This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X300H, 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 SU63X300H
The AirTAC SU63-100 Standard Cylinder SU63X300H is a double-acting profile-type standard cylinder with a Ø63mm bore and 300mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X300H, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X300H
The AirTAC SU63X300H is a discontinued double-acting profile-type cylinder with a 63 mm bore and 300 mm stroke. Built with an extruded aluminium barrel and adjustable air cushions, it delivers 1559 N push force at 0.5 MPa while being more compact than an ISO 15552 cylinder of the same bore. The direct replacement is the SAU63X300H, which matches the body, 3/8" port, M16x1.5 rod thread and SC-series mounting.
This -H variant specifies a Viton FKM seal for 0-150 C high-temperature environments. Note this SKU lacks a magnet and cannot accept sensors; furthermore, the SAU upgrade switches to CMSG/DMSG/EMSG switches and adds a SAUF built-in-valve option the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X300H 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 SAU63X300H produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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 SU63X300H Is Used
High-Temperature Ejection
Ejecting molded parts from hot environments using the Viton -H seal rated for 0-150 C, delivering 1559 N push force at 0.5 MPa to clear heavy components reliably.
Long-Stroke Diversion
Diverting products across a wider belt path with the 300 mm stroke, requiring external guides to prevent side-load bending on the 20 mm rod during transit.
Replacing the Airtac SU63-100 Standard Cylinder SU63X300H with the SAU63X300H
To replace this discontinued SU63X300H, order the SAU63X300H direct equivalent, confirming the 63 mm bore, 300 mm stroke, 3/8" port and SC-series mounting accessories are retained. Because this is a no-S SKU, it cannot take a magnetic sensor; if sensing is needed, the SAU replacement requires CMSG/DMSG/EMSG switches. Sizing both ways: a 50 mm bore offers 982 N push at 0.5 MPa, while an 80 mm bore provides 2513 N. At 300 mm stroke, prevent rod bending by supporting the load with an external guide. The cushion only decelerates the piston; for load holding on air loss, install an external rod lock or pilot-operated check valve. The Viton -H seal handles up to 150 C.
Replacement checklist
- ✓ Same bore / stroke → SAU63X300H
- ✓ 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 SU63X300H FAQ
Yes, the SU63X300H is discontinued. The direct replacement is the SAU63X300H. It matches the 63 mm bore, 300 mm stroke, 1559 N force at 0.5 MPa, 3/8" port and SC-series mounting. The SAU body is identical, but if you need sensing, it uses CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
The 63 mm bore provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N at 0.9 MPa, and a theoretical max of 318 kgf at 1.0 MPa. This specific SU63X300H SKU lacks a magnet and cannot accept sensors. The SAU replacement supports CMSG/DMSG/EMSG switches and offers a SAUF variant with a built-in 4M solenoid valve.
