This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X63, 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 SU63X63
The AirTAC SU63-100 Standard Cylinder SU63X63 is a double-acting profile-type standard cylinder with a Ø63mm bore and 63mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X63, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X63
The AirTAC SU63X63 is a discontinued double-acting profile-type cylinder. It delivers 1559 N push and 1402 N pull at 0.5 MPa via a 3/8 inch port. The direct replacement is the SAU63X63, matching the 63 mm bore, 63 mm stroke, force, and SC-series mounts.
This extruded aluminium body is shorter than an ISO 15552 equivalent. Lacking a magnet, this SKU takes no sensor; the SAU upgrade uses CMSG/DMSG/EMSG switches and offers a SAUF built-in valve option.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X63 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 SAU63X63 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 SU63X63 Is Used
Package Diversion
Pushes medium-weight cartons off a sorting line using a 63 mm bore, absorbing end-of-stroke impact with its 21 mm adjustable cushion.
Pallet Lift Gate
Raises a light pallet gate with a safe vertical lift capacity around 79 kg, fitting neatly into existing SC-series mounting brackets.
Clamp Actuation
Secures workpieces during machining by applying 1559 N of clamping force at 0.5 MPa without needing a larger 80 mm body.
Replacing the Airtac SU63-100 Standard Cylinder SU63X63 with the SAU63X63
To replace this SU63X63, order the SAU63X63 ensuring your 3/8 inch port thread (PT/G/NPT) and M16x1.5 rod end match. This non-magnetic SKU cannot take a switch, but if you previously used an -S model, note the SAU uses CMSG/DMSG/EMSG sensors instead of legacy CS1-B/DS1-B. For sizing, the 50 mm bore yields 982 N push at 0.5 MPa, while the 80 mm bore provides 2513 N. Because a plain cylinder drifts on air loss, use an external rod lock for held loads. The SAUF variant integrates a 4M valve if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU63X63
- ✓ 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 SU63X63 FAQ
Yes, the SU63X63 is discontinued. The direct replacement is the AirTAC SAU63X63. It shares the identical 63 mm bore, 63 mm stroke, 1559 N output force at 0.5 MPa, 3/8 inch port, and SC-series mounting accessories.
It delivers 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a theoretical max of 318 kgf at 1.0 MPa. This specific SKU lacks a magnet and cannot accept a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches.
