This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X30TC, 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 SU50X30TC
The AirTAC SU32~50 Standard Cylinder SU50X30TC is a double-acting profile-type standard cylinder with a Ø50mm bore and 30mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X30TC, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X30TC
The AirTAC SU50X30TC is a discontinued double-acting profile-type standard cylinder with a 50mm bore and 30mm stroke. It delivers 982 N push force at 0.5 MPa through a 1/4" port. AirTAC replaced this legacy unit with the SAU50X30TC, a direct upgrade retaining the exact bore, stroke, output force, port size, M16x1.5 rod thread and TC mounting interface.
Because this non-magnetic SKU lacks a sensor groove, it cannot accept a piston switch. The SAU upgrade introduces modern CMSG/DMSG/EMSG sensors on its -S variants and offers a SAUF built-in 4M valve option the SU line never had. The extruded aluminum profile is more compact than an ISO 15552 cylinder of the same bore, sharing AirTAC SC-series accessories.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X30TC 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 SAU50X30TC 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 SU50X30TC Is Used
Short-Stroke Clamping
Ideal for holding parts during machining or welding, using the 982 N push force to secure components firmly within a tight 30mm travel envelope.
Package Diverting
Provides a fast, compact actuation for sorting lightweight goods on a conveyor line, where the short 30mm stroke quickly pushes items into branching lanes.
Pallet Stopper Gate
Functions as a pneumatic stop in material handling systems, extending 30mm to halt pallet movement using the TC mount for secure side-rail installation.
Replacing the Airtac SU32~50 Standard Cylinder SU50X30TC with the SAU50X30TC
To replace the SU50X30TC, order the SAU50X30TC. Verify your 1/4" port thread (PT, G or NPT) and confirm the TC mounting accessory is reused. Since this specific SKU has no magnet (-S), it cannot support sensing; if you need position detection on the new unit, specify an SAU50X30TC-S and migrate to CMSG/DMSG/EMSG switches. For loads requiring holding on air loss, add an external rod lock or pilot-operated check valve, as the adjustable 21mm cushions only decelerate the piston. If downsizing, a 40mm bore yields 628 N push at 0.5 MPa; if upsizing, a 63mm bore provides 1559 N. The 30mm stroke keeps the assembly highly compact without rod-bending side-load risks.
Replacement checklist
- ✓ Same bore / stroke → SAU50X30TC
- ✓ 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 SU50X30TC FAQ
Yes, the SU50X30TC is discontinued. The direct replacement is the AirTAC SAU50X30TC. It matches the 50mm bore, 30mm stroke, 1/4" port, 982 N force and TC mounting, so it fits the same application without modifications.
At 0.5 MPa it pushes 982 N and pulls 825 N; at 0.7 MPa it pushes 1374 N, with a theoretical max of 200 kgf at 1.0 MPa. This specific non-S SKU cannot take a sensor. The SAU replacement supports CMSG/DMSG/EMSG switches on its -S variants.
