This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAID100X160 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAID100X160 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-SID100X160
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X160 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 160mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B04-SAID100X160, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X160
The AirTAC B04-SID100X160 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, ensuring force is equal both ways at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The B04- prefix marks this as a construction-machinery dedicated variant of the base SID100X160, mechanically identical with a 100mm bore, 160mm stroke, G1/2 port, and M20x1.5 rod thread. This SID model is discontinued and is fully replaced by the SAID100X160.
The drop-in SAID100X160 retains the exact ISO 15552 interface, bore, stroke, and mounting options (Basic, FA, LB, TC, FTC, TCM1, TCM2) while adding an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. Because the second rod drives a sensor cam or a second tool while resisting rotation, the equal-both-ways force yields a safe working load of roughly 2209 N (60% of the 0.5 MPa figure) and a vertical lift capacity of about 188 kg with a 2:1 margin. Note this non-magnetic SKU cannot take a sensor switch, and the air cushion only decelerates; it does not hold loads on air loss.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X160 Is Used
Excavator Linkage Actuation
Uses the equal both-ways force of the 100mm bore to drive secondary construction-machinery linkage arms, relying on the double-rod geometry for anti-rotation stability under heavy soil engagement.
Crusher Feed Diverter
Simultaneously pushes and pulls a diverter gate on an aggregate conveyor using both rod ends, ensuring precise bidirectional material routing without requiring a larger single-rod push cylinder.
Heavy Equipment Brake Tester
Applies a balanced 3681 N clamping force at 0.5 MPa to test heavy machinery brake calipers, using the opposing rod to mount a load cell for direct equal-both-ways measurement.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X160 with the B04-SAID100X160
To replace the discontinued B04-SID100X160, select the SAID100X160, which matches the 100mm bore, 160mm stroke, G1/2 port, and 3681 N equal-both-ways force exactly. When sizing both ways, verify if neighbouring bores like 80mm (2268 N @0.5) or 125mm (5734 N @0.5) better suit your force requirements. A double-rod design is right when you need anti-rotation stability or must drive two tools simultaneously. Mounting reuses standard ISO 15552 FA, LB, or TC foot and clevis brackets. As this SKU lacks the -S magnet, it cannot accept sensors. For this 160mm stroke, side-load alignment is generally manageable, but for any stroke over 300mm, carefully guide the rod to prevent binding. Because air cushions only decelerate, use an external rod lock or pilot-operated check valve for load holding.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID100X160
- ✓ 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-SID100X160 FAQ
Yes, the B04-SID100X160 is discontinued. The exact drop-in replacement is the SAID100X160. The B04- prefix simply marks it as the construction-machinery dedicated variant of the SID100X160, and the SAID replacement shares the exact ISO 15552 interface, 100mm bore, 160mm stroke, G1/2 port, and mounting, while adding 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. It operates at 30-800 mm/s, uses a G1/2 port, and has 36mm adjustable air cushions at each end. The air cushion only decelerates near stroke end; it does not hold loads on air loss.
