About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X55SCA
The AirTAC MBL25X55SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a push force of 245 N and a pull force of 206 N at 0.5 MPa, making it well-suited for short 55 mm actuation tasks. The riveted rolling-packed barrel keeps the body light and small, though it is not designed to be disassembled like a tie-rod cylinder. A heterogeneous two-way piston seal retains grease internally for long service life.
This specific SKU features a built-in magnet (-S) for compatibility with AirTAC CMSG, DMSG, and EMSG sensor switches to detect rod position. It is equipped with a CA pivot (clevis) back cover, allowing the cylinder to swing on a pin to accommodate arcing or angular loads. The Ø10 mm carbon-steel piston rod features 20 µm hard-chrome plating for wear and corrosion resistance. End-of-stroke impact is absorbed by a fixed rubber bumper rather than an adjustable air cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X55SCA Is Used
Textile Yarn Guide
Swings on a pin via the CA clevis to pivot a yarn guide across a weaving loom, using the 245 N push force to maintain tension without stalling.
PCB Reject Arm
Uses the built-in magnet with a DMSG solid-state sensor to confirm the 55 mm stroke position when pushing defective printed circuit boards off an SMT line.
Carton Flap Folder
Pivots to follow a moving packaging conveyor, folding small carton flaps with 206 N pull force where a rigid mount would bind the mechanism.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X55SCA the Right Cylinder?
For slightly lower force needs, step down to the 20 mm bore, which provides 157 N push at 0.5 MPa. If your application requires greater thrust, step up to the 32 mm bore, offering 402 N push at 0.5 MPa. The base MBL uses a fixed rubber bumper; if your cycle speeds increase and you need an adjustable air cushion to soften end-of-stroke impacts, specify the MBLC variant. If the load must be held without live air pressure, note that the rubber bumper is not a lock or brake—the rod will drift or drop when the valve is centered; use an external rod lock or pilot-operated check valve.
This SKU's exact replacement match is: 25 mm bore, 55 mm stroke, G1/8 port (PT thread form), CA pivot back cover, no mounting accessory specified, with a built-in magnet (-S).
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 MBL25X55SCA FAQ
At 0.5 MPa, the push force is 245 N and the pull force is 206 N. 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 to soften end-of-stroke impact. It is not an adjustable cushion screw. If you need adjustable air cushioning for heavier or faster loads, use the MBLC variant.
