This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD63X1350 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD63X1350 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 SUD Series Double Rod Cylinder SUD63X1350
The AirTAC Airtac SUD Series Double Rod Cylinder SUD63X1350 is a double-acting profile-type standard cylinder with a Ø63mm bore and 1350mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD63X1350, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD63X1350
The AirTAC SUD63X1350 is a double-acting, double-rod profile cylinder featuring a 63mm bore and 1350mm stroke. A rod exits both ends on a single piston, meaning both faces use the rod-side area and push/pull force is equal at 1402N @0.5MPa, 1962N @0.7MPa, and 2523N @0.9MPa. This discontinued model is directly replaced by the SAUD63X1350, which retains the exact 3/8" port, M16x1.5 rod thread, and FA/LB mounting. The extruded aluminum profile barrel is shorter than an ISO 15552 cylinder of the same bore.
Because the second rod acts as an anti-rotation guide and can drive a second tool simultaneously, double-rod designs excel in compact sync-driven setups. For this specific SKU, the safe working load is approximately 841N (60% of the 0.5MPa force), yielding a vertical lift capacity of about 71kg with a 2:1 margin. Note that this non-magnetic unit cannot accept switches (legacy SUD used CS1-B/DS1-B; the SAUD uses CMSG/DMSG/EMSG). The 21mm adjustable cushions only decelerate near stroke end; they do not hold loads on air loss, so an external rod lock is required for holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD63X1350 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAUD63X1350 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 SUD Series Double Rod Cylinder SUD63X1350 Is Used
Dual-End Transfer Pusher
Simultaneously pushes a workpiece from both ends on a conveyor line, utilizing the equal both-ways force to keep synchronized movement without twisting.
Anti-Rotation Gripper Slide
Drives a precision machining gripper where the second rod prevents rotational play, ensuring the tool maintains strict alignment during the 1350mm travel.
Vertical Lift Fixture
Lifts a 71kg fixture vertically using the 0.5MPa safe working load, relying on the double-rod symmetry to maintain platform stability throughout the stroke.
Replacing the Airtac SUD Series Double Rod Cylinder SUD63X1350 with the SAUD63X1350
To replace this discontinued SUD63X1350, order the SAUD63X1350 drop-in equivalent (insert an A after the leading S) to keep the identical 63mm bore, 1350mm stroke, 3/8" port, and FA/LB mounting. When sizing both ways, verify your force requirements against the equal push/pull output of 1402N @0.5MPa; if you need less force, step down to the 50mm bore, or step up to the 80mm bore for higher loads. Choose a double-rod cylinder when you need anti-rotation stability or must drive two tools from one actuator. If upgrading to the SAUD and adding sensors, remember this non-magnetic SKU cannot accept them, but the SAU family supports current CMSG/DMSG/EMSG switches. Finally, at 1350mm stroke, lateral side-load and rod-bending forces are significant, so external guide rails must be used to prevent premature seal wear.
Replacement checklist
- ✓ Same bore / stroke → SAUD63X1350
- ✓ 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 SUD Series Double Rod Cylinder SUD63X1350 FAQ
Yes, the SUD63X1350 is discontinued. The exact drop-in replacement is the SAUD63X1350, which matches the 63mm bore, 1350mm stroke, 3/8" port, and FA/LB mounting. The SAUD also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
Because it is a double-rod cylinder, the force is equal both ways: 1402N @0.5MPa, 1962N @0.7MPa, and 2523N @0.9MPa. The air port is 3/8" (PT thread). Note that the 21mm adjustable cushions only decelerate the load near stroke end and do not hold the load on air loss.
