This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X27, 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 SU100X27
The AirTAC SU63-100 Standard Cylinder SU100X27 is a double-acting profile-type standard cylinder with a Ø100mm bore and 27mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X27, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X27
The AirTAC SU100X27 is a discontinued double-acting profile-type cylinder featuring a 100mm bore and a 27mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 cylinder of the same size while sharing AirTAC SC-series mounting accessories. Delivering 3927 N of push force at 0.5 MPa, it uses a 1/2" port and a 25mm piston rod with M20x1.5 threading.
AirTAC replaced this end-of-life unit with the SAU100X27, a direct replacement matching the exact bore, stroke, output force, port size, and mounting footprint. This SKU lacks a magnet (-S) and therefore cannot accept a position sensor. For load holding, note that the adjustable 29mm air cushions only decelerate the piston near stroke ends; an external rod lock or pilot-operated check valve is required to prevent drift upon air loss.

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 SAU100X27 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 SU100X27 Is Used
Heavy-Duty Stamping
Ideal for short-stroke high-force pressing operations, delivering 5497 N at 0.7 MPa to seat bearings or form thick materials in automated machinery.
Pallet Stopper Gate
Functions as a robust 100mm bore blocking gate on heavy-load conveyor lines, using its 3927 N push force at 0.5 MPa to halt fully loaded pallets securely.
Industrial Clamp
Provides intense clamping pressure for large weldments or machining fixtures, utilizing the compact profile body to save space in dense manufacturing cells.
Replacing the Airtac SU63-100 Standard Cylinder SU100X27 with the SAU100X27
To replace the discontinued SU100X27, order the SAU100X27 direct equivalent, confirming the 100mm bore, 27mm stroke, 1/2" port, and default PT threads. Because this non-magnetic SKU cannot support a sensor, if detection is needed you must migrate to an SAU100X27-S and upgrade from the legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG family. The SAU platform also introduces the SAUF variant with a built-in 4M solenoid valve, offering self-switching functionality the SU line never had. If your application demands higher force, verify pressure limits, or if you need less thrust, step down to an 80mm bore providing 2513 N at 0.5 MPa. Since the 27mm stroke is very short, side-load and rod-bending risks are minimal, but always ensure rigid SC-series mounting to maintain alignment.
Replacement checklist
- ✓ Same bore / stroke → SAU100X27
- ✓ 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 SU100X27 FAQ
Yes, the SU100X27 is discontinued. The direct replacement is the AirTAC SAU100X27. It matches the original 100mm bore, 27mm stroke, 1/2" port, and SC-series mounting accessories perfectly, so no mechanical modifications are needed.
This double-acting cylinder delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a theoretical maximum of 801 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept a position sensor; the SAU-S replacement uses CMSG/DMSG/EMSG switches.
