About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X250SU
The AirTAC MBL25X250SU is a double-acting aluminum mini round cylinder engineered for tight assembly spaces. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa, making it suitable for moving small jigs over a 250 mm travel. A built-in magnet (-S) allows CMSG reed or DMSG and EMSG solid-state sensor switches to track rod position for end-of-stroke confirmation.
This 25 mm bore unit features a Ø10 mm carbon steel rod with 20 µm hard chrome plating to resist wear and corrosion. The riveted rolling-packed barrel keeps the overall footprint small and lightweight, though it is not designed to be disassembled like a tie-rod cylinder. The U flat-end back cover provides a rigid fixed rear mounting face for straightforward inline installation.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X250SU Is Used
PCB Component Placement
Uses 245 N of push at 0.5 MPa to shuttle electronic pick-and-place heads across a 250 mm axis within dense SMT machinery.
Bin Lid Actuation
Extends 250 mm to pop open compact sorting chute doors, where the U flat-end cover mounts rigidly to the machine subframe.
Lab Sample Routing
Moves fluidic test cartridges between analysis stations, relying on the -S magnet and DMSG electronic switch for timing.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X250SU the Right Cylinder?
This 25 mm bore generates 245 N push at 0.5 MPa. If your payload is lighter, step down to the 20 mm bore (157 N push); for heavier lifts, step up to the 32 mm bore (402 N push). The base MBL uses a fixed rubber bumper to soften end-of-stroke impact—upgrade to the MBLC variant if your cycle speed requires adjustable air cushioning. Because the cylinder relies on live air pressure, the rod will drift if air is lost or the valve is centered; use an external pilot-operated check valve if the load must be held.
At 250 mm of stroke, the Ø10 mm rod is highly susceptible to side-load bending. Prevent premature seal wear and rod bearing failure by guiding the load externally with a linear rail, or switch to the MBLD double-rod cylinder for anti-rotation support. Replacement match: 25 mm bore, 250 mm stroke, G1/8 port, PT thread, U flat-end back cover, -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 MBL25X250SU FAQ
At 0.5 MPa it provides 245 N push and 206 N pull force; at 0.7 MPa push increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. The double-acting speed range is 30-800 mm/s.
No, the base MBL25X250SU uses a fixed rubber bumper to absorb end-of-stroke impact, not an adjustable cushion screw. If your application requires tunable end-cushioning for faster cycles, select the MBLC variant.
