About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X100SU
The AirTAC MBL25X100SU is a double-acting aluminum mini round cylinder engineered for compact machinery where space is at a premium. Delivering 245 N of push force and 206 N of pull force at 0.5 MPa, this 25 mm bore, 100 mm stroke unit handles light-duty positioning with efficiency. The riveted rolling-packed barrel permanently crimps the front and rear covers to the tube, yielding a featherweight body that slips easily into dense automation layouts.
This specific SKU includes a built-in magnet (-S) for direct compatibility with AirTAC CMSG reed and DMSG/EMSG electronic sensor switches, enabling precise end-of-stroke detection. It uses a U-type flat-end back cover for rigid fixed mounting. The carbon-steel piston rod features 20 µm hard-chrome plating to resist wear, while the heterogeneous two-way piston seal retains grease for a long, maintenance-free service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X100SU Is Used
PCB Router Gating
Actuates a small diverter gate on a printed circuit board routing line, using the 245 N thrust to push lightweight carriers laterally without stalling.
Blister Pack Indexer
Drives a 100 mm stroke pitch arm to advance pharmaceutical blister packaging film through a sealing press in confined cleanroom cabinets.
Microplate Handler
Positions a vacuum pickup head over a 96-well microplate in a diagnostic analyzer, relying on the integrated magnet for DMSG sensor confirmation.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X100SU the Right Cylinder?
If your application requires less force, stepping down to the 20 mm bore yields 157 N of push at 0.5 MPa; conversely, moving up to the 32 mm bore provides 402 N. At 100 mm of stroke, the Ø10 mm rod is moderately exposed, so keeping the load axially aligned prevents premature seal wear. This cylinder relies on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion—choose the MBLC variant if your cycle rates demand tunable deceleration. Note that a plain MBL cannot hold a load safely if air pressure drops; integrate an external pilot-operated check valve if position retention is required upon power loss. The direct replacement match is a 25 mm bore, 100 mm stroke, G1/8 port, PT thread, U flat-end back cover, with 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 MBL25X100SU FAQ
At 0.5 MPa it provides 245 N push and 206 N pull; at 0.7 MPa the push increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa with a speed range of 30-800 mm/s.
No, the base MBL uses a fixed rubber bumper to absorb end-of-stroke impact, not an adjustable cushion screw. If your application involves heavy moving masses or high speeds requiring tunable deceleration, upgrade to the MBLC variant.
