This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID100X160S, 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 SID100X160S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 160mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID100X160S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SID100X160S is a discontinued ISO 15552 double-rod, double-acting cylinder where a rod exits both ends on one piston. Both faces use the rod-side area, yielding equal push and pull force of 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. It features a 100mm bore, 25mm rod, M20x1.5 thread, 36mm adjustable cushions, a G1/2 port, and a built-in magnet for legacy CS1-B/DS1-B switches. The direct replacement is the SAID100X160S, matching the stroke, force, and mounting interface.
This double-rod design prevents rotation and lets the back rod drive a second tool or carry a sensor cam. The SAI upgrade adds a two-piece Y-shaped piston seal for lower start-up pressure and longer life. 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.

The SAID100X160S 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 machining heads simultaneously using both extending rods, ensuring perfectly synchronized cutting cycles without adding a second cylinder.
Moves a diverting gate across a conveyor line with high lateral stability, using the double-rod construction to prevent the mechanism from twisting under off-center loads.
Pushes and pulls a stacking fixture with equal 3681 N force at 0.5 MPa, allowing the arm to lift a pallet layer on the push stroke and retract a fixture on the pull stroke.
To replace the discontinued SID100X160S, install the direct replacement SAID100X160S, which preserves the ISO 15552 mounting interface, 160mm stroke, G1/2 port, and equal both-ways force. Because both directions use the rod-side area, size the replacement by matching this equal force; if more capacity is needed, step up to the 125mm bore, or drop to the 80mm bore if lower force suffices. A double-rod cylinder is the right choice when you need anti-rotation stability or want to drive two tools from one piston. Reuse your FA, LB, or TC mounts, and keep the -S magnet option for switch sensing. For this 160mm stroke, side-load is minimal, but for any stroke over 300mm, ensure guide rails to prevent rod binding.
Replacement checklist
Yes, the SID100X160S is discontinued. The direct replacement is the SAID100X160S. It shares the same ISO 15552 mounting interface, 100mm bore, 160mm stroke, G1/2 port, and equal both-ways force. The SAI family also upgrades the piston seal to a two-piece Y-shaped element for lower start-up pressure and longer life.
Force is equal both ways (push and pull) because both piston faces use the rod-side area: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. Operating speed is 30-800 mm/s.
