Airtac SAUJ100 Adjustable Cylinder SAUJ100X85-75
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X85-75 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 85mm 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 SAUJ100X85-75
The AirTAC SAUJ100X85-75 is a double-acting, single-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you shorten the nominal 85mm stroke by up to 75mm, yielding a usable working stroke of 10 to 85mm. The extruded hard-anodized aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 1/2 inch port, an M20x1.5 rod thread, and 29mm adjustable air cushions.
This 100mm bore delivers robust force: 3927N push and 3681N pull at 0.5MPa, scaling to 7068N push at 0.9MPa. For sizing, the safe working load is roughly 2356N (about 60% of the 0.5MPa push figure), and it can manage a vertical lift of approximately 200kg with a 2:1 margin. Standard seals handle -20 to +70C, while a Viton H option extends this to 150C. Note this SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X85-75 Is Used
Press Fit Dialing
Inserting bearings where the exact depth needs field tuning. The 75mm window lets operators dial in the perfect 10 to 85mm extend position without swapping actuators.
Variable Length Diverter
Routing mixed package sizes on a line. The external stop screw adjusts the diverter stroke on-site to accommodate different carton lengths precisely.
Adjustable End Stop
Acting as a movable hard stop for pallets. The 100mm bore provides 3927N push force at 0.5MPa to halt loads, with the extend length trimmed to match pallet dimensions.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X85-75 the Right Cylinder?
When sizing, compare both neighbors: the 80mm bore provides 2513N push at 0.5MPa, whereas this 100mm unit hits 3927N. Choose the SAUJ over a fixed SAU when your machine assembly requires on-site extend length tuning without buying a new cylinder. The 75mm adjust window is ideal for dialing in exact end positions. Mounting options include Basic, FA flange, and LB foot styles, compatible with the AirTAC SC series. Since this specific SKU has no -S suffix, it cannot support magnetic sensing. For strokes at or over 300mm, always use an external guide to prevent side-load wear. Remember the stop screw sets position only; it is not a load lock.
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 SAUJ100X85-75 FAQ
At 0.5MPa it provides 3927N push and 3681N pull. Push force is 5497N at 0.7MPa, 7068N at 0.9MPa, and a theoretical max of 801kgf at 1.0MPa. The nominal 85mm extend stroke can be shortened by up to 75mm on-site via an external stop screw, giving a usable range of 10 to 85mm.
This SKU lacks a magnet, so it cannot accept magnetic sensors. A plain cylinder does not hold a load on air loss; the piston drifts and the cushion only decelerates near stroke end. For a held load, use an external rod lock or pilot-operated check valve.
