This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X375SH, 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 SU63X375SH
The AirTAC SU63-100 Standard Cylinder SU63X375SH is a double-acting profile-type standard cylinder with a Ø63mm bore and 375mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X375SH, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X375SH
The AirTAC SU63X375SH is a discontinued double-acting profile cylinder with a 63 mm bore and 375 mm stroke. Delivering 1559 N push force at 0.5 MPa, this extruded aluminium body is more compact than an ISO 15552 unit of the same size and shares AirTAC SC-series mounting. The direct replacement is the SAU63X375SH, matching the bore, stroke, output force, 3/8" port and accessories.
This -H variant specifies Viton FKM seals for 0-150 C high-temperature environments. The -S magnet supported legacy CS1-B/DS1-B switches, but the SAU replacement upgrades to CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X375SH 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 SAU63X375SH 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 SU63X375SH Is Used
Hot-End Part Ejection
Uses the Viton -H seal to withstand 150 C ambient heat near ovens while pushing 1559 N to eject moulded components.
Long-Reach Diversion
The 375 mm stroke actuates a diverter arm across a wide conveyor belt, requiring external guides to prevent rod bending.
Replacing the Airtac SU63-100 Standard Cylinder SU63X375SH with the SAU63X375SH
To replace this discontinued SU63X375SH, order the SAU63X375SH direct: it preserves the 63 mm bore, 375 mm stroke, M16x1.5 rod thread, 3/8" port, SC-series mounting and Viton -H high-temp seals. Because the -S magnet is present, note the sensor family changes from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches on the SAU. For sizing both ways, a neighbouring 50 mm bore yields 982 N push at 0.5 MPa, while an 80 mm bore provides 2513 N; this 63 mm bore gives 1559 N. At 375 mm stroke, prevent rod bending by using an external guide to absorb side loads. A plain cylinder drifts on air loss—the cushion only decelerates—so fit an external rod lock or pilot-operated check valve for held loads. If valve integration is needed, the SAU family offers the SAUF built-in 4M solenoid variant the SU line lacked.
Replacement checklist
- ✓ Same bore / stroke → SAU63X375SH
- ✓ 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 SU63X375SH FAQ
Yes, the AirTAC SU63X375SH is discontinued. The direct replacement is the SAU63X375SH. It matches the 63 mm bore, 375 mm stroke, 1559 N force, 3/8" port and SC-series mounting, while retaining the high-temp Viton seals. The only change is that the -S magnet now uses CMSG/DMSG/EMSG sensors instead of the older CS1-B/DS1-B switches.
This double-acting cylinder has a 3/8" air port. It generates 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, 2805 N push at 0.9 MPa, and a theoretical maximum of 318 kgf at 1.0 MPa. The 375 mm stroke requires external guides to prevent rod bending under side loads.
