About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X125-CA
The AirTAC MBL25X125-CA is a double-acting aluminum mini round cylinder engineered for compact spaces. It delivers a 245 N push force at 0.5 MPa across a 125 mm stroke, making it suitable for mid-range linear actuation. The riveted rolling-packed body keeps weight down but is not designed to be disassembled like a tie-rod cylinder. This genuine AirTAC component features a carbon-steel rod with 20 μm hard-chrome plating for high wear and corrosion resistance.
This SKU includes a CA pivot back cover, allowing the cylinder to swing on a pin for arcing or angular loads. It relies on a fixed rubber bumper to soften end-of-stroke impact rather than an adjustable air cushion. Because this specific model lacks the -S magnet suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X125-CA Is Used
Textile Loom Guide
Actuates a thread guide arm on a weaving loom, using the CA pivot mount to accommodate the arcing travel path while applying 245 N of force.
Package Flap Diverter
Swings a diverter flap on a packaging conveyor to sort small cartons, benefiting from the compact 25 mm bore footprint in tight transfer zones.
Bin Lid Release
Pivots a hinged lid on an assembly line parts bin, where the 125 mm stroke provides sufficient clearance for component dispensing.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X125-CA the Right Cylinder?
With a 245 N push at 0.5 MPa, stepping down to the 20 mm bore drops output to 157 N, while moving up to the 32 mm bore raises it to 402 N. For faster or heavier moves requiring end-deceleration, select the MBLC variant with adjustable air cushioning. If you need push or pull single-acting operation, consider the MSBL or MTBL (bores 20-40). This CA pivot model is ideal for arcing loads, but note that the plain MBL does not hold position when air pressure is lost; use an external rod lock or pilot-operated check valve for fail-safe load holding. Replacement matches: 25 mm bore, 125 mm stroke, G1/8 port, PT thread, CA back cover, no 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 MBL25X125-CA FAQ
At 0.5 MPa it pushes 245 N and pulls 206 N; at 0.7 MPa it pushes 343 N, with a maximum theoretical force of 50 kgf at 1.0 MPa. Because this SKU lacks the -S suffix, it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG sensor switches.
The base MBL uses a fixed rubber bumper to absorb end-of-stroke impact. It does not have an adjustable cushion screw; for adjustable air cushioning, you must step up to the MBLC variant.
