About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X250SCA
The AirTAC MBLC25X250SCA is a double-acting, single-rod aluminum mini cylinder engineered for compact actuation. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa, utilizing a 10 mm carbon-steel rod with 20 µm hard-chrome plating to resist corrosion and seal wear. A built-in magnet (-S) enables direct mounting of CMSG, DMSG, or EMSG sensor switches for precise end-of-stroke detection.
This 250 mm stroke variant features a CA pivot/clevis back cover, allowing the body to swing freely on a pin to accommodate arcing angular loads without binding. Unlike the base MBL which relies on a fixed rubber bumper, the MBLC incorporates a screw-adjustable pneumatic air cushion at both ends. You can tune the exhaust needle to smoothly decelerate the piston near the stroke ends, effectively absorbing kinetic energy to reduce impact shock, noise, and vibration during fast or frequent cycling.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X250SCA Is Used
Textile Loom Guide
Swings via the CA clevis to thread and tension yarn on a weaving loom, using the 245 N push force and tuned end-cushions to prevent sudden jerks that would snap fine fibers.
Packaging Flap Diverter
Pivots a routing flap on a high-speed carton erector, where the 250 mm stroke moves the gate fully across the belt and the air cushion softens the 800 mm/s impact to protect the mechanism.
Warehouse Sorter Arm
Acts as a pusher arm on a parcel diverter, relying on the built-in magnet for DMSG sensor confirmation and the adjustable cushion to survive thousands of rigid hourly cycles.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X250SCA the Right Cylinder?
For applications needing less reach and force, the 20 mm bore provides 157 N push at 0.5 MPa; if higher thrust is required, the 32 mm bore offers 402 N. The 250 mm stroke on this 10 mm rod demands careful side-load management, as small rods have low bending tolerance—always pair this length with an external guide rail, the CA pivot, or a double-rod MBLCD to prevent binding. The adjustable cushion is ideal for heavier or high-speed moves where a fixed bumper would fail, but note it only decelerates near the ends and will not hold a load if air pressure drops. Direct replacement match: 25 mm bore, 250 mm stroke, G1/8 port, PT thread, CA back cover, magnet included.
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 MBLC25X250SCA 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 theoretical maximum force is 50 kgf at 1.0 MPa operating pressure.
A screw-tunable needle at each end cover restricts exhaust air flow, creating a pneumatic back-pressure that decelerates the piston smoothly before it hits the end. This is superior to a fixed rubber bumper for high-speed or heavy loads, but it is strictly an end-of-stroke damper, not a locking brake.
