This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement B04-SAID32X200S, 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-SID32X200S
The AirTAC B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID32X200S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 200mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the B04-SAID32X200S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID32X200S
The AirTAC B04-SID32X200S is a double-acting, double-rod ISO 15552 cylinder where the B04- prefix marks it as a construction-machinery dedicated variant, mechanically identical to the standard SID32X200S. Because a rod exits both ends, both faces use the rod-side area, making push and pull force equal at 345 N @0.5 MPa. The bore is 32 mm, the port is G1/8, and it has a 12 mm rod with M10x1.25 threads. This legacy model is discontinued; the direct replacement is SAID32X200S, which reuses the exact ISO 15552 mounting interface.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. A double-rod design prevents rotation and lets the back rod carry a sensor cam. Note that air cushions only decelerate; for load holding without live air, use an external rod lock or SAIL variant.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID32X200S Is Used
Excavator Linkage Actuation
Drives dual-tool mechanisms on construction machinery where equal push and pull force is required to pivot heavy equipment linkages without rotational deflection.
Crusher Feed Control
Regulates material flow on heavy equipment by moving a gate from both ends, ensuring stable positive positioning in dusty construction environments.
Dual-Tool Synchronized Drive
Powers two separate work tools simultaneously from one piston, using the extending front rod and rear rod to perform mirrored operations on a machinery frame.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID32X200S with the B04-SAID32X200S
To replace the B04-SID32X200S, use the SAID32X200S. It is a direct upgrade keeping the 32 mm bore, 200 mm stroke, G1/8 port, and ISO 15552 mounting dimensions. When sizing both ways, verify the 345 N @0.5 MPa equal force fits your load, or step to the 40 mm bore for 528 N. Choose a double-rod cylinder when you need anti-rotation stability or must drive two tools simultaneously. Reuse FA, LB, or TC mounts. The -S suffix means a magnet is present for CS1-B/DS1-B sensors. For strokes >=300 mm, verify side-load bearing limits.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID32X200S
- ✓ 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-SID32X200S FAQ
Yes, the B04-SID32X200S is discontinued. The direct replacement is the SAID32X200S. The B04- prefix simply denotes the construction-machinery dedicated variant; mechanically it is identical to the SID32X200S. The SAID replacement shares the same 32 mm bore, 200 mm stroke, G1/8 port, and ISO 15552 mounting interface.
Force is equal both ways because it is a double-rod cylinder: 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. The operating speed is 30-800 mm/s. It uses a G1/8 port and has adjustable air cushions of 27 mm at each end. Air cushions only decelerate; they do not hold loads on air loss.
