About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X150SU
The AirTAC MBL25X150SU is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a push force of 245 N and a pull force of 206 N at 0.5 MPa, making it well-suited for 150 mm linear positioning tasks in small-part automation. The riveted rolling-packed barrel keeps the body light and small, but unlike a tie-rod cylinder, it is not designed to be disassembled for field rebuilding.
This specific SKU includes a U flat-end back cover for rigid fixed-foot mounting and an -S built-in magnet for position detection. The magnet works seamlessly with AirTAC CMSG reed switches or DMSG and EMSG electronic sensors. The carbon-steel piston rod features a 20 um hard-chrome plating for excellent wear and corrosion resistance, while the heterogeneous two-way piston seal retains grease for a long service life. A fixed rubber bumper on the base softens end-of-stroke impact, though it is not an adjustable air cushion like the MBLC variant.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X150SU Is Used
PCB Shuttle Ejection
Provides 245 N of push at 0.5 MPa to eject populated printed circuit boards from an SMT pick-and-place shuttle without stressing the delicate vacuum nozzles.
Pharmaceutical Pouch Folding
Uses the 150 mm stroke and built-in magnet to confirm the end position of a sealing jaw that folds and presses small pharmaceutical foil pouches.
Spindle Collet Actuation
Fits within the tight housing of a benchtop lathe to actuate the collet opener, using the 206 N pull force to release small brass bar stock.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X150SU the Right Cylinder?
At 0.5 MPa, this 25 mm bore generates 245 N of push force. If your mechanism requires less force, step down to the 20 mm bore, which provides 157 N of push. If you need to move heavier loads, step up to the 32 mm bore, which yields 402 N of push. Because this is a double-acting cylinder, air drives the rod in both directions; if you only need a spring-return push or pull, consider the single-acting MSBL or MTBL models instead.
With a 150 mm stroke, the Ø10 mm rod is susceptible to bending under side loads. For unsupported lengths of this scale, use an external guide rail, select the MBLD double-rod cylinder for anti-rotation, or pivot to a CA back cover to allow angular alignment. Note that the fixed rubber bumper only softens end impact; it does not hold the load. If the rod must remain in place when air pressure is lost or the valve is centered, add an external rod lock or a pilot-operated check valve. This exact replacement matches: 25 mm bore, 150 mm stroke, G1/8 port, PT thread, U flat-end cover, and an -S magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB / FA / SDB) and back cover (CA pivot / U flat-end).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBL Aluminum Alloy Mini Cylinder MBL25X150SU FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N of push force and 206 N of pull force. If you operate at 0.7 MPa, the push force increases to 343 N. The maximum theoretical force is 50 kgf when running at the 1.0 MPa pressure limit.
Yes, the -S suffix means this model has a built-in magnet designed to work with AirTAC CMSG reed switches, as well as DMSG and EMSG electronic solid-state sensors. For cushioning, the base MBL relies on a fixed rubber bumper to soften end-of-stroke impact; it does not have an adjustable air cushion screw (you would need the MBLC variant for that).
