This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU40X480, 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.

The AirTAC SU32~50 Standard Cylinder SU40X480 is a double-acting profile-type standard cylinder with a Ø40mm bore and 480mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU40X480, which matches its bore, stroke, force and mounting.
The AirTAC SU40X480 is a discontinued double-acting profile-type cylinder featuring a 40mm bore, 480mm stroke, and a 1/4" port. It delivers 628 N push force at 0.5 MPa. AirTAC replaced this legacy unit with the SAU40X480, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series mounting.
Because the 480mm stroke is relatively long, use an external guide to prevent rod bending under side loads. This non-magnetic SKU cannot accept a sensor. The SAU upgrade switches to CMSG/DMSG/EMSG switches and adds a SAUF built-in valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU40X480 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAU40X480 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 40 | Bore size in mm. |
| ×480 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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.
Drives a 480mm pusher arm to sort medium-weight packages along a packing line, utilizing the 628 N thrust at 0.5 MPa.
Ejects loaded pallets from a low-friction roller bed, requiring the full 480mm extension and external guides to prevent rod bending.
Extracts machined aluminum parts from a lathe chuck, safely operating within the 377 N working load limit at standard pressure.
To replace this discontinued SU40X480, order the SAU40X480. Confirm your 1/4" port, M12x1.25 rod thread, and SC-series mounting (LB/FA/FB/CA/CB) are compatible. If stepping up, the 50mm bore offers 982 N push at 0.5 MPa; stepping down to 32mm yields 402 N. This non-magnetic version cannot take a switch, but the SAU -S variant uses CMSG/DMSG/EMSG sensors. For the 480mm stroke, add external guides to prevent rod bending. Note: air cushions only decelerate; use a rod lock or pilot check valve to hold loads.
Replacement checklist
Yes, the SU40X480 is discontinued. The direct replacement is the AirTAC SAU40X480. It matches the 40mm bore, 480mm stroke, 1/4" port, and SC-series mounting, so no mechanical changes are needed.
At 0.5 MPa it provides 628 N push and 528 N pull; 879 N push at 0.7 MPa; 1130 N at 0.9 MPa; max 128 kgf at 1.0 MPa. This specific SKU lacks a magnet and cannot accept a sensor. The SAU replacement supports CMSG/DMSG/EMSG switches.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU40X480 replacement — usually within 7-8 hours.
