This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X150, 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 SU63X150
The AirTAC Airtac SU63-100 Standard Cylinder SU63X150 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 SAU63X150, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X150
The AirTAC SU63X150 is a discontinued double-acting profile-type cylinder with a 63 mm bore and 150 mm stroke. It delivers 1559 N push force at 0.5 MPa through a 3/8" port. AirTAC replaced this unit with the SAU63X150 direct replacement, matching the exact bore, stroke, output force, port size and SC-series mounting accessories.
Because the SU is end-of-life, ordering the SAU63X150 is the correct path. The upgrade introduces CMSG/DMSG/EMSG sensors (replacing the legacy CS1-B/DS1-B switches) and adds a SAUF built-in-valve option the SU lacked. Mechanically, the extruded aluminium profile remains shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X150 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 SAU63X150 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 SU63X150 Is Used
Package Diverting
Actuates routing gates on packaging lines, utilising the 1559 N push force to deflect heavy cartons reliably at 0.5 MPa.
Pallet Stopping
Deploys a 150 mm stroke to halt pallets at processing stations, absorbing kinetic energy via the 21 mm adjustable air cushions.
Clamping Fixtures
Secures workpieces during machining operations, providing consistent 1402 N pull force for stable holding without live load locking.
Replacing the Airtac SU63-100 Standard Cylinder SU63X150 with the SAU63X150
To replace the SU63X150, order the SAU63X150 and verify your 3/8" port, M16x1.5 rod thread, and SC-series mounting hardware (LB/FA/FB/CA/CB) remain compatible. This 150 mm stroke is well within the 1500 mm standard maximum, so no side-load guide is strictly required, though external guides benefit high-mass loads. If sizing neighbours, the 50 mm bore yields 982 N push at 0.5 MPa while the 80 mm bore yields 2513 N. Note this non-magnetic SKU cannot accept a sensor; if you previously required a magnet, the SAU equivalent uses CMSG/DMSG/EMSG switches. A plain cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock or pilot-operated check valve for held loads. For automated setups, consider the SAUF variant with its integrated 4M solenoid valve.
Replacement checklist
- ✓ Same bore / stroke → SAU63X150
- ✓ 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 SU63X150 FAQ
Yes, the SU63X150 is discontinued and end-of-life. The direct replacement is the AirTAC SAU63X150. It shares the identical 63 mm bore, 150 mm stroke, 3/8" port, output force, and SC-series mounting, so it fits the same application directly.
At 0.5 MPa it provides 1559 N push and 1402 N pull; 2182 N push at 0.7 MPa; 2805 N at 0.9 MPa; and a theoretical max of 318 kgf at 1.0 MPa. This specific non-magnetic SKU cannot take a sensor. If sensing is needed, the SAU63X150 replacement supports CMSG/DMSG/EMSG switches, replacing the legacy CS1-B/DS1-B.
