This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X550, 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 SU63X550
The AirTAC Airtac SU63-100 Standard Cylinder SU63X550 is a double-acting profile-type standard cylinder with a Ø63mm bore and 550mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X550, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X550
The AirTAC SU63X550 is a discontinued double-acting profile-type cylinder with a 63 mm bore and 550 mm stroke. It delivers 1559 N push and 1402 N pull at 0.5 MPa, making it a solid choice for medium-force automation. AirTAC replaced this end-of-life unit with the SAU63X550 direct replacement. It shares the exact bore, stroke, 3/8" port, and SC-series mounting, so it fits your existing setup without machining.
The extruded aluminum profile is more compact than an ISO 15552 cylinder. This non-magnet SKU cannot take a sensor; if you need position detection, the SAU upgrade supports CMSG/DMSG/EMSG switches (the SU used legacy CS1-B/DS1-B). The SAU line also adds a SAUF built-in-valve option the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X550 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 SAU63X550 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 SU63X550 Is Used
Pallet Diversion
Pushes heavy pallets onto auxiliary conveyor lines using 1559 N thrust at 0.5 MPa, with the 550 mm stroke clearing wide transfer beds.
Component Ejection
Ejects molded parts from heavy presses, using adjustable end cushions to safely stop the 63 mm piston at stroke limits.
Replacing the Airtac SU63-100 Standard Cylinder SU63X550 with the SAU63X550
To replace this discontinued SU63X550, order the SAU63X550. Confirm your 3/8" port, M16x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB) stay the same. Because this 550 mm stroke exceeds 300 mm, use an external guide to prevent rod bending and side-load wear. Sizing both ways: a 50 mm bore gives 982 N push at 0.5 MPa, while an 80 mm bore gives 2513 N. A plain cylinder drifts on air loss—the 21 mm cushions only decelerate; use a pilot-operated check valve or rod lock to hold loads. This no-magnet SKU cannot accept a switch.
Replacement checklist
- ✓ Same bore / stroke → SAU63X550
- ✓ 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 SU63X550 FAQ
Yes, the AirTAC SU63X550 is discontinued. The direct replacement is the SAU63X550. It matches the 63 mm bore, 550 mm stroke, 3/8" port, output force, and SC-series mounting. You can swap it directly without altering your machine.
It delivers 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a 318 kgf theoretical max at 1.0 MPa. This specific SKU lacks a magnet and cannot accept a sensor. The SAU replacement supports CMSG/DMSG/EMSG switches, whereas the SU used legacy CS1-B/DS1-B types.
