Airtac SAUJ40 Adjustable Stroke Cylinder SAUJ40X260-100
The AirTAC Airtac SAUJ40 Adjustable Stroke Cylinder SAUJ40X260-100 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 260mm stroke, 1/4" 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 SAUJ40 Adjustable Stroke Cylinder SAUJ40X260-100
The AirTAC SAUJ40X260-100 is a double-acting, single-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you shorten the 260 mm nominal stroke by up to 100 mm, yielding a usable 160 to 260 mm working range. It features a 1/4" port, an M12x1.25 rod thread, and 21 mm adjustable air cushions at each end. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore.
In the 40 mm bore class, this unit delivers 628 N push and 528 N pull force at 0.5 MPa, reaching 879 N push at 0.7 MPa. A practical computed insight: the safe working load is roughly 377 N, or about 32 kg for vertical lifting with a 2:1 safety margin. Choose this adjustable model over a fixed SAU cylinder when you need to dial in the exact end position without buying multiple units. Note this SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors.

Where the Airtac SAUJ40 Adjustable Stroke Cylinder SAUJ40X260-100 Is Used
Adjustable Clamping Press
Dial in the exact clamping distance on varying material thicknesses using the 100 mm stop screw window without changing the entire actuator.
Variable Length Diverter
Trim the extend stroke on-site to route different package sizes on a conveyor line, adapting the reject arm position quickly.
Custom Height Positioning
Set precise vertical stops for stacking or lifting platforms where the target height changes between production runs.
Is the Airtac SAUJ40 Adjustable Stroke Cylinder SAUJ40X260-100 the Right Cylinder?
When sizing this 40 mm bore actuator, compare it against the 32 mm bore if your load is light, or step up to the 50 mm bore for heavier thrust. At 0.5 MPa, the 32 mm offers 402 N push, the 40 mm provides 628 N push, and the 50 mm yields 982 N push. Select the SAUJ over a standard SAU when your machine build requires field tuning of the extend endpoint. The 100 mm adjust window is ideal for prototyping or accommodating varied part sizes. Mounting options include Basic, FA flange, and LB foot styles, compatible with the AirTAC SC series. Because this SKU has no -S magnet, it cannot support magnetic sensing. For the 260 mm stroke, ensure adequate side-load guidance to prevent uneven piston 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 SAUJ40 Adjustable Stroke Cylinder SAUJ40X260-100 FAQ
At 0.5 MPa it provides 628 N push and 528 N pull force. Push force is 879 N at 0.7 MPa, 1130 N at 0.9 MPa, and the theoretical max is 128 kgf at 1.0 MPa. The nominal 260 mm extend stroke can be shortened by up to 100 mm via an external stop screw, giving a 160 to 260 mm usable range.
No. The external stop screw only sets the end position; it is not a load lock. The 21 mm adjustable air cushion merely decelerates the piston near the end of travel. If you need to hold a load vertically on air loss, you must add an external rod lock or a pilot-operated check valve.
