This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID32X125, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.

The AirTAC Airtac SID Series Double-Rod Cylinder SID32X125 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 125mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID32X125, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SID32X125 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, yielding equal push and pull force (345 N @0.5 MPa). Because both faces use the rod-side area, it resists rotation and can drive two tools. This discontinued model drops directly into the SAID32X125, sharing the G1/8 port, M10x1.25 thread, and 27 mm cushion.
The SAID32X125 successor retains the exact ISO 15552 mounting interface and introduces an upgraded two-piece Y-shaped piston seal for lower start-up pressure. Without a -S suffix, this SKU lacks a magnet and cannot carry a sensor.

The SAID32X125 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Legacy SI-family variants: SID (double rod), SIJ (adjustable stroke) — each maps to its SAI equivalent (SID→SAID, SIJ→SAIJ). Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B).
Drives two opposing grippers to center and transfer thin workpieces simultaneously, using equal both-ways force to maintain balanced handling.
Moves a small machining fixture without rotational drift, relying on the dual rods to prevent yaw during rapid 30-800 mm/s positioning.
Powers a push assembly on the front face while the rear rod trips a mechanical cam, coordinating two machine actions in one stroke.
Replace the discontinued SID32X125 with the direct replacement SAID32X125, reusing your existing FA, LB, or TC mounts. Size both directions by equal force: if 345 N @0.5 MPa is insufficient, step up to the 40 mm bore (528 N) or down to a smaller bore. Choose a double-rod cylinder when you need anti-rotation stability or a back rod to carry a sensor cam. This non-magnetic SKU cannot take a switch; add the -S suffix on the SAID for legacy CS1-B/DS1-B sensor accuracy. For this 125 mm stroke, side-load is minimal, but for strokes >=300 mm ensure guide alignment to prevent binding.
Replacement checklist
Yes, the SID32X125 is discontinued. The direct replacement is the SAID32X125, which shares the same ISO 15552 interface, 32 mm bore, 125 mm stroke, G1/8 port, and equal both-ways force.
Force is equal both ways: 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. It operates at 0.15-1.0 MPa, runs at 30-800 mm/s, and uses a G1/8 port with M10x1.25 rod threads. The air cushion only decelerates; use an external rod lock for load holding.
Send us the quantity and destination. We confirm price, stock and lead time on the SAID32X125 replacement — usually within 7-8 hours.
