This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X165S, 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 SU100X165S
The AirTAC SU63-100 Standard Cylinder SU100X165S is a double-acting profile-type standard cylinder with a Ø100mm bore and 165mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X165S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X165S
The AirTAC SU100X165S is a discontinued double-acting profile-type cylinder with a 100mm bore and 165mm stroke, delivering 3927 N push force at 0.5 MPa. The direct replacement is the SAU100X165S, matching the 1/2" port, M20x1.5 rod thread, output force, and SC-series mounting.
This compact extruded aluminum body is shorter than an ISO 15552 equivalent. The -S magnet on this legacy unit worked with CS1-B/DS1-B switches, but the SAU replacement uses current CMSG/DMSG/EMSG sensors; SAU also adds a SAUF built-in-valve option.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAU100X165S 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 SU100X165S Is Used
Heavy Press Clamping
Secures large metal castings in machining fixtures, utilizing the 3927 N push force at 0.5 MPa to hold components firmly against cutting forces.
Mold Ejection Systems
Drives the ejection plate of large plastic injection molds, relying on the 29 mm adjustable air cushions to decelerate the 100 mm piston smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU100X165S with the SAU100X165S
To replace this SU100X165S, order the SAU100X165S and confirm the 1/2" port, M20x1.5 thread, and SC-series mounting. Because this SKU has the -S magnet, note the sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG. Sizing both ways: a neighboring 80mm bore yields 2513 N [email protected], while the 100mm hits 5497 N at 0.7 MPa. A plain cylinder drifts without live air—the 29mm cushions only decelerate; use an external rod lock for holding. The SAUF valve-integrated variant is a new option. At 165mm stroke, rod bending is low, but always guide side loads.
Replacement checklist
- ✓ Same bore / stroke → SAU100X165S
- ✓ 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 SU100X165S FAQ
Yes, the AirTAC SU100X165S is discontinued. The direct replacement is the SAU100X165S. It shares the identical 100mm bore, 165mm stroke, 1/2" port, output force, and SC-series mounting, so it fits the same application directly.
This double-acting cylinder delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and a theoretical max of 801 kgf at 1.0 MPa. The -S suffix denotes a piston magnet for legacy CS1-B/DS1-B switches; the SAU replacement upgrades this to CMSG/DMSG/EMSG sensors.
