This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X45, 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 SU50X45
The AirTAC Airtac SU32~50 Standard Cylinder SU50X45 is a double-acting profile-type standard cylinder with a Ø50mm bore and 45mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X45, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X45
The AirTAC SU50X45 is a discontinued double-acting profile-type cylinder with a 50mm bore and 45mm stroke. It delivers 982 N push and 825 N pull at 0.5 MPa using a 1/4" port. AirTAC replaced this legacy unit with the SAU50X45, a direct sharing the exact same body dimensions, output force, and SC-series mounting accessories.
Because this SKU lacks a magnet, it cannot accept a piston switch. The SAU upgrade additionally offers a SAUF variant with a built-in 4M solenoid valve the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X45 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 SAU50X45 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 SU50X45 Is Used
Clamping Medium Parts
Applies up to 982 N of push force at 0.5 MPa to secure 50 kg workpieces during machining or assembly operations.
Short Stroke Diverting
Uses the compact 45mm stroke to push lightweight cartons or components between adjacent conveyor lanes.
Package Ejection
Provides rapid 30-800 mm/s ejection of verified goods off a packing line using the 1/4" air port.
Replacing the Airtac SU32~50 Standard Cylinder SU50X45 with the SAU50X45
To replace this SU50X45, order the SAU50X45 with the identical 50mm bore, 45mm stroke, 1/4" port, M16x1.5 rod thread, and SC-series mounting. Confirm your thread standard (PT, G, or NPT) when ordering. Without a -S suffix, this non-magnetic SKU cannot support sensing; if you need position detection on the new SAU, add the magnet and use current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. If your application needs more force, the neighboring 63mm bore provides 1559 N push at 0.5 MPa; if less is required, the 40mm bore offers 628 N. For any load that must be held without live air, add an external rod lock or pilot-operated check valve, as the adjustable cushions only decelerate at stroke end.
Replacement checklist
- ✓ Same bore / stroke → SAU50X45
- ✓ 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 SU50X45 FAQ
Yes, the SU50X45 is discontinued. The direct replacement is the AirTAC SAU50X45. It shares the same 50mm bore, 45mm stroke, 982 N push force at 0.5 MPa, 1/4" port, and SC-series mounting, so it fits your existing setup perfectly.
At 0.5 MPa it provides 982 N push and 825 N pull; at 0.7 MPa it pushes 1374 N, with a theoretical max of 200 kgf at 1.0 MPa. This specific SKU has no magnet, so it cannot take a sensor. If you need detection on the SAU replacement, order the -S version which uses CMSG/DMSG/EMSG switches.
