This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X150CB, 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 SU63X150CB
The AirTAC Airtac SU63-100 Standard Cylinder SU63X150CB 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 SAU63X150CB, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X150CB
The AirTAC SU63X150CB is a discontinued double-acting profile-type standard cylinder with a 63 mm bore and 150 mm stroke. Built with an extruded aluminium barrel and adjustable air cushions at both ends, it delivers 1559 N push force at 0.5 MPa. AirTAC replaced this EOL unit with the SAU63X150CB, a direct replacement retaining the exact 3/8" port, M16x1.5 rod thread, 21 mm cushions and SC-series CB mounting interface.
This specific SKU lacks a magnet, so it cannot accept a magnetic switch. If sensing is needed on the SAU upgrade, note that the legacy CS1-B/DS1-B switches are replaced by the current CMSG/DMSG/EMSG family. The SAU line also introduces the SAUF variant with a built-in 4M solenoid valve, an option the original SU series never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X150CB 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 SAU63X150CB 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 SU63X150CB Is Used
Package Diverting
Actuates a CB-mounted clevis diverter arm on a 63 mm bore line, reliably routing medium-weight cartons at speeds up to 800 mm/s.
Pallet Stop Gate
Leverages the 1559 N push force at 0.5 MPa to halt standard pallets on a gravity roller conveyor, using the 150 mm stroke to clear the path.
Press Ejection
Ejects formed metal components from a press bed, using the adjustable 21 mm air cushions to decelerate the 20 mm rod smoothly at stroke end.
Replacing the Airtac SU63-100 Standard Cylinder SU63X150CB with the SAU63X150CB
To replace this discontinued SU63X150CB, order the SAU63X150CB. Confirm the 63 mm bore, 150 mm stroke, 3/8" port (default PT thread), and the CB clevis mounting accessory from the AirTAC SC series. Because this SKU has no magnet (-S), it cannot support sensors; if your upgrade requires position detection, specify an SAU with a magnet and update to CMSG/DMSG/EMSG switches, as the older CS1-B/DS1-B units are obsolete. When sizing, the 63 mm bore yields 1559 N push and 1402 N pull at 0.5 MPa; if you need less force, step down to a 50 mm bore (982 N push), or step up to an 80 mm bore (2513 N push) for heavier loads. Remember that a standard cylinder does not hold a load on air loss—the cushion only decelerates near stroke end—so fit an external rod lock or pilot-operated check valve for vertical safety. At 150 mm stroke, side-load and rod-bending risks are minimal, but always ensure correct alignment.
Replacement checklist
- ✓ Same bore / stroke → SAU63X150CB
- ✓ 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 SU63X150CB FAQ
Yes, the AirTAC SU63X150CB is discontinued and end-of-life. The direct replacement is the SAU63X150CB. It features the same 63 mm bore, 150 mm stroke, 1559 N output force at 0.5 MPa, 3/8" port, and CB mounting interface, fitting directly into your existing SC-series accessory setup.
This double-acting cylinder delivers 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and a theoretical maximum of 318 kgf at 1.0 MPa. This specific SKU has no magnet (-S), meaning it cannot accept a magnetic switch. If sensing is required on the SAU replacement, you must use the newer CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
