This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X250TC, 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 SU80X250TC is a double-acting profile-type standard cylinder with a Ø80mm bore and 250mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X250TC, which matches its bore, stroke, force and mounting.
The AirTAC SU80X250TC is a discontinued double-acting profile cylinder featuring an 80mm bore and 250mm stroke. Delivering 2513 N push force at 0.5 MPa, it uses an extruded aluminum barrel with a 3/8" port and M20x1.5 rod thread. AirTAC replaced this unit with the SAU80X250TC, a direct replacement retaining the exact bore, stroke, output force, port size and TC mounting interface.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU upgrade also transitions to current CMSG/DMSG/EMSG switches if you later need sensing, and introduces the SAUF built-in valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X250TC 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 SAU80X250TC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| ×250 | 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 TC mount to clear the belt frame while providing 2513 N of push force.
Pushes loaded shipping cartons from sorting tables where the 250mm stroke and 128 kg safe vertical lift capacity manage substantial weights.
Ejects formed metal components from press beds, utilizing the 28mm adjustable cushion to decelerate the 80mm bore at stroke end.
To replace this discontinued SU80X250TC, order the SAU80X250TC ensuring your 3/8" port, M20x1.5 thread and TC mounting match. This non-magnetic SKU cannot take a switch, but if sensing is added on the SAU, use CMSG/DMSG/EMSG sensors instead of legacy CS1-B/DS1-B. For loads needing holding on air loss, add an external rod lock or pilot-operated check valve, as cushions only decelerate. At 250mm stroke, guide the load to prevent rod bending. If downsizing, a 63mm bore gives 1559 N push; if upsizing, a 100mm bore yields 3927 N.
Replacement checklist
Yes, the SU80X250TC is discontinued. The direct replacement is the SAU80X250TC. It shares the same 80mm bore, 250mm stroke, 3/8" port, force and TC mounting, so it drops into the exact same application.
It delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a max of 513 kgf at 1.0 MPa. This specific SKU has no magnet, so it cannot take a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU80X250TC replacement — usually within 7-8 hours.
