About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X50SU
The AirTAC MBL25X50SU is a double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a 245 N push force at 0.5 MPa, making it well-suited for short 50 mm stroke movements in compact assemblies. This specific SKU includes a U-type flat-end back cover for rigid rear mounting and a built-in magnet (-S) for position detection.
Unlike tie-rod cylinders, the MBL features a riveted rolling-packed barrel that crimps the covers directly to the tube, minimizing weight and footprint. The carbon-steel piston rod is plated with 20 µm hard chrome to resist wear and corrosion, while a heterogeneous two-way piston seal retains grease for a long service life. End-of-stroke energy is absorbed by a fixed rubber bumper rather than an adjustable cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X50SU Is Used
PCB Router Gating
Pushing a small pneumatic gate to route printed circuit boards into testing trays using 245 N of push force within a densely packed electronics assembly cell.
Carton Flap Folding
Folding small cardboard flaps on a compact packaging line, where the 50 mm stroke and rigid U-type back cover provide precise, stable end-positioning.
Lab Vial Sorting
Diverting glass vials into sorting chutes on a clinical analyzer, using the built-in magnet and a DMSG solid-state switch to verify the 50 mm extend position.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X50SU the Right Cylinder?
If you need less force, the neighboring 20 mm bore provides 157 N push at 0.5 MPa; for heavier payloads, the 32 mm bore steps up to 402 N. Choose the MBLC variant if your application requires an adjustable air cushion to soften heavier end-of-stroke impacts. The U-type flat-end back cover on this unit provides a rigid fixed mount, whereas a CA pivot cover would be better for arcing loads.
Because this is a double-acting cylinder, it relies on live air pressure to hold position; if air is lost, the rod will drift. The fixed rubber bumper softens end-stroke impacts but does not function as a lock, so use an external rod lock or pilot-operated check valve if the load must be held. Replacement parts must match the 25 mm bore, 50 mm stroke, G1/8 port, PT thread, U back cover, and -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 MBL25X50SU FAQ
At 0.5 MPa, it provides 245 N push and 206 N pull force. At 0.7 MPa, the push force is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
No, the base MBL uses a fixed rubber bumper, not an adjustable air cushion (which requires the MBLC variant). Additionally, it does not hold loads if air pressure is lost; the rod will drift without live pressure.
