This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID32X100S, 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 SID32X100S
The AirTAC Airtac SID Series Double-Rod Cylinder SID32X100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 100mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID32X100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID32X100S
The AirTAC SID32X100S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston. Because both faces use the rod-side area, push and pull force are equal at 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. This model is discontinued and drops-in directly to the SAID32X100S, matching the 32 mm bore, 100 mm stroke, G1/8 port, and M10x1.25 rod thread. The SAI replacement upgrades the piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life.
A second rod provides anti-rotation stability and can carry a sensor cam or drive a second tool simultaneously. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches. Note that air cushions only decelerate near stroke end; a plain cylinder drifts on air loss, so use an external rod lock or SAIL/BSAI variant for held loads.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |

Where the Airtac SID Series Double-Rod Cylinder SID32X100S Is Used
Synchronized Tool Driving
Drives two separate tooling operations from one piston, utilizing the equal push and pull force of 345 N @0.5 MPa on both rod ends for balanced machinery actuation.
Anti-Rotation Guiding
Ideal for precise gripping tasks where the dual 12 mm rods exiting both ends prevent mechanical twist, maintaining strict alignment without external guide rails.
Dual-End Sensor Camming
Uses the back rod to carry a sensor cam for legacy CS1-B/DS1-B switches, allowing compact placement of position feedback in tight 32 mm bore automation cells.
Replacing the Airtac SID Series Double-Rod Cylinder SID32X100S with the SAID32X100S
To replace the discontinued SID32X100S, install the direct replacement SAID32X100S, reusing the existing ISO 15552 mounting interface (Basic, FA, LB, or TC) without modifications. Size both ways by verifying the equal push/pull force of 483 N @0.7 MPa is sufficient; if more force is needed, step up to the 40 mm bore (739 N @0.7 MPa) which uses a G1/4 port. A double-rod design is right when you need strict anti-rotation or symmetrical tool driving. The -S magnet enables position sensing. For strokes >=300 mm, verify side-load limits to prevent premature seal wear. Operating speed is 30-800 mm/s.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID32X100S
- ✓ 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 SID32X100S FAQ
Yes, the AirTAC SID32X100S is discontinued. The direct replacement is the SAID32X100S. It shares the same ISO 15552 interface, 32 mm bore, 100 mm stroke, G1/8 port, and equal both-ways force, but features an upgraded two-piece Y-shaped piston seal.
Because it is a double-rod cylinder, force is equal both ways: 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. The fixed air port is G1/8, the rod thread is M10x1.25, and it features 27 mm adjustable air cushions at each end.
