This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X1050S, 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 SU100X1050S
The AirTAC SU63-100 Standard Cylinder SU100X1050S is a double-acting profile-type standard cylinder with a Ø100mm bore and 1050mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X1050S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X1050S
The AirTAC SU100X1050S is a discontinued double-acting profile-type cylinder with a 100 mm bore and 1050 mm stroke. Built with an extruded aluminum barrel, it delivers 3927 N push force at 0.5 MPa and features a 1/2" port. The direct replacement is the SAU100X1050S, matching the bore, stroke, output, port, and SC-series mounting.
When upgrading to the SAU100X1050S, the piston magnet shifts from legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensor family. The SAU line also introduces a SAUF variant with a built-in 4M solenoid valve, an option the SU never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X1050S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAU100X1050S 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 SU100X1050S Is Used
Heavy Stamping Press
Drives heavy tooling dies with 3927 N push force at 0.5 MPa, utilizing adjustable 29 mm cushions to absorb impact at stroke ends.
Pallet Transfer Line
Moves large automated pallets over a 1050 mm span, requiring external guide rails to prevent rod bending during lateral motion.
Replacing the Airtac SU63-100 Standard Cylinder SU100X1050S with the SAU100X1050S
To replace this SU with the SAU100X1050S, verify the 100 mm bore, 1050 mm stroke, 1/2" port, M20x1.5 rod thread, and SC-series mounting. Because this is a nonstandard stroke exceeding the 1000 mm typical max for smaller bores, ensure external guides are used to prevent rod bending over the 1050 mm extension. If sizing neighbors, a 80 mm bore yields 2513 N push at 0.5 MPa, while this 100 mm bore provides 3927 N. Note that a plain cylinder drifts without live air; use an external rod lock or pilot-operated check valve for held loads. The -S magnet requires switching to CMSG/DMSG/EMSG sensors on the new SAU, or explore the SAUF valve-integrated variant.
Replacement checklist
- ✓ Same bore / stroke → SAU100X1050S
- ✓ 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 SU100X1050S FAQ
Yes, the SU100X1050S is discontinued. The direct replacement is the AirTAC SAU100X1050S, which shares the identical 100 mm bore, 1050 mm stroke, 1/2" port, output force, and SC-series mounting accessories.
It delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a maximum theoretical force of 801 kgf at 1.0 MPa. The -S magnet on this SU worked with legacy CS1-B/DS1-B switches; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
