This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X210, 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 SU63X210
The AirTAC Airtac SU63-100 Standard Cylinder SU63X210 is a double-acting profile-type standard cylinder with a Ø63mm bore and 210mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X210, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X210
The AirTAC SU63X210 is a discontinued double-acting profile-type cylinder with a 63 mm bore and 210 mm stroke. It delivers 1559 N push force at 0.5 MPa through a 3/8" port. AirTAC replaced this legacy unit with the SAU63X210, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series mounting.
The SAU upgrade introduces current CMSG/DMSG/EMSG sensors, unlike this older unit which used CS1-B/DS1-B switches. This specific SKU lacks a magnet, so it cannot accept any sensor. The SAU family also adds a SAUF valve-integrated variant the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X210 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 SAU63X210 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 SU63X210 Is Used
Package Diversion
Actuates routing gates on packaging lines, using the 1559 N push force to reliably pivot heavy cardboard cartons at high speeds.
Pallet Stopper
Deploys a 210 mm stroke to halt incoming pallets at loading stations, absorbing kinetic energy via the adjustable 21 mm cushions.
Clamp Actuation
Secures aluminum extrusions during machining operations, providing repeatable clamping with a 79 kg safe vertical lifting margin.
Replacing the Airtac SU63-100 Standard Cylinder SU63X210 with the SAU63X210
To replace this SU63X210, order the SAU63X210. Verify your 3/8" port, M16x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB) carry over directly. Because this SKU has no magnet, it cannot hold a sensor; if you previously used an -S model, note the SAU requires 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. At 210 mm, side-load risk is low, but always guide the rod to prevent bending. A plain cylinder drifts on air loss; for load holding, install an external rod lock or pilot-operated check valve, as cushions only decelerate. If you need integrated control, explore the SAUF built-in-valve option.
Replacement checklist
- ✓ Same bore / stroke → SAU63X210
- ✓ 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 SU63X210 FAQ
Yes, the AirTAC SU63X210 is discontinued and end-of-life. The direct replacement is the SAU63X210. It shares the identical 63 mm bore, 210 mm stroke, 3/8" port, and SC-series mounting, so it bolts right in without modifications.
At 0.5 MPa it pushes 1559 N and pulls 1402 N. Push force is 2182 N at 0.7 MPa and 2805 N at 0.9 MPa, with a theoretical max of 318 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept a sensor; legacy -S versions used CS1-B/DS1-B switches, while the SAU replacement uses CMSG/DMSG/EMSG sensors.
