This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X100H, 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 SU63X100H
The AirTAC SU63-100 Standard Cylinder SU63X100H is a double-acting profile-type standard cylinder with a Ø63mm bore and 100mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X100H, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X100H
The AirTAC SU63X100H is a discontinued double-acting profile-type cylinder with a 63 mm bore and 100 mm stroke. Featuring an extruded aluminum barrel, it is shorter and more compact than an ISO 15552 cylinder of the same bore. This Viton H (FKM) seal variant operates up to 150 C. As a standard unit without a magnet (-S), it cannot accept magnetic sensors. The direct replacement is the SAU63X100H, matching the 3/8 inch port, M16x1.5 rod thread, and SC-series mounting.
Upgrading to the SAU retains these force characteristics but moves to current CMSG/DMSG/EMSG sensors. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, an option the SU line lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X100H 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 SAU63X100H 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 SU63X100H Is Used
High-Temperature Ejection
Ideal for pushing parts out of heated molds or ovens where the Viton H seal withstands ambient temperatures up to 150 C without degrading.
Mid-Force Clamping
Delivers 1559 N of push force at 0.5 MPa, providing secure holding for medium-duty machining or welding fixtures.
Replacing the Airtac SU63-100 Standard Cylinder SU63X100H with the SAU63X100H
To replace the discontinued SU63X100H, order the SAU63X100H direct equivalent, verifying the 63 mm bore, 100 mm stroke, 3/8 inch port, M16x1.5 rod thread, and SC-series mounting hardware are retained. Because this SKU lacks a magnet, it cannot support sensing; if detection is needed, an SAU model with a magnet and CMSG/DMSG/EMSG switches is required. For sizing alternatives, a 50 mm bore offers 982 N push at 0.5 MPa, while an 80 mm bore provides 2513 N. Note that a plain cylinder does not hold load without live air; use an external rod lock or pilot-operated check valve for holding. The SAUF valve-integrated option can simplify cycling.
Replacement checklist
- ✓ Same bore / stroke → SAU63X100H
- ✓ 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 SU63X100H FAQ
Yes, the SU63X100H is discontinued. The direct replacement is the SAU63X100H. It shares the same 63 mm bore, 100 mm stroke, 318 kgf max force, 3/8 inch port, and SC-series mounting. The SAU body is a direct physical swap, though it uses current CMSG/DMSG/EMSG sensors if you add a magnet.
The SU63X100H generates 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and 2805 N at 0.9 MPa, with a theoretical max of 318 kgf at 1.0 MPa. The Viton H seal allows operation from 0 to 150 C. It uses a 3/8 inch port and runs at 30-800 mm/s.
