Airtac SAUJ100 Adjustable Cylinder SAUJ100X70-50
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X70-50 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 70mm 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 SAUJ100X70-50
The AirTAC SAUJ100X70-50 is a double-acting, double-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you shorten the 70 mm nominal stroke by up to 50 mm, yielding a usable working stroke of 20 to 70 mm. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions.
This non-magnet SKU cannot accept 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 position on air loss.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X70-50 Is Used
Press Fit Tuning
Allows operators to dial in the exact 20 to 70 mm extend distance for inserting bearings without swapping actuators.
Variable Diverter Arm
Adjusts the pusher stroke on-site to handle different package sizes on a packaging line.
Adjustable Stop Gate
Provides a field-tuned physical stop for pallets, letting maintenance shorten the extend stroke by up to 50 mm.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X70-50 the Right Cylinder?
Choose SAUJ over a fixed SAU when your machine assembly needs slight extend-length tuning without buying a new cylinder. Mounting options include Basic, FA flange, and LB foot, compatible with the AirTAC SC series. Because this SKU lacks the -S magnet, it cannot take CMSG or DMSG sensors. For this 70 mm stroke, side-load is minimal, but any application exceeding 300 mm stroke requires an external guide 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 SAUJ100X70-50 FAQ
Push force is 5497 N at 0.7 MPa and 7068 N at 0.9 MPa, with a theoretical max of 801 kgf at 1.0 MPa. The nominal extend stroke is 70 mm, and the external stop screw allows you to shorten it by up to 50 mm on-site, giving a 20 to 70 mm working window.
The external stop screw mechanically limits the piston extension to set the end position. It is not a load lock; the cylinder drifts on air loss and the 29 mm cushion only decelerates near the end. For load holding, use an external rod lock or pilot-operated check valve. Also, this non-S SKU lacks a magnet and cannot accept sensors.
