About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X30U
The AirTAC MBLC25X30U is a compact double-acting aluminum mini cylinder featuring a 25mm bore and 30mm stroke. It delivers 245N of push force and 206N of pull force at 0.5MPa. The U designation indicates a standard rigid flat-end back cover, ideal for straightforward rigid mounting. This short 30mm stroke is tailored for very compact, rapid positioning tasks.
Unlike the base MBL series which relies on a fixed rubber bumper, this MBLC variant incorporates a screw-adjustable pneumatic air cushion at both stroke ends. Tuning the cushion needle allows you to smoothly decelerate the piston, reducing impact shock and vibration on fast moves. The riveted rolling-packed aluminum barrel keeps the body light and compact, while the Ø10mm carbon-steel rod features 20µm hard-chrome plating to resist wear. Note that this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X30U Is Used
PCB Depaneling Saw
Provides a fast 30mm push at 245N to advance a depaneling blade through circuit boards, using the tunable cushion to soften the stroke end and protect the blade alignment.
Pharma Carton Flap
Closes small pharmaceutical carton flaps with a precise short stroke, where the adjustable air cushion prevents crushing the lightweight packaging material.
Connector Insertion
Presses electronic pin headers into housings with 206N pull force, relying on the compact 25mm body to fit within dense PCB assembly automation.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X30U the Right Cylinder?
For lower force requirements, stepping down to the 20mm bore yields 157N push at 0.5MPa, whereas moving up to the 32mm bore provides 402N. Choose this MBLC model over the fixed-bumper MBL when your application cycles rapidly and requires smooth end-of-stroke deceleration to protect the end covers. Keep in mind that the air cushion only decelerates the piston near the ends; it is not a locking mechanism, so the rod will drift if air pressure is lost.
This replacement SKU features a 25mm bore, 30mm stroke, G1/8 port, PT thread, U flat-end back cover, and no magnet. If position feedback is required, select the -S variant to enable CMSG reed or DMSG/EMSG electronic sensors.
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 MBLC Aluminum Alloy Mini Air Cylinder MBLC25X30U FAQ
The 25mm bore generates 245N push and 206N pull at 0.5MPa, or 343N push at 0.7MPa, with a maximum theoretical force of 50kgf at 1.0MPa. It uses a G1/8 port, a Ø10mm rod with an M10x1.25 rod-end thread, and PT tapered port threads.
No, this specific MBLC25X30U SKU does not have a built-in magnet, so CMSG, DMSG, or EMSG sensor switches cannot be used. To add a reed or electronic solid-state sensor, select the MBLC25X30SU version.
