This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU50X150SFA, 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 SU50X150SFA
The AirTAC Airtac SU32~50 Standard Cylinder SU50X150SFA is a double-acting profile-type standard cylinder with a Ø50mm bore and 150mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU50X150SFA, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU50X150SFA
The AirTAC SU50X150SFA is a discontinued double-acting profile-type cylinder with a 50mm bore, 150mm stroke, 1/4" port, and FA mounting. Delivering 982N push force at 0.5MPa, it is superseded by the direct replacement SAU50X150SFA, which retains the same body dimensions, output, and SC-series mounting accessories.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors to replace this unit's legacy CS1-B/DS1-B switches, and offers a new SAUF valve-integrated variant. Note that the air cushion only decelerates the piston; it does not hold the load on air loss.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU50X150SFA 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 SAU50X150SFA 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 SU50X150SFA Is Used
Clamping Mechanisms
Provides 982N of push force at 0.5MPa to securely hold medium-density workpieces during machining or assembly operations.
Package Diverting
Actuates routing gates on 50mm bore pneumatic lines, utilizing the 150mm stroke to redirect products efficiently.
Replacing the Airtac SU32~50 Standard Cylinder SU50X150SFA with the SAU50X150SFA
To replace the SU50X150SFA, order the SAU50X150SFA, confirming the 50mm bore, 150mm stroke, M16x1.5 rod thread, 1/4" port (PT/G/NPT), and FA mounting. Because this SKU includes the -S magnet, you must upgrade your switches from the old CS1-B/DS1-B to the SAU-compatible CMSG/DMSG/EMSG family. Sizing alternatives: a 40mm bore yields 628N push at 0.5MPa, while a 63mm bore provides 1559N. For any load holding, add an external rod lock or pilot-operated check valve, as standard air cushions only decelerate. At 150mm stroke, side-load risk is low, but ensure correct rod alignment to prevent premature seal wear. If self-switching is needed, consider the SAUF variant with its built-in 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU50X150SFA
- ✓ 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 SU50X150SFA FAQ
Yes, the AirTAC SU50X150SFA is discontinued. The direct replacement is the SAU50X150SFA. It shares the identical 50mm bore, 150mm stroke, 1/4" port, output force, and SC-series FA mounting, so it fits the same application directly.
This 50mm bore cylinder delivers 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, and a theoretical max of 200kgf at 1.0MPa. Because this model has the -S magnet, it used legacy CS1-B/DS1-B switches; the SAU replacement requires upgrading to CMSG/DMSG/EMSG sensors.
