This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X30H, 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 SU63X30H
The AirTAC SU63-100 Standard Cylinder SU63X30H is a double-acting profile-type standard cylinder with a Ø63mm bore and 30mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X30H, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X30H
The AirTAC SU63X30H is a discontinued double-acting profile-type cylinder with a 63 mm bore, 30 mm stroke, and Viton H high-temperature seals rated for 0 to 150 C. It delivers 1559 N push force at 0.5 MPa via a 3/8 inch port. AirTAC replaced this end-of-life unit with the SAU63X30H, a direct replacement retaining the exact bore, stroke, output force, and SC-series mounting.
This compact extruded-aluminium body is shorter than an ISO 15552 cylinder of the same size. The SAU upgrade introduces CMSG/DMSG/EMSG sensors and a SAUF built-in-valve option the SU lacked. Because this SKU has no magnet, it cannot accept a sensor.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X30H 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 SAU63X30H 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 SU63X30H Is Used
Hot Stamp Ejection
Short 30 mm kickout of finished parts from a 150 C hot stamping die, leveraging the Viton H seals to survive ambient radiant heat without degrading.
High-Temp Divert
Actuating a short-stroke diverter gate on an oven discharge belt, where the 1559 N thrust easily overcomes friction and the compact profile fits tight guard clearances.
Replacing the Airtac SU63-100 Standard Cylinder SU63X30H with the SAU63X30H
To replace this SU63X30H, order the SAU63X30H direct equivalent, confirming the 63 mm bore, 30 mm stroke, M16x1.5 rod thread, 3/8 inch port, and SC-series mounting hardware are retained. If stepping up to an 80 mm bore yields more thrust (2513 N at 0.5 MPa), or dropping to a 50 mm bore saves space (982 N), adjust accordingly. This -H Viton seal variant handles 150 C environments. Note that this non-magnetic SKU cannot support sensing; if detection is needed, the SAU family requires CMSG/DMSG/EMSG switches. For load holding on air loss, add an external rod lock or pilot-operated check valve, as the cushions only decelerate.
Replacement checklist
- ✓ Same bore / stroke → SAU63X30H
- ✓ 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 SU63X30H FAQ
Yes, the SU63X30H is discontinued. The direct replacement is the AirTAC SAU63X30H. It shares the identical 63 mm bore, 30 mm stroke, 3/8 inch port, Viton H seals, and SC-series mounting, so it bolts right in. The SAU line also adds a SAUF valve-integrated option the SU never had.
At 0.5 MPa it pushes 1559 N and pulls 1402 N; at 0.7 MPa it pushes 2182 N, with a theoretical max of 318 kgf at 1.0 MPa. Because this specific SKU lacks a magnet (-S), it cannot accept a sensor. The SAU replacement uses CMSG/DMSG/EMSG switches, but you would need a magnet-equipped model for detection.
