This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X200N, 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.

The AirTAC SU63-100 Standard Cylinder SU63X200N is a double-acting profile-type standard cylinder with a Ø63mm bore and 200mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X200N, which matches its bore, stroke, force and mounting.
The AirTAC SU63X200N is a discontinued double-acting profile-type cylinder with a 63 mm bore and 200 mm stroke. It delivers 1559 N push force at 0.5 MPa through a 3/8" port. AirTAC replaced this end-of-line unit with the SAU63X200N, a direct upgrade retaining the exact bore, stroke, output force, port size, M16x1.5 rod thread and SC-series mounting.
This NBR-sealed variant operates from -20 to +70 C. Because this SKU lacks a magnet, it cannot accept a sensor; the SAU upgrade with a magnet uses modern CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X200N carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAU63X200N produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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.
Actuates routing gates on packaging lines, using the 1559 N push force to redirect heavy cartons at 0.5 MPa operating pressure.
Drives 200 mm stroke clamping arms to secure aluminum extrusions during CNC machining, utilizing the 3/8" port for rapid response.
To replace this discontinued SU63X200N, order the SAU63X200N. Confirm the 63 mm bore, 200 mm stroke, 3/8" port (default PT thread), M16x1.5 rod thread and your SC-series mounting (LB/FA/FB/CA/CB). This non-magnetic SKU cannot take a switch; if sensing is needed on the SAU, add an S suffix and migrate to CMSG/DMSG/EMSG sensors. For higher loads, the 80 mm bore offers 2513 N push at 0.5 MPa; for lighter duties, the 50 mm bore provides 982 N. Note: a plain cylinder drifts on air loss—the 21 mm cushions only decelerate. Use an external rod lock or pilot-operated check valve for load holding. The SAUF variant adds a built-in 4M valve the SU lacked. At 200 mm, side-load is low, but guide rods help if pushing off-center.
Replacement checklist
Yes, the SU63X200N is discontinued. The direct replacement is the SAU63X200N. It matches the 63 mm bore, 200 mm stroke, 1559 N force, 3/8" port, and SC-series mounting. You simply order the SAU equivalent.
At 0.5 MPa it pushes 1559 N and pulls 1402 N. It pushes 2182 N at 0.7 MPa, 2805 N at 0.9 MPa, with a 318 kgf max at 1.0 MPa. The 21 mm cushions only decelerate; the cylinder drifts without air, so use an external rod lock for holding.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU63X200N replacement — usually within 7-8 hours.
