This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X80SH, 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 SU63X80SH
The AirTAC SU63-100 Standard Cylinder SU63X80SH is a double-acting profile-type standard cylinder with a Ø63mm bore and 80mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X80SH, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X80SH
The AirTAC SU63X80SH is a discontinued double-acting profile-type cylinder with an 80 mm stroke and a 63 mm bore. It delivers 1559 N push and 1402 N pull at 0.5 MPa, utilizing a 3/8" port and a 20 mm piston rod. AirTAC replaced this end-of-line unit with the SAU63X80SH, a direct upgrade retaining the exact bore, stroke, output force, port size, and SC-series mounting compatibility.
This -H variant specifies Viton FKM seals for 0-150 C high-temperature environments. The -S magnet on this legacy cylinder paired with CS1-B/DS1-B switches, whereas the SAU replacement uses modern CMSG/DMSG/EMSG sensors. Note that a standard cylinder drifts without live air; use an external rod lock for secure load holding.

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 SAU63X80SH 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 SU63X80SH Is Used
Hot-End Forming
Ideal for plastic or rubber molding presses where the Viton -H seal withstands 150 C ambient heat while delivering 1559 N of clamping force.
Diverting Heavy Goods
Provides robust 80 mm actuation to push heavy pallets or metal components across transfer lines at 30-800 mm/s operating speeds.
High-Temp Ejection
Suits automated ejection of freshly machined or heated parts from fixtures, utilizing the 63 mm bore's 1402 N pull force safely.
Replacing the Airtac SU63-100 Standard Cylinder SU63X80SH with the SAU63X80SH
To replace the SU63X80SH, order the SAU63X80SH, confirming the 63 mm bore, 80 mm stroke, 3/8" port, M16x1.5 rod thread, and SC-series mounting. Because this SKU includes a magnet (-S), you must upgrade to CMSG/DMSG/EMSG sensors as the legacy CS1-B/DS1-B switches are obsolete. The -H seal provides 0-150 C heat resistance. When sizing, neighbouring bores (50 mm or 80 mm) offer 982 N or 2513 N push at 0.5 MPa respectively. A plain cylinder does not hold loads without live air; add a pilot-operated check valve for vertical applications. The SAUF variant adds a built-in 4M solenoid valve if self-switching is needed.
Replacement checklist
- ✓ Same bore / stroke → SAU63X80SH
- ✓ 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 SU63X80SH FAQ
Yes, the SU63X80SH is discontinued. The direct replacement is the AirTAC SAU63X80SH. It matches the 63 mm bore, 80 mm stroke, 3/8" port, force, and SC-series mounting, but the -S magnet now requires CMSG/DMSG/EMSG sensors instead of the old CS1-B/DS1-B switches.
At 0.5 MPa it pushes 1559 N and pulls 1402 N. Push force is 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 -H Viton seal allows 0-150 C operation. The 3/8" port cylinder runs 30-800 mm/s, and cushions only decelerate; they do not hold loads.
