This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X285, 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 SU63X285
The AirTAC Airtac SU63-100 Standard Cylinder SU63X285 is a double-acting profile-type standard cylinder with a Ø63mm bore and 285mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X285, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X285
The AirTAC SU63X285 is a discontinued double-acting profile-type cylinder with a 63 mm bore and 285 mm stroke. It delivers 1559 N push and 1402 N pull at 0.5 MPa through a 3/8" port. AirTAC replaced this legacy unit with the SAU63X285, a direct sharing the exact bore, stroke, output force, port size, and SC-series mounting accessories.
Because it lacks the -S magnet option, this specific SKU cannot accept a position sensor. The SAU upgrade retains the compact extruded aluminum body—shorter than an equivalent ISO 15552 cylinder—but shifts sensing to the modern CMSG/DMSG/EMSG switch family, and introduces the SAUF valve-integrated variant the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X285 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 SAU63X285 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 SU63X285 Is Used
Package Diverting
Actuates routing gates on high-speed packaging lines, utilizing the 1559 N thrust to redirect heavy cartons reliably.
Pallet Stopping
Deploys as a pneumatic stop gate at roller conveyor ends, securely halting loaded pallets up to 79 kg in vertical lift setups.
Clamp Actuation
Drives medium-duty workholding clamps on machining fixtures, providing consistent 1402 N pull force for part retention.
Replacing the Airtac SU63-100 Standard Cylinder SU63X285 with the SAU63X285
To replace the SU63X285, order the SAU63X285 and verify your 3/8" port threads (PT, G, or NPT) alongside your SC-series mounting hardware (LB, FA, FB, CA, CB, or TC). Since this is a non-magnet SKU, it cannot support legacy CS1-B/DS1-B switches; if you need position detection on the SAU, you must add the -S option and migrate to CMSG/DMSG/EMSG sensors. For load holding, note that the 21 mm adjustable air cushions only decelerate the piston near stroke ends—they will not hold a load if air pressure drops. For vertical or suspended loads, install an external rod lock or pilot-operated check valve. With a 285 mm stroke, ensure adequate guiding to prevent rod bending under side loads. If you need more force, the 80 mm bore offers 2513 N push at 0.5 MPa; if less is acceptable, the 50 mm bore provides 982 N.
Replacement checklist
- ✓ Same bore / stroke → SAU63X285
- ✓ 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 SU63X285 FAQ
Yes, the AirTAC SU63X285 is discontinued and end-of-life. The direct replacement is the SAU63X285. It shares the identical 63 mm bore, 285 mm stroke, 3/8" port, output force, and SC-series mounting hardware, allowing a direct swap without mechanical modifications.
This double-acting cylinder pushes 1559 N and pulls 1402 N at 0.5 MPa, with a maximum theoretical force of 318 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept position switches; the SAU replacement with -S uses CMSG/DMSG/EMSG sensors.
