About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X350SCA
The AirTAC MBL25X350SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a 245 N push force at 0.5 MPa across a 350 mm stroke. The riveted rolling-packed barrel permanently crimps the front and rear covers to the tube, yielding a lightweight footprint that is not designed to be disassembled like a tie-rod body. A heterogeneous two-way piston seal retains grease for long service life, while the carbon-steel rod features 20 µm hard-chrome plating for wear resistance.
This specific SKU includes a built-in magnet (-S) for mounting AirTAC CMSG (reed) or DMSG/EMSG (electronic) sensor switches to detect rod position. It is fitted with a CA pivot back cover, allowing the cylinder body to swing on a pin to accommodate arcing or angular loads. The base MBL uses a fixed rubber bumper to soften end-of-stroke impact; for adjustable air cushioning, the MBLC variant is required.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X350SCA Is Used
Textile Loom Guide Arm
Swings a thread guide arm across a 350 mm arc. The CA pivot back cover handles the angular load, while the 245 N push force at 0.5 MPa reliably shifts the mechanism.
Packaging Diverter Flap
Pivots a cardboard diverter gate on a packaging line. The built-in magnet works with a DMSG sensor to confirm flap position, and the compact aluminum body fits the tight conveyor frame.
Bin Tilting Mechanism
Tilts a small parts bin to dump components into a secondary hopper. The 350 mm stroke provides the necessary reach, and the fixed rubber bumper absorbs the shock of the full bin stopping.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X350SCA the Right Cylinder?
If you need less force, step down to the 20 mm bore (157 N push @0.5 MPa); if your application requires more power, step up to the 32 mm bore (402 N push @0.5 MPa). Because this is a 350 mm stroke, the 10 mm rod has limited side-load tolerance and can bend under lateral stress—use an external guide, the CA pivot mount, or an MBLD double-rod cylinder to prevent rod-bearing damage. The fixed rubber bumper only softens end-of-stroke impact; it is not a lock, so the rod will drift or drop if air pressure is lost. To hold a load safely without live pressure, use an external rod lock or pilot-operated check valve. Replacement match: 25 mm bore, 350 mm stroke, G1/8 port, PT thread, CA back cover, built-in 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 MBL25X350SCA 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 MBL25X350SCA uses a fixed rubber bumper to absorb end-of-stroke impact and is not adjustable. If your application requires adjustable air cushioning for heavier or faster loads, you must use the MBLC variant.
