Airtac SAUD Double Rod Cylinder SAUD50X500
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X500 is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 500mm stroke, 1/4" 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 SAUD Double Rod Cylinder SAUD50X500
The AirTAC SAUD50X500 is a double-acting, double-rod profile cylinder with a 50 mm bore and 500 mm stroke. A rod protrudes from both ends, meaning both faces use the rod-side piston area. This yields equal output force in both directions, rated at 825 N each way at 0.5 MPa. The extruded aluminium profile barrel keeps the unit shorter than an ISO 15552 cylinder of the same bore.
This SKU has no internal magnet, so it cannot accept CMSG, DMSG, or EMSG magnetic switches. The 1/4" port and M16x1.5 rod thread are fixed by the bore. For sizing, the safe working load is roughly 495 N, and it can vertically lift about 42 kg with a 2:1 safety margin. A Viton H seal option raises the operating ceiling to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD50X500 Is Used
Twin-Tool Transfer
Drives two parallel pickers simultaneously from one piston, keeping stroke synchronized without adding a second actuator.
Balanced Vertical Lift
Lifts and lowers a 42 kg platen with equal force both ways, preventing gravity-induced drift during downward travel.
Anti-Rotation Clamp
Holds a workpiece flat using the dual rods to resist twist, ensuring the clamp face never skews under offset loads.
Is the Airtac SAUD Double Rod Cylinder SAUD50X500 the Right Cylinder?
When sizing this 50 mm bore (825 N both ways at 0.5 MPa), step down to the 40 mm bore for 528 N, or up to the 63 mm bore for 1402 N. Choose this double-rod configuration when you need anti-rotation guidance, twin tooling, or a back rod to trip a switch. Mounting is limited to Basic, FA, and LB styles, matching the AirTAC SC series. Because the stroke is 500 mm, add external guide rails to prevent rod bending under side loads. Note that this non-magnetic SKU cannot host sensors.
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 SAUD Double Rod Cylinder SAUD50X500 FAQ
Force is equal in both directions because both faces carry a rod. It delivers 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa. The 1/4" port supplies air for these figures.
No. A plain cylinder drifts on air loss; the adjustable 21 mm cushions only decelerate near stroke end. For load holding, install an external rod lock or pilot-operated check valve.
