This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X125TC, 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 SU63X125TC
The AirTAC SU63-100 Standard Cylinder SU63X125TC is a double-acting profile-type standard cylinder with a Ø63mm bore and 125mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X125TC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X125TC
The AirTAC SU63X125TC is a discontinued double-acting profile-type standard cylinder with a 63mm bore and 125mm stroke. It delivers 1559N push and 1402N pull at 0.5MPa, operating at 30-800mm/s through a 3/8" port. The direct replacement is the SAU63X125TC, matching the bore, stroke, force, port and TC mounting exactly.
Because it lacks a magnet, this SKU cannot accept a sensor. The SAU upgrade also uses modern CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B family, and introduces the SAUF built-in-valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X125TC 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 SAU63X125TC 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 SU63X125TC Is Used
Package Diversion
Actuates a TC-mounted routing gate on a packaging line, using the 1559N thrust at 0.5MPa to push cartons smoothly onto secondary tracks.
Clamp Actuation
Drives a mid-force clamping fixture in an assembly cell, relying on the 125mm stroke to position workpieces accurately.
Replacing the Airtac SU63-100 Standard Cylinder SU63X125TC with the SAU63X125TC
To replace this discontinued SU63X125TC, order the SAU63X125TC. Confirm the 3/8" port, M16x1.5 rod thread, PT thread type, and the SC-series TC mounting interface. Since this is a non-magnet SKU, it cannot take a sensor; if sensing is needed, an SAU with a magnet uses CMSG/DMSG/EMSG switches rather than the old CS1-B/DS1-B. Sizing both ways: a 50mm bore gives 982N push at 0.5MPa, while an 80mm bore gives 2513N. Note that a plain cylinder drifts without live air—the 21mm cushions only decelerate; use an external rod lock or pilot-operated check valve to hold loads. The SAUF variant integrates a 4M valve if faster response is needed.
Replacement checklist
- ✓ Same bore / stroke → SAU63X125TC
- ✓ 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 SU63X125TC FAQ
Yes, the SU63X125TC is discontinued. The direct replacement is the AirTAC SAU63X125TC. It provides the same 63mm bore, 125mm stroke, 3/8" port, output force, and TC mounting compatibility, fitting the exact same application.
It delivers 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, 2805N at 0.9MPa, and a max of 318kgf at 1.0MPa. It cannot hold a load without live air—the cushions only decelerate. Use an external rod lock or pilot-operated check valve for load holding.
