Airtac SAUD Double Rod Cylinder SAUD50X850
The AirTAC Airtac SAUD Double Rod Cylinder SAUD50X850 is a genuine double-acting profile-type standard air cylinder with a Ø50mm bore and 850mm 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 SAUD50X850
The AirTAC SAUD50X850 is a double-acting, double-rod profile cylinder with a 50 mm bore and an 850 mm stroke. A piston rod protrudes from both end caps, meaning both faces use the identical rod-side area. Consequently, the output force is perfectly balanced at 825 N each way at 0.5 MPa. The extruded aluminium barrel keeps the overall body shorter than a standard ISO 15552 unit of the same bore.
Because this SKU lacks the -S suffix, it cannot accept magnetic position switches. For sizing context, the 825 N output yields a safe working load of roughly 495 N, which translates to a vertical lift capacity of about 42 kg with a 2:1 safety margin. You can pair it with AirTAC SC-series FA flange or LB foot mounts, and a Viton H seal upgrade extends operation to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD50X850 Is Used
Twin-Tool Stamping
Drives two synchronized forming punches from opposite rod ends to press small metal clips simultaneously.
Dual-End Diverting
Pushes a diverting blade from either side of a packaging line to reroute cartons without rotating the assembly.
Balanced Lowering Lift
Lowers a 42 kg fixture evenly using both rod ends to prevent twist on a long 850 mm vertical descent.
Is the Airtac SAUD Double Rod Cylinder SAUD50X850 the Right Cylinder?
When sizing this unit, consider the adjacent bores: the 40 mm version provides 528 N each way, while the 63 mm offers 1402 N. Choose this 50 mm double-rod model when your mechanism requires strict anti-rotation guidance, needs to drive two tools simultaneously, or uses the back rod to trip a mechanical switch. The 1/4" port matches the 50 mm bore specification. With an 850 mm stroke, you must use external guide rails to prevent rod bending and absorb side loads. This plain cylinder cannot hold a load without live air; the cushions only decelerate, so fit an external rod lock for vertical safety.
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 SAUD50X850 FAQ
The force is equal in both directions because the double-rod design uses the rod-side area on both faces. It generates 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa. The unit features a 1/4" port and adjustable cushions at both ends.
No, this specific SKU does not include the -S magnet option, so it cannot host CMSG, DMSG, or EMSG reed switches. You would need to specify a -S model for position sensing, or use the protruding back rod to trigger an external mechanical limit switch.
