This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X140S, 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.

The AirTAC SU63-100 Standard Cylinder SU63X140S is a double-acting profile-type standard cylinder with a Ø63mm bore and 140mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X140S, which matches its bore, stroke, force and mounting.
The AirTAC SU63X140S is a discontinued double-acting profile cylinder with a 63mm bore and 140mm stroke. It delivers 1559N push and 1402N pull at 0.5MPa via a 3/8" port. AirTAC replaced this with the SAU63X140S, a direct upgrade retaining the exact body, force, and SC-series mounting.
The SAU replacement switches from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors, and introduces the SAUF built-in valve option. The cushion only decelerates; use a rod lock for holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X140S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAU63X140S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 63 | Bore size in mm. |
| ×140 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
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.
Uses the 1559N push force at 0.5MPa to reliably deflect heavy packaging along sorting lines.
Provides robust 140mm travel for securing medium-density workpieces during CNC machining.
Deploys the 79kg vertical-lift capacity to halt loaded pallets safely at staging zones.
To replace the SU63X140S, order the SAU63X140S, confirming the 3/8" port, M16x1.5 rod thread, and SC-series mounts. The -S magnet means you must upgrade sensors to CMSG/DMSG/EMSG. For loads needing holding on air loss, add an external rod lock. If 1559N at 0.5MPa is excessive, step down to a 50mm bore (982N); if pushing limits, an 80mm bore yields 2513N. The 140mm stroke is under the 1500mm max, avoiding rod-bending risks, but always guide side loads.
Replacement checklist
Yes, the SU63X140S is discontinued. The direct replacement is the SAU63X140S, matching the 63mm bore, 140mm stroke, 3/8" port, force, and SC-series mounting.
It pushes 1559N and pulls 1402N at 0.5MPa, pushes 2182N at 0.7MPa, and reaches a 318kgf max at 1.0MPa. The -S magnet used legacy CS1-B/DS1-B switches; the SAU replacement requires CMSG/DMSG/EMSG sensors.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU63X140S replacement — usually within 7-8 hours.
