This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID100X200, 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 SID100X200 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 200mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID100X200, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SID100X200 is a double-acting double-rod ISO 15552 cylinder where a rod exits both ends, making the push and pull force equal at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. This SKU is discontinued and the direct replacement is the SAID100X200, retaining the 100mm bore, 200mm stroke, G1/2 port, and adjustable 36mm cushions. The SAI family uses an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
Because both faces use the rod-side area, the equal both ways force prevents rod drift and allows the back rod to drive a second tool. This non-magnetic SKU cannot take a switch. A plain cylinder does not hold loads on air loss; the cushion only decelerates. For held loads use an external rod lock or SAIL/BSAI variant.

The SAID100X200 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 tools simultaneously from a single piston, utilizing the equal both ways force to ensure perfectly synchronized cutting or clamping operations.
The dual exiting rods prevent mechanical rotation during high-speed part transfer across a conveyor belt, maintaining precise alignment without external guides.
Lifts and lowers a heavy access gate with equal push and pull force, ensuring smooth descent and ascent without requiring differential pressure compensation.
Replace the discontinued SID100X200 directly with the SAID100X200, reusing the exact ISO 15552 mounting interface and FA, LB, or TC brackets. Size both ways by checking neighbouring bores if you need more or less equal force. Choose a double rod when you need anti-rotation stability or a back rod to mount a sensor cam. This non-magnetic SKU cannot take a switch. For stroke lengths of 300mm or longer, verify side-load limits to prevent guide wear.
Replacement checklist
Yes, the SID100X200 is discontinued. The direct replacement is the SAID100X200, which matches the 100mm bore, 200mm stroke, G1/2 port, and ISO 15552 mounting. The SAI family also adds an upgraded piston seal and SAIL or BSAI lock variants the SI line lacked.
Force is equal both ways: 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The air port is G1/2, the rod is Ø25mm with an M20x1.5 thread, and it features a 36mm adjustable cushion at each end. Speed is 30-800 mm/s.
Send us the quantity and destination. We confirm price, stock and lead time on the SAID100X200 replacement — usually within 7-8 hours.
