This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X510S, 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 SU63X510S
The AirTAC SU63-100 Standard Cylinder SU63X510S is a double-acting profile-type standard cylinder with a Ø63mm bore and 510mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X510S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X510S
The AirTAC SU63X510S is a discontinued double-acting profile-type cylinder with a 63 mm bore and 510 mm stroke. It delivers 1559 N push force at 0.5 MPa through a 3/8" port. AirTAC replaced this EOL unit with the SAU63X510S, a direct alternative retaining the exact same body dimensions, output, and SC-series mounting.
Because this is an extruded aluminum profile cylinder, it is more compact than an ISO 15552 unit of the same bore. Note the -S magnet on this legacy model required CS1-B/DS1-B switches, whereas the SAU replacement utilizes the current CMSG/DMSG/EMSG sensor family.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X510S 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 SAU63X510S 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 SU63X510S Is Used
Long-Stroke Diverting
Pushes packages across a 500 mm transfer lane using the 510 mm stroke, relying on external guides to prevent rod bending during lateral diversion.
Vertical Lift Gate
Raises a 70 kg access gate, safely under the 79 kg vertical lift limit, but requires a pilot-operated check valve to prevent crashing down on air loss.
Multi-Stage Ejection
Ejects machined parts from a deep fixture, utilizing the 1559 N push force at 0.5 MPa to clear the workspace before the next cycle begins.
Replacing the Airtac SU63-100 Standard Cylinder SU63X510S with the SAU63X510S
To replace this SU63X510S, order the SAU63X510S direct equivalent, verifying your 3/8" port, M16x1.5 rod thread, and SC-series mounting hardware. If you need less force, a 50 mm bore provides 982 N push at 0.5 MPa; if you need more, an 80 mm bore yields 2513 N. The 510 mm stroke demands attention: use an external guide to prevent rod bending and side-load damage. The -S piston magnet means you must upgrade from legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. Finally, this cylinder cannot hold a load without live air—the cushions only decelerate—so install an external rod lock or pilot-operated check valve for vertical holding. The SAU line also offers a SAUF variant with a built-in valve if you need integrated flow control.
Replacement checklist
- ✓ Same bore / stroke → SAU63X510S
- ✓ 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 SU63X510S FAQ
Yes, the SU63X510S is discontinued. The direct replacement is the AirTAC SAU63X510S. It matches the 63 mm bore, 510 mm stroke, 3/8" port, and SC-series mounting. The main change is that your legacy CS1-B/DS1-B switches must be replaced with CMSG/DMSG/EMSG sensors for the new unit.
The 3/8" port cylinder delivers 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a theoretical maximum of 318 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa, with adjustable air cushions of 21 mm at both ends.
