This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD50X200TC — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD50X200TC 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 SUD50X200TC
The AirTAC Airtac SUD Series Double Rod Cylinder SUD50X200TC is a double-acting profile-type standard cylinder with a Ø50mm bore and 200mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD50X200TC, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD50X200TC
The AirTAC SUD50X200TC is a discontinued double-acting double-rod profile cylinder featuring a 50mm bore, 200mm stroke, and a 1/4 inch air port. A rod exits both ends on a single piston, meaning both faces use the rod-side area and push/pull force is equal both ways (825N at 0.5MPa). The exact drop-in replacement is the SAUD50X200TC, retaining the same bore, stroke, force, port, and TC mounting interface.
Because the rear rod can carry a sensor cam or drive a second tool simultaneously, double-rod designs excel at anti-rotation tasks. Based on the 825N force at 0.5MPa, the computed safe working load is about 495N, yielding a vertical lift capacity of roughly 42kg with a 2:1 margin. Note this non-magnetic SKU cannot take a switch. The SAUD upgrade switches to current CMSG/DMSG/EMSG sensors from the legacy CS1-B/DS1-B used here.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD50X200TC 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 SAUD50X200TC 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 SUD50X200TC Is Used
Synchronized Tool Driving
Drives two opposing tools simultaneously from one piston, utilizing the equal both ways force for balanced machining or forming operations on both ends.
Anti-Rotation Transfer
The dual-rod geometry prevents piston rotation during traverse, ideal for moving parts between stations without linear guide rails.
Symmetric Ejection
Ejects workpieces symmetrically from a central fixture using the 825N force at 0.5MPa, ensuring balanced ejection without yawing.
Replacing the Airtac SUD Series Double Rod Cylinder SUD50X200TC with the SAUD50X200TC
To replace the discontinued SUD50X200TC, order the exact drop-in SAUD50X200TC, which matches the 50mm bore, 200mm stroke, 1/4 inch port, and TC mount. When sizing both ways, verify the equal both ways force fits your load, or step to neighbour bores (63mm or 40mm). Choose a double-rod cylinder when you need anti-rotation or to drive two tools. The SC-series TC mount is supported. This non-magnetic SKU cannot take a switch; the SAUD uses CMSG/DMSG/EMSG sensors. For strokes >=300mm, confirm the side-load line to prevent guide wear. A plain cylinder drifts on air loss; the cushion only decelerates, so use an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUD50X200TC
- ✓ 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 SUD50X200TC FAQ
Yes, the SUD50X200TC is discontinued. The exact drop-in replacement is the SAUD50X200TC, which matches the 50mm bore, 200mm stroke, equal both ways force, 1/4 inch port, and TC mounting.
Force is equal both ways: 825N at 0.5MPa, 1154N at 0.7MPa, and 1484N at 0.9MPa. The bore dictates a 1/4 inch air port. This non-magnetic SKU cannot take a switch.
