This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X50H, 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 SU80X50H
The AirTAC SU63-100 Standard Cylinder SU80X50H is a double-acting profile-type standard cylinder with a Ø80mm bore and 50mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X50H, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X50H
The AirTAC SU80X50H is a discontinued double-acting profile cylinder featuring an extruded aluminum barrel and a high-temperature Viton H seal rated for 0 to 150 C. It delivers 2513 N push force at 0.5 MPa through an 80 mm bore. AirTAC replaced this end-of-life unit with the SAU80X50H, a direct replacement retaining the exact 50 mm stroke, 3/8 inch port, M20x1.5 rod thread, and SC-series mounting footprint.
Because this SKU lacks a magnet, it cannot accept a sensing switch. The SAU upgrade also introduces the SAUF variant with a built-in 4M solenoid valve, an option the original SU line never offered.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X50H carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAU80X50H 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 SU80X50H Is Used
High-Temperature Ejection
Ideal for pushing molded parts out of hot zones using the Viton H seal rated up to 150 C, providing 2513 N of thrust at 0.5 MPa.
Short-Stroke Clamping
Secures heavy workpieces in automated machining fixtures where a compact 50 mm stroke and 80 mm bore deliver reliable holding against vibration.
Replacing the Airtac SU63-100 Standard Cylinder SU80X50H with the SAU80X50H
To replace this discontinued SU80X50H, order the SAU80X50H direct equivalent, verifying the 80 mm bore, 50 mm stroke, 3/8 inch port, M20x1.5 rod thread, and high-temperature Viton H seal. If downsizing, a 63 mm bore yields 1559 N push at 0.5 MPa; if upsizing, a 100 mm bore provides 3927 N. Note that this non-magnetic SKU cannot support sensors, whereas the SAU family accommodates modern CMSG/DMSG/EMSG switches on magnetized variants. The SAUF model adds a self-switching built-in valve if automation simplification is desired. Remember that a standard cylinder drifts without live air—the 28 mm adjustable cushion only decelerates the piston, so install an external rod lock or pilot-operated check valve for secure load holding.
Replacement checklist
- ✓ Same bore / stroke → SAU80X50H
- ✓ 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 SU80X50H FAQ
Yes, the SU80X50H is discontinued. The direct replacement is the AirTAC SAU80X50H. It matches the original 80 mm bore, 50 mm stroke, 2513 N force, 3/8 inch port, Viton H seal, and SC-series mounting accessories perfectly.
At 0.5 MPa it pushes 2513 N and pulls 2268 N. Push force is 3518 N at 0.7 MPa and 4523 N at 0.9 MPa, with a theoretical max of 513 kgf at 1.0 MPa. The 28 mm air cushions only decelerate the piston near stroke end; the cylinder will drift without live air, so use an external rod lock for load holding.
