This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAID32X200 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAID32X200 in place of this model. 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-SID32X200
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID32X200 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 drop-in replacement is the B04-SAID32X200, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID32X200
The AirTAC B04-SID32X200 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, ensuring push and pull force are equal (345 N at 0.5 MPa). The B04- prefix marks this as a construction-machinery dedicated variant, mechanically identical to the standard SID32X200 with a 32 mm bore, 200 mm stroke, M10x1.25 rod thread, and G1/8 port. This legacy SID model is discontinued; the exact drop-in replacement is the SAID32X200, which reuses the same ISO 15552 mounting interface and adds an upgraded piston seal using two Y-shaped one-way elements for lower start-up pressure and longer life.
Because both faces use the rod-side area, force is identical in both directions. This layout prevents rod rotation and allows the back rod to drive a second tool or sensor cam. Based on the 345 N output at 0.5 MPa, the safe working load is roughly 207 N, translating to a vertical lift capacity of about 18 kg with a 2:1 margin. Note that this SKU lacks a magnet (-S) and cannot accept magnetic switches. A plain cylinder will not hold a load on air loss; the 27 mm adjustable cushions only decelerate near stroke end, so use an external rod lock or SAIL variant for held loads.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID32X200 Is Used
Excavator Linkage
Equal push/pull force actuates secondary construction-machinery covers or locks without rod rotation, fitting heavy-equipment space constraints.
Synchronized Pusher
The rear rod drives a secondary mechanism or cam simultaneously on heavy-equipment assembly lines, doubling actuation points from one cylinder.
Lift Gate Counter
Provides stable vertical load handling in construction vehicle lift mechanisms where equal force both ways prevents sagging drift.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID32X200 with the B04-SAID32X200
To replace the discontinued B04-SID32X200, specify the SAID32X200 drop-in: it matches the 32 mm bore, 200 mm stroke, G1/8 port, and ISO 15552 mounting dimensions (Basic, FA, LB, TC) exactly. Size both directions by the equal-both-ways force; if 345 N at 0.5 MPa is insufficient, step up to the 40 mm bore (528 N). Choose a double-rod cylinder when you need anti-rotation stability or synchronized two-end actuation. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear. This non-magnetic SKU cannot use sensors; if detection is needed, select an -S magnet model and CS1-B/DS1-B switches.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID32X200
- ✓ 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-SID32X200 FAQ
Yes, the B04-SID32X200 is discontinued. The exact drop-in replacement is the SAID32X200. The B04- prefix simply marks it as construction-machinery dedicated; mechanically it is identical to the base SID32X200. The SAID replacement shares the same 32 mm bore, 200 mm stroke, G1/8 port, and ISO 15552 mounting interface, but features an upgraded piston seal.
Because it is a double-rod cylinder, force is equal both ways: 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa. The air port is G1/8. The safe working load is approximately 207 N. Remember that cushions only decelerate; use an external rod lock for load holding.
