Airtac SAUJ100 Adjustable Cylinder SAUJ100X175-100S
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X175-100S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 175mm 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 SAUJ100X175-100S
The AirTAC SAUJ100X175-100S 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 100 mm, giving a usable range of 75-175 mm without buying a new unit. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 1/2" port, M20x1.5 rod thread, and 29 mm adjustable air cushions.
This 100 mm bore class delivers serious power: 3927 N push and 3681 N pull at 0.5 MPa, scaling to 7068 N at 0.9 MPa. A practical computed insight: the safe working load is roughly 2356 N (about 60% of the 0.5 MPa push force), translating to a vertical lift capacity of approximately 200 kg with a 2:1 safety margin. The -S suffix means a piston magnet is built-in for CMSG, DMSG, or EMSG position sensing.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X175-100S Is Used
Press Fit Tuning
Allows operators to dial in the exact 75-175 mm extend distance for inserting bearings or pins without changing the cylinder.
Variable Height Stops
Adjusts the extend end position on-site for packaging lines handling mixed product sizes requiring different push depths.
Diverter Positioning
Fine-tunes the diverting stroke length during commissioning to accommodate varying pallet widths on a conveyor.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X175-100S the Right Cylinder?
When sizing this actuator, look at both neighbors: the 80 mm bore gives 2513 N push at 0.5 MPa, while this 100 mm unit provides 3927 N. Choose the SAUJ over a fixed-stroke SAU when your machine design has unresolved end-position tolerances or requires field-tuning of the extend distance. The 100 mm adjust window is generous, letting you set the stroke anywhere from 75 to 175 mm. Mounting options include Basic, FA flange, and LB foot, with compatibility matching the AirTAC SC series. Because the -S magnet is present, you can directly mount reed or electronic sensors. For any stroke over 300 mm, ensure external guide rails to prevent side-load wear on the rod seals.
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 SAUJ100X175-100S FAQ
This 100 mm bore cylinder delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and 7068 N at 0.9 MPa. The theoretical maximum force is 801 kgf at 1.0 MPa. The nominal 175 mm extend stroke can be shortened by up to 100 mm using the external stop screw, providing a usable stroke range of 75-175 mm. It uses a 1/2" port and 29 mm adjustable air cushions.
The external stop screw mechanically sets the extend end position, but it is not a load lock. A plain cylinder does not hold a load if air pressure drops or the valve is centered; the piston will drift and the cushion only decelerates motion near the end. For secure load holding, you must add an external rod lock or a pilot-operated check valve. The -S suffix indicates a built-in magnet for CMSG, DMSG, or EMSG sensors.
