This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement B04-SAUD100X100, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.
Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD100X100
The AirTAC Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD100X100 is a double-acting profile-type standard cylinder with a Ø100mm bore and 100mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the B04-SAUD100X100, which matches its bore, stroke, force and mounting.

About the Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD100X100
The AirTAC B04-SUD100X100 is a double-acting, double-rod profile cylinder where a rod exits both ends, generating equal force in both directions (3681 N at 0.5 MPa). The B04- prefix marks this as a construction-machinery dedicated variant of the base SUD100X100, mechanically identical with a 100mm bore, 100mm stroke, and 1/2" port. This discontinued profile barrel is shorter than an ISO 15552 cylinder of the same bore and uses adjustable 29mm cushions at each end.
As the SUD line is end-of-life, the direct replacement is the SAUD100X100, preserving the bore, stroke, equal-both-ways force, and FA/LB mounting. The double-rod design prevents rotation and allows driving two tools simultaneously, though this specific non-magnetic SKU cannot accept position sensors. Note that air cushions only decelerate the piston; an external rod lock is required to hold loads securely.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |

Where the Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD100X100 Is Used
Excavator Actuation
Drives dual opposing tools or heavy covers on construction machinery where equal push and pull force is mandatory and space is restricted.
Heavy Press Transfer
Moves heavy structural components between stations with high bidirectional force, utilizing the anti-rotation properties of the dual rods.
Equipment Clamping
Secures large fabrications during machining, using the 100mm bore to deliver 3681 N of clamping force at 0.5 MPa in both directions.
Replacing the Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD100X100 with the B04-SAUD100X100
To replace the discontinued B04-SUD100X100, select the SAUD100X100, which offers identical bore, stroke, 1/2" port, M20x1.5 rod thread, and equal-both-ways force. If sizing both ways, verify if neighbouring bores (like 80mm) provide sufficient force, or step up if higher capacity is needed. Choose a double-rod cylinder when anti-rotation or driving two tools is required. Mounting is limited to Basic, FA, and LB styles. Because this SKU lacks a magnet, it cannot use sensors, but legacy CS1-B/DS1-B switches on other variants transition to CMSG/DMSG/EMSG sensors on the SAUD. For strokes of 300mm or longer, carefully manage side-load alignment to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → B04-SAUD100X100
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac B04-SUD Construction Machinery Special Standard Cylinder B04-SUD100X100 FAQ
Yes, the B04-SUD100X100 is discontinued. The direct replacement is the SAUD100X100. The B04- prefix simply denotes the construction-machinery dedicated variant of the SUD100X100, and the SAUD matches its bore, stroke, 1/2" port, and force exactly.
Because it is a double-rod cylinder, force is equal both ways: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. It features a 1/2" port, a 25mm rod, and adjustable 29mm cushions. The air cushion only decelerates the piston near stroke end; it does not hold loads on air loss.
