About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X50SCA
The AirTAC MBL25X50SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. At 0.5 MPa it provides 245 N of push force and 206 N of pull force, making it well-suited for 50 mm stroke actuation in small part routing and light clamping. The riveted rolling-packed aluminum barrel keeps the body light and small, but unlike a tie-rod cylinder, it is not designed to be disassembled and rebuilt in the field.
This specific SKU includes a built-in magnet (-S) for position sensing via AirTAC CMSG reed or DMSG/EMSG electronic switches. It also features a CA pivot (clevis) back cover, allowing the cylinder body to swing on a pin to absorb arcing and angular loads. The carbon-steel piston rod is hardened with 20 µm chrome plating for wear resistance, and a heterogeneous two-way piston seal retains grease for long operational life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X50SCA Is Used
Pick-and-Place Swing Arms
Ideal for routing small electronic components on a rotary swing arm where the CA pivot back cover accommodates the arcing motion and the 245 N force drives the 50 mm transfer stroke.
Packaging Flap Folding
Provides reliable 50 mm travel for folding light cardboard flaps on compact packaging lines, with the built-in magnet confirming retraction for the sequencer.
Conveyor Divert Gates
Pushes small product cartons at 245 N onto secondary conveyor tracks, using the pivot mount to self-align under minor side-loads.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X50SCA the Right Cylinder?
If you need less force, the neighbouring Ø20 bore offers 157 N push at 0.5 MPa, while stepping up to the Ø32 bore yields 402 N push. Because this is a base MBL, end-of-stroke deceleration relies on a fixed rubber bumper rather than an adjustable air cushion; choose the MBLC variant if your application requires adjustable cushioning for heavier moving masses. Note that a plain MBL will not hold a load if air pressure is lost or exhausted—the rod will drift. Use an external pilot-operated check valve or rod lock if position holding is critical. For replacement, match the 25 mm bore, 50 mm stroke, G1/8 port, PT thread, CA pivot back cover, and the -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 MBL25X50SCA FAQ
At 0.5 MPa, this 25 mm bore cylinder outputs 245 N push and 206 N pull force. At 0.7 MPa, the push force is 343 N, with a theoretical maximum of 50 kgf at 1.0 MPa. The operational speed ranges from 30-800 mm/s.
No, the base MBL features a fixed rubber bumper at the end of stroke to soften impact, not an adjustable cushion screw. If you need adjustable air cushioning for faster cycles or heavier loads, you must step up to the MBLC variant.
