This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X175N, 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 SU80X175N
The AirTAC SU63-100 Standard Cylinder SU80X175N is a double-acting profile-type standard cylinder with a Ø80mm bore and 175mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X175N, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X175N
The AirTAC SU80X175N is a discontinued double-acting profile-type cylinder with an 80 mm bore and 175 mm stroke. It delivers 2513 N push and 2268 N pull at 0.5 MPa, operating through a fixed 3/8" port. AirTAC replaced this end-of-line unit with the SAU80X175N, a direct upgrade retaining the exact bore, stroke, force, port size, and SC-series mounting.
Because this SKU lacks a magnet, it cannot accept a position switch. The SAU upgrade enables modern CMSG/DMSG/EMSG sensors on magnetised variants, plus a SAUF valve-integrated option the SU line never offered. The NBR seal suits -20 to +70 C; cushions only decelerate, so add a rod lock for holding.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAU80X175N 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 SU80X175N Is Used
Pallet Stopping
Halts loaded pallets at 175 mm stroke, relying on the 28 mm adjustable air cushions to absorb kinetic energy.
Press Ejection
Ejects formed parts from machinery, taking advantage of the 2268 N pull force at 0.5 MPa for reliable retraction.
Replacing the Airtac SU63-100 Standard Cylinder SU80X175N with the SAU80X175N
To replace this SU80X175N, order the SAU80X175N direct equivalent, verifying the 80 mm bore, 175 mm stroke, 3/8" port, M20x1.5 rod thread, and SC-series mounting hardware. This non-magnetic SKU cannot support sensors; if detection is needed, specify an -S SAU model and migrate from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches. The NBR seal handles standard -20 to +70 C temperatures, with Viton H available for up to 150 C. For force context, stepping down to a 63 mm bore yields 1559 N push at 0.5 MPa, while stepping up to 100 mm provides 3927 N. A plain cylinder drifts without live air, so fit an external pilot-operated check valve for load holding. At 175 mm, side-load stress is minimal, but always guide the load to prevent rod bending.
Replacement checklist
- ✓ Same bore / stroke → SAU80X175N
- ✓ 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 SU80X175N FAQ
Yes, the SU80X175N is discontinued. The direct replacement is the AirTAC SAU80X175N. It shares the identical 80 mm bore, 175 mm stroke, 2513 N push force at 0.5 MPa, 3/8" port, and SC-series mounting, so it fits the same application directly.
At 0.5 MPa it provides 2513 N push and 2268 N pull; at 0.7 MPa push is 3518 N, and the theoretical maximum is 513 kgf at 1.0 MPa. Because this specific SKU lacks a magnet, it cannot accept a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches on its -S variants.
