About the AirTAC SGD250
The AirTAC SGD250 is a double-rod, double-acting steel-barrel large-bore ISO 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 SGD250 versions share 1" air ports, an M42×2.0 rod thread and 60 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 22 stock order codes with strokes from 25 to 1000 mm; the catalog maximum stroke is 1000 mm.

Theoretical output force (Ø250 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.
How the SGD250 Order Code Is Built
| SGD250 | Series and bore (250 mm) |
|---|---|
| X100 | Stroke in mm |
| LB / FA / TC / FTC | Mounting: LB foot; FA front flange; TC center trunnion; FTC front trunnion (blank = none) |
| H | Seal: H = FKM (blank = NBR) |
| G | Port thread: G = G (BSPP), blank = PT |

Where the SGD250 Is Used
High-force actuation
Over 23.6 kN at 0.5 MPa for presses, lifting tables and dampers.
Process and material handling
Opens chutes, gates and dampers on bulk-handling equipment.
Pivoting heavy loads
Clevis and trunnion versions swing large doors and platforms.
Choosing the Right SGD250 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. 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: the steel barrel takes no sensor magnet; H (FKM) is for higher temperatures or oil-contaminated air.
AirTAC SGD250 FAQ
No. Every SGD250 gives about 23562 N in both directions at 0.5 MPa, whatever the stroke.
1" ports, PT thread as standard.
Basic mounting only. Pick a pivoting cover or bracket when the load moves in an arc, a rigid one for straight-line loads.
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 SGD250. Orders are processed and handed to the carrier within 3-5 business days.
