This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUD40X1000, 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 SUD Series Double Rod Cylinder SUD40X1000
The AirTAC Airtac SUD Series Double Rod Cylinder SUD40X1000 is a double-acting profile-type standard cylinder with a Ø40mm bore and 1000mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUD40X1000, which matches its bore, stroke, force and mounting.

About the Airtac SUD Series Double Rod Cylinder SUD40X1000
The AirTAC SUD40X1000 is a double-acting, double-rod profile cylinder featuring a 40mm bore and 1000mm stroke. A piston rod exits both ends, meaning push and pull forces are equal both ways at 528N @0.5MPa, 739N @0.7MPa, and 950N @0.9MPa. This discontinued model uses an extruded aluminum barrel and a 1/4" port. The direct replacement is the SAUD40X1000, matching the bore, stroke, force, and FA/LB mounting.
Because the rod exits both ends, the back rod can drive a second tool or act as an anti-rotation guide. This non-magnetic SKU cannot take a sensor. Note that air cushions only decelerate the piston near stroke end; they do not hold loads on air loss, requiring an external rod lock for holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUD40X1000 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAUD40X1000 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 SUD Series Double Rod Cylinder SUD40X1000 Is Used
Dual-Tool Drive Station
Uses the rod protruding from both ends to push a part on the front while simultaneously actuating a secondary clamp on the back.
Anti-Rotation Transfer
The double-rod construction prevents piston rotation during long 1000mm transfers, ensuring precise alignment for downstream handling.
Symmetric Push-Pull Gate
Equal both-ways force allows the cylinder to reliably open and close heavy diverter gates without needing a larger bore for the pull stroke.
Replacing the Airtac SUD Series Double Rod Cylinder SUD40X1000 with the SAUD40X1000
To replace the discontinued SUD40X1000, order the direct replacement SAUD40X1000, which shares the exact 40mm bore, 1000mm stroke, 1/4" port, and FA/LB mounting. When sizing both ways, verify the equal both-ways force fits your application, checking neighboring bores if extra margin is needed. A double rod is right when you need anti-rotation resistance or dual tool driving. Because this SKU lacks a magnet (-S), it cannot take sensors, whereas the SAUD upgrades to CMSG/DMSG/EMSG sensors (this legacy used CS1-B/DS1-B). Finally, at 1000mm stroke, account for side-load and rod-bending by adding external guides to prevent premature wear.
Replacement checklist
- ✓ Same bore / stroke → SAUD40X1000
- ✓ 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 SUD Series Double Rod Cylinder SUD40X1000 FAQ
Yes, the SUD40X1000 is discontinued. The direct replacement is the SAUD40X1000, which matches the 40mm bore, 1000mm stroke, equal force, 1/4" port, and FA/LB mounting.
The SUD40X1000 provides equal both-ways force of 528N @0.5MPa, 739N @0.7MPa, and 950N @0.9MPa. It uses a 1/4" port, features a 16mm rod, and operates at speeds of 30-800 mm/s.
