About the AirTAC SUD50
Discontinued: AirTAC has replaced the SUD series with the SAUD series. Every SUD code on this page is supplied as the current SAUD with the same code after the prefix, for example SUD50X10 ships as SAUD50X10. The specifications on this page are those of the SAUD you receive.
The AirTAC SUD50 is a double-rod, double-acting standard air cylinder with a 50 mm bore and a 20 mm piston rod. The rod runs through both end covers, so push and pull are equal: 825 N at 0.5 MPa and 1155 N at 0.7 MPa. Force depends on bore and pressure only, so every stroke on this page gives the same output.
All SUD50 versions share 1/4" air ports, an M16×1.5 rod thread and 21 mm adjustable air cushions. The cylinder runs on filtered air between 0.15 and 1.0 MPa (proof 1.5 MPa), from -20 to +70 °C, at 30 to 800 mm/s. This page lists 51 stock order codes with strokes from 10 to 500 mm; catalog standard strokes run up to 1000 mm.

Theoretical output force (Ø50 mm)
| Pressure | Push | Pull |
|---|---|---|
| 0.5 MPa | 825 N | 825 N |
| 0.7 MPa | 1155 N | 1155 N |
Both directions act on the bore area minus the Ø20 mm rod area, because the rod passes through both end covers. Usable force is lower because of friction and back-pressure.

Where the SUD50 Is Used
General automation
About 825 N at 0.5 MPa covers most pushing, lifting and indexing tasks.
Clamping fixtures
Foot or flange mounting holds the cylinder rigid for clamps.
Doors, gates and levers
Clevis and trunnion versions drive mechanisms that swing.
Choosing the Right SUD50 Configuration
Start with the stroke. Pick the exact travel your machine needs; a longer stroke adds length, weight and air consumption without adding force. If your length is not listed, request a quote and we will confirm whether it can be built.
Then choose the mounting. Basic (no code) uses the cylinder's own mounting holes. This bore is stocked with FA front flange. Foot and flange mountings hold the cylinder rigid for straight-line loads; clevis and trunnion mountings let it pivot when the load moves in an arc.
Finally pick the version: S adds a magnet for position sensors; the standard seal suits general automation; H (FKM) is for higher temperatures or oil-contaminated air; N specifies NBR.
AirTAC SUD50 FAQ
Discontinued: AirTAC has replaced the SUD series with the SAUD series. Every SUD code on this page is supplied as the current SAUD with the same code after the prefix, for example SUD50X10 ships as SAUD50X10. The specifications on this page are those of the SAUD you receive.
No. Every SUD50 gives about 825 N in both directions at 0.5 MPa, whatever the stroke.
1/4" ports, PT thread as standard.
Basic plus FA front flange. Use foot or flange for straight-line loads, clevis or trunnion when the cylinder must pivot.
Usually yes. Request a quote with the stroke, mounting and version and we will confirm whether it can be built, plus price and lead time.
0.15 to 1.0 MPa operating pressure (proof 1.5 MPa) and -20 to +70 °C on filtered air.
No. You can order a single SUD50. Orders are processed and handed to the carrier within 3-5 business days.
