Airtac SAUJ100 Adjustable Cylinder SAUJ100X80-50S
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X80-50S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 80mm 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 SAUJ100X80-50S
The AirTAC SAUJ100X80-50S is a double-acting single-rod profile cylinder with an external stop screw. You can shorten the extend stroke by up to 50 mm on-site, giving a usable working range of 30-80 mm from the 80 mm nominal maximum. It features a 1/2" port, an M20x1.5 rod thread, and 29 mm adjustable air cushions. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same 100 mm bore.
This 100 mm bore delivers serious thrust: 3927 N push and 3681 N pull at 0.5 MPa, climbing to 7068 N at 0.9 MPa. For payload 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 safety margin. The -S suffix means a piston magnet is built-in for CMSG, DMSG, or EMSG sensors. Note that the stop screw sets the end position but does not lock the load; you need an external rod lock or pilot-operated check valve to hold a load securely against air loss.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X80-50S Is Used
Press Fit Tuning
Allows operators to dial in the exact 30-80 mm extend position for inserting bearings without changing hard stops.
Variable Carton Sealing
Adjusts the extend stroke on-site to accommodate different box heights while maintaining 3927 N of sealing force.
Multi-Part Clamping
Trims the 80 mm stroke by up to 50 mm to clamp varying workpiece thicknesses securely on a single fixture.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X80-50S the Right Cylinder?
Choose this 100 mm bore when you need 3927 N of push force at 0.5 MPa (or 5497 N at 0.7 MPa). If your application only requires 2513 N at 0.5 MPa, step down to the 80 mm bore to save space and air. The 50 mm adjust window is ideal for machines needing precise end-position tuning without machining custom spacers. Select the SAUJ over a fixed-stroke SAU when you anticipate field adjustments or varying product sizes. Mounting options include Basic, FA flange, and LB foot styles, compatible with the AirTAC SC series. Because this model includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG sensors. At an 80 mm stroke, side-load is minimal, but for any setup exceeding 300 mm, always use external guide rails to prevent rod binding.
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 SAUJ100X80-50S FAQ
At 0.5 MPa it provides 3927 N push and 3681 N pull force, peaking at 7068 N push at 0.9 MPa. The 80 mm nominal extend stroke can be shortened by up to 50 mm on-site via the external stop screw, yielding a 30-80 mm usable range. It uses a 1/2" port and 29 mm adjustable cushions.
The -S suffix indicates a built-in piston magnet for direct mounting of CMSG, DMSG, or EMSG electronic or reed switches. The external stop screw physically limits the piston's extend travel to set the end position, but it is not a load lock; the cylinder will drift on air loss, so use an external rod lock for holding.
