This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X140TC, 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 SU80X140TC is a double-acting profile-type standard cylinder with a Ø80mm bore and 140mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X140TC, which matches its bore, stroke, force and mounting.
The AirTAC SU80X140TC is a discontinued double-acting profile-type cylinder with an 80 mm bore and 140 mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 cylinder of the same bore and delivers 2513 N push force at 0.5 MPa. The direct replacement is the SAU80X140TC, matching the 3/8" port, M20x1.5 rod thread, 28 mm cushions, and SC-series TC mounting.
Because this SKU lacks a magnet (-S), it cannot accept a sensor. If sensing is needed, the SAU replacement uses modern CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. Note that a plain cylinder drifts without live air; use an external rod lock for holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X140TC carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X140TC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| ×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.
Handles heavy pallet routing on packaging lines using the 2513 N push force at 0.5 MPa, leveraging the TC mount for stable trunnion pivoting.
Ejects formed metal parts from a press using the 28 mm adjustable end cushions to decelerate the 80 mm bore smoothly over the 140 mm travel.
To replace this discontinued SU80X140TC, order the SAU80X140TC. It is a direct: matching the 80 mm bore, 140 mm stroke, 3/8" port, and TC mounting interface. Verify your thread standard (PT, G, or NPT) when ordering. Since this specific SKU has no magnet, it cannot support sensing; if you need position detection, specify an SAU80X140TC-S and migrate to CMSG/DMSG/EMSG switches. For force context, the 80 mm bore yields 2513 N push at 0.5 MPa; stepping down to a 63 mm bore drops push to 1559 N, while an 80 mm at 0.7 MPa yields 3518 N. Remember that the air cushions only decelerate the load near stroke end; a plain cylinder does not hold position on air loss, so add a pilot-operated check valve or rod lock for vertical holding.
Replacement checklist
Yes, the SU80X140TC is discontinued. The direct replacement is the SAU80X140TC. It shares the exact same 80 mm bore, 140 mm stroke, 513 kgf max force, 3/8" port, and SC-series TC mounting, fitting directly into your existing application.
The 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a 513 kgf max at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept a sensor; the SAU-S replacement uses CMSG/DMSG/EMSG switches.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU80X140TC replacement — usually within 7-8 hours.
