Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X700-20
The AirTAC Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X700-20 is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 700mm 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 SAUJ32X700-20
The AirTAC SAUJ32X700-20 is a double-acting, single-rod profile cylinder with an on-site extend stroke adjustment window of 20 mm. You can trim the usable extend stroke from 700 mm down to 680 mm using the external stop screw. It features a hard-anodized aluminum barrel, making it shorter than an ISO 15552 cylinder of the same 32 mm bore. The 1/8" port and M10x1.25 rod thread handle pneumatic supply, while adjustable 21 mm air cushions manage end-of-stroke deceleration.
This 32 mm bore generates 402 N push and 345 N pull at 0.5 MPa. A practical computed insight: the safe working load is roughly 241 N, and it can vertically lift about 20 kg with a 2:1 safety margin. Because this SKU lacks the -S magnet option, it cannot accept CMSG or DMSG sensors. Also, the stop screw dictates end position but does not lock the load; you need an external rod lock or pilot-operated check valve to hold position against air loss.

Where the Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X700-20 Is Used
Conveyor Diverter Setup
Requires precise 680 to 700 mm extend tuning to align packages accurately without reordering pneumatic hardware.
Warehouse Pusher Arm
Needs field stroke trimming to adjust the push distance for varying carton sizes on the fly.
Light Assembly Station
Demands exact end-position adjustment during machine commissioning to place components correctly.
Is the Airtac SAUJ32 Adjustable Stroke Cylinder SAUJ32X700-20 the Right Cylinder?
When sizing this actuator, compare it against the neighboring 40 mm bore, which raises push force to 628 N at 0.5 MPa. If your application only requires 402 N, this 32 mm bore is the optimal, lighter choice. Choose the SAUJ adjustable version over a fixed SAU when you need minor on-site extend length tuning without buying a new cylinder. The 20 mm adjust window is perfect for fine-tuning machine setups. Mounting options include Basic, FA flange, and LB foot, sharing compatibility with the AirTAC SC series. Since this is a non-magnetized SKU, you cannot mount magnetic sensors. Furthermore, at a 700 mm stroke, you must use external guides to prevent rod bending and manage side loads effectively.
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 SAUJ32X700-20 FAQ
At 0.5 MPa it provides 402 N push and 345 N pull. Push force is 563 N at 0.7 MPa, 724 N at 0.9 MPa, and the theoretical max is 82 kgf at 1.0 MPa. The external stop screw lets you shorten the 700 mm extend stroke by up to 20 mm on-site, yielding a usable range of 680-700 mm.
An external stop screw physically limits the piston's extend travel to set the end position. This mechanism only sets the stroke length; it is not a load lock. A plain cylinder drifts on air loss, and the 21 mm air cushions only decelerate the piston near the end. For secure load holding, install an external rod lock or pilot-operated check valve.
