This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAUD50X225 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAUD50X225 in place of this model. 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 B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X225
The AirTAC Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X225 is a double-acting profile-type standard cylinder with a Ø50mm bore and 225mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAUD50X225, which matches its bore, stroke, force and mounting.

About the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X225
The AirTAC B06-SUD50X225 is a double-acting, double-rod profile cylinder where the B06- prefix marks it as a battery-manufacturing dedicated variant, mechanically identical to the standard SUD50X225. A rod exits both ends on a single piston, meaning both faces use the rod-side area and push/pull force is equal at 825 N @0.5 MPa, 1154 N @0.7 MPa, and 1484 N @0.9 MPa. The extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same 50 mm bore. It features a 20 mm rod, M16x1.5 rod-end thread, 1/4" port, and 21 mm adjustable air cushions at each end.
This model is discontinued and the direct drop-in replacement is the SAUD50X225, which retains the exact bore, stroke, equal force, port, and FA/LB mounting. The SAUD upgrades to current CMSG/DMSG/EMSG sensors, whereas this legacy unit used CS1-B/DS1-B switches; note this specific SKU has no magnet and cannot take a switch. For sizing, the equal-both-ways 825 N @0.5 MPa force yields a safe working load of ~495 N (60% margin) and a vertical lift capacity of ~42 kg with a 2:1 safety factor. The air cushion only decelerates near stroke end; it does not hold loads on air loss, so an external rod lock is needed for holding.

Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The B06-SAUD50X225 produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X225 Is Used
Battery Cell Stacking
Drives precision stacking mechanisms in prismatic cell assembly, using the equal both-ways force to press and separate layers without repositioning delays.
Module Transfer
Actuates dual-sided pushers on a conveyor line for battery module handling, utilizing the double-rod's anti-rotation properties to keep packs aligned during indexing.
Tab Welding Press
Applies consistent clamping pressure for battery tab welding, with the second rod available to mount a mechanical cam or external stop for weld head sequencing.
Replacing the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X225 with the B06-SAUD50X225
To replace the discontinued B06-SUD50X225, drop in the SAUD50X225, which matches the 50 mm bore, 225 mm stroke, 825 N equal-both-ways force, 1/4" port, and FA/LB mounting. When sizing both ways, check neighbouring bores (40 mm or 63 mm) to ensure the equal push/pull force fits your application. A double-rod design is right when you need anti-rotation stability, want to drive two tools from one cylinder, or use the back rod as a sensor cam. Since this SKU lacks a magnet (-S), it cannot take sensors, but upgrading to the SAUD allows CMSG/DMSG/EMSG switches. For this 225 mm stroke (which is >=300 mm is false, but standard practice applies), ensure side-load alignment is within tolerance. Remember, the cushion decelerates but does not lock; use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → B06-SAUD50X225
- ✓ 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 B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X225 FAQ
Yes, this model is discontinued. The exact drop-in replacement is the SAUD50X225. The B06- prefix simply marks it as the battery-manufacturing dedicated variant of the SUD50X225, and the SAUD replacement shares the exact same 50 mm bore, 225 mm stroke, 1/4" port, and FA/LB mounting.
Because it is a double-rod cylinder, force is equal both ways: 825 N @0.5 MPa, 1154 N @0.7 MPa, and 1484 N @0.9 MPa. The port size is 1/4". The 825 N @0.5 MPa figure provides a safe working load of ~495 N and a vertical lift capacity of ~42 kg with a 2:1 margin.
