Airtac SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X400-100S
The AirTAC Airtac SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X400-100S is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 400mm 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 SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X400-100S
The AirTAC SAUJ63X400-100S is a double-acting single-rod profile cylinder with an on-site adjustable extend stroke. You can shorten the 400 mm nominal stroke by up to 100 mm via the external stop screw, yielding a 300 to 400 mm working window. It features a 63 mm bore, a 20 mm rod, and a 3/8 inch port.
This profile barrel is notably shorter than an ISO 15552 cylinder of the same bore. At 0.5 MPa it delivers 1559 N push and 1402 N pull force. A safe working load is roughly 935 N, allowing a vertical lift of about 79 kg with a 2:1 margin. The -S suffix provides a built-in magnet for CMSG, DMSG, or EMSG sensors.

Where the Airtac SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X400-100S Is Used
Variable Depth Boring
Allows operators to dial in the exact extend depth on a machining fixture by trimming up to 100 mm off the stroke.
Adjustable Diverter Arm
Sets the precise push distance for routing different package sizes on a line without changing the entire actuator.
Tiered Pallet Stops
Adjusts the stopping position on-site to accommodate varying pallet heights or load widths during packaging.
Is the Airtac SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X400-100S the Right Cylinder?
When sizing, compare both neighbors: the 50 mm bore gives 982 N push at 0.5 MPa, while the 80 mm bore yields 2513 N. This 63 mm bore hits 1559 N, making it ideal for mid-range tasks. Choose the SAUJ over a fixed SAU when your machine assembly requires field-tuning of the extend end position without buying multiple cylinders. Mounting options include Basic, FA flange, and LB foot, sharing compatibility only with the AirTAC SC series. The -S option enables electronic or reed sensing. Because the stroke is 400 mm, add external guides to prevent rod bending and manage side loads.
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 SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X400-100S FAQ
It delivers 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N at 0.9 MPa, and a max of 318 kgf at 1.0 MPa. The 400 mm nominal extend stroke can be shortened by up to 100 mm on-site using the external stop screw, giving a 300 to 400 mm usable window. It uses a 3/8 inch port and a 20 mm rod.
The -S suffix means a magnet is built into the piston for direct mounting of CMSG, DMSG, or EMSG sensors. The stop screw only sets the end position; it is not a load lock. A plain cylinder drifts on air loss, and the air cushion only decelerates near the end. For secure load holding, use an external rod lock or pilot-operated check valve.
