This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAID100X500 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAID100X500 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-SID100X500
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X500 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 500mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B04-SAID100X500, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X500
The AirTAC B04-SID100X500 is a double-acting, double-rod ISO 15552 cylinder where the B04- prefix designates it as a construction-machinery dedicated variant of the base SID100X500, mechanically identical to it. A rod exits both ends on a single piston, meaning both faces use the rod-side area and push/pull force is equal both ways at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. It features a 100mm bore, G1/2 port, M20x1.5 rod thread, and 36mm adjustable cushions. This SID model is discontinued and end-of-life.
The exact drop-in replacement is the SAID100X500, sharing the same ISO 15552 interface, bore, stroke, and mounting. The SAI upgrade uses an upgraded piston seal (two Y-shaped one-way elements for low start-up pressure and long life) and adds SAIL/BSAI lock variants. For sizing, the equal-both-ways force yields a safe working load of 2209 N (60% of the 3681 N @0.5 MPa figure) and a vertical lift capacity of 188 kg with a 2:1 margin. Note this SKU lacks a -S magnet, so it cannot take a magnetic switch. A plain cylinder does not hold loads on air loss; use an external rod lock for held loads.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X500 Is Used
Excavator Linkage Control
Drives dual-tool mechanisms on heavy equipment with equal push and pull force, preventing linkage binding under harsh construction-machinery cycles.
Aggregate Gate Actuation
Opens and closes heavy material flow gates on batch plants, using the back rod end to simultaneously trip a mechanical limit valve.
Loader Attachment Sync
Synchronizes two attachment points from one piston, leveraging the double-rod geometry to maintain parallel motion without rotational drift.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X500 with the B04-SAID100X500
To replace the discontinued B04-SID100X500, use the SAID100X500 drop-in, which preserves the ISO 15552 mounting interface (Basic, FA, LB, TC) and G1/2 port. Size both ways by checking neighbor bores (80mm or 125mm) if you need to adjust the equal both-ways force. Choose a double-rod cylinder when you need anti-rotation stability or when the back rod must carry a sensor cam. Because this SKU has no -S magnet, it cannot support sensing; select a -S model if switches are needed. For the 500mm long stroke, add external guides to prevent rod-bending and side-load damage. Remember, air cushions only decelerate near stroke end; for load-holding on air loss, specify a SAIL/BSAI lock variant or external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID100X500
- ✓ 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-SID100X500 FAQ
Yes, the B04-SID100X500 (construction-machinery dedicated SID100X500) is discontinued. The exact drop-in replacement is the SAID100X500. It matches the ISO 15552 interface, 100mm bore, 500mm stroke, G1/2 port, and equal both-ways force, while adding an upgraded piston seal.
It features a G1/2 port and M20x1.5 rod thread. Because it is a double-rod cylinder, force is equal both ways: 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. It operates at 0.15-1.0 MPa with 36mm adjustable cushions and 30-800 mm/s speed.
