This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAID100X100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAID100X100 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-SID100X100
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 100mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B04-SAID100X100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X100
The AirTAC B04-SID100X100 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, yielding equal force in both directions (3681 N at 0.5 MPa). The B04- prefix marks this as AirTAC's construction-machinery dedicated variant of the base SID100X100, mechanically identical to it. This SID model is discontinued; the exact drop-in replacement is the SAID100X100. It shares the same G1/2 port, M20x1.5 rod thread, and 3681 N equal-both-ways force.
Because both faces use the rod-side area, the second rod can drive two tools or carry a sensor cam while resisting rotation. The SAI upgrade uses a two Y-shaped one-way piston seal for low start-up pressure. Computed buyer insight: safe working load is ~2209 N (60% of the 0.5 MPa force), allowing a vertical lift of ~188 kg with a 2:1 margin. Note this non-magnetic SKU cannot take switches, and air cushions only decelerate; use SAIL or BSAI for load holding.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X100 Is Used
Excavator Linkage Actuation
Drives dual-tool mechanisms on heavy equipment with equal push and pull force, leveraging the rigid ISO 15552 interface to withstand construction-site shocks.
Crane Extension Guidance
Uses the double-rod geometry to prevent rotation during linear extension, ensuring precise alignment of structural components without twist.
Loader Attachment Sync
Simultaneously operates two opposing attachment points from one piston, relying on the 3681 N equal both-ways force for balanced load handling.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X100 with the B04-SAID100X100
To replace the discontinued B04-SID100X100, specify the SAID100X100 drop-in: it matches the ISO 15552 interface, 100 mm bore, 100 mm stroke, G1/2 port, and 3681 N equal-both-ways force. Size both ways by checking neighbor bores (80 mm yields 2268 N, 125 mm yields 5734 N at 0.5 MPa) to ensure the equal pull/push fits your load. A double rod is right when you need anti-rotation or dual-tool driving. Reuse FA, LB, or TC mounts. This SKU lacks the -S magnet, so it cannot accept sensors. For stroke >=300 mm, verify side-load bearing limits.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID100X100
- ✓ 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-SID100X100 FAQ
Yes, the B04-SID100X100 (construction-machinery dedicated variant) is discontinued. The exact drop-in replacement is the SAID100X100. It shares the identical ISO 15552 mounting interface, 100 mm bore, 100 mm stroke, G1/2 port, and equal both-ways force. The SAI family also adds upgraded seals and lock variants like SAIL and BSAI.
Force is equal both ways: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. It never quotes a larger single-rod push value. The bore uses a G1/2 air port, an M20x1.5 rod thread, and adjustable 36 mm cushions. Safe working load is ~2209 N, allowing a ~188 kg vertical lift.
