This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X1050S, 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 SU63X1050S
The AirTAC SU63-100 Standard Cylinder SU63X1050S is a double-acting profile-type standard cylinder with a Ø63mm bore and 1050mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X1050S, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X1050S
The AirTAC SU63X1050S is a discontinued double-acting profile-type cylinder with a 63mm bore and 1050mm stroke. As an end-of-line unit, it is replaced directly by the SAU63X1050S. This direct successor maintains the exact extruded aluminium body, 3/8" port, M16x1.5 rod thread, and SC-series mounting accessories.
Because this 1050mm stroke exceeds the 1000mm threshold, it is a nonstandard stroke requiring external guides to prevent rod bending under side loads. The -S magnet on this legacy unit paired with CS1-B/DS1-B switches; upgrading to the SAU requires current CMSG/DMSG/EMSG sensors. The SAU family also introduces the SAUF variant with a built-in 4M solenoid valve, a feature the original SU line lacked. Note that air cushions only decelerate the piston; a pilot-operated check valve is needed to hold loads.

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 SAU63X1050S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| 63 | Bore size in mm. |
| ×1050 | 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.
Where the Airtac SU63-100 Standard Cylinder SU63X1050S Is Used
Long-Stroke Material Transfer
Pushes heavy pallets along extended conveyor lines using the 1559 N force, where the 1050mm stroke spans wide machine gaps.
Extended-Axis Positioning
Actuates large sliding carriages over 1050mm distances, requiring external linear guides to absorb structural side loads.
Replacing the Airtac SU63-100 Standard Cylinder SU63X1050S with the SAU63X1050S
To replace the discontinued SU63X1050S, order the SAU63X1050S, confirming the 63mm bore, 1050mm stroke, 3/8" port, and PT/G/NPT thread choice. Retain your SC-series mounts (LB/FA/FB/CA/CB). If sizing alternatives, the adjacent 50mm bore yields 982 N push at 0.5 MPa, while the 80mm bore provides 2513 N. For this 1050mm stroke, external linear guides are mandatory to prevent rod-bending side loads. The -S magnet means you must switch from CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. Remember, standard cylinders drift without air; use an external rod lock for load holding. The SAUF valve-integrated option can simplify cycling.
Replacement checklist
- ✓ Same bore / stroke → SAU63X1050S
- ✓ 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 SU63X1050S FAQ
Yes, the SU63X1050S is discontinued. The direct replacement is the SAU63X1050S. It matches the 63mm bore, 1050mm stroke, 3/8" port, and SC-series mounting. The SAU body is identical, but you must update your sensors from CS1-B/DS1-B to CMSG/DMSG/EMSG.
The 63mm bore 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. The 1050mm stroke is nonstandard (exceeding the 1000mm max standard), so external guides are needed. The 3/8" port and 21mm cushions remain unchanged.
