This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X140TC, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 SU32~50 Standard Cylinder SU50X140TC
The AirTAC SU32~50 Standard Cylinder SU50X140TC is a double-acting profile-type standard cylinder with a Ø50mm bore and 140mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X140TC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X140TC
The AirTAC SU50X140TC is a discontinued double-acting profile-type cylinder featuring a 50mm bore, 140mm stroke, 1/4" port, and an SC-series TC mounting interface. Delivering 982 N push force at 0.5 MPa, it is replaced by the SAU50X140TC. This direct successor matches the exact bore, stroke, output force, port size, and TC mount, ensuring a seamless swap.
The SAU upgrade brings current CMSG/DMSG/EMSG sensors (this non-magnetic SU SKU lacks a magnet groove and cannot take switches) and introduces the SAUF built-in 4M valve variant. The extruded aluminium body is more compact than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X140TC 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 SAU50X140TC produces the same force from the same bore. 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 SU32~50 Standard Cylinder SU50X140TC Is Used
Package Diverting
Actuates a TC-mounted diverting arm on a packaging line, using the 982 N push force at 0.5 MPa to reliably push 50 kg cartons off the main belt.
Pallet Stop Gate
Controls a 140mm stroke stop gate for low-profile pallets, taking advantage of the compact profile body to fit within tight conveyor frame clearances.
Clamp Actuation
Drives a secondary clamping fixture in an assembly cell, delivering 825 N pull force to hold components securely during machining operations.
Replacing the Airtac SU32~50 Standard Cylinder SU50X140TC with the SAU50X140TC
To replace this discontinued SU50X140TC, order the SAU50X140TC direct, verifying the 1/4" port, M16x1.5 rod thread, and TC mounting. Because this specific SKU has no magnet (-S), it cannot accept position switches; if sensing is now required, specify an SAU50X140TCS and migrate to CMSG/DMSG/EMSG sensors. For load holding, note that the adjustable 21mm cushions only decelerate the piston—they do not lock it on air loss; use an external rod lock or pilot-operated check valve for vertical safety. If downsizing, a 40mm bore yields 628 N push; if upsizing, a 63mm bore provides 1559 N. At 140mm stroke, side-load risk is low, but ensure guide alignment to prevent rod bending.
Replacement checklist
- ✓ Same bore / stroke → SAU50X140TC
- ✓ 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 SU32~50 Standard Cylinder SU50X140TC FAQ
Yes, the SU50X140TC is discontinued. The direct replacement is the SAU50X140TC. It shares the identical 50mm bore, 140mm stroke, 982 N output force, 1/4" port, and TC mounting, so it bolts right in. The SAU body also introduces the option of a built-in 4M solenoid valve (SAUF variant) the SU line never had.
The 50mm bore delivers 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a theoretical max of 200 kgf at 1.0 MPa. Because this specific SU50X140TC SKU lacks a magnet, it cannot accept legacy CS1-B/DS1-B switches. If sensing is needed, order the SAU50X140TCS replacement and use current CMSG/DMSG/EMSG sensors.
