This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD63X100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD63X100 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 SUD63X100
The AirTAC Airtac SUD Series Double Rod Cylinder SUD63X100 is a double-acting profile-type standard cylinder with a Ø63mm bore and 100mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD63X100, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD63X100
The AirTAC SUD63X100 is a discontinued double-acting profile cylinder featuring a rod exiting both ends. This design yields equal force in both directions, outputting 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 cylinder of the same bore. It features a 63 mm bore, 100 mm stroke, a 20 mm piston rod, and a 3/8 inch port.
As this SUD series is end-of-life, the direct drop-in replacement is the SAUD63X100. The SAUD maintains the exact bore, stroke, 3/8 inch port, and FA/LB mounting footprint, but upgrades to current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here. Because this specific SKU lacks a magnet, it cannot accept any magnetic sensor. For sizing, the 1402 N force at 0.5 MPa yields a safe working load of roughly 841 N, or a vertical lift capacity of about 71 kg with a 2:1 margin. Note that air cushions only decelerate the piston near stroke end; an external rod lock is required to hold loads securely.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD63X100 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 SAUD63X100 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 SUD63X100 Is Used
Dual-Tool Machining Station
Drives two opposing tools simultaneously from a single piston, utilizing the equal both-ways force to machine parts on both ends of the stroke efficiently.
Anti-Rotation Transfer Gate
Uses the twin rods exiting both ends to prevent mechanical rotation during lateral transfers on a packaging line, ensuring smooth product handling without binding.
Balanced Vertical Lift
Lifts loads vertically with equal push and pull force, taking advantage of the 71 kg vertical lift capacity at 0.5 MPa for stable, balanced material handling.
Replacing the Airtac SUD Series Double Rod Cylinder SUD63X100 with the SAUD63X100
To replace the discontinued SUD63X100, install the drop-in SAUD63X100, which preserves the 63 mm bore, 100 mm stroke, 3/8 inch port, and FA/LB mounting compatibility. When sizing both ways, verify the equal push/pull force matches your needs: this 63 mm bore delivers 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa. If margins are tight, check the neighboring 50 mm or 80 mm bores. Choose a double-rod cylinder when you need anti-rotation stability or need to drive two tools simultaneously from one piston. If your application requires position sensing, note that this non-magnetic SKU cannot take a switch, whereas the SAUD replacement uses current CMSG/DMSG/EMSG sensors. For strokes at or above 300 mm, carefully manage side-load alignment to prevent guide wear. Finally, remember that air cushions only decelerate the load; use an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUD63X100
- ✓ 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 SUD63X100 FAQ
Yes, the AirTAC SUD63X100 is discontinued. The exact drop-in replacement is the SAUD63X100. It offers the same 63 mm bore, 100 mm stroke, 3/8 inch port, and equal both-ways force, but uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
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 air port size is 3/8 inch. This non-magnetic SKU cannot accept a sensor.
