This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X150CA, 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 SU63X150CA
The AirTAC Airtac SU63-100 Standard Cylinder SU63X150CA is a double-acting profile-type standard cylinder with a Ø63mm bore and 150mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X150CA, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X150CA
The AirTAC SU63X150CA is a discontinued double-acting profile-type cylinder with a 63 mm bore and 150 mm stroke. It delivers 1559 N push and 1402 N pull at 0.5 MPa, operating through a 3/8" port. AirTAC replaced this end-of-line unit with the SAU63X150CA, a direct upgrade retaining the exact bore, stroke, output force, and SC-series CA mounting interface.
Because this SKU lacks a magnet, it cannot accept a sensing switch. The SAU successor also omits one but can be ordered with an -S magnet for current CMSG/DMSG/EMSG switches, replacing the legacy CS1-B/DS1-B family. Note that the cushion only decelerates; it does not hold the load without live air.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X150CA 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 SAU63X150CA 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 SU63X150CA Is Used
Clamp Actuation
Secures heavy workpieces on machining fixtures, utilizing the 1559 N push force at 0.5 MPa to hold components firmly during milling or drilling operations.
Package Diverting
Drives a CA-mounted pivoting arm to redirect medium-weight cartons on sorting lines, benefiting from the compact profile body and 150 mm stroke.
Pallet Stopping
Acts as a pneumatic stop gate at palletizing stations, using its 1402 N pull force to retract the barrier and allow 79 kg vertical-lift equivalent loads to pass.
Replacing the Airtac SU63-100 Standard Cylinder SU63X150CA with the SAU63X150CA
To replace the SU63X150CA, order the SAU63X150CA, verifying the 63 mm bore, 150 mm stroke, 3/8" port, M16x1.5 rod thread, and CA clevis mount. If stepping down, a 50 mm bore yields 982 N push at 0.5 MPa; stepping up to 80 mm provides 2513 N. This non-magnetic SKU cannot take a sensor, but if you need position detection on the SAU, add the -S option and migrate to CMSG/DMSG/EMSG switches. A plain cylinder drifts on air loss, so use an external rod lock for holding. The SAUF variant offers a built-in valve the SU lacked. At 150 mm stroke, side-load risk is low, but ensure alignment to prevent rod bending.
Replacement checklist
- ✓ Same bore / stroke → SAU63X150CA
- ✓ 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 SU63X150CA FAQ
Yes, the SU63X150CA is discontinued. The direct replacement is the AirTAC SAU63X150CA. It shares the identical 63 mm bore, 150 mm stroke, 3/8" port, output force, and SC-series CA mounting, 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, 2805 N at 0.9 MPa, and a 318 kgf maximum at 1.0 MPa. This specific SKU has no magnet and cannot take a sensor. The SAU replacement with an -S option uses CMSG/DMSG/EMSG switches, upgrading from the old CS1-B/DS1-B.
