About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X75SU
The AirTAC MBLC25X75SU is a double-acting aluminum mini cylinder engineered for compact setups needing precise end-of-stroke control. It generates 245 N of push force and 206 N of pull force at 0.5 MPa across a 75 mm stroke. A screw-adjustable pneumatic cushion at both ends decelerates the piston smoothly, cutting impact and noise on faster or heavier moves compared to a fixed rubber bumper.
This SKU features a built-in magnet (-S) for CMSG, DMSG, or EMSG sensor switches, a flat-end U back cover for rigid mounting, and PT thread. The riveted rolling-packed barrel keeps the body light, while the Ø10 mm carbon-steel rod with 20 µm hard-chrome plating resists wear. A heterogeneous two-way grease-retaining piston seal maintains consistent lubrication over its 30-800 mm/s operating speed range.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X75SU Is Used
PCB Router Gating
Directs printed circuit boards down a testing lane using 245 N of push force, relying on the adjustable air cushion to silently stop the 75 mm stroke without jarring delicate solder joints.
Pharmaceutical Carton Diverting
Pushes lightweight medical packaging cartons at high frequency, using the tunable end-cushion to prevent rebound while the internal magnet triggers a DMSG solid-state sensor for timing.
Small-Part Ejection
Ejects machined plastic components from a tight fixture, where the compact riveted aluminum barrel fits neatly within the machine frame and the U flat-end cover provides rigid anti-rotation mounting.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X75SU the Right Cylinder?
Select this 25 mm bore when your application requires 245 N of thrust at 0.5 MPa but lacks the physical space for a larger unit. If you need less force, stepping down to the 20 mm bore provides 157 N of push, whereas upgrading to the 32 mm bore yields 402 N for heavier payloads. The adjustable air cushion justifies choosing this MBLC over the base MBL when cycle speeds are high and a fixed bumper cannot adequately absorb the kinetic energy.
Because the 75 mm stroke is relatively short, side-load stress on the Ø10 mm rod is minimal, but you must still align loads carefully to avoid seal wear. Note that the pneumatic cushion only decelerates the piston near the stroke ends; it does not function as a brake or lock. If the air supply is lost or the valve centers, the rod will drift, so fit an external rod lock or pilot-operated check valve for strict position holding. This exact replacement matches: 25 mm bore, 75 mm stroke, G1/8 port, PT thread, U flat-end back cover, and an -S magnet.

- ✓ 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 MBLC25X75SU FAQ
This 25 mm bore cylinder uses a G1/8 port and a Ø10 mm rod. At 0.5 MPa it pushes with 245 N and pulls with 206 N. At 0.7 MPa the push increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
A screw-tunable needle at both end covers traps a small pocket of exhaust air to decelerate the piston smoothly before it strikes the end cap. You adjust the needle to match your specific load and speed, which is critical for high-cycle machines where a fixed rubber bumper would wear out quickly. It is strictly a deceleration device, not a load lock.
