This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X245S, 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 SU63X245S
The AirTAC SU63-100 Standard Cylinder SU63X245S is a double-acting profile-type standard cylinder with a Ø63mm bore and 245mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X245S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X245S
The AirTAC SU63X245S is a discontinued double-acting profile cylinder with a 63mm bore and 245mm stroke. It delivers 1559N push and 1402N pull at 0.5MPa. AirTAC replaced it with the SAU63X245S, a direct upgrade retaining the exact bore, stroke, 3/8" port, M16x1.5 rod thread and SC-series mounting.
This extruded aluminium profile is shorter than an ISO 15552 equivalent. The -S magnet on this legacy unit worked with CS1-B/DS1-B switches, but the SAU replacement uses current CMSG/DMSG/EMSG sensors. Note that a plain cylinder drifts without live air; use a rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X245S 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 SAU63X245S 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 SU63X245S Is Used
Package Diverting
Actuates routing gates on packaging lines where the 1559N push force at 0.5MPa easily overcomes carton friction.
Vertical Pressing
Provides a safe 935N working load for pressing lightweight bearings, with the 245mm stroke allowing deep reach.
Pallet Stops
Deploys heavy-duty end stops on roller conveyors, utilising the compact 63mm profile body to save space.
Replacing the Airtac SU63-100 Standard Cylinder SU63X245S with the SAU63X245S
To replace the SU63X245S, order the SAU63X245S. Confirm your 3/8" port, M16x1.5 thread, PT/G/NPT option and SC-series mounts (LB/FA/FB/CA/CB/TC) as they are unchanged. The -S magnet means you must upgrade sensors from legacy CS1-B/DS1-B to CMSG/DMSG/EMSG. If you need higher force, the 80mm bore offers 2513N push at 0.5MPa; if lower, the 50mm bore gives 982N. The 245mm stroke is under the 1500mm standard limit, so no side-load guide is mandatory, but always prevent rod bending. The cushion only decelerates; it does not hold load on air loss, so add a pilot-operated check valve for vertical lifts. The SAU family also adds a SAUF valve-integrated option the SU lacked.
Replacement checklist
- ✓ Same bore / stroke → SAU63X245S
- ✓ 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 SU63X245S FAQ
Yes, the SU63X245S is discontinued. The direct replacement is the AirTAC SAU63X245S. It shares the same 63mm bore, 245mm stroke, 3/8" port, output force and SC-series mounting accessories. You can order the SAU63X245S without modifying your machine.
The cylinder provides 1559N push and 1402N pull at 0.5MPa, 2182N push at 0.7MPa, and a theoretical max of 318kgf at 1.0MPa. Because your SU has an -S magnet for legacy CS1-B/DS1-B switches, you must upgrade to CMSG/DMSG/EMSG sensors for the SAU replacement.
