About the AirTAC SAI50
The AirTAC SAI50 is a double-acting ISO 15552 profile-barrel cylinder with a 50 mm bore and a 20 mm piston rod. At 0.5 MPa it pushes 982 N and pulls 825 N; at 0.7 MPa that rises to 1374 N push and 1155 N pull. Force depends on bore and pressure only, so every stroke on this page gives the same output.
All SAI50 versions share 1/4" air ports, an M16×1.5 rod thread and 30 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 161 stock order codes with strokes from 5 to 1700 mm; catalog standard strokes run up to 1200 mm, and the longer codes are non-standard strokes we already supply.

Theoretical output force (Ø50 mm)
| Pressure | Push | Pull |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | 1155 N |
Push = pressure × bore area; pull subtracts the Ø20 mm rod area. Usable force is lower because of friction and back-pressure.
How the SAI50 Order Code Is Built
| SAI50 | Series and bore (50 mm) |
|---|---|
| X100 | Stroke in mm |
| S | Built-in magnet for position sensors (blank = none) |
| FA / CA / TC / FTC | Mounting: FA front flange, CA single clevis, TC center trunnion, FTC front trunnion |
| H / N | Seal: H = FKM, N = NBR (blank = standard seal) |
| G | Port thread: G = G (BSPP), blank = PT |

Where the SAI50 Is Used
General automation
About 982 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 SAI50 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, CA single clevis, TC center trunnion, FTC front 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; N specifies NBR; G replaces the standard PT ports with G (BSPP).
AirTAC SAI50 FAQ
No. Every SAI50 gives about 982 N push and 825 N pull at 0.5 MPa, whatever the stroke.
1/4" ports, PT thread as standard. The G version has G (BSPP) ports.
Basic plus FA front flange, CA single clevis, TC center trunnion, FTC front 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.
No. You can order a single SAI50. Orders are processed and handed to the carrier within 3-5 business days.
