Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-30S
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-30S 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 SAUJ100X90-30S
The AirTAC SAUJ100X90-30S is a double-acting, single-rod profile cylinder with an external stop screw that lets you shorten the extend stroke by up to 30 mm on-site. The 90 mm nominal stroke is the maximum, yielding a usable extend window of 60-90 mm. It features a 1/2" port and an M20x1.5 rod thread. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore.
This 100 mm bore delivers substantial power: 3927 N push and 3681 N pull at 0.5 MPa, scaling to 7068 N push at 0.9 MPa. A computed buyer insight gives a safe working load around 2356 N, translating to a vertical lift capacity of roughly 200 kg with a 2:1 margin. The -S suffix means a built-in magnet for CMSG, DMSG, or EMSG sensors, and Viton H seals can raise the operating temperature to 150 C.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-30S Is Used
Press Fit Tuning
Allows operators to dial in the exact 60-90 mm extend position for inserting bearings without changing hard stops.
Variable Carton Flap Folding
Adjusts the extend stroke on-site to accommodate different box heights on a shared line.
Pallet Positioning Stops
Provides a field-adjustable end stop for indexing pallets of varying widths.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-30S the Right Cylinder?
Size this 100 mm bore against the 80 mm neighbor (2513 N push at 0.5 MPa) if your force needs are lower, or step up if 7068 N at 0.9 MPa is insufficient. Choose the SAUJ over a fixed SAU when you need on-site extend length tuning without buying a new cylinder. The 30 mm adjust window is ideal for final machine timing. Mounting options include Basic, FA, and LB, with compatibility matching the AirTAC SC series. Since the -S magnet is present, you can fit CMSG/DMSG/EMSG switches. For any stroke over 300 mm, ensure external guide rails to prevent side-load wear.
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 SAUJ100X90-30S FAQ
This 100 mm bore cylinder pushes 3927 N and pulls 3681 N at 0.5 MPa. It pushes 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 external stop screw shortens the extend stroke by up to 30 mm, giving a 60-90 mm usable window. It uses a 1/2" port and 29 mm adjustable air cushions.
The external stop screw mechanically limits the piston's extend travel, letting you trim the 90 mm stroke down by 30 mm on-site. This stop sets the end position but is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock or pilot-operated check valve for holding. The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG sensors.
