Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X450-30
The AirTAC Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X450-30 is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 450mm stroke, 1/8" 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 SAUJ32 Adjustable Stroke Cylinder SAUJ32X450-30
The AirTAC SAUJ32X450-30 is a double-acting single-rod profile cylinder with an on-site extend stroke adjustment window. You can shorten the 450 mm maximum stroke by up to 30 mm via the external stop screw, yielding a usable 420-450 mm extend range. It features a 1/8" port, an M10x1.25 rod thread, and 21 mm adjustable air cushions at each end.
This 32 mm bore profile barrel is purposefully shorter than a standard ISO 15552 unit of the same size, using a hard-anodized extruded aluminum body. It delivers 402 N push and 345 N pull at 0.5 MPa, peaking at 82 kgf. For sizing, the safe working load is roughly 241 N (about 60% of the 0.5 MPa push), translating to a vertical lift capacity of around 20 kg with a 2:1 safety margin. The unit lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X450-30 Is Used
Gripper Jaw Actuation
Drives a pneumatic gripper where the jaw opening requires precise on-site tuning within the 30 mm adjust window to grip varying part sizes.
Transfer Pusher
Pushes lightweight cartons between conveyor lanes, using the stop screw to dial in the exact push distance for different box widths.
Carton Flap Folder
Folds packaging flaps on a filling line, allowing operators to shorten the extend stroke by up to 30 mm to accommodate different carton profiles.
Is the Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X450-30 the Right Cylinder?
When sizing this actuator, look at the neighboring bores: a 40 mm bore offers 628 N push at 0.5 MPa, while this 32 mm provides 402 N. Choose the SAUJ32X450-30 over a fixed SAU when your machine assembly needs final end-position tuning of up to 30 mm without buying a different cylinder. It supports Basic, FA, and LB mountings, and is compatible with AirTAC SC series accessories. Because this is a non-magnetized SKU, it cannot take position sensors. With a 450 mm stroke, you must support side loads with an external guide to prevent rod bending. Note that the stop screw sets the end position; it is not a load lock.
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 SAUJ32 Adjustable Stroke Cylinder SAUJ32X450-30 FAQ
This 32 mm bore cylinder has a 1/8" port and delivers 402 N push / 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N at 0.9 MPa, and 82 kgf max at 1.0 MPa. The nominal 450 mm extend stroke is the maximum; the external stop screw lets you shorten it by up to 30 mm on-site, giving a 420-450 mm working range.
The external stop screw mechanically limits the extend end position but is not a load lock. A plain cylinder does not hold a load on air loss or valve centering—the piston drifts, and the 21 mm air cushions only decelerate near the stroke end. For a held load, use an external rod lock or pilot-operated check valve. Also, this SKU lacks a magnet and cannot take sensors.
