This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAID100X175S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAID100X175S 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-SID100X175S
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X175S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 175mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B04-SAID100X175S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X175S
The AirTAC B04-SID100X175S is a double-acting, double-rod ISO 15552 cylinder where the B04- prefix marks it as the construction-machinery dedicated variant of the base SID100X175S, mechanically identical to it. A rod exits both ends on one piston, meaning both faces use the rod-side area and push/pull force is equal both ways (3681 N @0.5 MPa, 5153 N @0.7 MPa, 6626 N @0.9 MPa). It features a 25 mm piston rod, M20x1.5 rod-end thread, adjustable 36 mm air cushions at each end, and a G1/2 port. This model is discontinued and the exact drop-in replacement is the SAID100X175S.
The SAI replacement family uses an upgraded piston seal (two Y-shaped one-way elements for long life and low start-up pressure) and adds SAIL (air-released lock) and BSAI (clamp-lock) variants the SI line lacked. Because the second rod can carry a sensor cam or drive two tools while resisting rotation, it suits heavy-equipment frames. Computed buyer insight: safe working load is ~2209 N (60% of the 3681 N @0.5 MPa figure) and vertical lift is ~188 kg with a 2:1 margin. A plain cylinder does not hold loads on air loss; the cushion only decelerates near stroke end, so use an external rod lock for held loads.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X175S Is Used
Excavator Boom Actuation
Fits construction-machinery frames requiring equal push/pull force on both strokes, using the back rod to drive a secondary tool while resisting rotational twist.
Heavy-Equipment Clamp
Drives synchronized clamping jaws on heavy-equipment assemblies where the double-rod geometry maintains precise alignment without lateral drift.
Sensor Cam Tracking
Uses the rear protruding rod to carry a sensor cam for position feedback, leaving the front rod free to apply equal force both ways in tight machine spaces.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X175S with the B04-SAID100X175S
To replace the discontinued B04-SID100X175S, specify the SAID100X175S (insert an A after the leading S). It preserves the ISO 15552 mounting interface, 100 mm bore, 175 mm stroke, G1/2 port, and equal-both-ways force. When sizing both ways, compare neighbouring bores (like 80 mm or 125 mm) to ensure the equal push/pull force fits your circuit. A double rod is right when you need anti-rotation stability or a back rod to carry a sensor cam. Reuse FA, LB, or TC mounts; the -S suffix means the piston magnet is present for CS1-B/DS1-B switches (the SAI replacement uses current AirTAC switches). For stroke lengths >=300 mm, verify side-load bearing limits.
Replacement checklist

- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
