This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU100X35H, 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 SU100X35H
The AirTAC SU63-100 Standard Cylinder SU100X35H is a double-acting profile-type standard cylinder with a Ø100mm bore and 35mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU100X35H, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU100X35H
The AirTAC SU100X35H is a discontinued double-acting profile-type cylinder with a 100 mm bore, 35 mm stroke, and Viton H high-temperature seals (0-150 C). It delivers 3927 N push and 3681 N pull at 0.5 MPa via a 1/2" port. The direct replacement is the SAU100X35H, which preserves the original extruded aluminum body dimensions, output force, and SC-series mounting accessories.
Because this SKU lacks a magnet, it cannot accept position sensors. If sensing is required on the upgrade, the SAU family uses modern CMSG/DMSG/EMSG switches (the legacy SU line relied on CS1-B/DS1-B), and also offers a SAUF variant with a built-in 4M solenoid valve.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU100X35H carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAU100X35H 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 SU100X35H Is Used
High-Force Pressing
Delivers 3927 N at 0.5 MPa for seating heavy bearings and bushings in hot automotive assembly zones, leveraging the Viton H seal.
Hot-Environment Clamping
Secures metal castings or welded frames at elevated ambient temperatures up to 150 C where standard TPU seals would fail.
Replacing the Airtac SU63-100 Standard Cylinder SU100X35H with the SAU100X35H
To replace this SU100X35H, order the SAU100X35H and verify the 1/2" port, M20x1.5 rod thread, and SC-series mounting brackets. This unit has the -H Viton seal for 0-150 C environments. Since it lacks an -S magnet, no sensor can be fitted; if you need position detection, the SAU replacement requires CMSG/DMSG/EMSG switches. Downsize to an 80 mm bore if 2513 N push @0.5 MPa is sufficient, or up the pressure to 0.7 MPa for 5497 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock for suspended loads. The 35 mm stroke is short enough to avoid rod-bending side-load issues.
Replacement checklist
- ✓ Same bore / stroke → SAU100X35H
- ✓ 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 SU100X35H FAQ
Yes, the SU100X35H is discontinued. The direct replacement is the SAU100X35H. It matches the 100 mm bore, 35 mm stroke, 1/2" port, output force, and SC-series mounting, while retaining the high-temperature Viton H seal option.
It pushes 3927 N and pulls 3681 N at 0.5 MPa, pushes 5497 N at 0.7 MPa, and reaches a theoretical max of 801 kgf at 1.0 MPa. It cannot hold a load without live air—the cushion only decelerates—so use an external rod lock for vertical holding. Also, this non-magnetic SKU cannot take sensors.
