Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-75
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-75 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 SAUJ100X90-75
The AirTAC SAUJ100X90-75 is a double-acting, single-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you trim the working stroke by up to 75 mm, giving a usable extension range of 15 to 90 mm for precise machinery setup without buying a new actuator. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions at each end.
This 100 mm bore generates 3927 N push and 3681 N pull force at 0.5 MPa, peaking at 7068 N push at 0.9 MPa. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore. For sizing, a safe working load is roughly 2356 N (about 60% of the 0.5 MPa push force), translating to a 200 kg vertical lift with a 2:1 margin. Note this SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-75 Is Used
Press Fit Tuning
Dialing in exact insertion depth for delicate bearing presses where a 15 to 90 mm stroke window prevents over-travel.
Variable Depth Sealing
Adjusting the extend end position on packaging lines to accommodate different carton heights without changing actuators.
Prototyping Fixtures
Testing clamping force and reach on R&D fixtures where the final stop position must be empirically set on-site.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X90-75 the Right Cylinder?
When sizing this actuator, compare both directions: the 80 mm bore yields 2513 N push at 0.5 MPa, while the 100 mm bore provides 3927 N. Choose the SAUJ over a fixed SAU when your assembly requires minor extend-length tweaks on-site. The 75 mm adjust window is ideal for dialing in exact end positions. Mounting options include Basic, FA flange, and LB foot, matching the AirTAC SC series. Because this SKU lacks the -S magnet, it cannot support position sensing. For strokes of 300 mm or longer, always use external guides 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 SAUJ100X90-75 FAQ
At 0.5 MPa it provides 3927 N push and 3681 N pull force. Push rises to 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 75 mm via the external stop screw, yielding a 15 to 90 mm usable range.
The external stop screw mechanically limits the piston extension, letting you set the end position on-site. This stop is not a load lock. A plain cylinder drifts on air loss, and 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.
