This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAU63X270S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAU63X270S in place of this model. 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 SU63X270S
The AirTAC Airtac SU63-100 Standard Cylinder SU63X270S is a double-acting profile-type standard cylinder with a Ø63mm bore and 270mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAU63X270S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X270S
The AirTAC SU63X270S is a discontinued double-acting profile-type cylinder with a 63 mm bore and 270 mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 cylinder of the same bore while delivering 1559 N push force at 0.5 MPa. AirTAC replaced this end-of-life unit with the SAU63X270S, a true drop-in replacement retaining the exact 3/8" port, M16x1.5 rod thread, and SC-series mounting compatibility.
Because this SKU includes a magnet (-S), it originally used legacy CS1-B/DS1-B switches; upgrading to the SAU requires switching to current CMSG/DMSG/EMSG sensors. The SAU family also introduces a SAUF variant with a built-in 4M solenoid valve, an option the SU line never offered. For sizing, the safe working load is approximately 935 N (60% of the 0.5 MPa push force), translating to a vertical lift capacity of about 79 kg with a 2:1 safety margin. Note that 270 mm is a nonstandard stroke length.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X270S 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 SAU63X270S produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

| 63 | Bore size in mm. |
| ×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.
Where the Airtac SU63-100 Standard Cylinder SU63X270S Is Used
Package Diverting
Actuates routing gates on packaging lines, using the 1559 N thrust to push cartons firmly onto secondary tracks without rebound.
Pallet Stopping
Deploys a mechanical stop for 79 kg vertical-equivalent loads at roller conveyors, safely halting pallets for wrapping or inspection.
Press Ejection
Ejects formed parts from mid-sized presses, leveraging the compact profile body to fit within tight machine guarding while providing positive ejection.
Replacing the Airtac SU63-100 Standard Cylinder SU63X270S with the SAU63X270S
To replace the SU63X270S, order the SAU63X270S drop-in equivalent, verifying the 63 mm bore, 270 mm nonstandard stroke, 3/8" port (PT/G/NPT), and SC-series mounting hardware (LB/FA/FB/CA/CB). Because this is an -S model, you must account for the sensor family change: the legacy CS1-B/DS1-B switches are retired, so plan to install CMSG/DMSG/EMSG sensors on the SAU replacement. If your application requires integrated flow control, explore the SAUF variant which features a built-in 4M solenoid valve. For sizing alternatives, a 50 mm bore provides 982 N push at 0.5 MPa, while an 80 mm bore yields 2513 N. Remember that a standard cylinder drifts without live air—the cushion only decelerates—so use an external rod lock or pilot-operated check valve for secure load holding. At this 270 mm stroke, ensure adequate guidance to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same bore / stroke → SAU63X270S
- ✓ 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 SU63X270S FAQ
Yes, the SU63X270S is discontinued. The exact drop-in replacement is the AirTAC SAU63X270S. It matches the original 63 mm bore, 270 mm stroke, 3/8" port, output force, and SC-series mounting accessories exactly. You can swap it directly without modifying your machine.
At 0.5 MPa, it provides 1559 N push and 1402 N pull force, reaching 2182 N at 0.7 MPa and a theoretical maximum of 318 kgf at 1.0 MPa. Because this is an -S magnet model, it originally used CS1-B/DS1-B switches; the SAU replacement requires upgrading to CMSG/DMSG/EMSG sensors.
