About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X25SCA
The AirTAC MBL25X25SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Generating 245 N of push force at 0.5 MPa, this 25 mm bore, 25 mm stroke unit is ideal for short, rapid positioning. The riveted rolling-packed barrel keeps the overall footprint small and lightweight, though it is not designed to be disassembled and rebuilt like a tie-rod cylinder.
This specific SKU includes a built-in magnet (-S) for use with AirTAC CMSG, DMSG, or EMSG sensor switches to detect rod position, and a CA pivot back cover. The CA clevis allows the cylinder body to swing on a pin, accommodating arcing or angular loads. Inside, 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 and corrosion resistance.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X25SCA Is Used
Textile Loom Guide
Swings on a pin via the CA pivot to perfectly track and tension moving fabric webs, using the 245 N push force to maintain alignment without stalling the drive.
PCB Router Gate
Uses the built-in magnet and a DMSG electronic sensor to confirm the 25 mm stroke position, rapidly opening a routing gate for circuit board transfer.
Pharma Carton Flap
Folds small cardboard flaps in tight packaging lines where the compact riveted aluminum body fits easily between moving conveyor belts.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X25SCA the Right Cylinder?
If your application requires less force, step down to the 20 mm bore MBL, which provides 157 N of push at 0.5 MPa. For heavier lifting, the 32 mm bore offers 402 N. The base MBL uses a fixed rubber bumper to soften end-of-stroke impact; for adjustable air cushioning at higher speeds or moving masses, specify the MBLC variant. Keep in mind the rubber bumper only absorbs shock and does not hold the load—this cylinder will drift if air pressure is lost or the valve is centered, so use an external rod lock or pilot-operated check valve if position holding is critical.
When replacing this unit, match the 25 mm bore, 25 mm stroke, G1/8 port, PT thread, CA pivot back cover, and the -S magnet. With a 10 mm piston rod and a 25 mm stroke, side-load tolerance is low; if your mechanism imposes lateral stress, ensure external guidance to prevent rod-bearing bending.
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 MBL25X25SCA FAQ
This 25 mm bore cylinder generates 245 N push and 206 N pull at 0.5 MPa, 343 N push at 0.7 MPa, and a maximum theoretical force of 50 kgf at 1.0 MPa.
No, the base MBL features a fixed rubber bumper to soften end-of-stroke impact, not an adjustable air cushion. If you need adjustable cushioning for heavier loads, select the MBLC variant.
