This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X840S, 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 SU100X840S
The AirTAC SU63-100 Standard Cylinder SU100X840S is a double-acting profile-type standard cylinder with a Ø100mm bore and 840mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X840S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X840S
The AirTAC SU100X840S is a discontinued double-acting profile-type cylinder with an 840 mm stroke and 100 mm bore. It delivers 3927 N push force at 0.5 MPa through a 1/2 inch port. AirTAC replaced this unit with the SAU100X840S, a direct upgrade retaining the exact body dimensions, stroke, output force, and SC-series mounting hardware.
The SAU upgrade introduces current CMSG, DMSG and EMSG sensors, replacing the legacy CS1-B and DS1-B switches used on this -S magnet model. The SAU family also adds a SAUF variant with a built-in 4M solenoid valve.

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 SAU100X840S 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 SU100X840S Is Used
Heavy Material Transfer
Drives large pallets or heavy assemblies along extended conveyor sections, utilizing the 840 mm stroke and 3927 N push force at 0.5 MPa to move substantial loads across workstation gaps.
Elevated Storage Pusher
Actuates long-travel pushing arms in automated high-bay warehousing, relying on the 100 mm bore to dispatch heavy totes from roller lanes into sorting channels.
Large Assembly Press
Executes long linear positioning and pressing of heavy industrial components, taking advantage of the 840 mm travel to lower large machinery housings onto base fixtures.
Replacing the Airtac SU63-100 Standard Cylinder SU100X840S with the SAU100X840S
To replace this discontinued SU100X840S, order the SAU100X840S direct equivalent, verifying the 100 mm bore, 840 mm stroke, 1/2 inch port, M20x1.5 rod thread, and SC-series mounting. Because the -S magnet is present, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG on the new unit. For the 840 mm stroke, use an external guide to prevent rod bending and side-load damage. This cylinder does not hold load without live air; use an external rod lock or pilot-operated check valve for holding. If you need a smaller bore, the 80 mm yields 2513 N push at 0.5 MPa; if larger force is needed, this 100 mm bore provides 5497 N at 0.7 MPa. The SAUF valve-integrated option is available if you need self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU100X840S
- ✓ 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 SU100X840S FAQ
Yes, the SU100X840S is discontinued. The direct replacement is the AirTAC SAU100X840S. It matches the 100 mm bore, 840 mm stroke, 1/2 inch port, output force, and SC-series mounting accessories, so it fits the same application directly.
The 100 mm bore provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a theoretical max of 801 kgf at 1.0 MPa. Because this is an -S magnet model, it used legacy CS1-B and DS1-B switches; the SAU replacement requires the current CMSG, DMSG, or EMSG sensor family.
