This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X350TC, 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 SU63X350TC
The AirTAC SU63-100 Standard Cylinder SU63X350TC is a double-acting profile-type standard cylinder with a Ø63mm bore and 350mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X350TC, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X350TC
The AirTAC SU63X350TC is a discontinued double-acting profile-type cylinder featuring a 63 mm bore and 350 mm stroke. It delivers 1559 N push force at 0.5 MPa through a 3/8 inch port. AirTAC replaced this legacy unit with the SAU63X350TC, a direct alternative retaining the exact bore, stroke, output force, port size and SC-series TC mounting interface.
Because this SKU lacks a magnet, it cannot accept a sensing switch. The SAU upgrade introduces CMSG/DMSG/EMSG sensors for magnetized variants and a SAUF built-in 4M valve option the SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X350TC 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 SAU63X350TC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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 SU63X350TC Is Used
Package Diversion
Actuates routing gates on 3/8 inch powered lines, using the 1559 N thrust to push heavy cartons smoothly without overwhelming the TC mount.
Pallet Stops
Deploys a 350 mm stroke to halt incoming pallets at packing stations, relying on adjustable end cushions to decelerate the shifting mass.
Replacing the Airtac SU63-100 Standard Cylinder SU63X350TC with the SAU63X350TC
To replace the SU63X350TC, order the SAU63X350TC. Verify the 63 mm bore, 350 mm stroke, 3/8 inch port (default PT thread), M16x1.5 rod thread and TC mounting accessory are retained. If downsizing, a 50 mm bore yields 982 N push at 0.5 MPa; if upsizing, an 80 mm bore provides 2513 N. This non-magnetized SKU cannot support sensors, but if you need position detection on the SAU, specify the -S option and migrate from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. At 350 mm, prevent rod bending by using an external guide to absorb side loads. Note that a standard cylinder drifts on air loss; the cushions only decelerate, so fit an external rod lock or pilot-operated check valve for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAU63X350TC
- ✓ 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 SU63X350TC FAQ
Yes, the SU63X350TC is discontinued. The direct replacement is the AirTAC SAU63X350TC. It shares the identical 63 mm bore, 350 mm stroke, 1559 N force, 3/8 inch port and TC mounting, fitting the same application directly.
At 0.5 MPa it pushes 1559 N and pulls 1402 N. It pushes 2182 N at 0.7 MPa and 2805 N at 0.9 MPa, with a theoretical max of 318 kgf at 1.0 MPa. The cushions only decelerate; it cannot hold a load on air loss, so use an external rod lock or pilot-operated check valve.
