Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-10S
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-10S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 90mm stroke, 1/2" 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 SAUJ100 Adjustable Cylinder SAUJ100X90-10S
The AirTAC SAUJ100X90-10S is a double-acting single-rod profile cylinder with an on-site stroke trim feature. An external stop screw lets you shorten the extend stroke by up to 10 mm, giving a usable working stroke of 80 to 90 mm. The 90 mm nominal length serves as the maximum travel. It features a 1/2 inch port and a 25 mm piston rod.
This 100 mm bore delivers substantial power: 3927 N push and 3681 N pull at 0.5 MPa, peaking at 7068 N push at 0.9 MPa. The safe working load is roughly 2356 N, allowing a 200 kg vertical lift with a 2:1 margin. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore. The -S suffix adds a piston magnet for CMSG, DMSG, or EMSG switches.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-10S Is Used
Press Fit Calibration
Inserting bearings where a 10 mm external stop adjustment dials in the exact bottoming force without remachining the fixture.
Divertor Gate Tuning
Actuating a routing flap where the 80 to 90 mm extend window is fine-tuned on-site to match varying package sizes.
Pallet Stop Positioning
Deploying a heavy pallet stop where the final 10 mm travel is set by the stop screw to accommodate pallet length variations.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-10S the Right Cylinder?
Size both ways: dropping to an 80 mm bore drops the 0.5 MPa push to 2513 N, while this 100 mm unit provides 3927 N. Choose the SAUJ over a fixed SAU when your machine assembly needs final end-position tuning without machining external stops. The 10 mm adjust window is ideal for minor mechanical alignment. Mounting options include Basic, FA flange, and LB foot, sharing compatibility with the AirTAC SC series. The -S magnet enables electronic or reed sensing. For strokes over 300 mm, ensure external guiding to prevent side-load wear.
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 SAUJ100 Adjustable Cylinder SAUJ100X90-10S FAQ
At 0.5 MPa it provides 3927 N push and 3681 N pull. Push rises to 5497 N at 0.7 MPa and 7068 N at 0.9 MPa, with a theoretical max of 801 kgf at 1.0 MPa. The 90 mm nominal extend stroke is the maximum; the external stop screw shortens it by up to 10 mm, yielding an 80 to 90 mm usable window.
The external stop screw mechanically limits the extend travel, setting the end position without requiring a new cylinder. The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG switches. The stop screw only sets position; it does not lock the load. For load holding on air loss, use an external rod lock or pilot-operated check valve.
