The AirTAC SCD50 is a double-rod, double-acting tie-rod 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 SCD50 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 74 stock order codes with strokes from 5 to 1405 mm; catalog standard strokes run up to 1000 mm, and the longer codes are non-standard strokes we already supply.

| 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.

About 825 N at 0.5 MPa covers most pushing, lifting and indexing tasks.
Foot or flange mounting holds the cylinder rigid for clamps.
Clevis and trunnion versions drive mechanisms that swing.
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 LB foot, FA front flange, TC center trunnion. 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.
No. Every SCD50 gives about 825 N in both directions at 0.5 MPa, whatever the stroke.
1/4" ports, PT thread as standard.
Basic plus LB foot, FA front flange, TC center trunnion. 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.
