This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X450FA, 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 SU50X450FA
The AirTAC Airtac SU32~50 Standard Cylinder SU50X450FA is a double-acting profile-type standard cylinder with a Ø50mm bore and 450mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X450FA, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X450FA
The AirTAC SU50X450FA is a discontinued double-acting profile cylinder with a 50mm bore and 450mm stroke. It delivers 982N push and 825N pull at 0.5MPa via a 1/4" port. The direct replacement is the SAU50X450FA, matching the bore, stroke, force, port, and SC-series FA mounting.
This extruded aluminum profile is more compact than an ISO 15552 cylinder. Because this SKU lacks a magnet, it cannot take a sensor; the SAU upgrade supports CMSG/DMSG/EMSG switches and a SAUF valve-integrated option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X450FA 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 SAU50X450FA 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 SU50X450FA Is Used
Package Diversion
Uses the 982N push force at 0.5MPa to deflect medium cartons on a sorting line, with the 450mm stroke providing full lane clearance.
Pallet Push-Off
Leverages the 50kg vertical lift capacity to eject goods from an accumulator, while the FA mount secures the body to the machine frame.
Component Ejection
Employs the 450mm travel to push machined parts completely clear of a CNC enclosure before the next cycle begins.
Replacing the Airtac SU32~50 Standard Cylinder SU50X450FA with the SAU50X450FA
To replace this SU50X450FA, order the SAU50X450FA. Confirm the 1/4" port, M16x1.5 rod thread, PT/G/NPT thread type, and the FA mounting accessory. This no-magnet SKU cannot accept a sensor; if sensing is needed, specify an SAU-S model and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. For the 450mm stroke, use an external guide to prevent rod bending under side loads. A plain cylinder drifts on air loss, so use a rod lock for held loads. The SAUF variant adds a built-in valve the SU lacked. Neighboring bores: 40mm gives 628N push, 63mm gives 1559N push at 0.5MPa.
Replacement checklist
- ✓ Same bore / stroke → SAU50X450FA
- ✓ 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 SU50X450FA FAQ
Yes, the SU50X450FA is discontinued. The direct replacement is the SAU50X450FA. It matches the 50mm bore, 450mm stroke, 982N force, 1/4" port, and SC-series FA mounting. You just order the SAU equivalent.
At 0.5MPa it pushes 982N and pulls 825N; at 0.7MPa it pushes 1374N; max force is 200kgf at 1.0MPa. The 21mm cushions only decelerate the piston near stroke end. The cylinder will drift on air loss, so use an external rod lock or pilot-operated check valve to hold a load.
