About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X20SCA
The AirTAC MBL25X20SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. With a 25mm bore and 20mm stroke, it generates 245 N of push force and 206 N of pull force at 0.5 MPa. The riveted rolling-packed aluminum barrel keeps the body light and small, though it is not designed to be disassembled like a tie-rod cylinder. This specific SKU includes a built-in magnet (-S) for use with AirTAC CMSG, DMSG, and EMSG sensor switches to track rod position.
This model features a CA pivot back cover, allowing the cylinder to swing on a pin to accommodate arcing or angular loads. Unlike a rigid flat-end mount, the clevis design prevents binding during lateral movement. The carbon-steel piston rod features 20 µm hard-chrome plating for wear and corrosion resistance, paired with a heterogeneous two-way piston seal that retains grease for long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X20SCA Is Used
PCB Shuttle Transfer
Ideal for pivoting small electronic PCB trays between test stations using the CA clevis, where the 245 N push force easily shifts light jigs along an arcing path.
Component Sorting Gate
Swings a diverter gate on a chip sorting line; the built-in magnet works with a DMSG solid-state sensor to confirm the 20mm stroke position for high-speed cycling.
Pouch Sealing Press
Applies downward clamping pressure on a small packaging jaw, using the 206 N pull force to hold the seal bar while the CA pivot absorbs minor jaw misalignment.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X20SCA the Right Cylinder?
If you need less force, step down to the 20mm bore (157 N push @0.5 MPa); if your application requires more thrust, step up to the 32mm bore (402 N push @0.5 MPa). The base MBL uses a fixed rubber bumper to soften end-of-stroke impact—if your cycle speed demands adjustable air cushioning for heavier loads, select the MBLC variant. Remember that a plain MBL does not hold its load when air pressure is lost or exhausted; the rod will drift. Use an external rod lock or pilot-operated check valve if position holding is critical.
This exact replacement match is defined by: 25mm bore, 20mm stroke, G1/8 port size, PT port thread, CA pivot back cover, and a built-in magnet (-S). Because this is a short 20mm stroke, side-load bending on the 10mm rod is minimal, but for longer arcs, ensure the pivot pin is aligned to prevent side stress.
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 MBL25X20SCA FAQ
At 0.5 MPa it provides 245 N push and 206 N pull; at 0.7 MPa it pushes 343 N, with a maximum theoretical force of 50 kgf at 1.0 MPa. This model uses a fixed rubber bumper for end-of-stroke impact absorption, not an adjustable air cushion (the MBLC variant offers adjustable cushioning).
Yes, the -S suffix indicates a built-in magnet. It is designed to work with AirTAC CMSG (reed), DMSG, and EMSG (electronic) sensor switches for rod position detection. Without the -S suffix, a standard MBL cylinder cannot accept any sensor.
