Airtac SAUJ50 Adjustable Stroke Cylinder SAUJ50X750-30S
The AirTAC Airtac SAUJ50 Adjustable Stroke Cylinder SAUJ50X750-30S is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 750mm stroke, 1/4" 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 SAUJ50 Adjustable Stroke Cylinder SAUJ50X750-30S
The AirTAC SAUJ50X750-30S is a double-acting, single-rod profile cylinder with a 50 mm bore and a 750 mm maximum stroke. An external stop screw lets you shorten the extend stroke on-site by up to 30 mm, yielding a usable range of 720 to 750 mm. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 1/4" port, an M16x1.5 rod thread, and a built-in magnet for CMSG, DMSG, or EMSG sensors.
This bore delivers 982 N push and 825 N pull at 0.5 MPa. A safe working load is roughly 589 N, allowing a vertical lift of about 50 kg with a 2:1 margin. The stop screw dictates the end position but does not lock the load; for fail-safe holding on air loss, add an external rod lock or pilot-operated check valve. Because the 750 mm stroke invites rod bending, use an external guide to prevent side-load damage.

Where the Airtac SAUJ50 Adjustable Stroke Cylinder SAUJ50X750-30S Is Used
Gauge Positioning
Allows operators to fine-tune the 720 to 750 mm extend reach of an inspection gauge by up to 30 mm on-site to match varying product widths.
Transfer Diverter
Provides adjustable pusher extension on a conveyor line, letting maintenance shorten the stroke by 30 mm without replacing the cylinder.
Packaging Stopper
Sets a precise end-stop for varying carton sizes, using the external screw to dial in the exact extend position for each run.
Is the Airtac SAUJ50 Adjustable Stroke Cylinder SAUJ50X750-30S the Right Cylinder?
Select this 50 mm bore over a 40 mm unit (628 N push @0.5 MPa) if you need the extra force, or step up to a 63 mm bore (1559 N push @0.5 MPa) for heavier loads. Choose the SAUJ over a fixed SAU when your machine assembly requires on-site extend length tuning within the 30 mm window, avoiding the need to buy a new cylinder for minor position changes. It supports Basic, FA flange, and LB foot mounts, sharing mounting compatibility with the AirTAC SC series only. The -S suffix means a piston magnet is included for electronic or reed switches. With a 750 mm stroke, external guiding is essential to manage side loads and prevent rod bending.
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 SAUJ50 Adjustable Stroke Cylinder SAUJ50X750-30S FAQ
At 0.5 MPa it provides 982 N push and 825 N pull. Push force is 1374 N at 0.7 MPa, 1767 N at 0.9 MPa, and a theoretical max of 200 kgf at 1.0 MPa. The nominal 750 mm extend stroke can be shortened by up to 30 mm via the stop screw, giving a usable range of 720 to 750 mm. The 1/4" port and M16x1.5 rod are fixed for this bore.
The -S suffix indicates a built-in piston magnet for mounting CMSG, DMSG, or EMSG position sensors along the profile barrel. The external stop screw mechanically limits the piston travel to shorten the extend stroke on-site. This screw only sets the end position; it does not hold the load on air loss, so a pilot-operated check valve is needed for load holding.
