This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement B04-SAID63X160S, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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-SID63X160S
The AirTAC B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID63X160S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 160mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the B04-SAID63X160S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID63X160S
The AirTAC B04-SID63X160S is a double-acting, double-rod ISO 15552 cylinder where the B04- prefix designates it as a construction-machinery dedicated variant of the base SID63X160S. Because a rod exits both ends, the working area is identical on extension and retraction, yielding equal force both ways (1402 N at 0.5 MPa). This model is discontinued; the direct replacement is the SAID63X160S, which reuses the same G3/8 port, M16x1.5 rod thread, and ISO 15552 mounting interface.
The SAI upgrade introduces a two-piece Y-shaped piston seal for lower start-up pressure and longer life. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches. Note that a plain cylinder cannot hold loads on air loss; the adjustable 30 mm cushions only decelerate near stroke end, so external rod locks are needed for held loads.

Where the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID63X160S Is Used
Excavator Linkage Actuation
Drives dual-tool mechanisms on heavy equipment where equal extension and retraction force is required to maintain balanced hydraulic-like motion in pneumatic pilot circuits.
Construction Material Transfer
Pushes and pulls heavy building components from both ends of a conveyor station, utilizing the equal-both-ways force to return the carriage without a secondary cylinder.
Heavy-Duty Guide Alignment
Uses the twin rods exiting both end caps to resist rotational torque and maintain precise alignment of structural jigs during off-highway vehicle frame assembly.
Replacing the Airtac B04-SID Construction Machinery Special ISO Standard Cylinder B04-SID63X160S with the B04-SAID63X160S
To replace the discontinued B04-SID63X160S, specify the SAID63X160S, which matches the 63 mm bore, 160 mm stroke, G3/8 port, and ISO 15552 mounting dimensions (Basic, FA, LB, TC). When sizing, remember the double-rod design yields equal force both ways (1402 N @0.5 MPa, 1962 N @0.7 MPa, 2523 N @0.9 MPa). If you need slightly more or less thrust, evaluate the neighboring 80 mm or 50 mm bores. The -S magnet enables position sensing. For strokes of 300 mm or longer, verify side-load limits to prevent guide bushing wear. For suspended loads that must not drift on air loss, use an external rod lock or the SAIL/BSAI lock variant, as cushions only decelerate.
Replacement checklist
- ✓ Same ISO 15552 interface → B04-SAID63X160S
- ✓ 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-SID63X160S FAQ
Yes, the B04-SID63X160S is discontinued. The direct replacement is the SAID63X160S. The B04- prefix simply marks it as construction-machinery dedicated, so mechanically it is identical to the base SID63X160S. The SAID replacement shares the same ISO 15552 interface, 63 mm bore, 160 mm stroke, G3/8 port, and mounting options.
Because it is a double-rod cylinder, force is equal both ways: 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa. The bore dictates a G3/8 air port, a 20 mm piston rod with an M16x1.5 thread, and a 30 mm adjustable cushion at each end. Operating speed is 30-800 mm/s.
