Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-30
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-30 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 SAUJ100X90-30
The AirTAC SAUJ100X90-30 is a double-acting single-rod profile cylinder with an on-site extend stroke adjustment. An external stop screw lets you shorten the nominal 90 mm stroke by up to 30 mm, yielding a usable 60-90 mm window. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same 100 mm bore. It features a 1/2" port, M20x1.5 rod thread, and 29 mm adjustable air cushions.
This bore delivers serious power: 3927 N push and 3681 N pull at 0.5 MPa, scaling to 7068 N at 0.9 MPa. For sizing, a safe working load is roughly 2356 N (about 60% of the 0.5 MPa push), and it can vertically lift around 200 kg with a 2:1 margin. The external stop sets the end position but is not a load lock; add an external rod lock or pilot-operated check valve if you need to hold a load without live air.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-30 Is Used
Press Fit Tuning
Allows operators to dial in the exact 60-90 mm extend position for seating bearings without machining hard stops.
Variable Format Flaps
Adjusts the extend end point on the fly to accommodate different carton depths on a packaging line.
Mold Pin Positioning
Trims the stroke precisely for inserting core pins of varying lengths before clamping.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-30 the Right Cylinder?
When sizing, look at the neighboring bores: an 80 mm bore gives 2513 N push at 0.5 MPa, while this 100 mm unit provides 3927 N. Choose the SAUJ over a fixed SAU when your machine assembly needs final end-position tuning within that 30 mm window without buying a new cylinder. Mounting options include Basic, FA flange, and LB foot, matching the AirTAC SC series. Because this SKU lacks the -S magnet, it cannot accept CMSG or DMSG sensors. For this 90 mm stroke side-load is minimal, but for any stroke over 300 mm add external guide rails. Operating pressure is 0.15-1.0 MPa.
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 SAUJ100X90-30 FAQ
At 0.5 MPa it pushes 3927 N and pulls 3681 N. Push is 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 30 mm via the external stop screw, giving a 60-90 mm working window. The stop sets end position and does not lock the load.
An external stop screw physically limits the piston travel to shorten the extend stroke on-site. Because this specific SKU does not have the -S magnet option, it cannot accept CMSG, DMSG, or EMSG magnetic switches. You would need to use external mechanical limit switches for position detection.
