This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X225STC, 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 SU63X225STC
The AirTAC SU63-100 Standard Cylinder SU63X225STC 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 SAU63X225STC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X225STC
The AirTAC SU63X225STC is a discontinued double-acting profile cylinder with a 63mm bore, 225mm stroke, and a 3/8 inch port. Delivering 1559 N of push force at 0.5 MPa, it is directly replaced by the direct replacement SAU63X225STC, which matches the exact body, stroke, output force, and SC-series TC mounting interface.
The SAU upgrade introduces CMSG/DMSG/EMSG sensors to replace this unit's legacy CS1-B/DS1-B switches, and offers a new SAUF valve-integrated option. The extruded aluminum profile is more compact than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X225STC 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 SAU63X225STC 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 SU63X225STC Is Used
Package Diverting
Uses the 225mm stroke to push parcels smoothly across transfer belts, leveraging the 1559 N push force at 0.5 MPa for reliable mid-weight routing.
Pallet Stopper Gate
Acts as a pneumatic stop mechanism on low-profile roller conveyors where the compact extruded body avoids obstructing passing loads.
Replacing the Airtac SU63-100 Standard Cylinder SU63X225STC with the SAU63X225STC
To replace this discontinued SU63X225STC, order the SAU63X225STC with the identical 63mm bore, 225mm stroke, M16x1.5 rod thread, 3/8 inch port, and TC mounting. Because this model includes a magnet (-S), you must upgrade your sensors: the legacy CS1-B/DS1-B switches are replaced by the current CMSG/DMSG/EMSG family on the SAU. If you need a self-switching function, explore the SAUF variant which integrates a 4M solenoid valve directly on the body. When sizing, the 63mm bore yields 1559 N push and 1402 N pull at 0.5 MPa; if you need less force, a 50mm bore provides 982 N push, while an 80mm bore offers 2513 N. Note that a plain double-acting cylinder drifts if air pressure is lost, as the adjustable cushion only decelerates the piston near the stroke ends. For load holding on vertical applications, install an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAU63X225STC
- ✓ 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 SU63X225STC FAQ
Yes, the SU63X225STC is discontinued. The direct replacement is the SAU63X225STC, which shares the same 63mm bore, 225mm stroke, 3/8 inch port, and TC mounting. You will need to update your sensors, as the SAU uses CMSG/DMSG/EMSG switches instead of the older CS1-B/DS1-B.
This 63mm bore cylinder features a 3/8 inch port and delivers a push force of 1559 N and pull force of 1402 N at 0.5 MPa. At 0.7 MPa the push force is 2182 N, and the theoretical maximum is 318 kgf at 1.0 MPa. It operates at speeds of 30-800 mm/s.
