This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD63X200S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD63X200S 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 SUD63X200S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD63X200S is a double-acting profile-type standard cylinder with a Ø63mm bore and 200mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD63X200S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD63X200S
The AirTAC SUD63X200S is a double-acting, double-rod profile cylinder featuring a 63mm bore and 200mm stroke. A piston rod exits both ends, ensuring push and pull force is equal both ways at 1402N @0.5 MPa, 1962N @0.7 MPa, and 2523N @0.9 MPa. This model is discontinued; the exact drop-in replacement is the SAUD63X200S, which matches the 3/8 inch port, M16x1.5 rod thread, and FA/LB mounting. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore.
Because the rear rod can carry a sensor cam while the front rod drives a tool, this design prevents rotation without extra guides. With a 1402N force at 0.5 MPa, the computed safe working load is roughly 841N, and it can vertically lift about 71kg with a 2:1 margin. This SUD uses legacy CS1-B/DS1-B switches, whereas the SAUD successor uses current CMSG/DMSG/EMSG sensors. Note that air cushions only decelerate the piston; an external rod lock is required to hold loads on air loss.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD63X200S 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 SAUD63X200S 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.

| 63 | Bore size in mm. |
| ×200 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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 SUD63X200S Is Used
Dual-Station Processing
Drives two opposing tools simultaneously from a single piston, utilizing the equal both-ways force to machine or form parts on both ends of the 63mm bore cylinder.
Anti-Rotation Diverting
The twin rods prevent rotational twist during high-speed lateral pushing on a conveyor line, ensuring the 200mm stroke completes without binding or guide wear.
Symmetric Clamping
Applies equal clamping pressure from opposite sides using the 1402N @0.5 MPa force, holding irregular workpieces securely without deflecting the extruded profile barrel.
Replacing the Airtac SUD Series Double Rod Cylinder SUD63X200S with the SAUD63X200S
To replace the discontinued SUD63X200S, specify the SAUD63X200S drop-in, which preserves the 63mm bore, 200mm stroke, 3/8 inch port, and equal-both-ways force. If sizing both ways, the neighboring 50mm bore yields 825N @0.5 MPa, while the 80mm bore yields 2268N @0.5 MPa. A double-rod is right when you need anti-rotation stability or must drive two tools simultaneously. Mounting is limited to Basic, FA, and LB (SC-series compatible only). For the -S magnet option, change from CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. For this 200mm stroke, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUD63X200S
- ✓ 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 SUD63X200S FAQ
Yes, the SUD63X200S is discontinued. The exact drop-in replacement is the SAUD63X200S, which matches the 63mm bore, 200mm stroke, 3/8 inch port, and FA/LB mounting. You only need to update the legacy CS1-B/DS1-B sensors to the current CMSG/DMSG/EMSG switches.
Because it is a double-rod cylinder, force is equal both ways: 1402N @0.5 MPa, 1962N @0.7 MPa, and 2523N @0.9 MPa. Operating speed is 30-800 mm/s. The safe working load is roughly 841N, allowing a vertical lift of about 71kg with a 2:1 margin.
