This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X175SH, 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 SU63X175SH
The AirTAC SU63-100 Standard Cylinder SU63X175SH is a double-acting profile-type standard cylinder with a Ø63mm bore and 175mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X175SH, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X175SH
The AirTAC SU63X175SH is a discontinued double-acting profile-type cylinder with a 63 mm bore and 175 mm stroke. It features an extruded aluminum barrel and adjustable air cushions at both ends, making it more compact than an ISO 15552 cylinder of the same bore. It delivers a push force of 1559 N at 0.5 MPa and uses a 3/8" port. The direct replacement is the SAU63X175SH, which matches the bore, stroke, force, port, and SC-series mounting.
The -H suffix indicates high-temperature Viton seals, extending the operating range from -20 to +150 C. The -S magnet on this legacy model worked with CS1-B/DS1-B switches; the SAU replacement upgrades to CMSG/DMSG/EMSG sensors, and the SAU line also introduces a SAUF variant with a built-in 4M solenoid valve.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X175SH 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 SAU63X175SH 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 SU63X175SH Is Used
Hot-End Part Ejection
Utilizes the 1559 N push force and Viton high-temp seals to eject molded components from heated environments up to 150 C without seal degradation.
Heavy Transfer Diversion
Deploys the 175 mm stroke to push heavy pallets or workpieces off a main conveyor line, absorbing end-of-stroke impact with adjustable cushions.
Vertical Lift Gates
Lifts access doors or material bins up to 79 kg safely, relying on the 63 mm bore profile body to minimize space requirements on the frame.
Replacing the Airtac SU63-100 Standard Cylinder SU63X175SH with the SAU63X175SH
To replace this SU63X175SH, order the SAU63X175SH. Verify the 63 mm bore, 175 mm stroke, 3/8" port, M16x1.5 rod thread, and SC-series mounting hardware are identical. Because this SKU includes the -S magnet, note the sensor family changes from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches on the SAU. The -H high-temp Viton seal (0-150 C) must also be specified on the new order. For sizing alternatives, dropping to a 50 mm bore reduces push force to 982 N at 0.5 MPa, while stepping up to an 80 mm bore increases it to 2513 N. A plain cylinder does not hold load without live air; the cushions only decelerate, so use an external rod lock or pilot-operated check valve for secure holding. At 175 mm stroke, side-load and rod-bending are minimal, but ensure adequate guidance. If valve integration is desired, the SAU family offers the SAUF variant with a built-in 4M valve.
Replacement checklist
- ✓ Same bore / stroke → SAU63X175SH
- ✓ 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 SU63X175SH FAQ
Yes, the SU63X175SH is discontinued. The direct replacement is the SAU63X175SH. It shares the same 63 mm bore, 175 mm stroke, 3/8" port, output force, and SC-series mounting, but the -S magnet sensor family changes from CS1-B/DS1-B to CMSG/DMSG/EMSG.
The 63 mm bore uses a 3/8" port. It generates a push force of 1559 N and pull of 1402 N 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. Operating speed is 30-800 mm/s.
