1.25 thread.
This 32mm bore generates 402N push and 345N pull at 0.5MPa. A safe working load is roughly 241N, allowing a 20kg vertical lift with a 2:1 margin. The extruded aluminum body is shorter than an ISO 15552 cylinder of the same bore. The built-in magnet supports CMSG, DMSG, and EMSG sensors.

Where the Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X55-30S Is Used
Probe Positioning
Testing stations needing precise probe contact depth can use the stop screw to dial in the exact 25 to 55mm extend position on-site.
Small Part Clamping
Ideal for clamping varied part sizes where the jaw travel requires field tuning to prevent crushing delicate components.
Sorting Diverter
Diverting lightweight packages on a conveyor benefits from the adjustable stroke to accommodate different product lengths.
Is the Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X55-30S the Right Cylinder?
Compare this 32mm bore against the 40mm option, which raises push force at 0.5MPa to 628N. If your application only needs 402N, the 32mm is the better fit. Choose the SAUJ over a fixed SAU when you need on-site length tuning without buying a new cylinder. The 30mm adjust window lets you set the exact extend end position. Basic, FA, and LB mounts are available, sharing compatibility with the AirTAC SC series. The -S suffix enables electronic position sensing. Since the stroke is under 300mm, side-load risks are minimal, but always guide the load externally.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/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 — same as SC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X55-30S FAQ
At 0.5MPa it provides 402N push and 345N pull. Push is 563N at 0.7MPa and 724N at 0.9MPa, with a theoretical max of 82kgf at 1.0MPa. The nominal stroke is 55mm, but the external stop screw allows you to shorten the extend stroke by up to 30mm on-site, yielding a 25 to 55mm working range.
The -S suffix means the piston has a built-in magnet for CMSG, DMSG, and EMSG switches. The stop screw and air cushions only set position and decelerate the piston; they do not hold the load on air loss. For secure load holding, install an external rod lock or pilot-operated check valve.
