This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X220, 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 SU63X220
The AirTAC Airtac SU63-100 Standard Cylinder SU63X220 is a double-acting profile-type standard cylinder with a Ø63mm bore and 220mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X220, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X220
The AirTAC SU63X220 is a discontinued double-acting profile-type cylinder with a 63 mm bore and 220 mm stroke. Built with an extruded aluminum barrel, it is more compact than an ISO 15552 cylinder of the same bore. It delivers 1559 N push force at 0.5 MPa via a 3/8" port. AirTAC replaced this unit with the SAU63X220, a direct replacement retaining the exact bore, stroke, output force, port size, and SC-series mounting.
Because this SKU lacks a magnet (-S), it cannot accept a sensor. The SAU upgrade also introduces the SAUF built-in 4M valve variant, which the SU line never offered. Note that the air cushions only decelerate the piston near stroke end; they do not hold the load on air loss.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X220 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 SAU63X220 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 SU63X220 Is Used
Clamp Actuation
Drives a 63 mm bore clamping mechanism holding workpieces, delivering 1559 N push at 0.5 MPa for secure machining.
Pallet Stops
Extends 220 mm to halt pallets on a gravity conveyor, using adjustable end cushions to decelerate the load smoothly.
Replacing the Airtac SU63-100 Standard Cylinder SU63X220 with the SAU63X220
To replace the SU63X220, order the SAU63X220. Confirm the 3/8" port, M16x1.5 rod thread, and PT/G/NPT thread preference. If you need position sensing, this no-magnet SKU cannot take a switch; you must add a magnet and note that the SAU uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B. Sizing both ways: dropping to a 50 mm bore yields 982 N push at 0.5 MPa, while stepping up to an 80 mm bore provides 2513 N. At 220 mm stroke, guide the load to prevent rod bending and side-load wear. For load holding on air loss, add an external rod lock or pilot-operated check valve, as cushions only decelerate. Consider the SAUF variant if you need a self-switching built-in valve.
Replacement checklist
- ✓ Same bore / stroke → SAU63X220
- ✓ 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 SU63X220 FAQ
Yes, the SU63X220 is discontinued. The direct replacement is the AirTAC SAU63X220. It shares the identical 63 mm bore, 220 mm stroke, 1559 N output force, 3/8" port, and SC-series mounting accessories, so it fits the same application directly.
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. Because this specific SKU lacks a magnet, it cannot accept a sensor. The SAU replacement supports CMSG/DMSG/EMSG switches, whereas the older SU used CS1-B/DS1-B.
