This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B04-SAID100X160S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B04-SAID100X160S 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-SID100X160S
The AirTAC Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X160S 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-SAID100X160S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X160S
The AirTAC B04-SID100X160S is a double-acting, double-rod ISO 15552 cylinder where the B04- prefix designates it as a construction-machinery dedicated variant of the base SID100X160S, mechanically identical in every spec. A rod exits both ends on a single piston, meaning both faces use the rod-side area and push/pull force is equal at 3681 N @0.5 MPa. The bore is 100 mm, the port is G1/2, and it features an M20x1.5 rod thread. This SID model is discontinued and the exact drop-in replacement is the SAID100X160S, which reuses the same ISO 15552 mounting interface, bore, stroke, and porting.
The SAID upgrade introduces an improved piston seal using two Y-shaped one-way elements for low start-up pressure and long life. Because the second rod can drive two tools or carry a sensor cam while resisting rotation, double-rod designs offer distinct mechanical advantages. Based on the 3681 N force at 0.5 MPa, the computed safe working load is approximately 2209 N (60%), translating to a vertical lift capacity of about 188 kg with a 2:1 margin. Note that a plain cylinder does not hold loads on air loss; the adjustable 36 mm cushions only decelerate near stroke end, so use an external rod lock for held loads.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X160S Is Used
Excavator Linkage Actuation
Drives synchronized dual-tool mechanisms on heavy equipment with equal push/pull force, leveraging the robust 100 mm bore and anti-rotation properties for precise linkage control.
Crusher Feed Control
Regulates material flow in construction-machinery crushers. The back rod carries a sensor cam for position feedback while the front rod modulates the heavy feed gate.
Paver Screed Adjustment
Provides stable, equal-both-ways positioning for asphalt paver screeds. The double-rod design ensures consistent paving width adjustments under high vibration.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID100X160S with the B04-SAID100X160S
To replace the discontinued B04-SID100X160S, order the SAID100X160S (inserting an A after the S), which is a true drop-in upgrade retaining the G1/2 port, M20x1.5 thread, and 36 mm cushion. Size both directions by verifying the equal force requirement: this 100 mm bore delivers 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. If sizing down, check the 80 mm bore (2268 N @0.5 MPa); if sizing up, check the 125 mm bore (5734 N @0.5 MPa). A double rod is right when you need anti-rotation, dual-tool driving, or a back rod for sensor cams. Mounting options include Basic, FA, LB, and TC. The -S suffix means a piston magnet is present for CS1-B/DS1-B switches. For this 160 mm stroke side-load is minimal, but for strokes >=300 mm ensure guide alignment to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID100X160S
- ✓ 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-SID100X160S FAQ
Yes, the B04-SID100X160S is discontinued. The B04- prefix marks it as a construction-machinery dedicated variant of the base SID100X160S. The exact drop-in replacement is the SAID100X160S, which shares the identical ISO 15552 interface, 100 mm bore, 160 mm stroke, G1/2 port, and mounting. The SAI family also adds upgraded piston seals and SAIL/BSAI lock variants.
Because it is a double-rod cylinder, force is equal both ways (no larger single-rod push value): 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The air port is G1/2. Note that air cushions only decelerate the load; they do not hold it on air loss, so an external rod lock is needed for held loads.
