Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X145-100S
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X145-100S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 145mm stroke, 3/8" 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 SAUJ80 Adjustable Stroke Cylinder SAUJ80X145-100S
The AirTAC SAUJ80X145-100S is a double-acting single-rod profile cylinder with an on-site stroke adjustment window of 100mm. You can trim the extend stroke from the 145mm maximum down to 45mm via an external stop screw. It features a 3/8 inch port, an M20x1.5 rod thread, and 28mm adjustable air cushions. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore.
This 80mm bore generates 2513N push and 2268N pull at 0.5MPa, scaling to 4523N push at 0.9MPa. For sizing, the safe working load is roughly 1508N (about 60 percent of the 0.5MPa push force), translating to a 128kg vertical lift with a 2:1 margin. The -S suffix means a built-in magnet is present for CMSG, DMSG, or EMSG sensors.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X145-100S Is Used
Variable Depth Boring
Machining stations that need field-tuning of the extend stroke to accommodate different material thicknesses without swapping cylinders.
Adjustable Carton Sealing
Packaging lines handling varied box heights use the 100mm stop screw window to precisely set the pressing depth on the fly.
Tiered Pallet Positioning
Warehousing systems that push loads to multiple pallet tiers by mechanically limiting the extend stroke via the external stop.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X145-100S the Right Cylinder?
When sizing this unit, look at the neighboring bores: the 63mm bore yields 1559N push at 0.5MPa, while the 100mm bore yields 3927N. Choose the 80mm bore when your application demands exactly 2513N push at 0.5MPa. Select this SAUJ model over a fixed-stroke SAU cylinder when your machine build requires field-tuning the extend end position without buying new hardware. The 100mm adjust window lets you refine the stroke on-site. Mounting options include Basic, FA flange, and LB foot brackets, compatible with the AirTAC SC series. The -S option provides a piston magnet for electronic or reed switches. For strokes at or above 300mm, always use external guide rails to prevent side-load damage.
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 SAUJ80 Adjustable Stroke Cylinder SAUJ80X145-100S FAQ
This 80mm bore cylinder delivers 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, 4523N at 0.9MPa, and a theoretical max of 513kgf at 1.0MPa. The external stop screw allows you to shorten the extend stroke by up to 100mm, giving a usable range of 45-145mm.
An external stop screw mechanically sets the extend end position, letting you trim the stroke on-site. This stop is not a load lock. A plain cylinder drifts on air loss and the 28mm air cushions only decelerate near the stroke end. To hold a load securely, install an external rod lock or a pilot-operated check valve.
