This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X35STC, 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 SU63X35STC
The AirTAC Airtac SU63-100 Standard Cylinder SU63X35STC is a double-acting profile-type standard cylinder with a Ø63mm bore and 35mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X35STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X35STC
The AirTAC SU63X35STC is a discontinued double-acting profile-type cylinder with a 63mm bore and 35mm stroke. It delivers 1559N push force at 0.5MPa via a 3/8" port. AirTAC replaced this legacy unit with the SAU63X35STC, a direct upgrade retaining the exact body dimensions, M16x1.5 rod thread, and SC-series TC mounting interface.
Because the original extruded aluminum barrel is shorter than an equivalent ISO 15552 cylinder, it saves machine space. Note that the SAU upgrade switches from legacy CS1-B/DS1-B switches to modern CMSG/DMSG/EMSG sensors, and introduces the SAUF built-in valve option the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X35STC 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 SAU63X35STC 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 SU63X35STC Is Used
Package Diverting
Ideal for short 35mm diverting strokes on packaging lines, utilizing the 1559N push force to push cartons cleanly at 0.5MPa.
Clamp Actuation
Provides reliable mid-force clamping for machining fixtures, where the compact profile body minimizes interference with moving tooling.
Replacing the Airtac SU63-100 Standard Cylinder SU63X35STC with the SAU63X35STC
To replace the SU63X35STC, order the SAU63X35STC ensuring your 3/8" port and M16x1.5 rod threads match. The TC mounting accessory is retained. If sizing alternatives, the adjacent 50mm bore yields 982N push at 0.5MPa, while the 80mm bore provides 2513N. A plain double-acting cylinder drifts without live air; the 21mm adjustable cushion only decelerates near stroke end, so use an external rod lock or pilot-operated check valve for held loads. The 35mm stroke is short enough to avoid rod-bending side-load issues. The SAU -S magnet uses CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B.
Replacement checklist
- ✓ Same bore / stroke → SAU63X35STC
- ✓ 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 SU63X35STC FAQ
Yes, the SU63X35STC is discontinued. The direct replacement is the AirTAC SAU63X35STC. It matches the 63mm bore, 35mm stroke, 1559N force, 3/8" port, and TC mounting. You simply order the SAU equivalent.
At 0.5MPa it pushes 1559N and pulls 1402N; at 0.7MPa it pushes 2182N, with a theoretical max of 318kgf at 1.0MPa. The SAU replacement retains the -S magnet but requires current CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B sensors.
