About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X50U
The AirTAC MBLC25X50U is a double-acting aluminum mini cylinder featuring a 25 mm bore and a 50 mm stroke. It generates 245 N of push force and 206 N of pull force at 0.5 MPa, making it well-suited for compact mid-range actuation. Unlike the base MBL series, this variant utilizes a screw-adjustable pneumatic cushion at both stroke ends. You can tune the needle valve to smoothly decelerate the piston, absorbing kinetic energy to reduce end-cover impact and vibration during faster cycling.
This SKU is configured with a U flat-end back cover for rigid, straight-line mounting. It features a G1/8 port and a Ø10 mm carbon-steel rod with 20 µm hard-chrome plating to resist wear. The riveted rolling-packed aluminum barrel keeps the body light and compact for tight spaces. Note that this specific model lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensing without a physical switch rail.
When selecting this actuator, consider stepping down to the 20 mm bore if your application requires only 157 N of push force at 0.5 MPa, or stepping up to the 32 mm bore if you need 402 N to handle heavier loads. Choose the MBLC over the standard MBL when your machine runs at higher speeds or frequencies and the fixed rubber bumper would wear out too quickly. Remember that the adjustable air cushion only decelerates the piston near the ends; it is not a brake and will not hold the rod in place if air pressure is lost. For exact physical dimensions and weight, confirm from datasheet.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X50U Is Used
PCB Depaneling Saw
Pushes a carrier fixture smoothly at speed, using the adjustable cushion to prevent jarring stops that could damage delicate printed circuit board edges.
Pharmacy Bag Dispenser
Actuates a paper feed mechanism in a compact kiosk where the 245 N force is sufficient and the U flat-end cover provides rigid mounting.
Connector Pick-and-Place
Handles delicate electronic connectors, relying on the tuned end-of-stroke deceleration to prevent parts from bouncing off the gripper during transfer.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X50U the Right Cylinder?
When sizing this actuator, consider stepping down to the 20 mm bore if your application requires only 157 N of push force at 0.5 MPa, or stepping up to the 32 mm bore if you need 402 N to handle heavier loads.

- ✓ 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 MBLC25X50U FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N of push force and 206 N of pull force. At 0.7 MPa, push increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. It uses a G1/8 port and a Ø10 mm rod.
No, this specific SKU does not have a built-in magnet (indicated by the absence of an 'S' in the model code), so it cannot support AirTAC CMSG, DMSG, or EMSG sensor switches. You would need the MBLC25X50S variant for position detection.
