This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD50X60S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD50X60S 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 SUD50X60S
The AirTAC Airtac SUD Series Double Rod Cylinder SUD50X60S is a double-acting profile-type standard cylinder with a Ø50mm bore and 60mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD50X60S, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD50X60S
The AirTAC SUD50X60S is a double-acting, double-rod profile cylinder featuring a 50mm bore and 60mm stroke. 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 at 825N @0.5MPa, 1154N @0.7MPa, and 1484N @0.9MPa. This discontinued model is directly replaced by the SAUD50X60S, which retains the exact 1/4" port, M16x1.5 rod thread, and 21mm adjustable cushions.
Because the second rod drives a sensor cam and resists rotation, double-rod designs excel in multi-tool actuation. The built-in magnet (-S) supports legacy CS1-B/DS1-B switches, whereas the SAUD replacement uses current CMSG/DMSG/EMSG sensors. For sizing, the 825N @0.5MPa force yields a safe working load of roughly 495N, translating to a vertical lift capacity of about 42kg with a 2:1 margin. Note that cushions only decelerate; use an external rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD50X60S 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 SAUD50X60S 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.

| -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 SUD50X60S Is Used
Dual-Tool Transfer
Simultaneously drives two opposing tools from one compact profile body, utilizing the equal both-ways force to maintain balanced actuation.
Anti-Rotation Divert
The twin rods prevent piston twisting during side-loaded diverting tasks on packaging lines, ensuring precise component placement.
Symmetric Lift Station
Lifts platforms vertically with equal push and pull force, using the back rod to mount CS1-B/DS1-B sensors for end-of-stroke confirmation.
Replacing the Airtac SUD Series Double Rod Cylinder SUD50X60S with the SAUD50X60S
To replace the discontinued SUD50X60S, order the drop-in SAUD50X60S, matching the 50mm bore, 60mm stroke, and FA/LB mounting. When sizing both ways, verify the equal push/pull force fits your load, stepping to neighbouring bores (40mm or 63mm) if needed. Choose a double-rod cylinder when anti-rotation or a back rod for a sensor cam is required. For the -S magnet, upgrade from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG sensors. For strokes >=300mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUD50X60S
- ✓ 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 SUD50X60S FAQ
Yes, the SUD50X60S is discontinued. The exact drop-in replacement is the SAUD50X60S, which matches the 50mm bore, 60mm stroke, 1/4" port, and FA/LB mounting. You only need to upgrade the -S sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG.
The 1/4" port feeds a double-rod design where force is equal both ways: 825N @0.5MPa, 1154N @0.7MPa, and 1484N @0.9MPa. The 825N @0.5MPa rating provides a safe working load of about 495N, or a 42kg vertical lift with a 2:1 margin.
