This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X100CA, 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 Airtac SU63-100 Standard Cylinder SU63X100CA is a double-acting profile-type standard cylinder with a Ø63mm bore and 100mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X100CA, which matches its bore, stroke, force and mounting.
The AirTAC SU63X100CA is a discontinued double-acting profile-type cylinder with a 63 mm bore and 100 mm stroke. It delivers 1559 N push force at 0.5 MPa and uses a 3/8" port with an M16x1.5 rod thread. AirTAC replaced this unit with the SAU63X100CA, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series CA mounting interface.
Because the extruded aluminum profile body has no external rods, it is shorter and more compact than an ISO 15552 cylinder of the same bore. Note this specific SKU lacks a magnet (-S) and cannot accept a sensor; furthermore, a plain cylinder drifts on air loss, so use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X100CA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
The SAU63X100CA 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.
Holds workpieces securely in machining jigs utilizing the 1559 N push force at 0.5 MPa.
Pushes cartons off a main belt line using the compact 100 mm stroke and CA clevis mount.
To replace this discontinued SU63X100CA, order the SAU63X100CA. Confirm the 3/8" port, PT thread, and CA mounting are retained. This SKU has no magnet (-S), so it cannot take a switch; if sensing is needed, the SAU family uses modern CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B. Sizing both ways: a 50 mm bore gives 982 N push at 0.5 MPa, while an 80 mm bore gives 2513 N. At 100 mm stroke, side-load is minimal, but always guide the rod to prevent bending. The SAU also offers a SAUF variant with a built-in valve the SU lacked. For load holding, add a pilot-operated check valve, as cushions only decelerate.
Replacement checklist
Yes, the AirTAC SU63X100CA is discontinued. The direct replacement is the SAU63X100CA. It shares the identical 63 mm bore, 100 mm stroke, 318 kgf max force, 3/8" port, and SC-series CA mounting, fitting the same application directly.
At 0.5 MPa it pushes 1559 N and pulls 1402 N. At 0.7 MPa it pushes 2182 N, and the theoretical max is 318 kgf at 1.0 MPa. The 21 mm cushions only decelerate the piston; a plain cylinder cannot hold a load on air loss, so use an external rod lock for vertical safety.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU63X100CA replacement — usually within 7-8 hours.
