This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X280, 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 SU63X280
The AirTAC Airtac SU63-100 Standard Cylinder SU63X280 is a double-acting profile-type standard cylinder with a Ø63mm bore and 280mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X280, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X280
The AirTAC SU63X280 is a discontinued double-acting profile-type cylinder with a 63 mm bore and 280 mm stroke. It delivers 1559 N push and 1402 N pull at 0.5 MPa, peaking at a theoretical 318 kgf. The direct replacement is the SAU63X280, retaining the identical extruded aluminium body, 3/8" port, M16x1.5 rod thread and SC-series mounting.
This compact profile body is shorter than a same-bore ISO 15552 unit. Since this SKU lacks a magnet, it cannot accept a sensor. The SAU upgrade switches to CMSG/DMSG/EMSG switches and adds a SAUF valve-integrated option the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X280 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 SAU63X280 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 SU63X280 Is Used
Carton Diverting
Pushes packages at 30-800 mm/s on packaging lines, using the 1559 N thrust at 0.5 MPa to redirect heavy goods without rebound.
Pallet Stops
Acts as a robust 63 mm bore end-stop for roller conveyors, absorbing kinetic energy via the 21 mm adjustable air cushions at both ends.
Clamp Actuation
Secures workpieces during machining, providing a firm 1402 N pull force at 0.5 MPa within a compact profile body footprint.
Replacing the Airtac SU63-100 Standard Cylinder SU63X280 with the SAU63X280
To replace this SU63X280, order the SAU63X280 with the same 63 mm bore, 280 mm stroke, 3/8" port and PT/G/NPT thread. Reuse your existing SC-series mounts. If sizing neighbours, a 50 mm bore yields 982 N push at 0.5 MPa, while an 80 mm bore gives 2513 N. Because this non-magnet SKU cannot take a switch, sensing requires external proximity targets. For any stroke over 300 mm, guide the load to prevent rod bending. Note that the cushion only decelerates; use a rod lock or pilot check valve to hold loads.
Replacement checklist
- ✓ Same bore / stroke → SAU63X280
- ✓ 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 SU63X280 FAQ
Yes, the SU63X280 is discontinued. The direct replacement is the AirTAC SAU63X280. It matches the 63 mm bore, 280 mm stroke, 318 kgf max force, 3/8" port and SC-series mounting, so it fits the same application directly.
It pushes 1559 N and pulls 1402 N at 0.5 MPa, pushes 2182 N at 0.7 MPa, and reaches a 318 kgf max at 1.0 MPa. The cylinder does not hold load on air loss; the cushions only decelerate. For load holding, install an external rod lock or pilot-operated check valve.
