This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X270, 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 SU100X270 is a double-acting profile-type standard cylinder with a Ø100mm bore and 270mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X270, which matches its bore, stroke, force and mounting.
The AirTAC SU100X270 is a discontinued double-acting profile-type cylinder with a 100mm bore and 270mm stroke. Delivering 3927 N push force at 0.5 MPa, it uses an extruded aluminium barrel that is more compact than an ISO 15552 cylinder of the same size. AirTAC replaced this end-of-life unit with the SAU100X270 direct replacement, retaining the exact 1/2" port, M20x1.5 rod thread, output force, and SC-series mounting compatibility.
Because this specific SKU lacks a magnet (-S), it cannot accept a sensor. Additionally, the SAU upgrade introduces a built-in 4M solenoid valve option (SAUF) that the SU line never offered, while moving sensor compatibility to the current CMSG/DMSG/EMSG family for future sensing needs.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X270 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAU100X270 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| ×270 | 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.
Provides the robust 3927 N push force needed to eject dense metal stampings from a hydraulic press bed reliably.
Acts as a heavy-duty pneumatic stop gate on high-mass roller conveyors, securely halting loaded pallets.
Secures large injection mold halves, utilising the compact profile body to save floor space in tight cells.
To replace this discontinued SU100X270, order the SAU100X270 direct equivalent, confirming the 100mm bore, 270mm stroke, 1/2" port, and PT/G/NPT thread choice. Verify your SC-series mounting accessories (LB/FA/FB/CA/CB) fit the identical profile body. Since this SKU has no magnet, it cannot support a sensor; if sensing is required, order the SAU100X270-S and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. If you need integrated flow control, explore the SAUF valve-integrated variant. Sizing both ways: a neighbouring 80mm bore yields 2513 N push at 0.5 MPa, while a 100mm bore provides 5497 N at 0.7 MPa. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot-operated check valve for load holding. At 270mm stroke, ensure adequate guidance to prevent rod bending under side loads.
Replacement checklist
Yes, the SU100X270 is discontinued. The direct replacement is the SAU100X270. It features the same 100mm bore, 270mm stroke, 3927 N force, 1/2" port, and SC-series mounting accessories, fitting the exact same application.
It delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a theoretical max of 801 kgf at 1.0 MPa. A plain cylinder cannot hold a load without live air—the cushion only decelerates—so use an external rod lock or pilot-operated check valve for vertical holding.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU100X270 replacement — usually within 7-8 hours.
