Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-10
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-10 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 SAUJ100X90-10
The AirTAC SAUJ100X90-10 is a double-acting, single-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you shorten the nominal 90mm stroke by up to 10mm, yielding a usable 80-90mm window without buying a new actuator. It features a 1/2" port, an M20x1.5 rod thread, and 29mm adjustable air cushions at each end.
Built with an extruded aluminum profile barrel, this unit is physically shorter than an ISO 15552 cylinder of the same bore. It delivers a push force of 3927N and pull of 3681N at 0.5MPa. For sizing, the safe working load is roughly 2356N (60% of the 0.5MPa push), and it can vertically lift about 200kg with a 2:1 safety margin. Note this SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-10 Is Used
Press Fit Tuning
Allows exact 0-10mm field adjustment of the extend stroke to dial in precise bearing press-fit depth without swapping actuators.
Carton Flap Folding
Provides high-force folding arms where the exact 80-90mm movement must be tweaked on-site to accommodate varying corrugated box heights.
Workpiece Clamping
Delivers up to 801kgf clamping force while permitting a 10mm external stop adjustment to compensate for fixture wear or part variance.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-10 the Right Cylinder?
When sizing this 100mm bore, compare it against the 80mm option: the 80mm yields 2513N push at 0.5MPa, while this 100mm provides 3927N, scaling up to 7068N at 0.9MPa. Choose the SAUJ over a fixed SAU when you need final end-position tuning during machine commissioning. The 10mm adjust window is ideal for fine-timing tool contact. Mounting is via Basic, FA, or LB styles, matching the AirTAC SC series. Since this non-S SKU has no magnet, add external sensors if detection is needed. For this 90mm stroke side-load is minimal, but always guide the load for longer strokes.
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 SAUJ100X90-10 FAQ
At 0.5MPa it provides 3927N push and 3681N pull. Push increases to 5497N at 0.7MPa, 7068N at 0.9MPa, and a theoretical max of 801kgf at 1.0MPa. The nominal 90mm extend stroke can be shortened by up to 10mm via an external stop screw, giving an 80-90mm usable window.
This SKU lacks a magnet and cannot accept magnetic switches. It also does not hold loads on air loss; the piston drifts and the 29mm cushions only decelerate near stroke end. For load holding, use an external rod lock or pilot-operated check valve.
