This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ63X200-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ63X200-75 in place of this model. 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 SUJ63X200-75
The AirTAC Airtac SUJ Adjustable Cylinder SUJ63X200-75 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 drop-in replacement is the SAUJ63X200-75, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ63X200-75
The AirTAC SUJ63X200-75 is a double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 125-200 mm extension from the 200 mm nominal maximum. This bore delivers 1559 N push and 1402 N pull at 0.5 MPa, rising to 2805 N push at 0.9 MPa, and features a 3/8" port with a 20 mm rod. The stop screw sets the end position but is not a load lock; loads drift without live air.
This SUJ63X200-75 model is discontinued and the exact drop-in replacement is the SAUJ63X200-75, retaining the same bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrades sensing to current CMSG/DMSG/EMSG switches, whereas this legacy unit used CS1-B/DS1-B. Note this non-magnet SKU cannot accept switches. For sizing, a safe working load is ~935 N (60% of the 0.5 MPa push), equating to a ~79 kg vertical lift with a 2:1 margin.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ63X200-75 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 SAUJ63X200-75 produces the same force from the same bore — a true drop-in on output. 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 SUJ63X200-75 Is Used
Variable Pitch Indexing
Allows on-site extend stroke tuning up to 75 mm to alter part pitch without swapping cylinders when product formats change.
Adjustable Transfer Stops
Sets precise reject or diversion positions on a line, trimming the 200 mm stroke to match varying package widths.
Variable Depth Pushers
Adjusts the extend endpoint on-site to push different carton depths into packing zones without reprogramming controls.
Replacing the Airtac SUJ Adjustable Cylinder SUJ63X200-75 with the SAUJ63X200-75
To replace the discontinued SUJ63X200-75, use the drop-in SAUJ63X200-75 which preserves the 63 mm bore, 200 mm stroke, 75 mm adjust window, 3/8" port, and FA/LB mounting. When sizing both ways, the neighboring 50 mm bore provides 982 N push at 0.5 MPa, while the 80 mm bore offers 2513 N push at 0.5 MPa. Choose the 75 mm adjust window if you need to trim the extend stroke on-site by up to 75 mm; the stop screw sets end position but is not a lock. Because this non-magnet SKU lacks a piston magnet, it cannot accept switches, unlike the -S SAUJ which uses CMSG/DMSG/EMSG sensors. For stroke lengths of 300 mm or more, verify side-load limits to prevent excessive rod bearing wear. For held loads, add an external rod lock or pilot-operated check valve, as air cushions only decelerate and the piston drifts without live air.
Replacement checklist
- ✓ Same bore / stroke → SAUJ63X200-75
- ✓ 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 SUJ63X200-75 FAQ
Yes, the SUJ63X200-75 is discontinued. The exact drop-in replacement is the SAUJ63X200-75, which matches the 63 mm bore, 200 mm stroke, 75 mm 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 63 mm bore provides 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push at 0.7 MPa, and 2805 N push at 0.9 MPa. The external stop screw window is 75 mm, allowing you to trim the 200 mm nominal extend stroke down to 125 mm on-site. The stop sets end position but is not a load lock.
