This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAUJ100X275-10S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAUJ100X275-10S 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 SUJ100X275-10S
The AirTAC Airtac SUJ Adjustable Cylinder SUJ100X275-10S is a double-acting profile-type standard cylinder with a Ø100mm bore and 275mm stroke, 1/2" air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAUJ100X275-10S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ100X275-10S
The AirTAC SUJ100X275-10S is a double-acting single-rod adjustable-stroke profile cylinder, now discontinued and replaced by the SAUJ100X275-10S. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, giving a usable 265-275 mm stroke out of the 275 mm maximum. The 100 mm bore delivers 3927 N push and 3681 N pull at 0.5 MPa, rising to 7068 N push at 0.9 MPa. This compact profile barrel is shorter than an ISO 15552 cylinder of the same bore.
The drop-in SAUJ100X275-10S retains the exact bore, stroke, 1/2" port, M20x1.5 rod thread, and FA/LB mounting. For your sizing, a safe working load is roughly 2356 N (60% of the 0.5 MPa push), translating to a 200 kg vertical lift with a 2:1 margin. The stop screw sets end position but is not a load lock; use an external rod lock for held loads. The -S magnet on this unit worked with legacy CS1-B/DS1-B switches, whereas the SAUJ upgrade uses current CMSG/DMSG/EMSG sensors.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ100X275-10S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAUJ100X275-10S 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.
Model Code: Airtac SUJ Adjustable Cylinder SUJ100X275-10S
| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 100 | Bore size in mm. |
| ×275 | Stroke length in mm. |
| -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 SUJ100X275-10S Is Used
Press Fit Tuning
Trimming the extend stroke by up to 10 mm on-site allows precise positioning for press-fit operations without machining hard stops.
Divertor Adjustment
Field-tuning the extend end position lets operators adjust divertor strokes on packaging lines for varying product sizes.
Pallet Stop Calibration
The external stop screw provides a 265-275 mm usable stroke to calibrate pallet stops precisely on the fly.
Replacing the Airtac SUJ Adjustable Cylinder SUJ100X275-10S with the SAUJ100X275-10S
To replace this discontinued SUJ100X275-10S, order the drop-in SAUJ100X275-10S, matching the 100 mm bore, 275 mm max stroke, 10 mm adjust window, and FA/LB SC-series mounting. When sizing both ways, the neighbouring 80 mm bore yields 2513 N push at 0.5 MPa, while this 100 mm bore provides 3927 N. Choose the 10 mm adjust window if you need precise field tuning of the extend end-position. Note the -S sensor change: legacy CS1-B/DS1-B switches are replaced by CMSG/DMSG/EMSG sensors on the SAUJ. For this 275 mm stroke, verify side-load limits on the rod end. The stop screw decelerates the piston but does not lock the load without live air.
Replacement checklist
- ✓ Same bore / stroke → SAUJ100X275-10S
- ✓ 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 SUJ100X275-10S FAQ
Yes, the SUJ100X275-10S is discontinued. The exact drop-in replacement is the SAUJ100X275-10S, sharing the same 100 mm bore, 275 mm stroke, 10 mm adjust window, 1/2" port, and FA/LB mounting. You must upgrade the -S sensors from legacy CS1-B/DS1-B to current CMSG/DMSG/EMSG switches.
The 100 mm bore provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and 7068 N push at 0.9 MPa. The external stop screw window is 10 mm, allowing you to shorten the 275 mm nominal extend stroke down to 265 mm. The stop sets end position and is not a load lock.
