This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X40, 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 SU63-100 Standard Cylinder SU63X40
The AirTAC Airtac SU63-100 Standard Cylinder SU63X40 is a double-acting profile-type standard cylinder with a Ø63mm bore and 40mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X40, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X40
The AirTAC SU63X40 is a discontinued double-acting profile-type cylinder with a 63mm bore and 40mm stroke, delivering 1559N push force at 0.5MPa. AirTAC replaced this end-of-line unit with the SAU63X40, a direct upgrade retaining the exact 3/8 port, M16x1.5 rod thread, and SC-series mounting.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU successor adds a built-in valve option (SAUF) the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X40 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAU63X40 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 SU63-100 Standard Cylinder SU63X40 Is Used
Clamp Actuation
Provides 1559N of clamping thrust at 0.5MPa for securing heavy steel weldments during robotic welding operations.
Package Diverting
Drives a robust diverter arm on a high-speed packaging line, utilizing the 40mm stroke to redirect heavy cartons efficiently.
Pallet Stopping
Acts as a heavy-duty end-stop for loaded pallets on a gravity roller conveyor, safely absorbing kinetic energy via the adjustable cushion.
Replacing the Airtac SU63-100 Standard Cylinder SU63X40 with the SAU63X40
To replace this cylinder, order the SAU63X40 with the same 40mm stroke, 3/8 port, and PT/G/NPT thread. Since this non-magnetic SKU cannot hold a position switch, upgrade to an SAU63X40-S if you need sensing (note: SAU uses CMSG/DMSG/EMSG switches, not the legacy CS1-B/DS1-B). If 1559N at 0.5MPa is excessive, step down to a 50mm bore (982N); if you need more thrust, an 80mm bore yields 2513N. Remember, the air cushion only decelerates the piston near stroke end—it will not hold a load on air loss, so add an external rod lock for vertical safety. The SAUF variant integrates a 4M solenoid valve directly onto the body for faster cycling.
Replacement checklist
- ✓ Same bore / stroke → SAU63X40
- ✓ 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 SU63-100 Standard Cylinder SU63X40 FAQ
Yes, the AirTAC SU63X40 is discontinued. The direct replacement is the SAU63X40, which shares the identical 63mm bore, 40mm stroke, 3/8 port, output force, and SC-series mounting accessories.
This double-acting cylinder features a 3/8 inch air port. It delivers 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, 2805N push at 0.9MPa, and a maximum theoretical force of 318kgf at 1.0MPa.
