This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ63X220-100S, 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 SUJ Adjustable Cylinder SUJ63X220-100S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ63X220-100S is a double-acting profile-type standard cylinder with a Ø63mm bore and 220mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ63X220-100S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ63X220-100S
The AirTAC SUJ63X220-100S is a double-acting, double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 120-220 mm window from the 220 mm nominal maximum. It features a 63 mm bore, a 20 mm rod, M16x1.5 rod threads, adjustable 21 mm cushions, and a 3/8" port. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.
The direct replacement is the SAUJ63X220-100S, matching the bore, stroke, force, port, and FA/LB mounting. Because this -S model has a piston magnet, it used legacy CS1-B/DS1-B sensors, whereas the SAUJ upgrade accepts current CMSG/DMSG/EMSG switches. The compact profile barrel is shorter than an ISO 15552 cylinder of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ63X220-100S 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 SAUJ63X220-100S 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.
Where the Airtac SUJ Adjustable Cylinder SUJ63X220-100S Is Used
Variable Depth Boring
Machine tools needing field stroke tuning to bore precise depths between 120 and 220 mm without swapping the entire cylinder.
Adjustable Flap Folding
Packaging lines that require on-site extend stroke trimming to handle variable carton sizes on the fly.
Variable Position Diverter
Conveyor sorting gates where the actuator must tune its push distance to divert differing product widths accurately.
Replacing the Airtac SUJ Adjustable Cylinder SUJ63X220-100S with the SAUJ63X220-100S
To replace the discontinued SUJ63X220-100S, order the direct replacement SAUJ63X220-100S, which preserves the 3/8" port, 220 mm nominal stroke, 100 mm adjust window, and FA/LB mounting. Select the 100 mm adjust window when you need on-site extend flexibility from 120 to 220 mm. Note the sensor change: this -S model used CS1-B/DS1-B switches, but the SAUJ uses CMSG/DMSG/EMSG sensors. For this 220 mm stroke, verify side-load limits to prevent rod bearing wear. The external stop sets end position but does not lock the load; add an external rod lock for holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ63X220-100S
- ✓ 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 SUJ Adjustable Cylinder SUJ63X220-100S FAQ
Yes, the SUJ63X220-100S is discontinued. The direct replacement is the SAUJ63X220-100S, which matches the 63 mm bore, 220 mm stroke, 100 mm adjust window, 3/8" port, and FA/LB mounting. The SAUJ also accepts current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw provides a 100 mm adjust window, allowing you to shorten the extend stroke from the 220 mm nominal maximum down to 120 mm on-site. The stop sets end position and is not a load lock.
