About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X50SU
The AirTAC MBLC25X50SU is a compact double-acting aluminum mini cylinder providing 245 N of push force and 206 N of pull force at 0.5 MPa. Driven by a Ø10 mm carbon-steel rod with 20 um hard-chrome plating, the 50 mm stroke is well suited for short, rapid positioning tasks. Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic cushion at both ends. Tuning the needle valve lets you decelerate the piston smoothly near each stroke end, cutting end-cover impact and vibration on faster moves.
This SKU includes a built-in magnet (S) for CMSG, DMSG, or EMSG sensor switches to detect rod position along its travel. The riveted rolling-packed aluminum barrel keeps the body light and compact for tight machine spaces, while the heterogeneous two-way grease-retaining piston seal ensures consistent friction and lubrication. It uses a G1/8 port, a U flat-end back cover for rigid mounting, and PT tapered thread connections.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X50SU Is Used
PCB Depaneling Gate
Actuates a routing gate on an electronics assembly line, using the 50 mm stroke and 245 N force to shuttle boards with the adjustable cushion absorbing the rapid stop.
Connector Insertion Press
Drives a low-force press head to seat ribbon cable connectors into plastic housings, relying on the -S magnet to confirm the 50 mm stroke end before applying pressure.
Pharma Carton Flap Folder
Folds minor carton flaps on a compact packaging conveyor where the 25 mm bore fits tight clearances and the tuned air cushion prevents jarring impacts at 800 mm/s.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X50SU the Right Cylinder?
Select this 25 mm bore when an application demands 245 N push at 0.5 MPa but lacks the physical space for a larger unit. If your load requires less force, stepping down to the 20 mm bore yields 157 N push, whereas stepping up to the 32 mm bore provides 402 N push for heavier payloads. Choose the MBLC over the standard MBL when cycling speeds are high enough that a fixed rubber bumper would cause premature wear or unacceptable noise.
As a double-acting cylinder, this model relies on air pressure to both extend and retract; it will not hold position if air is lost or the valve centers, as the air cushion only decelerates near the ends and does not act as a brake. This specific configuration pairs a U flat-end back cover for rigid fixed mounting with a built-in magnet for position sensing, utilizing a PT port thread.
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 MBLC25X50SU FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N push and 206 N pull. At 0.7 MPa, it provides 343 N push and 289 N pull. The maximum theoretical force is 50 kgf at 1.0 MPa.
The cushion is a screw-tunable needle valve at both stroke ends that traps exhaust air to decelerate the piston smoothly. You tune it to match your load and speed, which protects the end covers from impact; it is a damping feature, not a load lock or brake.
