This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X120TC, 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 SU63X120TC
The AirTAC SU63-100 Standard Cylinder SU63X120TC is a double-acting profile-type standard cylinder with a Ø63mm bore and 120mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X120TC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X120TC
The AirTAC SU63X120TC is a discontinued double-acting profile-type cylinder featuring a 63mm bore, 120mm stroke, and a TC mounting interface. Built with an extruded aluminum barrel, it delivers 1559 N of push force at 0.5 MPa while remaining more compact than an ISO 15552 cylinder of the same bore. AirTAC replaced this unit with the SAU63X120TC, a direct replacement matching the exact body, 3/8" port, M16x1.5 rod thread, and SC-series mounting accessories.
Because this SKU lacks a magnet, it cannot accept a position sensor. The SAU upgrade retains the physical dimensions and 318 kgf maximum force, but if you later need sensing, the SAU uses modern CMSG/DMSG/EMSG switches rather than the legacy CS1-B/DS1-B family.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X120TC 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 SAU63X120TC 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 SU63X120TC Is Used
Package Diverting
Drives a TC-mounted diverting arm on a packaging line, using the 120mm stroke to push cartons cleanly onto adjacent lanes.
Pallet Stopper Gate
Acts as a pneumatic stop gate for inbound pallets, leveraging the 1559 N push force to halt heavy loads without bouncing.
Clamp Actuation
Secures medium-weight aluminum extrusions during machining, providing rigid clamping via the compact profile body.
Replacing the Airtac SU63-100 Standard Cylinder SU63X120TC with the SAU63X120TC
To replace the discontinued SU63X120TC, order the SAU63X120TC and confirm your 3/8" port threads (PT, G, or NPT) alongside the TC mounting bracket. Since this non-magnetic SKU cannot hold a position switch, order a separate sensor groove mount if detection is needed. For loads requiring holding on air loss, add an external rod lock or pilot-operated check valve, as the adjustable cushions only decelerate near stroke ends. If downsizing, a 50mm bore yields 982 N push at 0.5 MPa; if upsizing, an 80mm bore provides 2513 N. The SAUF variant adds a built-in 4M solenoid valve for self-switching, an option the original SU line never offered.
Replacement checklist
- ✓ Same bore / stroke → SAU63X120TC
- ✓ 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 SU63X120TC FAQ
Yes, the SU63X120TC is discontinued. The direct replacement is the AirTAC SAU63X120TC. It shares the identical 63mm bore, 120mm stroke, 3/8" port, output force, and TC mounting interface, so it bolts right into the same machine.
At 0.5 MPa it pushes 1559 N and pulls 1402 N. It pushes 2182 N at 0.7 MPa and reaches a theoretical max of 318 kgf at 1.0 MPa. The cylinder cannot hold a load if air pressure drops; the cushions only decelerate the piston near stroke end. Use an external rod lock for secure load holding.
