This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X165, 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 SU63X165
The AirTAC Airtac SU63-100 Standard Cylinder SU63X165 is a double-acting profile-type standard cylinder with a Ø63mm bore and 165mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X165, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X165
The AirTAC SU63X165 is a discontinued double-acting profile-type cylinder with a 63mm bore and 165mm stroke. It delivers 1559 N push and 1402 N pull at 0.5 MPa, peaking at a 318 kgf theoretical maximum. Because this exact stroke is non-standard, the direct replacement is the SAU63X165, matching the bore, stroke, 3/8" port, M16x1.5 rod thread and SC-series mounting.
This extruded aluminium body is more compact than an ISO 15552 equivalent. Note this non-magnetic SKU cannot accept a sensor; the SAU family uses CMSG/DMSG/EMSG switches, and the SAUF variant adds a built-in valve the SU lacked.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X165 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 SAU63X165 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SU63-100 Standard Cylinder SU63X165 Is Used
Mid-Tonnage Clamping
Secures heavy workpieces in CNC machining fixtures, using the 1559 N push force at 0.5 MPa to hold parts rigidly against cutting forces.
Package Diversion
Actuates sorting arms on logistics lines, where the 1402 N pull force reliably retracts the mechanism to reroute heavy cartons.
Pallet Stopper Gates
Controls pallet flow on roller conveyors by raising and lowering stop gates, benefiting from the compact profile body to fit tight transfer zones.
Replacing the Airtac SU63-100 Standard Cylinder SU63X165 with the SAU63X165
To replace the SU63X165, order the SAU63X165. Verify your 3/8" port, M16x1.5 rod thread, PT/G/NPT thread standard, and SC-series mounting (LB/FA/FB/CA/CB) so it drops straight in. If sizing alternatives, a 50mm bore yields 982 N push at 0.5 MPa, while an 80mm bore yields 2513 N. Since this 165mm stroke is non-standard and exceeds 300mm designs, ensure adequate guide rails to prevent rod bending under side loads. 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. If self-switching is needed, explore the SAUF valve-integrated option.
Replacement checklist
- ✓ Same bore / stroke → SAU63X165
- ✓ 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 SU63X165 FAQ
Yes, the AirTAC SU63X165 is discontinued and end-of-life. The direct replacement is the SAU63X165. It shares the identical 63mm bore, 165mm stroke, 318 kgf max force, 3/8" port, and SC-series mounting, so it fits the same application without modification.
At 0.5 MPa it pushes 1559 N and pulls 1402 N; at 0.7 MPa it pushes 2182 N, with a 318 kgf theoretical max at 1.0 MPa. This specific SKU lacks a magnet and cannot take a sensor. The SAU replacement uses CMSG/DMSG/EMSG switches, whereas older SU-S models used CS1-B/DS1-B.
