This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAU63X155, 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 SU63X155
The AirTAC Airtac SU63-100 Standard Cylinder SU63X155 is a double-acting profile-type standard cylinder with a Ø63mm bore and 155mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAU63X155, which matches its bore, stroke, force and mounting.

About the Airtac SU63-100 Standard Cylinder SU63X155
The AirTAC SU63X155 is a discontinued double-acting profile-type cylinder with a 63mm bore and 155mm stroke. It delivers 1559N of push force at 0.5MPa through a 3/8" port. The direct replacement is the SAU63X155, which preserves the exact bore, stroke, output force, port size, and SC-series mounting accessories.
This compact extruded-aluminum body is shorter than an ISO 15552 cylinder of the same bore. Because this SKU lacks a magnet, it cannot accept a sensor; furthermore, the SAU upgrade switches to CMSG/DMSG/EMSG switches and introduces a SAUF built-in-valve option the SU line never had.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAU63X155 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 SAU63X155 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 SU63X155 Is Used
Clamp Actuation
Provides 1559N of push force at 0.5MPa to securely hold heavy workpieces during CNC machining or welding operations.
Package Diversion
Uses the 155mm stroke to push medium-weight cartons off a main production line onto secondary packaging belts.
Replacing the Airtac SU63-100 Standard Cylinder SU63X155 with the SAU63X155
To replace this SU63X155, order the SAU63X155. Confirm your 3/8" port, M16x1.5 rod thread, and SC-series mounting (LB/FA/FB/CA/CB) are retained. Since this specific SKU has no magnet (-S), it cannot support a sensor; if you need position detection on the SAU, you must order an -S version and migrate to the current CMSG/DMSG/EMSG switch family. Sizing both ways: a 50mm bore gives 982N push at 0.5MPa, while an 80mm bore yields 2513N. A plain cylinder drifts on air loss—the 21mm adjustable cushions only decelerate near stroke end—so fit an external rod lock or pilot-operated check valve for held loads. The SAUF variant integrates a 4M solenoid valve if you need self-switching. At 155mm, side-load is minimal, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same bore / stroke → SAU63X155
- ✓ 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 SU63X155 FAQ
Yes, the SU63X155 is discontinued. The direct replacement is the AirTAC SAU63X155. It offers identical 63mm bore, 155mm stroke, 318kgf max force, 3/8" port, and SC-series mounting compatibility. You can install it without modifying your existing framework.
At 0.5MPa it pushes 1559N and pulls 1402N. Push force is 2182N at 0.7MPa and 2805N at 0.9MPa, with a theoretical max of 318kgf at 1.0MPa. This specific SKU has no magnet, so it cannot accept a sensor. If you need sensing on the SAU replacement, you must order an -S model and use CMSG/DMSG/EMSG switches instead of the legacy CS1-B/DS1-B.
