About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X300SCA
The AirTAC MBL25X300SCA is a double-acting aluminum mini round cylinder engineered for tight machine spaces where a larger profile body will not fit. It delivers a 245 N push force at 0.5 MPa over a 300 mm stroke. The riveted rolling-packed barrel crimps the front and rear covers directly to the tube, yielding a lightweight, compact body that is not designed to be disassembled like a traditional tie-rod cylinder.
This specific SKU includes a built-in magnet (-S) for compatibility with AirTAC CMSG reed and DMSG or EMSG solid-state sensor switches to track rod position. It also features a CA pivot back cover, allowing the cylinder to swing on a pin to accommodate arcing or angular loads. The carbon-steel piston rod features a 20 µm hard-chrome plating for wear resistance, paired with a heterogeneous two-way piston seal that retains grease for a long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X300SCA Is Used
Textile Loom Weft Guide
Uses the 245 N push force and CA pivot mount to smoothly swing and thread weft yarn carriers across a 300 mm arc during high-speed weaving operations.
Packaging Flap Folder
Relies on the 300 mm stroke to extend and fold corrugated carton side flaps, with the built-in magnet triggering a DMSG sensor to confirm fold completion.
Bottling Line Diverter
Pushes glass bottles onto a secondary processing lane using 206 N of pull force, while the compact aluminum body fits within the narrow conveyor frame gaps.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X300SCA the Right Cylinder?
Providing 245 N of push force at 0.5 MPa, stepping down to the 20 mm bore drops the output to 157 N, while stepping up to the 32 mm bore increases it to 402 N. The base MBL relies on a fixed rubber bumper to soften end-of-stroke impacts; if your 300 mm move carries a heavy load at high speed, choose the MBLC variant for its adjustable air cushion. Note that this cylinder cannot hold a load if air pressure is lost or exhausted, as the rod will drift without live pressure or an external pilot-operated check valve.
With a 300 mm stroke on a Ø10 mm rod, side-load tolerance is low; the unsupported rod is highly susceptible to bending under lateral forces. The CA pivot back cover on this exact unit helps mitigate angular stress by allowing the body to swing, but you should still use an external guide or consider the MBLD double-rod type for strict anti-rotation needs. Replacement match: 25 mm bore, 300 mm stroke, G1/8 port, PT thread, CA back cover, magnet enabled.
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 MBL25X300SCA FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N of push force and 206 N of pull force. At 0.7 MPa, the push force reaches 343 N, with a maximum theoretical force of 50 kgf at 1.0 MPa. The operational speed ranges from 30-800 mm/s.
No, the base MBL uses a fixed rubber bumper to absorb end-of-stroke impact and is not adjustable. If your application requires adjustable air cushioning to handle heavier moving masses, you must select the MBLC variant instead.
