About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X60U
The AirTAC MBLC25X60U is a compact double-acting aluminum mini cylinder engineered for tight spaces, delivering a push force of 245 N and a pull force of 206 N at 0.5 MPa. Its 60 mm stroke is well suited for short, rapid positioning tasks. Unlike the base MBL series, this variant features a screw-adjustable pneumatic air cushion at both stroke ends, allowing you to precisely tune the end-of-stroke deceleration to match your specific load and velocity, thereby absorbing shock and protecting the end covers on high-frequency moves.
This model incorporates a Ø10 mm carbon-steel rod with 20 µm hard-chrome plating and a heterogeneous two-way grease-retaining piston seal to maintain lubrication over thousands of cycles. The riveted rolling-packed aluminum barrel keeps the overall body light and compact. The U designation indicates a flat-end back cover for rigid, straight-line mounting. Note that because this specific SKU lacks the S magnet suffix, it cannot support CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X60U Is Used
PCB Depanelling Ejector
Uses the 60 mm stroke to push singulated circuit boards out of a routing fixture, relying on the tuned air cushion to prevent the 245 N thrust from violently slamming the ejection plate against its hard stop.
Pharmaceutical Carton Flap Folding
Drives a small mechanical finger at high frequency to tuck carton flaps during packaging, where the adjustable end-cushioning ensures the 206 N retract force does not bounce the mechanism and misalign the box.
Connector Pin Insertion Press
Applies precise downward force to seat electronic header pins into plastic housings, utilizing the 25 mm bore's compact size and smooth pneumatic deceleration to protect delicate mating components from end-stroke impact.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X60U the Right Cylinder?
Select this 25 mm bore when an application requires 245 N of push force at 0.5 MPa but lacks the physical envelope for a larger 32 mm unit (which provides 402 N). Conversely, if your load demands less energy, stepping down to the 20 mm bore yields 157 N in a tighter footprint. Choose the MBLC over the standard MBL when cycle speeds are high enough that the fixed rubber bumper would wear prematurely or cause excessive impact noise. The adjustable cushion needle lets you dial in the exact deceleration curve, though it functions strictly as a shock absorber and not a load lock—the rod will drift if air pressure is lost or the valve centers. For exact replacement matching, verify the 60 mm stroke, G1/8 port, PT thread, U flat-end back cover, and the absence of a 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 MBLC Aluminum Alloy Mini Air Cylinder MBLC25X60U 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, the push increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. It operates on filtered air between 0.15 and 1.0 MPa, supports speeds of 30-800 mm/s, and uses a G1/8 port with an M10x1.25 rod thread.
No, this specific SKU lacks the built-in magnet required for AirTAC CMSG, DMSG, or EMSG sensor switches. Regarding the cushion, it features a screw-adjustable pneumatic needle at both ends that traps exhaust air to decelerate the piston smoothly near the stroke ends. You tune this needle to match your load and speed, which reduces impact noise and wear compared to a fixed rubber bumper, but it does not lock the rod in place.
