Airtac SAUJ100 Adjustable Cylinder SAUJ100X75-75
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X75-75 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 75mm 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 SAUJ100X75-75
The AirTAC SAUJ100X75-75 is a double-acting, single-rod profile cylinder with an on-site extend stroke adjustment window of 75mm. An external stop screw lets you trim the working stroke down from the 75mm maximum to zero, providing exact end-position tuning without buying a new actuator. It features a 1/2 inch port, an M20x1.5 rod thread, and 29mm adjustable air cushions.
This 100mm bore unit delivers a push force of 3927N at 0.5MPa and 7068N at 0.9MPa. For sizing, the safe working load is roughly 2356N (about 60 percent of the 0.5MPa push figure), and it can manage a vertical lift of approximately 200kg with a 2:1 margin. The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore, and high-temperature Viton H seals can extend operation to 150C.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X75-75 Is Used
Press Fit Tuning
Allows operators to dial in the exact 0-75mm extend position for pressing bearings without changing hard stops.
Variable Depth Sealing
Adjusts the extend stroke on-site to match different carton heights for sealing heads.
Prototype Actuation
Provides a 100mm bore force class with a field-tunable end position for testing new automated fixtures.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X75-75 the Right Cylinder?
When sizing this actuator, compare the 100mm bore against the 80mm option, which provides 2513N push at 0.5MPa, and ensure your air supply can handle the 1/2 inch port volume. Choose this SAUJ model over a fixed SAU when your assembly requires manual extend length tuning during commissioning. The external stop screw sets the end position but does not lock the load; for load holding on air loss, add an external rod lock or pilot-operated check valve. Mounting options include Basic, FA flange, and LB foot, compatible with the AirTAC SC series. This SKU lacks the -S magnet, so it cannot accept CMSG or DMSG sensors. For strokes over 300mm, use external guides 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 SAUJ100X75-75 FAQ
This 100mm bore cylinder pushes 3927N and pulls 3681N at 0.5MPa, pushes 5497N at 0.7MPa, and 7068N at 0.9MPa. The theoretical max is 801kgf at 1.0MPa. The external stop screw allows you to shorten the extend stroke by up to 75mm on-site.
No, this specific SKU does not include the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG sensors. You would need to specify an -S model for magnetic sensing capabilities.
