This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X550SLB, 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 SU32X550SLB
The AirTAC SU32~50 Standard Cylinder SU32X550SLB is a double-acting profile-type standard cylinder with a Ø32mm bore and 550mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X550SLB, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X550SLB
The AirTAC SU32X550SLB is a discontinued double-acting profile-type cylinder with a 32mm bore and 550mm stroke. Delivering 402 N push and 345 N pull at 0.5 MPa, it features an extruded aluminum barrel and adjustable air cushions at both ends. The direct replacement is the SAU32X550SLB, matching the 1/8" port, M10x1.25 rod thread, and SC-series LB mounting.
This compact profile body is shorter than an ISO 15552 cylinder of the same bore. Because your SKU includes the -S magnet, note the SAU upgrade switches from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. The SAU family also adds a SAUF built-in 4M solenoid valve option the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X550SLB carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAU32X550SLB 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 SU32X550SLB Is Used
Package Diversion
Ideal for routing small lightweight cartons on a packing line where the 550mm extension pushes items cleanly into a sorting chute.
Bin Push-Off
Provides the linear travel needed to eject compact components from a storage rack using a guided mechanical pusher.
Small Part Ejection
Suitable for pushing molded parts out of a low-force press fixture, utilizing the full 550mm stroke to clear the machine bed.
Replacing the Airtac SU32~50 Standard Cylinder SU32X550SLB with the SAU32X550SLB
To replace this SU32X550SLB, order the SAU32X550SLB direct equivalent, verifying the 32mm bore, 550mm stroke, 1/8" port, and LB mounting interface are retained. If sizing alternatives, the adjacent 40mm bore yields 628 N push at 0.5 MPa, while dropping down requires checking your exact load. The 550mm stroke mandates an external guide to prevent rod bending under side loads. A plain cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for load holding. For automated setups, explore the SAUF valve-integrated variant.
Replacement checklist
- ✓ Same bore / stroke → SAU32X550SLB
- ✓ 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 SU32X550SLB FAQ
Yes, the SU32X550SLB is discontinued. The direct replacement is the AirTAC SAU32X550SLB. It shares the same 32mm bore, 550mm stroke, 402 N output force at 0.5 MPa, 1/8" port, and SC-series LB mounting. The main upgrade is that the SAU uses CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The 32mm bore features a 1/8" port and M10x1.25 rod thread. Theoretical forces are 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, 724 N push at 0.9 MPa, and a maximum force of 82 kgf at 1.0 MPa.
