This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X160, 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 SU50X160
The AirTAC SU32~50 Standard Cylinder SU50X160 is a double-acting profile-type standard cylinder with a Ø50mm bore and 160mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X160, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X160
The AirTAC SU50X160 is a discontinued double-acting profile-type cylinder with a 50mm bore and 160mm stroke. It delivers 982 N push and 825 N pull at 0.5 MPa, operating at 30-800 mm/s through a 1/4" port. AirTAC replaced this legacy unit with the SAU50X160 direct replacement, matching the exact bore, stroke, output force, port size and SC-series mounting accessories.
The SAU upgrade keeps the compact extruded aluminum body but modernizes sensing to CMSG/DMSG/EMSG switches, whereas this older SU lacked a magnet entirely and cannot accept a sensor. Note that a plain cylinder drifts without live air; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X160 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 SAU50X160 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 SU50X160 Is Used
Package Diverting
Actuates diverting arms on packaging lines using the 982 N push force to redirect cartons reliably at 0.5 MPa.
Pallet Stopping
Functions as a compact end-stop for lightweight pallets, safely halting loads under the 50 kg vertical lift threshold.
Clamp Actuation
Secures medium workpieces during machining, utilizing the 825 N pull force to hold components firmly in jigs.
Replacing the Airtac SU32~50 Standard Cylinder SU50X160 with the SAU50X160
To replace this SU50X160, order the SAU50X160 direct equivalent, verifying your 1/4" port, M16x1.5 rod thread and SC-series mounting hardware. Because this specific SKU lacks a magnet (-S), it cannot support sensing; if position detection is needed, the SAU replacement requires CMSG/DMSG/EMSG switches. Size both ways: a 40mm bore yields 628 N push at 0.5 MPa, while a 63mm bore provides 1559 N. The 160mm stroke is standard, but always guide the rod to prevent side-load bending. For load holding on air loss, add a pilot-operated check valve or rod lock, as cushions only decelerate. The SAUF variant offers a built-in valve if faster cycling is needed.
Replacement checklist
- ✓ Same bore / stroke → SAU50X160
- ✓ 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 SU50X160 FAQ
Yes, the AirTAC SU50X160 is discontinued and end-of-life. The direct replacement is the SAU50X160. It shares the identical 50mm bore, 160mm stroke, 1/4" port, output force and SC-series mounting, so it fits the same application directly.
It 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. This SKU has no magnet and cannot take a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches.
