Airtac SAUJ100 Adjustable Cylinder SAUJ100X850-75S
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X850-75S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 850mm 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 SAUJ100X850-75S
The AirTAC SAUJ100X850-75S is a double-acting, single-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you trim the 850 mm nominal stroke down by up to 75 mm, yielding a usable range of 775 to 850 mm. The extruded aluminum profile 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 29 mm adjustable air cushions.
This 100 mm bore delivers a push force of 3927 N and pull of 3681 N at 0.5 MPa. A safe working load is roughly 2356 N, allowing a vertical lift of about 200 kg with a 2:1 margin. The -S suffix means a built-in magnet supports CMSG, DMSG, or EMSG sensors. For high-heat environments up to 150 C, Viton H seals are available.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X850-75S Is Used
Large Press Feeders
Pushes heavy stock into a press where the exact material length varies, using the stop screw to tune the final 75 mm of the extend position on-site.
Pallet Diverters
Handles oversized pallets on a conveyor, requiring field adjustment of the extend stroke to accommodate varying pallet widths without changing the actuator.
Vertical Lift Gates
Raises heavy access gates, using the 200 kg vertical lift capacity and the adjustable stop to set the precise open height during commissioning.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X850-75S the Right Cylinder?
When sizing this actuator, compare it against the 80 mm bore, which provides 2513 N push at 0.5 MPa, and ensure 3927 N is sufficient for your move. The 75 mm adjust window is ideal if your exact end position needs field tuning, saving you from buying a custom fixed-stroke SAU and adding an external stop. Basic, FA, and LB mountings are available, sharing compatibility with the AirTAC SC series. Because the stroke is 850 mm, use an external guide to prevent rod bending and manage side loads. The -S magnet enables electronic or reed position sensing.

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 SAUJ100X850-75S FAQ
At 0.5 MPa it pushes 3927 N and pulls 3681 N. Push force is 5497 N at 0.7 MPa, 7068 N at 0.9 MPa, and the theoretical max is 801 kgf at 1.0 MPa. The 850 mm nominal extend stroke can be shortened by up to 75 mm on-site via the external stop screw, giving a usable range of 775 to 850 mm.
The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG position switches. The cylinder does not hold load on air loss; the piston drifts and the cushion only decelerates. For a locked load, use an external rod lock or pilot-operated check valve.
