Airtac SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X750-100S
The AirTAC Airtac SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X750-100S is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 750mm 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 SAUJ63X750-100S
The AirTAC SAUJ63X750-100S is a double-acting single-rod profile cylinder with an external stop screw, letting you shorten the extend stroke on-site by up to 100 mm. You get a usable extend range of 650-750 mm from the 750 mm nominal maximum. The 3/8 inch port and M16x1.5 rod end handle robust pneumatic flows, while the extruded aluminum profile keeps the unit shorter than an ISO 15552 cylinder of the same 63 mm bore.
This bore delivers 1559 N push and 1402 N pull at 0.5 MPa, peaking at 2805 N push at 0.9 MPa. For sizing, the safe working load is roughly 935 N, translating to a vertical lift capacity of about 79 kg with a 2:1 safety margin. The -S suffix means a built-in magnet is present for CMSG, DMSG, or EMSG sensors. The stop screw sets the end position but does not lock the load; add an external rod lock for holding.

Where the Airtac SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X750-100S Is Used
Variable Push Assembly
Ideal for press-fit stations needing on-site extend stroke tuning within the 100 mm window to accommodate different material thicknesses without changing cylinders.
Adjustable Diverter
Perfect for conveyor sorting arms where the 650-750 mm reach must be fine-tuned at the machine to handle varying package sizes accurately.
Multi-Position Stacking
Suits palletizing tools that need to alter the final extend position by up to 100 mm on-site for different pallet heights using the external stop.
Is the Airtac SAUJ63 Adjustable Pneumatic Cylinder SAUJ63X750-100S the Right Cylinder?
When sizing this unit, look at both neighbors: the 50 mm bore gives 982 N push at 0.5 MPa, while the 80 mm bore offers 2513 N. This 63 mm model provides 1559 N, making it ideal for medium loads. Choose the SAUJ over a fixed SAU when your assembly requires field tuning of the extend stroke within that 100 mm window. Mounting options include Basic, FA flange, and LB foot, sharing compatibility only with the AirTAC SC series. The -S magnet supports CMSG/DMSG/EMSG switches. Because the 750 mm stroke is long, always use 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 SAUJ63X750-100S FAQ
At 0.5 MPa it provides 1559 N push and 1402 N pull, rising to 2182 N at 0.7 MPa and 2805 N at 0.9 MPa. The theoretical max is 318 kgf at 1.0 MPa. The 750 mm nominal extend stroke can be shortened by up to 100 mm on-site using the external stop screw, giving a 650-750 mm usable range. It uses a 3/8 inch port.
The -S suffix indicates a built-in piston magnet for mounting CMSG, DMSG, or EMSG electronic or reed sensors along the profile barrel. The adjustable stop screw only sets the extend end position; it is not a load lock. The cylinder will drift on air loss, so for load holding you must install an external rod lock or pilot-operated check valve.
