This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ63X200-100S, 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 SUJ63X200-100S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ63X200-100S is a double-acting profile-type standard cylinder with a Ø63mm bore and 200mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ63X200-100S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ63X200-100S
The AirTAC SUJ63X200-100S is a discontinued 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 100-200 mm extend window from the 200 mm nominal maximum. It features a 20 mm rod, M16x1.5 rod thread, and a 3/8" port.
As this unit is end-of-life, the direct replacement is the SAUJ63X200-100S, which preserves the bore, stroke, force, and SC-series FA/LB mounting compatibility. The SAUJ upgrade transitions from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors. Note the stop screw sets end position only; it is not a load lock.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ63X200-100S 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 SAUJ63X200-100S 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 SUJ Adjustable Cylinder SUJ63X200-100S Is Used
Variable Pitch Forming
Bending or pressing operations where the extend endpoint must be fine-tuned on-site for different material thicknesses without swapping the entire actuator.
Adjustable Diverter Gates
Routing packages of varying sizes on a line by trimming the extend stroke up to 100 mm to reposition the diverting jaw accurately.
Variable Depth Sealing
Heat-sealing or crimping cartons of different depths using the 100 mm adjust window to set the precise extend position per batch.
Replacing the Airtac SUJ Adjustable Cylinder SUJ63X200-100S with the SAUJ63X200-100S
To replace the SUJ63X200-100S, order the direct replacement SAUJ63X200-100S, ensuring you update your sensing to CMSG/DMSG/EMSG switches if migrating from legacy CS1-B/DS1-B units. The 100 mm adjust window is ideal if your extend endpoint requires field tuning between 100 mm and 200 mm. Retain FA or LB mounts from the SC series. For strokes of 300 mm or longer, carefully verify side-load limits to prevent guide wear. Remember, the stop screw dictates end position but does not lock the load—specify an external rod lock for held loads.
Replacement checklist
- ✓ Same bore / stroke → SAUJ63X200-100S
- ✓ 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 SUJ63X200-100S FAQ
Yes, the SUJ63X200-100S is discontinued. The direct replacement is the SAUJ63X200-100S, which matches the 63 mm bore, 200 mm stroke, 3/8" port, and FA/LB mounting. You must upgrade sensing from legacy CS1-B/DS1-B switches to current CMSG/DMSG/EMSG sensors.
The external stop screw provides a 100 mm adjust window, allowing the extend stroke to be shortened from the 200 mm nominal maximum down to 100 mm on-site.
