This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X250H, 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 SU63X250H
The AirTAC SU63-100 Standard Cylinder SU63X250H is a double-acting profile-type standard cylinder with a Ø63mm bore and 250mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X250H, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X250H
The AirTAC SU63X250H is a discontinued double-acting profile-type cylinder with a 63 mm bore, 250 mm stroke, and a Viton H high-temperature seal rated for 0 to 150 C. It delivers 1559 N push force at 0.5 MPa via a 3/8" port. AirTAC replaced this unit with the SAU63X250H, a direct alternative retaining the exact bore, stroke, output, port size, and SC-series mounting.
This compact extruded body is shorter than same-bore ISO 15552 units. The upgrade switches legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors and adds the SAUF built-in-valve option. This SKU lacks a magnet, so it cannot accept a sensor.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X250H 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 SAU63X250H 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 SU63X250H Is Used
Hot Stamp Press Ejection
Handles part ejection in heated presses where Viton H seals survive 150 C ambient temperatures, using 1559 N push force at 0.5 MPa to clear heavy molded components reliably.
Oven Door Automation
Opens and closes industrial curing oven doors, where the high-temperature FKM seals prevent degradation and the 3/8" port delivers rapid actuation speeds.
Replacing the Airtac SU63-100 Standard Cylinder SU63X250H with the SAU63X250H
To replace this cylinder, order the SAU63X250H, matching the 63 mm bore, 250 mm stroke, M16x1.5 rod thread, 3/8" port, and SC-series mounting. Because this SKU has no -S magnet, it cannot support sensing; if detection is needed, specify an SAU with -S and use CMSG/DMSG/EMSG switches. Sizing both ways: a 50 mm bore gives 982 N push at 0.5 MPa, while an 80 mm bore yields 2513 N. For high-temperature environments up to 150 C, retain the Viton H seal. At 250 mm stroke, guide external rods to prevent side-load bending. The air cushion only decelerates the piston; use an external rod lock or pilot-operated check valve to hold loads securely, and consider the SAUF valve-integrated variant for self-switching.
Replacement checklist
- ✓ Same bore / stroke → SAU63X250H
- ✓ 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 SU63X250H FAQ
Yes, the AirTAC SU63X250H is discontinued. The direct replacement is the SAU63X250H. It shares the identical 63 mm bore, 250 mm stroke, 1559 N force at 0.5 MPa, 3/8" port, and SC-series mounting accessories, but upgrades the sensor family to CMSG/DMSG/EMSG.
The 3/8" ported 63 mm bore yields 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N push at 0.9 MPa, and a theoretical maximum of 318 kgf at 1.0 MPa. Note that this specific SKU lacks a magnet and cannot accept position sensors.
