This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU80X5, 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 SU80X5
The AirTAC Airtac SU63-100 Standard Cylinder SU80X5 is a double-acting profile-type standard cylinder with a Ø80mm bore and 5mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU80X5, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU80X5
The AirTAC SU80X5 is a discontinued double-acting profile-type cylinder with an 80 mm bore and 5 mm stroke. It delivers 2513 N push force at 0.5 MPa through a 3/8" port. The direct replacement is the SAU80X5, matching the body, stroke, force, port and SC-series mounting.
This non-magnetic SKU cannot accept a sensor, whereas the SAU upgrade supports CMSG/DMSG/EMSG switches and a SAUF built-in-valve variant.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU80X5 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 SAU80X5 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 SU80X5 Is Used
Short-Stroke Clamping
Ideal for high-force brief clamping actions in machining fixtures, utilizing the 80 mm bore thrust within a tight 5 mm travel.
Heavy Ejector Pins
Provides robust 2513 N push force at 0.5 MPa to positively eject dense molded parts or stampings from stationary tooling.
Brake Actuation
Suits heavy-duty holding brake mechanisms where a compact profile body and immediate high-force output are required.
Replacing the Airtac SU63-100 Standard Cylinder SU80X5 with the SAU80X5
To replace this discontinued SU80X5, order the SAU80X5 direct equivalent, verifying the 80 mm bore, 5 mm stroke, 3/8" port, M20x1.5 rod thread and SC-series mounting. Because this specific SKU lacks a magnet (-S), it cannot hold a magnetic switch; the SAU family uses CMSG/DMSG/EMSG sensors. For sizing both ways, a 63 mm bore offers 1559 N push at 0.5 MPa, while a 100 mm bore provides 3927 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock for held loads. The SAUF valve-integrated option is available if needed.
Replacement checklist
- ✓ Same bore / stroke → SAU80X5
- ✓ 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 SU80X5 FAQ
Yes, the SU80X5 is discontinued. The direct replacement is the AirTAC SAU80X5, which retains the exact 80 mm bore, 5 mm stroke, 2513 N force, 3/8" port and SC-series mounting.
It delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a max of 513 kgf at 1.0 MPa. This non-S SKU cannot take a sensor; the SAU replacement uses CMSG/DMSG/EMSG switches.
