This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement B04-SAID100X80, 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 B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X80
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X80 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 80mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the B04-SAID100X80, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X80
The AirTAC B04-SID100X80 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, ensuring force is equal both ways (3681 N at 0.5 MPa). The B04- prefix marks this as AirTAC's construction-machinery dedicated variant of the base SID100X80, mechanically identical to the standard model. This discontinued SKU is fully replaced by the SAID100X80, offering the same G1/2 port, M20x1.5 rod thread, and 3681 N equal push/pull force.
Because both faces use the rod-side piston area, the cylinder provides anti-rotation stability and can drive two tools simultaneously. The SAI upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note this non-magnetic SKU cannot take a sensor, and the air cushion only decelerates; use an external rod lock for held loads.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X80 Is Used
Excavator Boom Control
Drives dual opposing tools on heavy-equipment frames with equal 3681 N push and pull force, preventing rotational drift during hydraulic-assisted movements.
Loader Linkage Actuation
Provides stable bidirectional clamping on construction-machinery arms, utilizing the G1/2 port and 80 mm stroke for rapid, balanced material handling.
Crusher Plant Diverter
Handles rugged aggregate routing with equal-both-ways force and ISO 15552 mounting durability, fitting seamlessly into existing heavy-equipment footprints.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X80 with the B04-SAID100X80
To replace the discontinued B04-SID100X80, specify the direct replacement SAID100X80, which reuses the exact ISO 15552 mounting interface (Basic, FA, LB, TC) and G1/2 port. Size both ways by checking neighbouring bores: the 80 mm bore yields 2268 N, while the 125 mm bore yields 5734 N at 0.5 MPa, ensuring you match the required equal-both-ways force. Choose a double-rod cylinder when anti-rotation or driving two tools is required. As this SKU lacks the -S magnet, it cannot accept magnetic switches. For stroke lengths >=300, verify side-load bearing limits. Note that air cushions only decelerate; for load holding without live air, use the SAIL or BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID100X80
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X80 FAQ
Yes, the B04-SID100X80 (construction-machinery dedicated SID100X80) is discontinued. The direct replacement is the SAID100X80, sharing the same ISO 15552 interface, 100 mm bore, 80 mm stroke, G1/2 port, and equal-both-ways force.
Force is equal both ways: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. The air port is G1/2.
