The AirTAC SCD250 is a double-rod, double-acting tie-rod cylinder with a 250 mm bore and a 50 mm piston rod. The rod runs through both end covers, so push and pull are equal: 23562 N at 0.5 MPa and 32987 N at 0.7 MPa. Force depends on bore and pressure only, so every stroke on this page gives the same output.
All SCD250 versions share 1" air ports, an M42×2 rod thread and 40 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 500 mm/s. This page lists 34 stock order codes with strokes from 25 to 900 mm; catalog standard strokes run up to 1000 mm.

| Pressure | Push | Pull |
|---|---|---|
| 0.5 MPa | 23562 N | 23562 N |
| 0.7 MPa | 32987 N | 32987 N |
Both directions act on the bore area minus the Ø50 mm rod area, because the rod passes through both end covers. Usable force is lower because of friction and back-pressure.

Over 23.6 kN at 0.5 MPa for presses, lifting tables and dampers.
Opens chutes, gates and dampers on bulk-handling equipment.
Clevis and trunnion versions swing large doors and platforms.
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.
Every code on this page is the basic version without a mounting code: the cylinder is fixed through its own mounting holes.
Finally pick the version: S adds a magnet for position sensors; the standard seal suits general automation.
No. Every SCD250 gives about 23562 N in both directions at 0.5 MPa, whatever the stroke.
1" ports, PT thread as standard.
Every code on this page is the basic version without a mounting code; the cylinder is fixed through its own mounting holes.
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.
