This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X90, 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 SU63X90
The AirTAC Airtac SU63-100 Standard Cylinder SU63X90 is a double-acting profile-type standard cylinder with a Ø63mm bore and 90mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X90, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X90
The AirTAC SU63X90 is a discontinued double-acting profile-type cylinder with a 63mm bore and 90mm stroke. It delivers 1559N push force at 0.5MPa through a 3/8" port. AirTAC replaced this legacy unit with the SAU63X90, a direct alternative retaining the exact bore, stroke, output force, port size, and SC-series mounting accessories.
Because this SKU lacks a magnet, it cannot accept a position switch. The SAU upgrade also adds the SAUF valve-integrated option the SU line never had. The extruded aluminum body is more compact than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X90 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 SAU63X90 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 SU63X90 Is Used
Clamp Actuation
Provides 1559N of push force at 0.5MPa to secure heavy workpieces in machining fixtures.
Package Diversion
Drives a 90mm stroke pop-up gate arm to route heavy cartons on a production line.
Pallet Stopping
Acts as a robust end-stop to halt loaded pallets accumulating at a transfer station.
Replacing the Airtac SU63-100 Standard Cylinder SU63X90 with the SAU63X90
To replace the SU63X90, order the SAU63X90 and verify your 3/8" port, M16x1.5 rod thread, and SC-series mounting hardware. Since this non-magnetic SKU has no sensor groove switch, you lose no legacy CS1-B/DS1-B wiring during the swap. If you need position detection on the new unit, the SAU uses current CMSG/DMSG/EMSG switches. For loads needing 2805N push at 0.9MPa, step up to an 80mm bore; for lighter 982N tasks, a 50mm bore suffices. A plain cylinder drifts on air loss—the 21mm cushions only decelerate—so add an external rod lock or pilot-operated check valve for strict load holding. The 90mm stroke is well under the 1500mm standard maximum, so rod bending is not a concern here.
Replacement checklist
- ✓ Same bore / stroke → SAU63X90
- ✓ 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 SU63X90 FAQ
Yes, the AirTAC SU63X90 is discontinued. The direct replacement is the SAU63X90, which matches the 63mm bore, 90mm stroke, 3/8" port, force, and SC-series mounting. You can install it directly into your existing setup.
It pushes 1559N and pulls 1402N at 0.5MPa, pushes 2182N at 0.7MPa, and reaches a theoretical max of 318kgf at 1.0MPa. The 21mm adjustable cushions only decelerate the piston near stroke ends; they do not hold loads on air loss, so use an external rod lock for holding.
