Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-50S
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-50S 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 SAUJ100X90-50S
The AirTAC SAUJ100X90-50S is a double-acting single-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you trim the working stroke by up to 50mm, giving a usable range of 40-90mm. It uses a 1/2 inch port and an M20x1.5 rod thread. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore.
This 100mm bore delivers substantial power: 3927N push and 3681N pull at 0.5MPa, peaking at 7068N push at 0.9MPa. A safe working load is roughly 2356N, allowing a 200kg vertical lift with a 2:1 margin. The -S suffix means a built-in magnet for CMSG/DMSG/EMSG sensors. The 29mm adjustable air cushions decelerate the payload near stroke end.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-50S Is Used
Press Fit Dialing
Inserting bearings where the exact 40-90mm extend depth must be tuned on-site to avoid over-travel and damage.
Variable Stopper Arm
Acting as a heavy-duty lane diverter that adjusts its 50mm extend window to handle different package sizes on the fly.
Pallet Positioning
Pushing pallets into a tight alignment zone, using the stop screw to set the precise 100mm bore extend endpoint.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-50S the Right Cylinder?
Size this 100mm bore against the 80mm option (2513N push at 0.5MPa) or larger custom units if you exceed 7068N at 0.9MPa. Choose the SAUJ over a fixed SAU when your machine assembly requires minor extend-position tweaking without buying a new cylinder. The 50mm adjust window is ideal for dialing in exact endpoints. Mounting options include Basic, FA flange, and LB foot, sharing compatibility with the AirTAC SC series. Because the -S magnet is present, you can fit CMSG/DMSG/EMSG switches. For a 90mm stroke side-load is minimal, but always guide the tooling for longer strokes. The stop screw sets the end position but does not lock the load; use an external rod lock or pilot-operated check valve to hold position on air loss.
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 SAUJ100X90-50S FAQ
At 0.5MPa it provides 3927N push and 3681N pull. Push increases to 5497N at 0.7MPa and 7068N at 0.9MPa, with a theoretical max of 801kgf at 1.0MPa. The nominal 90mm extend stroke can be shortened by up to 50mm via the external stop screw, yielding a 40-90mm usable range.
The external stop screw mechanically limits the piston extension, letting you trim the endpoint without disassembling the cylinder. The -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG sensors along the 1/2 inch ported barrel for position detection.
