This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X950S, 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 SU63X950S
The AirTAC Airtac SU63-100 Standard Cylinder SU63X950S is a double-acting profile-type standard cylinder with a Ø63mm bore and 950mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X950S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X950S
The AirTAC SU63X950S is a discontinued double-acting profile-type cylinder with a 63 mm bore and 950 mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 cylinder of the same bore and delivers 1559 N push force at 0.5 MPa. The direct replacement is the SAU63X950S, matching the bore, stroke, output force, 3/8" port, and SC-series mounting.
The -S magnet on this legacy model worked with CS1-B/DS1-B switches; the SAU replacement uses current CMSG/DMSG/EMSG sensors. The SAU family also adds a SAUF variant with a built-in valve, an option the SU line lacked. Note that a plain cylinder drifts without live air; use an external rod lock for load holding.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X950S 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 SAU63X950S 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 SU63X950S Is Used
Automated Press Ejection
Ejects formed parts from machinery, relying on the 3/8" port and adjustable 21 mm cushions to decelerate the 20 mm rod at high speeds.
Replacing the Airtac SU63-100 Standard Cylinder SU63X950S with the SAU63X950S
To replace this SU63X950S, order the SAU63X950S, confirming the 63 mm bore, 950 mm stroke, 3/8" port, M16x1.5 rod thread, and SC-series mounting accessories. Because this -S SKU has a magnet, you must switch from the legacy CS1-B/DS1-B switches to the CMSG/DMSG/EMSG sensor family on the new cylinder. If you need integrated flow control, the SAUF variant includes a built-in 4M solenoid valve. For sizing alternatives, dropping to a 50 mm bore yields 982 N push at 0.5 MPa, while stepping up to an 80 mm bore provides 2513 N. At a 950 mm stroke, avoid side-load and rod-bending forces by using an external guide to support the piston rod. Remember that the adjustable air cushion only decelerates the piston near the end of travel; it does not hold the load. For secure positioning on air loss, install a pilot-operated check valve or external rod lock.
Replacement checklist
- ✓ Same bore / stroke → SAU63X950S
- ✓ 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 SU63X950S FAQ
Yes, the AirTAC SU63X950S is discontinued and end-of-life. The direct replacement is the SAU63X950S. It matches the 63 mm bore, 950 mm stroke, 3/8" port, output force, and SC-series mounting. You can swap it directly without changing your mechanical setup.
The 63 mm bore provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a theoretical max of 318 kgf at 1.0 MPa. Because this is an -S magnet model, the legacy CS1-B/DS1-B switches are retired; the SAU replacement requires the current CMSG/DMSG/EMSG sensor family.
