Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X260-40S
The AirTAC Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X260-40S is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 260mm 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 SAUJ32X260-40S
The AirTAC SAUJ32X260-40S is a double-acting single-rod profile cylinder with a 32mm bore and a 1/8 inch port. An external stop screw lets you shorten the extend stroke by up to 40mm on-site, giving a usable working stroke of 220 to 260mm. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore. This -S model includes a piston magnet for CMSG, DMSG, or EMSG sensors.
In the 32mm class, this cylinder delivers a push force of 402N and a pull force of 345N at 0.5MPa. A practical computed insight is a safe working load of about 241N, roughly 60 percent of the 0.5MPa push figure. For vertical lifting, expect a safe capacity around 20kg with a 2:1 margin. The adjustable air cushion is 21mm at each end, and the rod end thread is M10x1.25.

Where the Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X260-40S Is Used
Adjustable Parts Ejector
Tunes the extend stroke by up to 40mm on-site to hit varying part ejection distances without remachining the fixture.
Variable Depth Stop
Provides a field-adjustable end position for locating different workpiece heights on a shared machining fixture.
Carton Flap Folder
Dials in the folding stroke precisely for changing box sizes, relying on the 220 to 260mm extend range.
Is the Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X260-40S the Right Cylinder?
Size this 32mm bore against its neighbors: a 40mm bore gives 628N push at 0.5MPa, while smaller options lack the adjustability profile. Choose the SAUJ over a fixed SAU when your machine assembly requires on-site tuning of the extend end position without buying a new cylinder. The 40mm adjust window is ideal for dialing in exact clamping or ejection distances. Basic, FA flange, and LB foot mountings are available, with mounting compatibility matching the AirTAC SC series only. Because this is an -S SKU, you can directly fit CMSG, DMSG, or EMSG switches. At 260mm stroke, mount it to minimize side loads and use external guide rails to prevent rod binding.
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 SAUJ32X260-40S FAQ
At 0.5MPa the push force is 402N and pull is 345N. Push is 563N at 0.7MPa, 724N at 0.9MPa, and the theoretical max is 82kgf at 1.0MPa. The external stop screw allows you to shorten the extend stroke by up to 40mm, yielding a usable extend range of 220 to 260mm.
No. A plain cylinder drifts on air loss or when the valve is centered. The 21mm adjustable air cushion only decelerates the piston near the end of travel, and the stop screw sets the end position but acts as no lock. For load holding, install an external rod lock or a pilot-operated check valve.
