This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X205, 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 SU63X205
The AirTAC Airtac SU63-100 Standard Cylinder SU63X205 is a double-acting profile-type standard cylinder with a Ø63mm bore and 205mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X205, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X205
The AirTAC SU63X205 is a discontinued double-acting profile-type cylinder with a 63 mm bore and 205 mm stroke. Delivering 1559 N push force at 0.5 MPa, it features an extruded aluminium barrel and adjustable air cushions, making it shorter than an ISO 15552 cylinder of the same bore. AirTAC replaced this end-of-life unit with the SAU63X205, a direct replacement retaining the exact 3/8" port, M16x1.5 rod thread and SC-series mounting.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors and a new SAUF built-in-valve option the SU line lacked. For this non-magnetic SKU, sensing is not possible. Note that standard air cushions only decelerate the piston; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X205 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 SAU63X205 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 SU63X205 Is Used
Package Diverting
Actuates routing gates on 3/8" ported conveyors, using the 1559 N thrust to push 79 kg cartons smoothly with adjustable end cushions.
Pallet Stopping
Deploys a 205 mm stroke stop block in low-profile distribution hubs, handling pallet inertia safely within the 935 N working load limit.
Clamp Actuation
Secures medium-duty aluminium extrusions for machining, leveraging the compact profile body to fit tight cell footprints without tie-rod obstructions.
Replacing the Airtac SU63-100 Standard Cylinder SU63X205 with the SAU63X205
To replace the SU63X205, order the SAU63X205 direct equivalent, verifying your 3/8" port, M16x1.5 thread, PT/G/NPT fitting choice and SC-series mounting (LB/FA/FB/CA/CB). This non-magnetic SKU cannot accept a sensor; if position detection is needed, specify an SAU63X205-S and migrate to CMSG/DMSG/EMSG switches, as the SU used legacy CS1-B/DS1-B units. Sizing both ways: a 50 mm bore gives 982 N push at 0.5 MPa, while an 80 mm bore yields 2513 N. For load holding on air loss, add a pilot-operated check valve or rod lock, as cushions only decelerate. At 205 mm stroke, rod bending stress is low, but ensure adequate guide support to prevent side-load wear.
Replacement checklist
- ✓ Same bore / stroke → SAU63X205
- ✓ 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 SU63X205 FAQ
Yes, the SU63X205 is discontinued. The direct replacement is the AirTAC SAU63X205. It shares the identical 63 mm bore, 205 mm stroke, 1559 N output force, 3/8" port and SC-series mounting, so it fits the same application directly.
At 0.5 MPa it provides 1559 N push and 1402 N pull; at 0.7 MPa it pushes 2182 N, with a theoretical max of 318 kgf at 1.0 MPa. This specific SKU lacks a magnet, so it cannot take a sensor; the SAU-S variant uses CMSG/DMSG/EMSG switches.
