This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID32X50H, 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.
Airtac SID Series Double-Rod Cylinder SID32X50H
The AirTAC Airtac SID Series Double-Rod Cylinder SID32X50H is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 50mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID32X50H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID32X50H
The AirTAC SID32X50H is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, yielding equal force in both directions (345 N at 0.5 MPa). This SKU is discontinued; the direct replacement is the SAID32X50H, reusing the same 32 mm bore, 50 mm stroke, G1/8 port, and ISO 15552 mounting interface. The SAI upgrade features a two-piece Y-shaped piston seal for lower start-up pressure and longer life. This H-seal variant operates up to 150 C. Because it lacks the -S suffix, it cannot accept magnetic switches.
A double-rod design prevents piston rotation and lets the rear rod drive a second tool. Note that air cushions only decelerate; without live air the piston drifts, so use an external rod lock for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAID32X50H carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAID32X50H produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SID Series Double-Rod Cylinder SID32X50H Is Used
Dual-Tool Transfer
Drives two independent grippers from opposite rod ends to pick and place parts simultaneously without adding a second cylinder.
Anti-Rotation Lift
Lifts ~18 kg vertical loads using the twin rods to prevent piston twist and ensure smooth, bind-free guidance.
High-Temp Clamping
Holds workpieces in hot environments up to 150 C using the Viton H seal, providing equal clamping and release forces.
Replacing the Airtac SID Series Double-Rod Cylinder SID32X50H with the SAID32X50H
Replace the discontinued SID32X50H directly with the SAID32X50H, matching the 32 mm bore, 50 mm stroke, and G1/8 port. Force is equal both ways (345 N @0.5 MPa); if more force is needed, step up to the 40 mm bore (528 N @0.5 MPa). Choose a double-rod cylinder when you need anti-rotation stability or must drive two tools from one piston. Mounting options include Basic, FA, LB, and TC. This non-magnetic SKU cannot use sensors; add the -S suffix for switch readiness. For strokes >=300 mm, verify side-load alignment to prevent binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID32X50H
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SID Series Double-Rod Cylinder SID32X50H FAQ
Yes, the SID32X50H is discontinued. The direct replacement is the SAID32X50H, which shares the exact ISO 15552 mounting interface, 32 mm bore, 50 mm stroke, G1/8 port, and equal both-ways force.
Force is equal both ways: 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa. Operating speed is 30-800 mm/s. The G1/8 port and 27 mm adjustable cushions govern flow. Air cushions only decelerate; use an external rod lock for load holding.
