This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAID100X700 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAID100X700 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-SID100X700
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X700 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 700mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B04-SAID100X700, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X700
The AirTAC B04-SID100X700 is a double-acting, double-rod ISO 15552 cylinder where the B04- prefix designates it as the construction-machinery dedicated variant of the base SID100X700, mechanically identical in every spec. Because a rod exits both ends on one piston, both faces use the rod-side area, making push and pull force equal at 3681 N @0.5 MPa. This model is discontinued; the exact drop-in replacement is the SAID100X700, matching the 100mm bore, 700mm stroke, G1/2 port, and M20x1.5 rod thread.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. A double rod provides anti-rotation stability and lets the back rod carry a sensor cam or drive two tools, though this non-S SKU cannot mount a magnetic switch. For sizing, the safe working load is ~2209 N (60% of the 3681 N force), allowing a vertical lift of ~188 kg with a 2:1 margin.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X700 Is Used
Excavator Actuation
Drives heavy construction machinery linkages where equal push and pull force is required for bidirectional digging or lifting operations.
Material Transfer
Simultaneously drives two conveyor sorting gates from a single centerline, utilizing the dual-rod output for synchronized material handling.
Guide Alignment
Maintains strict anti-rotation control during the extension and retraction of heavy structural alignment tools on heavy-equipment assembly lines.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X700 with the B04-SAID100X700
Replace the discontinued B04-SID100X700 directly with the SAID100X700, reusing the exact ISO 15552 mounting interface (Basic, FA, LB, TC) without bracket changes. Size both ways by checking neighbour bores; the 100mm bore yields equal both-ways force of 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. A double rod is right when you need anti-rotation or equal force on extension and retraction. Note this non-S model lacks a magnet for sensors. For the 700mm stroke, add external guides to prevent rod bending under side loads. A plain cylinder drifts on air loss; for held loads use an external rod lock or SAIL/BSAI variant.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID100X700
- ✓ 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-SID100X700 FAQ
Yes, the B04-SID100X700 is discontinued. The B04- prefix marks it as the construction-machinery dedicated variant of SID100X700. The exact drop-in replacement is the SAID100X700, which shares the identical ISO 15552 interface, 100mm bore, 700mm stroke, G1/2 port, and mounting, but adds an upgraded piston seal.
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. The air port is G1/2. The safe working load is ~2209 N, allowing a vertical lift of ~188 kg with a 2:1 margin.
