This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X110STC, 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 SU63X110STC
The AirTAC SU63-100 Standard Cylinder SU63X110STC is a double-acting profile-type standard cylinder with a Ø63mm bore and 110mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X110STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X110STC
The AirTAC SU63X110STC is a discontinued double-acting profile-type cylinder featuring a 63 mm bore, 110 mm stroke, and a 3/8" port. It delivers 1559 N push force at 0.5 MPa. AirTAC replaced this unit with the SAU63X110STC, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series TC mounting interface.
The SAU replacement introduces modern CMSG/DMSG/EMSG sensors, superseding the legacy CS1-B/DS1-B switches used on this -S SKU, and adds an optional SAUF built-in 4M valve. Note that the air cushion only decelerates the load; an external rod lock is required to hold position.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X110STC 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 SAU63X110STC 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 SU63X110STC Is Used
Package Diversion
Pushes medium-weight cartons off a sorting line using 1559 N of thrust at 0.5 MPa, with TC mounting allowing rigid top-plate fixation.
Pallet Stopper
Halts incoming pallets on a roller conveyor, using the adjustable 21 mm air cushions to decelerate the load smoothly at stroke ends.
Replacing the Airtac SU63-100 Standard Cylinder SU63X110STC with the SAU63X110STC
To replace this discontinued SU63X110STC, order the SAU63X110STC. Confirm the 3/8" port, M16x1.5 rod thread, and the TC mounting accessory are retained. Because this unit has an -S magnet, you must migrate from the old CS1-B/DS1-B switches to the current CMSG/DMSG/EMSG sensor family. If you need self-switching, the SAU family offers the SAUF variant with a built-in valve. For sizing, stepping down to a 50 mm bore yields 982 N push at 0.5 MPa, while stepping up to an 80 mm bore provides 2513 N. Remember, a plain cylinder drifts without live air; use a pilot-operated check valve or external rod lock for load holding. At 110 mm stroke, rod bending is minimal, but always guide the load to prevent side-loading.
Replacement checklist
- ✓ Same bore / stroke → SAU63X110STC
- ✓ 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 SU63X110STC FAQ
Yes, the AirTAC SU63X110STC is discontinued. The direct replacement is the SAU63X110STC. It shares the same 63 mm bore, 110 mm stroke, 3/8" port, output force, and SC-series TC mounting, so it fits the same application directly.
It provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a theoretical max of 318 kgf at 1.0 MPa. Because this SKU includes a magnet (-S), it used legacy CS1-B/DS1-B switches; the SAU replacement requires upgrading to CMSG/DMSG/EMSG sensors.
