Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-40
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-40 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 SAUJ100X90-40
The AirTAC SAUJ100X90-40 is a double-acting single-rod profile cylinder with an on-site stroke trim. An external stop screw lets you shorten the extend stroke by up to 40 mm, giving a usable working range of 50-90 mm. The 90 mm nominal stroke serves as the maximum extension. It features a 1/2 inch port and an M20x1.5 rod thread.
This 100 mm bore class delivers a push of 3927 N and pull of 3681 N at 0.5 MPa. A computed buyer insight suggests a safe working load around 2356 N, which translates to a vertical lift capacity of roughly 200 kg with a 2:1 margin. The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore. It includes 29 mm adjustable air cushions and offers a Viton H high-temperature seal option up to 150 C.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-40 Is Used
Press Fit Tuning
Allows operators to dial in the exact 50-90 mm extend position for inserting bearings without changing hard stops.
Variable Carton Sealing
Adjusts the extend end point on the fly to accommodate different flap heights on a packaging line.
Tooling Setup Blocks
Provides a field-tunable mechanical stop for locating heavy welding fixtures within a 40 mm window.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-40 the Right Cylinder?
When sizing this actuator, look at neighboring bores: an 80 mm bore provides 2513 N push at 0.5 MPa, while this 100 mm unit hits 3927 N. Choose the SAUJ over a fixed SAU when your machine assembly requires minor extend length tweaks without buying a new cylinder. The 40 mm adjust window handles mechanical timing variations. Mounting options include Basic, FA flange, and LB foot, sharing compatibility with the AirTAC SC series only. This SKU lacks the -S magnet, so it cannot accept CMSG or DMSG sensors. For strokes at or above 300 mm, always use an external 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 SAUJ100X90-40 FAQ
At 0.5 MPa it provides 3927 N push and 3681 N pull. Push outputs are 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 nominal 90 mm extend stroke can be shortened by up to 40 mm via the stop screw, yielding a 50-90 mm usable range.
The external stop screw mechanically sets the extend end position but is not a load lock. A plain cylinder drifts on air loss or when a valve is centered; the 29 mm air cushion only decelerates the piston near the end. For secure load holding, install an external rod lock or pilot-operated check valve. This non-S SKU cannot accept magnetic sensors.
