This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X485, 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.

The AirTAC SU63-100 Standard Cylinder SU63X485 is a double-acting profile-type standard cylinder with a Ø63mm bore and 485mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X485, which matches its bore, stroke, force and mounting.
The AirTAC SU63X485 is a discontinued double-acting profile-type cylinder with a 63 mm bore and 485 mm stroke. Delivering 1559 N push force at 0.5 MPa, it uses an extruded aluminum barrel that is more compact than an ISO 15552 cylinder of the same bore. AirTAC replaced this unit with the SAU63X485, a direct replacement retaining the exact body dimensions, 3/8" port, M16x1.5 rod thread, and SC-series mounting.
Because this SKU lacks a magnet, it cannot accept a sensor. If sensing is needed on the SAU upgrade, the new CMSG/DMSG/EMSG switches are required instead of the legacy CS1-B/DS1-B. The SAU line also introduces the SAUF variant with a built-in 4M solenoid valve.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X485 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| Max (@1.0 MPa) | 318 kgf | |
The SAU63X485 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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.
Pushes medium-weight packages off a sorting line using 1559 N of thrust at 0.5 MPa, with the 485 mm stroke reaching across the belt.
Acts as a physical stop for pallets entering a wrap station, handling the impact while the adjustable cushions decelerate the load.
Extends to clamp large workpieces in machining fixtures, providing up to 318 kgf maximum theoretical force at 1.0 MPa.
To replace the SU63X485, order the SAU63X485 and confirm the 3/8" port, M16x1.5 rod thread, PT/G/NPT thread standard, and SC-series mounting (LB/FA/FB/CA/CB). This non-magnetic SKU cannot take a switch; if you need sensing on the SAU, plan for the CMSG/DMSG/EMSG family. For load holding, note that a plain cylinder drifts on air loss—the 21 mm cushions only decelerate—so add an external rod lock or pilot-operated check valve. With a 485 mm stroke, prevent side-load and rod-bending by using an external guide. Sizing both ways: a 50 mm bore gives 982 N push at 0.5 MPa, while an 80 mm bore yields 2513 N.
Replacement checklist
Yes, the SU63X485 is discontinued. The direct replacement is the AirTAC SAU63X485. It shares the identical 63 mm bore, 485 mm stroke, output force, 3/8" port, and SC-series mounting accessories, so it fits the same application without modification.
At 0.5 MPa it provides 1559 N push and 1402 N pull; at 0.7 MPa it pushes 2182 N, with a 318 kgf maximum at 1.0 MPa. This specific SKU has no magnet and cannot take a sensor. The SAU replacement supports CMSG/DMSG/EMSG switches, unlike the older CS1-B/DS1-B.
Send us the quantity and destination. We confirm price, stock and lead time on the SAU63X485 replacement — usually within 7-8 hours.
