About the AirTAC SID125
Discontinued: AirTAC has replaced the SID series with the SAID series. Every SID code on this page is supplied as the current SAID with the same code after the prefix, for example SID125X10 ships as SAID125X10. The specifications on this page are those of the SAID you receive.
The AirTAC SID125 is a double-rod, double-acting ISO 15552 profile-barrel cylinder with a 125 mm bore and a 32 mm piston rod. The rod runs through both end covers, so push and pull are equal: 5734 N at 0.5 MPa and 8027 N at 0.7 MPa. Force depends on bore and pressure only, so every stroke on this page gives the same output.
All SID125 versions share 1/2" air ports, an M27×2 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 63 stock order codes with strokes from 10 to 1000 mm; catalog standard strokes run up to 1000 mm.

Theoretical output force (Ø125 mm)
| Pressure | Push | Pull |
|---|---|---|
| 0.5 MPa | 5734 N | 5734 N |
| 0.7 MPa | 8027 N | 8027 N |
Both directions act on the bore area minus the Ø32 mm rod area, because the rod passes through both end covers. Usable force is lower because of friction and back-pressure.
How the SID125 Order Code Is Built

Where the SID125 Is Used
High-force actuation
Over 5.7 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 SID125 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 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.
AirTAC SID125 FAQ
Discontinued: AirTAC has replaced the SID series with the SAID series. Every SID code on this page is supplied as the current SAID with the same code after the prefix, for example SID125X10 ships as SAID125X10. The specifications on this page are those of the SAID you receive.
No. Every SID125 gives about 5734 N in both directions at 0.5 MPa, whatever the stroke.
1/2" ports, PT thread as standard.
Basic plus TC center trunnion. Use foot or flange for straight-line loads, clevis or trunnion when the cylinder must pivot.
The standard rod is medium carbon steel. The ordering code also allows A (SUS420J2) and B (SUS304) stainless rods; request a quote for those versions.
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 SID125. Orders are processed and handed to the carrier within 3-5 business days.
