Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-75S
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-75S 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 SAUJ100X90-75S
The AirTAC SAUJ100X90-75S 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 75mm, giving a usable range of 15-90mm. The 90mm nominal length serves as the maximum extension. It features a 1/2 inch port and an M20x1.5 rod thread.
This 100mm bore generates 3927N push and 3681N pull at 0.5MPa. The safe working load is roughly 2356N, allowing a vertical lift of about 200kg with a 2:1 margin. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore. The -S suffix means a built-in magnet supports CMSG, DMSG, or EMSG sensors. An external stop sets the end position but does not lock the load.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-75S Is Used
Press Fit Tuning
Dialing in exact insertion depth for bearing presses. The 75mm stop screw window allows operators to fine-tune the extend position on the floor without changing cylinders.
Variable Height Sealing
Adapting to different carton sizes on a packaging line. The external stop quickly sets the precise 15-90mm extend distance needed for consistent flap sealing.
Prototype Actuation
Testing end-of-arm tooling reach during machine development. Engineers can mechanically trim the stroke by up to 75mm to verify clearance before finalizing designs.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-75S the Right Cylinder?
Size both ways: the 80mm bore neighbor provides 2513N push at 0.5MPa, while this 100mm bore yields 3927N. Choose SAUJ over a fixed SAU when your machine assembly requires minor extend length tweaking without buying new hardware. The 75mm adjust window is ideal for dialing in exact end positions. Basic, FA, and LB mounts are available, sharing compatibility with the AirTAC SC series only. The -S magnet supports electronic or reed switches. For strokes at or over 300mm, use a guide to prevent side-load damage.
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 SAUJ100X90-75S FAQ
At 0.5MPa it provides 3927N push and 3681N pull. Push force is 5497N at 0.7MPa and 7068N at 0.9MPa, with a theoretical max of 801kgf at 1.0MPa. The 90mm nominal extend stroke can be shortened by up to 75mm via an external stop screw, yielding a 15-90mm usable range.
The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG position switches. The external stop screw only sets the end position; it is not a load lock. Without live air the piston drifts, so use an external rod lock or pilot-operated check valve for held loads.
