This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X225, 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 SU63X225
The AirTAC Airtac SU63-100 Standard Cylinder SU63X225 is a double-acting profile-type standard cylinder with a Ø63mm bore and 225mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X225, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X225
The AirTAC SU63X225 is a discontinued double-acting profile cylinder with a 63 mm bore and 225 mm stroke. Delivering 1559 N push force at 0.5 MPa, it features an extruded aluminium barrel and adjustable air cushions at both ends. AirTAC replaced this end-of-life unit with the SAU63X225, a direct replacement retaining the exact 3/8" port, M16x1.5 rod thread, output force and SC-series mounting.
Because this specific SKU lacks a magnet, it cannot accept a position switch. The SAU upgrade introduces current CMSG/DMSG/EMSG sensors for its -S variants and a SAUF built-in 4M valve option the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X225 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 SAU63X225 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 SU63X225 Is Used
Package Diverting
Actuates divert arms on packaging lines using the 1559 N push force to redirect heavy cartons reliably at speed.
Pallet Stopper Gate
Raises and lowers stop gates for pallet accumulation, utilising the 225 mm stroke to clear tall unit loads.
Clamp Actuation
Secures medium workpieces in machining fixtures where the 318 kgf maximum force ensures rigid holding.
Replacing the Airtac SU63-100 Standard Cylinder SU63X225 with the SAU63X225
To replace this discontinued SU63X225, order the SAU63X225 direct equivalent, verifying the 225 mm stroke, 3/8" port, M16x1.5 rod thread and SC-series mounting hardware. Since this SKU has no -S magnet, it cannot support sensing; if you need position detection on the new unit, specify an SAU63X225S and migrate to CMSG/DMSG/EMSG switches. For loads needing hold on air loss, add an external rod lock or pilot-operated check valve, as cushions only decelerate. At 225 mm stroke side-load is minimal, but for strokes over 300 mm add guide rails to prevent rod bending. If you need less force, a 50 mm bore gives 982 N push at 0.5 MPa; for more power, an 80 mm bore yields 2513 N.
Replacement checklist
- ✓ Same bore / stroke → SAU63X225
- ✓ 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 SU63X225 FAQ
Yes, the AirTAC SU63X225 is discontinued. The direct replacement is the SAU63X225, which matches the 63 mm bore, 225 mm stroke, 3/8" port, force and SC-series mounting.
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. The cushions only decelerate; use an external rod lock to hold loads.
