This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement B04-SAID32X80S, 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-SID32X80S
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID32X80S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 80mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the B04-SAID32X80S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID32X80S
The AirTAC B04-SID32X80S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston, making push and pull force equal both ways (345 N @0.5 MPa). The B04- prefix marks this as a construction-machinery dedicated variant of the base SID32X80S; it is mechanically identical, retaining the 32 mm bore, 80 mm stroke, G1/8 port, and M10x1.25 rod thread. This SID model is discontinued and the direct replacement is the SAID32X80S.
Because both faces use the rod-side area, force is equal both ways, which prevents rod deflection and allows the back rod to carry a sensor cam for CS1-B/DS1-B switches. The SAID upgrade adds a two Y-shaped one-way piston seal for low start-up pressure.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID32X80S Is Used
Excavator Linkage
Equal-both-ways force drives dual-tool mechanisms on construction machinery without rod deflection.
Material Transfer
Pushes and pulls a heavy-equipment conveyor diverter with identical force and anti-rotation stability.
Guide Alignment
Uses the back rod to carry a sensor cam for precise positioning of construction-machine panels.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID32X80S with the B04-SAID32X80S
To replace the discontinued B04-SID32X80S, specify SAID32X80S; it shares the exact ISO 15552 mounting interface, bore, stroke, and G1/8 port. Size both ways by checking neighbor bores if you need more equal-both-ways force. A double rod is right when you need anti-rotation or must drive two tools. Reuse FA, LB, or TC mounts. The -S magnet enables legacy CS1-B/DS1-B switches. For stroke >=300, verify side-load limits. A plain cylinder does not hold loads on air loss; use an external rod lock or SAIL/BSAI variant.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID32X80S
- ✓ 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-SID32X80S FAQ
Yes, the B04-SID32X80S is discontinued. The direct replacement is the SAID32X80S. The B04- prefix only marks the construction-machinery dedicated variant; mechanically it is identical to SID32X80S. The SAID keeps the same ISO 15552 interface, 32 mm bore, 80 mm stroke, and G1/8 port.
Force is equal both ways at 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. Speed is 30-800 mm/s. The adjustable air cushion is 27 mm at each end. It operates at 0.15-1.0 MPa.
