This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B06-SAUD50X25 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B06-SAUD50X25 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-SUD50X25
The AirTAC Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X25 is a double-acting profile-type standard cylinder with a Ø50mm bore and 25mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the B06-SAUD50X25, which matches its bore, stroke, force and mounting.

About the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X25
The AirTAC B06-SUD50X25 is a double-acting, double-rod profile cylinder where the B06- prefix designates it as a battery-manufacturing dedicated variant of the base SUD50X25, mechanically identical in every spec. A rod exits both ends on a single piston, meaning push and pull force are equal at 825 N @0.5 MPa, 1154 N @0.7 MPa, and 1484 N @0.9 MPa. The extruded aluminum profile barrel is more compact than an ISO 15552 cylinder of the same bore. This SUD series is discontinued and the direct drop-in replacement is the SAUD50X25, which retains the 50mm bore, 25mm stroke, 1/4" port, and FA/LB mounting.
Because force is equal both ways, this cylinder is ideal for driving two tools or opposing stations simultaneously without force imbalance. The rear rod extension can also carry a sensor cam for stroke confirmation, though this specific SKU lacks a magnet (-S) and cannot accept magnetic switches. For sizing, the 825 N @0.5 MPa output yields a safe working load of roughly 495 N (60% of force) and a vertical lift capacity of about 42 kg with a 2:1 safety margin. Note that a standard cylinder does not hold loads on air loss; the adjustable 21mm cushions only decelerate near stroke end, so an external rod lock is required for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The B06-SAUD50X25 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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-SAUD50X25 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.

Legacy SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Where the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X25 Is Used
Cell Stacking Press
Applies equal both-ways force for prismatic cell stacking and unstacking, using the twin rods to maintain parallel platen alignment without rotation.
Module Transfer Handler
Drives opposing pincer jaws on a battery module assembly conveyor, utilizing the compact profile barrel to fit within tight machine cell footprints.
Tab Welding Clamp
Synchronizes dual clamping tools for battery tab welding, ensuring balanced pressure on both sides of the cell terminal during the joining process.
Replacing the Airtac B06-SUD Battery Dedicated Standard Cylinder B06-SUD50X25 with the B06-SAUD50X25
To replace the discontinued B06-SUD50X25, select the drop-in SAUD50X25, which matches the 50mm bore, 25mm stroke, 1/4" port, M16x1.5 rod thread, and FA/LB mounting. If sizing both ways, neighbor bores are 40mm (528/739/950 N) and 63mm (1402/1962/2523 N); verify your equal-both-ways force fits this range. A double rod is right when you need anti-rotation rigidity, synchronous dual-tool driving, or a back-rod sensor cam. This non-magnetic SKU cannot take sensors, but upgrading to an -S SAUD requires switching from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors. For strokes >=300mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → B06-SAUD50X25
- ✓ 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-SUD50X25 FAQ
Yes, the B06-SUD50X25 (battery-manufacturing dedicated SUD50X25) is discontinued. The exact drop-in replacement is the SAUD50X25. It matches the 50mm bore, 25mm stroke, 1/4" port, and FA/LB mounting. The SAUD also supports the SAUF built-in-valve variant the SU line lacked.
Being double-rod, force is equal both ways: 825 N @0.5 MPa, 1154 N @0.7 MPa, and 1484 N @0.9 MPa. Speed is 30-800 mm/s. The 1/4" port and 21mm adjustable cushions handle deceleration, but do not hold loads on air loss.
