This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X340STC, 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 SU100X340STC
The AirTAC SU63-100 Standard Cylinder SU100X340STC is a double-acting profile-type standard cylinder with a Ø100mm bore and 340mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X340STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X340STC
The AirTAC SU100X340STC is a discontinued double-acting profile-type cylinder with a 100mm bore and 340mm stroke. It delivers 3927 N push force at 0.5 MPa through a 25mm rod and 1/2" port. AirTAC replaced this unit with the SAU100X340STC, a direct upgrade retaining the exact body dimensions, force output, and SC-series TC mounting interface.
The SAU replacement modernizes the sensor groove, moving from the legacy CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG family. It also introduces the SAUF variant with a built-in 4M solenoid valve, an option the original SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X340STC 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 SAU100X340STC 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 SU100X340STC Is Used
Heavy Press Clamping
Secures large metal castings during machining operations, utilizing the 3927 N push force at 0.5 MPa to prevent workpiece shifting under high spindle loads.
Pallet Reject Arm
Actuates a 340mm swing arm to push overweight pallets off the main conveyor line, safely handling loads up to the 200 kg vertical lift threshold.
Industrial Door Actuation
Drives the opening and closing of heavy acoustic machinery enclosure doors, relying on the TC mount and 25mm rod to manage lateral inertia.
Replacing the Airtac SU63-100 Standard Cylinder SU100X340STC with the SAU100X340STC
To replace the SU100X340STC, order the SAU100X340STC. Verify your 1/2" port thread (PT, G, or NPT), the M20x1.5 rod-end, and the TC mounting accessory. Because this SKU includes a magnet (-S), note that your old CS1-B/DS1-B switches will not fit the SAU; you must upgrade to CMSG/DMSG/EMSG sensors. If sizing alternatives, a neighbouring 80mm bore yields 2513 N push at 0.5 MPa, while stepping up to 0.7 MPa on this 100mm bore provides 5497 N. At 340mm stroke, add external guides to prevent rod bending and side-load wear. This cylinder will not hold a load without live air; the 29mm cushions only decelerate, so add an external rod lock or pilot-operated check valve for vertical holding.
Replacement checklist
- ✓ Same bore / stroke → SAU100X340STC
- ✓ 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 SU100X340STC FAQ
Yes, the SU100X340STC is discontinued. The direct replacement is the SAU100X340STC. It matches the 100mm bore, 340mm stroke, 1/2" port, and TC mounting dimensions perfectly, while offering the same 801 kgf maximum theoretical force.
At 0.5 MPa it provides 3927 N push and 3681 N pull; at 0.7 MPa it pushes 5497 N, and 7068 N at 0.9 MPa, with an 801 kgf max at 1.0 MPa. Because this model has a magnet (-S), note the SAU replacement requires CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B sensors.
