About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X100-CA
The AirTAC MBL25X100-CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa, making this 25mm bore, 100mm stroke unit ideal for light-duty positioning and part ejection. The riveted rolling-packed barrel permanently crimps the front and rear covers to the tube, yielding a lightweight body that is not designed to be disassembled like a tie-rod cylinder.
This specific SKU features a CA pivot (clevis) back cover that swings on a pin to accommodate arcing or angular loads. The carbon-steel piston rod is chrome-plated to 20 um for wear resistance, and the heterogeneous two-way piston seal retains grease for a long service life. Because this configuration lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X100-CA Is Used
PCB Depaneling Router
Drives a lightweight routing head across 100mm to singulate populated circuit boards, using the 245N push force to maintain steady feed without stalling.
Carton Flap Folder
Swings on its CA pivot bracket to fold minor box flaps on a packaging line, absorbing slight angular misalignment while cycling at 30-800 mm/s.
Connector Insertion Arm
Pushes D-sub connectors into PCB headers during electronics assembly, relying on the 20 um chrome-plated rod for smooth, repeatable linear motion.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X100-CA the Right Cylinder?
If you need less force, step down to the 20mm bore which provides 157 N of push at 0.5 MPa; if your application requires more power, step up to the 32mm bore delivering 402 N. The base MBL uses a fixed rubber bumper to soften end-of-stroke impact—choose the MBLC variant if you need an adjustable air cushion for heavier moving masses. Note that a plain MBL will not hold a load if air pressure is lost or the valve is centered; the rod will drift, so add an external pilot-operated check valve for position holding. This exact replacement matches a 25mm bore, 100mm stroke, G1/8 port, PT thread, CA pivot back cover, and 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 MBL25X100-CA FAQ
At 0.5 MPa, it provides 245 N of push force and 206 N of pull force. 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, not an adjustable air cushion (you would need the MBLC variant for that). Also, because this specific SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG sensor switches.
