This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ63X100-30SH, 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 SUJ63X100-30SH
The AirTAC Airtac SUJ Adjustable Cylinder SUJ63X100-30SH is a double-acting profile-type standard cylinder with a Ø63mm bore and 100mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ63X100-30SH, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ63X100-30SH
The AirTAC SUJ63X100-30SH is a double-acting double-rod profile cylinder with a 63mm bore and a 100mm nominal extend stroke. An external stop screw lets you trim the extend stroke by up to 30mm on-site, yielding a usable 70-100mm stroke window. The -H suffix specifies Viton/FKM seals for 0-150°C high-temperature environments, while the -S denotes a piston magnet for legacy CS1-B/DS1-B switches. This SUJ model is discontinued; the direct replacement is the SAUJ63X100-30SH, sharing the same bore, stroke, force, and SC-series FA/LB mounting.
The SAUJ upgrade transitions switch sensing to current CMSG/DMSG/EMSG sensors and introduces the SAUF built-in-valve variant. The stop screw sets the end position but is not a load lock; an external rod lock is required for held loads. The compact extruded aluminum barrel is shorter than ISO 15552 cylinders of the same bore.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ63X100-30SH 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 SAUJ63X100-30SH 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 SUJ63X100-30SH Is Used
Variable Depth Drilling
Trimming the extend stroke by up to 30mm on-site allows precise depth control for drilling operations without swapping cylinders when material thickness varies.
Adjustable Transfer Stops
Field-tuning the 70-100mm stroke window accommodates changing package sizes on a conveyor line, ensuring exact positioning at diverting stations.
Variable Height Indexing
The external stop screw provides repeatable end-of-stroke positioning for indexing lifts, allowing quick 30mm adjustments for different pallet heights.
Replacing the Airtac SUJ Adjustable Cylinder SUJ63X100-30SH with the SAUJ63X100-30SH
To replace the discontinued SUJ63X100-30SH, specify the SAUJ63X100-30SH direct: it preserves the 63mm bore, 100mm nominal stroke, 30mm adjust window, 3/8" port, and FA/LB mounting. The 30mm adjust window is ideal for field-tuning the 70-100mm extend stroke without machining. For the -S magnet, swap legacy CS1-B/DS1-B switches to CMSG/DMSG/EMSG sensors. For strokes of 300mm or longer, verify side-load guidance to prevent rod binding. The external stop screw defines end position only; use an external rod lock for load holding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ63X100-30SH
- ✓ 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 SUJ63X100-30SH FAQ
Yes, the SUJ63X100-30SH is discontinued. The direct replacement is the SAUJ63X100-30SH, which matches the 63mm bore, 100mm stroke, 30mm adjust window, 3/8" port, and FA/LB mounting. The SAUJ uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The 30mm adjust window allows shortening the 100mm nominal extend stroke down to 70mm on-site. The stop screw sets end position but is not a load lock.
