This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU32X135, 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 SU32X135
The AirTAC Airtac SU32~50 Standard Cylinder SU32X135 is a double-acting profile-type standard cylinder with a Ø32mm bore and 135mm stroke, 1/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU32X135, which matches its bore, stroke, force and mounting.

About the Airtac SU32~50 Standard Cylinder SU32X135
The AirTAC SU32X135 is a discontinued double-acting profile-type cylinder featuring a 32mm bore and a 135mm nonstandard stroke. It delivers 402N push and 345N pull at 0.5MPa via a 1/8" port. The direct replacement is the SAU32X135, preserving the original bore, stroke, output force, and SC-series mounting footprint.
Because this legacy SKU lacks a magnet, it cannot accept a sensor. If sensing is required, the SAU upgrade supports modern CMSG/DMSG/EMSG switches, whereas the older SU line used CS1-B/DS1-B. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU32X135 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 SAU32X135 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SU32~50 Standard Cylinder SU32X135 Is Used
Small Part Ejection
Uses the 402N push force at 0.5MPa to eject small molded components from a fixture, with the 135mm stroke providing adequate clearance for robotic pickup.
Package Diverting
Actuates a lightweight diverter arm on a packaging line, where the compact profile body saves space and the 1/8 inch port delivers sufficient flow for rapid cycling.
Clamp Actuation
Secures small workpieces during light machining, relying on the 345N pull force at 0.5MPa to hold the part firmly against the stop.
Replacing the Airtac SU32~50 Standard Cylinder SU32X135 with the SAU32X135
To replace this discontinued SU32X135, order the SAU32X135, ensuring you keep the 1/8" port, M10x1.25 rod thread, and SC-series mounting. Since the 135mm stroke is nonstandard, verify lead times. This base SKU has no magnet, so it cannot hold a switch; if you need position sensing, specify an SAU model with an -S option and use CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. For higher loads, consider the 40mm bore (628N push at 0.5MPa); for lighter duty, the 32mm bore is adequate. Remember, the 21mm air cushions only decelerate the piston near stroke end and do not hold a load on air loss—install an external rod lock or pilot-operated check valve for vertical holding. At 135mm stroke, side-load and rod-bending risks are low, but ensure correct alignment to prevent seal wear.
Replacement checklist
- ✓ Same bore / stroke → SAU32X135
- ✓ 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 SU32X135 FAQ
Yes, the AirTAC SU32X135 is discontinued. The direct replacement is the SAU32X135. It offers the same 32mm bore, 135mm stroke, 402N force at 0.5MPa, 1/8" port, and SC-series mounting compatibility, so it fits the same application directly.
The 32mm bore generates 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, and a theoretical max of 82kgf at 1.0MPa. This specific SKU has no magnet, meaning it cannot accept a sensor. The SAU replacement supports CMSG/DMSG/EMSG switches if sensing is needed.
