About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X10U
The AirTAC MBLC25X10U is a compact double-acting aluminum mini cylinder engineered for tight spaces, delivering 245 N of push force and 206 N of pull force at 0.5 MPa. Its defining feature is the screw-adjustable pneumatic cushion at both ends, which smoothly decelerates the piston near the stroke limits to reduce impact and vibration. This 10 mm stroke variant is ideal for very short, rapid positioning tasks.
Unlike the base fixed-bumper design, this model allows you to tune the end-of-stroke deceleration to match your load and speed, protecting the end covers on high-frequency moves. It features a riveted rolling-packed aluminum barrel for a lightweight, compact profile, and a 20 µm hard-chrome plated carbon-steel rod paired with a heterogeneous two-way grease-retaining piston seal. 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 MBLC25X10U Is Used
PCB Router Clamping
Provides 245 N of clamping force at 0.5 MPa to hold delicate printed circuit boards during high-speed routing, using the 10 mm stroke to secure panels in milliseconds.
Pick-and-Place Jaw Actuation
Drives small gripper jaws on surface mount machines, where the tunable cushion prevents end-cap shock on rapid 10 mm excursions between component feeders.
Carton Flap Folding
Executes quick 10 mm folding tucks on small packaging lines, using 206 N of pull force to retract the mechanism before the next product arrives.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X10U the Right Cylinder?
With a 10 mm stroke and 245 N push force at 0.5 MPa, this cylinder suits very short, rapid cycles. If you need less force, the neighbouring 20 mm bore provides 157 N of push, while stepping up to the 32 mm bore yields 402 N for heavier duties. Choose this MBLC version over the standard MBL when your cycle speeds are high enough that a fixed rubber bumper would wear prematurely. Remember that the adjustable air cushion only decelerates the piston near the ends; it does not lock the rod, so an external rod lock is required to hold position without live air. Replacement match: 25 mm bore, 10 mm stroke, G1/8 port, PT thread, U flat-end back cover, 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 MBLC Aluminum Alloy Mini Air Cylinder MBLC25X10U 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, with an operating pressure range of 0.15-1.0 MPa and a speed range of 30-800 mm/s.
The MBLC25X10U uses a screw-adjustable pneumatic needle at both ends instead of a fixed rubber bumper. You tune the needle to trap exhaust air, creating a deceleration cushion that matches your load and speed. This protects the end covers from impact during fast, high-frequency cycles, though it acts only near the stroke ends and does not function as a load lock.
