This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X250TC, 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 SU63X250TC
The AirTAC SU63-100 Standard Cylinder SU63X250TC is a double-acting profile-type standard cylinder with a Ø63mm bore and 250mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X250TC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X250TC
The AirTAC SU63X250TC is a discontinued double-acting profile-type cylinder with a 63 mm bore and 250 mm stroke. It delivers 1559 N push force at 0.5 MPa via a 3/8" port. AirTAC replaced this unit with the SAU63X250TC, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series TC mounting interface.
Because this SKU lacks a magnet, it cannot accept a sensor. The SAU upgrade uses modern CMSG/DMSG/EMSG switches on its -S variants, and introduces the SAUF built-in-valve option the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X250TC 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 SAU63X250TC 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.
Where the Airtac SU63-100 Standard Cylinder SU63X250TC Is Used
Conveyor Diverter
Pushes heavy cartons off a main packaging line using 1559 N of thrust at 0.5 MPa, with the TC mount allowing rigid trunnion attachment to the conveyor frame.
Pallet Stop Gate
Acts as a robust pneumatic stop for incoming pallets, safely absorbing kinetic energy via the 21 mm adjustable air cushions at both stroke ends.
Clamp Actuator
Secures heavy metal workpieces during machining, delivering up to 318 kgf maximum holding thrust at 1.0 MPa operating pressure.
Replacing the Airtac SU63-100 Standard Cylinder SU63X250TC with the SAU63X250TC
To replace this discontinued SU63X250TC, order the SAU63X250TC. Verify your 3/8" port, M16x1.5 rod thread, and TC mounting accessory. Since this specific SKU has no magnet (-S), it cannot support sensing; if you need position detection on the new unit, specify an SAU63X250TC-S and switch to CMSG/DMSG/EMSG sensors. If sizing alternatives, a 50 mm bore yields 982 N push at 0.5 MPa, while an 80 mm bore provides 2513 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so fit an external rod lock for held loads. At 250 mm stroke, guide the load to prevent rod bending.
Replacement checklist
- ✓ Same bore / stroke → SAU63X250TC
- ✓ 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 SU63X250TC FAQ
Yes, the AirTAC SU63X250TC is discontinued and end-of-life. The direct replacement is the SAU63X250TC. It shares the identical 63 mm bore, 250 mm stroke, 3/8" port, output force, and SC-series TC mounting, so it fits the same application without modification.
This double-acting cylinder delivers 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a maximum theoretical force of 318 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches on its -S variants.
