This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement B04-SAID63X600S, 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-SID63X600S
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID63X600S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 600mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the B04-SAID63X600S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID63X600S
The B04-SID63X600S is a double-acting, double-rod ISO 15552 cylinder where the B04- prefix designates it as the construction-machinery dedicated variant of the base SID63X600S, mechanically identical with a 63mm bore, 600mm stroke, and G3/8 port. Because a rod exits both ends on one piston, both faces use the rod-side area, making push and pull force equal at 1402 N @0.5 MPa. This model is discontinued and the direct replacement is the SAID63X600S, which retains the same ISO 15552 mounting interface, bore, stroke, and force.
The double-rod design provides inherent anti-rotation properties and allows the rear rod to carry a sensor cam, driving two tools simultaneously. The SAI replacement upgrades to a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note that air cushions only decelerate near stroke end; for load holding without live air, use an external rod lock or the SAIL/BSAI lock variant.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID63X600S Is Used
Excavator Linkage Actuation
Drives synchronized dual-tool mechanisms on heavy equipment where equal push and pull force is mandatory for balanced machinery linkage movement.
Crane Slew Positioning
Provides anti-rotation stability for precise positioning of construction components, utilizing the rear rod to mount a sensor cam for feedback.
Heavy-Duty Material Handling
Shifts structural loads in construction machinery fixtures, relying on the 63mm bore and G3/8 port to deliver consistent both-ways force.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID63X600S with the B04-SAID63X600S
To replace the discontinued B04-SID63X600S, specify the SAID63X600S direct, keeping the ISO 15552 mounting interface (Basic, FA, LB, TC) and the built-in -S magnet for CS1-B/DS1-B switches. Size both ways by checking neighbor bores while relying on the equal both-ways force of 1402 N @0.5 MPa. Choose a double-rod configuration when you need anti-rotation, dual-tool driving, or a back-rod sensor cam. For this 600 mm stroke, external guides are recommended to prevent rod bending under side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID63X600S
- ✓ 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-SID63X600S FAQ
Yes, the B04-SID63X600S is discontinued. The direct replacement is the SAID63X600S. The B04- prefix simply marks it as the construction-machinery dedicated variant of the base SID63X600S, so the SAID replacement shares the exact same 63mm bore, 600mm stroke, G3/8 port, and ISO 15552 mounting interface.
Because it is a double-rod cylinder, force is equal both ways: 1402 N @0.5 MPa, 1962 N @0.7 MPa, and 2523 N @0.9 MPa. The air port is G3/8, the rod thread is M16x1.5, and the adjustable air cushion is 30 mm at each end.
