This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ80X50-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ80X50-10 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 SUJ80X50-10
The AirTAC Airtac SUJ Adjustable Cylinder SUJ80X50-10 is a double-acting profile-type standard cylinder with a Ø80mm bore and 50mm stroke, 3/8" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ80X50-10, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ80X50-10
The AirTAC SUJ80X50-10 is a double-acting, single-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 40-50 mm stroke from the 50 mm nominal maximum. The extruded aluminum profile barrel is notably shorter than a standard cylinder of the same bore. This specific SKU is DISCONTINUED; the exact drop-in replacement is the SAUJ80X50-10, matching the 80 mm bore, 2513 N push force at 0.5 MPa, and 3/8" port.
At 0.5 MPa it delivers 2513 N push and 2268 N pull, translating to a safe working load of roughly 1508 N (60% of push) or a 128 kg vertical lift with a 2:1 margin. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads. Because this SKU lacks a magnet (-S), it cannot take a magnetic switch, and the SAUJ upgrade shifts sensing from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ80X50-10 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAUJ80X50-10 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 SUJ80X50-10 Is Used
Press Fit Tuning
Dialing in a delicate press fit by trimming the extend stroke up to 10 mm on-site, ensuring a 40-50 mm insertion depth without re-machining hard stops.
Transfer Diverter
Adjusting a diverter gate position on a packaging line to handle varying carton lengths, using the external stop screw to set the exact 40-50 mm extend endpoint.
Pallet Stopper
Fine-tuning a pneumatic pallet stop position on a roller conveyor by shortening the extend stroke up to 10 mm to accommodate different pallet footprints.
Replacing the Airtac SUJ Adjustable Cylinder SUJ80X50-10 with the SAUJ80X50-10
To replace the discontinued SUJ80X50-10, order the drop-in SAUJ80X50-10, which preserves the 80 mm bore, 50 mm nominal stroke, 10 mm adjust window, 3/8" port, and FA/LB mounting. When sizing both ways, the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. Select the 10 mm adjust window if you need precise 40-50 mm extend tuning on-site. Note that this non-magnetic SKU cannot accept sensors; the SAUJ requires CMSG/DMSG/EMSG switches instead of legacy CS1-B/DS1-B. For strokes at or above 300 mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same bore / stroke → SAUJ80X50-10
- ✓ 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 SUJ80X50-10 FAQ
Yes, the SUJ80X50-10 is discontinued. The exact drop-in replacement is the SAUJ80X50-10, which matches the 80 mm bore, 50 mm stroke, 10 mm adjust window, 3/8" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B.
The 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a theoretical max of 513 kgf at 1.0 MPa. The external stop screw provides a 10 mm adjust window, meaning you can shorten the 50 mm nominal extend stroke down to 40 mm on-site. The stop sets end position but is not a load lock.
