This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X105, 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 SU63X105 is a double-acting profile-type standard cylinder with a Ø63mm bore and 105mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X105, which matches its bore, stroke, force and mounting.
The AirTAC SU63X105 is a discontinued double-acting profile-type cylinder with a 63 mm bore and 105 mm stroke. It delivers 1559 N push force at 0.5 MPa through an extruded aluminium barrel, making it shorter than an ISO 15552 cylinder of the same size. AirTAC replaced this end-of-life unit with the SAU63X105, a direct replacement retaining the exact 3/8" port, M16x1.5 rod thread, and SC-series mounting.
Because this SKU lacks a magnet (-S), it cannot accept a sensor; the SAU upgrade switches to CMSG/DMSG/EMSG switches if you order the -S version. The SAU line also adds a SAUF built-in-valve option the SU never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X105 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 SAU63X105 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 63 | Bore size in mm. |
| ×105 | Stroke length in mm. |
| -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.
Provides robust 1559 N push force at 0.5 MPa to divert heavy cartons on a packing line, with the 105 mm stroke moving packages cleanly between parallel conveyor belts.
Ideal for securing medium-weight steel profiles during machining, using the 63 mm bore's 318 kgf maximum theoretical force to hold parts rigidly against cutting vibration.
Functions as a pneumatic stop gate for inbound pallets, where the compact profile body saves space and the 21 mm adjustable cushions absorb the impact at stroke end.
To replace the SU63X105, order the SAU63X105 with the same 105 mm stroke, 3/8" port, and SC-series mounts (LB/FA/FB/CA/CB). Confirm your thread option (PT, G, or NPT). This non-magnet SKU cannot take a switch; if you need sensing on the SAU, add -S and use CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. If you need integrated flow control, explore the SAUF valve variant. Neighbouring bores: 50 mm gives 982 N push @0.5 MPa, while 80 mm yields 2513 N. Note: a plain cylinder drifts on air loss—the cushion only decelerates; use a pilot-operated check valve for load holding.
Replacement checklist
Yes, the AirTAC SU63X105 is discontinued. The direct replacement is the SAU63X105. It matches the 63 mm bore, 105 mm stroke, 1559 N force, 3/8" port, and SC-series mounting accessories. You simply swap the cylinder without modifying the machine.
At 0.5 MPa it pushes 1559 N and pulls 1402 N; at 0.7 MPa it pushes 2182 N, with a theoretical max of 318 kgf at 1.0 MPa. This specific SKU has no magnet (-S), so it cannot accept a sensor. If you order the SAU63X105-S replacement, you must use current CMSG/DMSG/EMSG switches, as the old CS1-B/DS1-B sensors are obsolete.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU63X105 replacement — usually within 7-8 hours.
