This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUD50X150SH — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUD50X150SH 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 SUD50X150SH
The AirTAC Airtac SUD Series Double Rod Cylinder SUD50X150SH is a double-acting profile-type standard cylinder with a Ø50mm bore and 150mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUD50X150SH, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD50X150SH
The AirTAC SUD50X150SH is a double-acting, double-rod profile cylinder featuring a 50mm bore, 150mm stroke, and a 1/4" 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). This unit is discontinued and the exact drop-in replacement is the SAUD50X150SH, which retains the same bore, stroke, force, port, and FA/LB mounting. The SUD50X150SH includes a piston magnet (-S) for legacy CS1-B/DS1-B switches, while the SAUD upgrade uses current CMSG/DMSG/EMSG sensors. This -H variant uses Viton/FKM seals, raising the operating temperature range from -20...+70C up to 0...150C.
Because the second rod acts as an anti-rotation guide and can carry a sensor cam or drive a second tool simultaneously, double-rod designs excel in compact synchronized tasks. The extruded aluminum profile barrel is shorter than a standard cylinder of the same bore. For sizing, the computed safe working load is approximately 495N (about 60% of the 825N at 0.5MPa figure), allowing a vertical lift of roughly 42kg with a 2:1 margin. Note that a plain cylinder does not hold loads on air loss; the 21mm adjustable air cushions only decelerate near stroke end, so an external rod lock is required for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD50X150SH 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 SAUD50X150SH 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 SUD50X150SH Is Used
Synchronized Tool Driving
Drives two opposing tools simultaneously from a single cylinder body using the equal-both-ways force of the dual rods.
Anti-Rotation Transfer
Transfers parts across a conveyor belt without rotational drift, using the second rod as a built-in guide.
High-Temperature Handling
Handles components in hot environments up to 150C, utilizing the Viton H seals and stable profile barrel.
Replacing the Airtac SUD Series Double Rod Cylinder SUD50X150SH with the SAUD50X150SH
To replace the discontinued SUD50X150SH, swap it directly with the SAUD50X150SH; bore, stroke, equal-both-ways force, 1/4" port, and FA/LB mounting remain identical. When sizing both ways, verify your force requirements against the 825N at 0.5MPa rating, stepping to the 63mm bore if more thrust is needed or dropping to the 40mm bore if less is required. A double-rod configuration is the right choice when you need anti-rotation stability or must drive two tools from one cylinder. For the -S magnet option, note the sensor change from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG on the SAUD. For this 150mm stroke (which is under 300mm), side-load alignment is less critical, but always ensure standard SC-series mounting compatibility.
Replacement checklist
- ✓ Same bore / stroke → SAUD50X150SH
- ✓ 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 SUD50X150SH FAQ
Yes, the SUD50X150SH is discontinued. The exact drop-in replacement is the SAUD50X150SH, which matches the 50mm bore, 150mm stroke, 1/4" port, and FA/LB mounting. You will only need to upgrade the piston magnet sensors from legacy CS1-B/DS1-B to the current CMSG/DMSG/EMSG switches.
Because it is a double-rod cylinder, the force is equal both ways and never quotes a larger single-rod push value. It outputs 825N at 0.5MPa, 1154N at 0.7MPa, and 1484N at 0.9MPa. Operating speed ranges from 30-800mm/s, with a 21mm adjustable air cushion at each end.
