This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID100X100TC, 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 SID100X100TC
The AirTAC Airtac SID Series Double-Rod Cylinder SID100X100TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 100mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID100X100TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID100X100TC
The AirTAC SID100X100TC is a discontinued ISO 15552 double-acting double-rod cylinder. A rod exits both ends on one piston, meaning both faces use the rod-side area and push/pull force is equal at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The direct replacement is the SAID100X100TC, matching the 100mm bore, 100mm stroke, G1/2 port, and TC mounting interface.
The SAI upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. Double-rod benefits include anti-rotation and driving two tools. This non-magnetic SKU cannot take a switch. A plain cylinder drifts on air loss; cushions only decelerate, so use an external rod lock for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAID100X100TC carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAID100X100TC 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 SID100X100TC Is Used
Synchronized Transfer Pusher
Drives two parallel conveyor lanes simultaneously using both rod ends, ensuring perfectly timed material transfer without torsional twist.
Anti-Rotation Workpiece Clamp
The dual-rod geometry resists rotational torque during heavy clamping, maintaining precise alignment of the 100mm bore actuator under offset loads.
Dual-Action Lift Station
Lifts a 188kg vertical payload using the back rod as a counter-mass cam while the front rod elevates the platform, exploiting equal both-ways force.
Replacing the Airtac SID Series Double-Rod Cylinder SID100X100TC with the SAID100X100TC
Replace the discontinued SID100X100TC directly with the SAID100X100TC, reusing the existing ISO 15552 TC mounting and G1/2 port. Size both ways by checking neighbor bores: the 80mm bore yields 2268 N @0.5 MPa, while the 125mm bore yields 5734 N @0.5 MPa, but this 100mm bore provides 3681 N @0.5 MPa equally in both directions. Choose a double-rod cylinder when you need anti-rotation or must drive two tools simultaneously. This SKU lacks the -S magnet and cannot accept a sensor. For stroke lengths of 300mm or more, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID100X100TC
- ✓ 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 SID100X100TC FAQ
Yes, the SID100X100TC is discontinued. The direct replacement is the SAID100X100TC. It shares the same ISO 15552 interface, 100mm bore, 100mm stroke, G1/2 port, and TC mounting, plus an upgraded two Y-shaped one-way piston seal for longer life.
Because it is a double-rod cylinder, force is equal both ways at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The bore is 100mm, the air port is G1/2, the rod thread is M20x1.5, and it has 36mm adjustable air cushions at each end.
