This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X275, 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 SU63X275
The AirTAC SU63-100 Standard Cylinder SU63X275 is a double-acting profile-type standard cylinder with a Ø63mm bore and 275mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X275, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X275
The AirTAC SU63X275 is a discontinued double-acting profile-type cylinder with a 63 mm bore and 275 mm stroke. It delivers 1559 N push force at 0.5 MPa (2182 N at 0.7 MPa) and features an extruded aluminium barrel with adjustable air cushions at both ends, making it more compact than a standard ISO 15552 unit of the same bore. The direct replacement is the SAU63X275, matching the 3/8" port, M16x1.5 rod thread, output force, and SC-series mounting footprint.
When upgrading to the SAU63X275, note that the legacy CS1-B/DS1-B switches are replaced by current CMSG/DMSG/EMSG sensors, while the new SAUF variant offers a built-in 4M solenoid valve the SU line lacked. Because this specific SKU lacks a magnet (-S), it cannot accept any magnetic sensor.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X275 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 SAU63X275 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

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 SU63X275 Is Used
Package Diverting
Actuates diverter arms on packaging lines, using the 1559 N push force at 0.5 MPa to reliably redirect heavy cartons at speed.
Pallet Stopping
Deploys a mechanical stop block on roller conveyors to halt incoming pallets, absorbing kinetic energy via the 21 mm adjustable cushions.
Replacing the Airtac SU63-100 Standard Cylinder SU63X275 with the SAU63X275
To replace the discontinued SU63X275, order the SAU63X275 direct equivalent, confirming the 63 mm bore, 275 mm stroke, 3/8" port (default PT thread), and M16x1.5 rod-end thread. Verify your SC-series mounting accessories (LB/FA/FB/CA/CB) carry over directly. Since this SKU has no magnet, it cannot support sensing; if position detection is needed, specify the SAU63X275-S and migrate to CMSG/DMSG/EMSG switches. For loads requiring holding on air loss, add an external rod lock or pilot-operated check valve, as the adjustable cushion only decelerates. At 275 mm stroke, guide the load to prevent rod bending and side-load wear. If downsizing, a 50 mm bore yields 982 N push at 0.5 MPa; if upsizing, an 80 mm bore provides 2513 N.
Replacement checklist
- ✓ Same bore / stroke → SAU63X275
- ✓ 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 SU63X275 FAQ
Yes, the SU63X275 is discontinued. The direct replacement is the AirTAC SAU63X275. It shares the same 63 mm bore, 275 mm stroke, 318 kgf max force, 3/8" port, and SC-series mounting, so it fits the same application without mechanical modifications.
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 theoretical max of 318 kgf at 1.0 MPa. Because this specific SKU lacks a -S magnet, it cannot accept magnetic sensors; the SAU replacement with -S uses CMSG/DMSG/EMSG switches.
